This presentation will explain about spring and hibernate integration based on Java config. moreover, this presentation has a detailed explanation of spring and hibernate integration.
This presentation is about Spring MVC. Topics covered in this session are:
1. HTTP Servlet
2. What is Spring MVC?
3. MVC Architecture
4. Request Processing Workflow in Spring MVC
5. Spring Web Application Context
6. Spring MVC Configuration
7. Important Annotations
University of Colorado PhD software engineering student Aaron Schram explains the details of creating a web applications using the Spring MVC framework
In this presentation I will go through latest features being added in Spring 3.1/3.2 one more time and also will try to look behind the scene on what new features are comming in Spring 4 which should be released at the end of this year.
This session will provide a complete tour of using the Spring MVC framework to build Java Portlets. It will include an in-depth review of a sample portlet application developed using the latest features of Spring MVC, including Annotation-based Controllers. If you are writing Portlets and using Spring, this session is for you.
We'll begin by discussing the unique differences and challenges when developing Portlets instead of traditional Servlet webapps. Then we'll talk about the unique approach that Spring MVC takes towards Portlets that fully leverages the Portlet lifecycle, instead of masking it like many other frameworks. We'll take an extensive tour of a sample application so we can see all the unique pieces of the framework in action. Finally we'll conclude with discussion of the upcoming support for the Portlet 2.0 (JSR 286) specification that will be part of Spring 3.0.
Starting with Spring MVC 2.5, Annotation-Based Controllers became the preferred model for development (the Interface-based Controller hierarchy will be deprecated in Spring 3). This session will teach developers familiar with the old model how to use the new Annotation-based Controllers. This will also provide the basis for writing JSR 286 portlets using Spring 3.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Source : https://spring.io/projects/spring-framework#overview
11. Introduction to the Spring Framework
The Spring Framework
consists of features
organized into about 20
modules.
12. Core Technologies
Configuration metadata represents how you as an application developer tell the
Spring container to instantiate, configure, and assemble the objects in your
application.
Configuration metadata is traditionally supplied in a simple and intuitive XML
format.
13. XML-based configuration
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="accountDao"
class="org.springframework.samples.jpetstore.dao.jpa.JpaAccountDao">
<!-- additional collaborators and configuration for this bean go here -->
</bean>
<bean id="itemDao" class="org.springframework.samples.jpetstore.dao.jpa.JpaItemDao">
<!-- additional collaborators and configuration for this bean go here -->
</bean>
<!-- more bean definitions for data access objects go here -->
14.
15. XML-based metadata is not the only allowed form
of configuration metadata
Annotation-based configuration: Spring 2.5 introduced support for
annotation-based configuration metadata.
Java-based configuration: Starting with Spring 3.0, many features provided by
the Spring JavaConfig project became part of the core Spring Framework
18. Spring Java Configuration Advantages
1. Easy to understand
2. Java is type safe. Compiler will report issues if you are configuring right bean
class qualifiers.
3. XML based on configuration can quickly grow big.
4. Search is much simpler, refactoring will be easier. Finding a bean definition
will be far easier.
5. etc,etc…….
25. MVC
Model:-
Applications business logic is contained within the model and is responsible for maintaining data.
View: - It represents the user interface, with which the end user communicates. In short all the user
interface logic is contained within the VIEW
Controller:-It is the controller that answers to user actions. Based on the user actions, the respective
controller responds within the model and chooses a view to render that display the user interface. The
user input logic is contained with-in the controller
28. ● Any incoming request that comes to the web
application will be sent to Front Controller
(Dispatcher Servlet)
● Front Controller decides to whom (Controller) it
has to hand over the request, based on the
request headers.
● Controller that took the request, processes the
request, by sending it to suitable service class.
● After all processing is done, Controller receives
the model from the Service or Data Access layer.
● Controller sends the model to the Front Controller
(Dispatcher Servlet).
● Dispatcher servlet finds the view template, using
view resolver and send the model to it.
● Using View template, model and view page is build
and sent back to the Front Controller.
● Front controller sends the constructed view page
to the browser to render it for the user requested.
29. Web.xml (No need in Java config)
<web-app>
<servlet>
<servlet-name>example</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>example</servlet-name>
<url-pattern>/example/*</url-pattern>
</servlet-mapping>
</web-app>
30. Root Config Classes are actually used to
Create Beans which are Application Specific
and which needs to be available for Filters (As
Filters are not part of Servlet).
Servlet Config Classes are actually used to
Create Beans which are DispatcherServlet
specific such as ViewResolvers,
ArgumentResolvers, Interceptor, etc.
Root Config Classes will be loaded first and
then Servlet Config Classes will be loaded.
Root Config Classes will be the Parent Context
and it will create a ApplicationContext
instance. Where as Servlet Config Classes will
be the Child Context of the Parent Context and
it will create a WebApplicationContext instance.
31. package hms.config.spring.mvc;
import hms.config.hibernate.AppContext;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class AppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[]{AppContext.class};
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[]{WebMVCConfig.class};
}
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
}
Recommended way to set up Spring MVC application
32. Spring MVC Configuration
package hms.config.spring.mvc;
import ...
@Configuration
@EnableWebMvc
@ComponentScans({
@ComponentScan("hms.controller"),
@ComponentScan("dao"),
@ComponentScan("hms.service")
})
public class WebMVCConfig implements WebMvcConfigurer {
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/pages/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
33. Spring MVC Configuration continue
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry
.addResourceHandler("/resources/**")
.addResourceLocations("/resources/");
}
}
For example – the following line will serve all requests for resources coming in with a public
URL pattern like “/resources/**” by searching in the “/resources/” directory under the root
folder in our application.
<mvc:resources mapping="/resources/**" location="/resources/" />
34. Bean overview
A Spring IoC container manages one or more beans. These beans are created
with the configuration metadata that you supply to the container, for example, in
the form of XML definitions.
The objects that form the backbone of application and that are managed by the
Spring IoC container are called beans
<!-- A simple bean definition -->
<bean id = "..." class = "...">
<!-- collaborators and configuration for this bean go here -->
</bean>
41. Hibernate ORM
Hibernate ORM is an object-relational mapping tool for the Java programming
language. It provides a framework for mapping an object-oriented domain model
to a relational database
Hibernate's primary feature is mapping from Java classes to database tables, and
mapping from Java data types to SQL data types.
42. What is ORM ?
ORM = Object-
relational mapping
43. Advantages of ORM
● Speeding development
● No need to deal with database implementations
● Efficient
● DB independence
44. Hibernate Overview
● Initial release : 23 May 2001; 17 years ago
● Hibernate 5.2 and later versions require at least Java 1.8 and JDBC 4.2.
○ I used 5.3.5.Final
● Hibernate does not require an application server to operate.
45. Java Database Connectivity (JDBC) is an application programming
interface (API) for the programming language Java
The Java Persistence API (JPA) is a Java application programming
interface specification that describes the management of relational
data in applications using Java Platform, Standard Edition and Java
Platform, Enterprise Edition.
46. Let’s handover Hibernate to Spring
The benefits of using the Spring Framework to create ORM DAOs include:
1. Easier testing
2. Common data access exceptions
a. Spring can wrap exceptions from ORM tool, converting them from proprietary (potentially
checked) exceptions to a common runtime DataAccessException hierarchy
3. General resource management
a. Spring application contexts can handle the location and configuration of Hibernate
SessionFactory instances, JPA EntityManagerFactory instances, JDBC DataSource instances,
and other related resources.
b. This makes these values easy to manage and change.
c. Spring offers efficient, easy, and safe handling of persistence resources.
d. Spring makes it easy to create and bind a Session to the current thread transparently, by
exposing a current Session through the Hibernate SessionFactory.
Source : https://docs.spring.io/spring-framework/docs/current/spring-framework-reference/data-access.html
48. SessionFactory
● SessionFactory is an interface
● SessionFactory can be created by providing Configuration object, which will contain all DB
related property details pulled from either hibernate.cfg.xml file or hibernate.properties file.
○ @Autowired
○ protected SessionFactory sessionFactory;
● SessionFactory is a factory for Session objects.
○ Session session = sessionFactory.getCurrentSession()
49. SessionFactory
We can create one SessionFactory implementation per database in any application.
If your application is referring to multiple databases, then you need to create one
SessionFactory per database.
The SessionFactory is a heavyweight object; it is usually created during application start up
and kept for later use. The SessionFactory is a thread safe object and used by all the
threads of an application.
Basically, calling a method "thread-safe" means that even if multiple threads try to access it
simultaneously, nothing bad happens.
50. Session object
Session session = sessionFactory.getCurrentSession()
A Session is used to get a physical connection with a database.
The Session object is lightweight and designed to be instantiated each time an
interaction is needed with the database.
Persistent objects are saved and retrieved through a Session object
54. package hms.config.spring.mvc;
import hms.config.hibernate.AppContext;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class AppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[]{AppContext.class};
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[]{WebMVCConfig.class};
}
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
}
Set up Spring MVC + Hibernate application
55. org.hibernate.query.Query;
The Hibernate Query object is used to retrieve data from database. We can use
either SQL or Hibernate Query Language (HQL).
A Query instance is obtained by calling Session.createQuery().
Query query = session.createQuery(“Query”);
The Query object is used to bind query parameters, limit query results and
execute the query.
56. Hibernate - Criteria Queries
Since Hibernate 5.2, the Hibernate Criteria API is deprecated and new
development is focused on the JPA Criteria API.
It not only enables us to write queries without doing raw SQL, but also gives us
some Object Oriented control over the queries, which is one of the main features
of Hibernate.
57. Hibernate - JPA Annotations
@Entity(name = "course")
public class Course {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String name;
private int duration;
private int cost;
@OneToMany(mappedBy = "course", cascade = CascadeType.ALL)
private List<CourseRequirements> requirements = new ArrayList<>();
//getters and setters
}
