How to use lazy loading in Spring MVC - java

How to use lazy loading in Spring MVC? I'm using eager at this moment, but this makes my app works slowler.
This is part of my domain:
#ManyToMany(fetch = FetchType.EAGER)
#JoinTable(name = "NEWS_TAG", joinColumns = #JoinColumn(name = "NEWS_ID"), inverseJoinColumns = #JoinColumn(name = "TAG_ID"))
private List<Tags> tags = new ArrayList<Tags>();
public List<Tags> getTags() {
return this.tags;
}
And dao:
public List<News> getSomeNews(long b, long hm) {
List<News> news = (List<News>) sessionFactory
.getCurrentSession()
.createQuery(
"from News WHERE title!='About' ORDER BY publish_time")
.setMaxResults((int) hm).setFirstResult((int) b).list();
return news;
}

What I have to do to solve my problem?

You can use OpenSessionInViewFilter to prevent hibernate session get closed. Add this to web.xml:
<filter>
<filter-name>hibernateFilterChain</filter-name>
<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>hibernateFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
#see read more here: OpenSessionInViewFilter
And remove fetch = FetchType.EAGER. #ManyToMany is LAZY by default.

Change your annotation to (fetch = FetchType.LAZY). Be aware that if you're passing the result to some code outside the transaction (such as a view template), you might encounter errors if associated objects needed by the external code haven't already been loaded.

I get the error
HTTP Status 500 - org.apache.jasper.JasperException: org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread
What should I do to make the second variant working?
You have component-scanning in mvc config file as well as data config file:
Inside /WEB-INF/spring-mvc-servlet.xml:
<context:component-scan base-package="com.hihoall"/>
Inside /WEB-INF/appconfig-root.xml
<context:component-scan base-package="com.hihoall.*"/>
Since they are scanning the same packages, then the beans are loaded 2 times here, once by mvc config & another by root config. So they are stored in Web Application Context and another in Root Application Context.
Now the transaction management beans are defined in root config file (because you are importing /WEB-INF/appconfig-data.xml in root config file).
This is causing issue with your application, the controller classes might got the beans from web application context which do not have an idea about transaction management, so when you are doing DML operations it is failing with that error.

Spring application AJAX call after login returns 404 not found

I ahve a spring application where an ajax call after login dosen't work.
I made the ajax function as below in CHrome dev tools snippets.
var today = new Date();
var month=today.getMonth();
var name="testuser";
$(document).ready(function(){
$.ajax({
type: "GET",
url: "ajax/getStmt",
data: "name="+name+"&month="+month,
success: function(msg){
alert( "Data Saved: " + msg );
},
error: function(msg){
alert("there was an error \n"+msg);
}
});
});
controller:
package com.cardholder.controller.ajax;
#Controller
public class StatementAjax {
#Autowired
public UserDao userDao;
//initialise logger, dao
#RequestMapping(value = "/ajax/getMonths", method = RequestMethod.GET)
public String getMonths(){
//get user from session
//get user token from session
/*UserStatement availableStmts = new UserStatement();
availableStmts.setAvailableStatements(userDao.getUserStatementMonths(user.getUser_token()));*/
return "months";
}
#RequestMapping(value = "/ajax/getStmt", method = RequestMethod.GET)
public String getStatement(#RequestParam(required = true) String name, #RequestParam(required = true) String month){
System.out.println(name+", "+month);
//get user from session
//get user token from session
/*UserStatement availableStmts = new UserStatement();
availableStmts.setAvailableStatements(userDao.getUserStatementMonths(user.getUser_token()));
ArrayList<UserStatement> s = (ArrayList<UserStatement>) userDao.getUserSelectedStatement(user.getUser_token(), 07, 2015);*/
return "statements";
}

As far as i know the request dosent even enter the application context even if the URL its trying to access is right.
i have a debug point in the dispatcher servlet's do dispatch method which should have been the first place to be reached before any interceptors, controllers etc. i dont see any thread pausing there.

Based on the above config Spring's dispatcher will be consulted, only if the incoming URL has some path info. e.g. login.htm, something.xx. However, if the url has no path info, like /getStmt, the dispatcher will not receive the request.
You can either change your ajax end point to some thing like /getStmt.ajax. Or add /as a url pattern in the web xml (this could have other implications, based on how other resources are served in your project).
If you are currently serving pages through xxxx.htm convention, I would recommend using xxxx.ajax convention for ajax requests.
You might also want to look at this answer : No mapping found for HTTP request with URI Spring MVC
Hope this helps.

Add this entries to your dispatcher servlet,
<bean id="utenteDAO" class="path" />
<bean id="utenteDAOImplementation class" class="path" />
it is throwing error because you have not autowired the dependencies
EDIT:
try defining the session factory,
#Autowired
#Qualifier("sessionFactory")
public void seSessionFactory(SessionFactory sessionFactory) {
this.setSessionFactory(sessionFactory);
}
change the location of the project folder and set system path and path properties accordingly .It works in our case.But we are unable to find the exact reason.

This is the servlet file in which the annotaions are used to cal to particular controllers.
This servlet contains the beans through which the request is redirected to particular controllers.
But the main problem is jsp file is not working only...
What can I do in web.xml so that it allows me to access the jsp file on server side??
Is that the problem with Spring framework or the web.xml file is missing something???
I assume the jsp you are accessing is outside of your WEB-INF folder. In such cases, use <mvc:resources mapping="/static/**" location="/" /> in your seekersworkroom-servlet.xml; and access the jsp using url http://yourdomain/static/yourjspname.jsp.
Also, you may not need to protect your static resources; So, use
<http pattern="/static/**" security="none" xmlns="http://www.springframework.org/schema/security"/> in your spring security configuration file

OpenSessionInViewFilter doesnt work in a JSF+Spring+Hibernate application

I want to use OpenSessionInViewFilter in my JSF 2.1+Spring 3.1+Hibernate 3.6.6 project
in order to get rid of the .LazyInitializationException.
Although i declare the filter in web.xml i keep getting ;
org.hibernate.LazyInitializationException: failed to lazily initialize
a collection of role: pts.entity.Invention.inventors, no
session or session was closed

I use spring managed(HibernateTemplate) hibernate daos for db operations.Thanks for the help.
You just have to be sure that you are not redirecting between JSF view for example:
In this view your Open Session in vew Filter will work:
<navigation-rule>
<from-view-id>start.xhtml</from-view-id>
<navigation-case>
<from-outcome>page1</from-outcome>
<to-view-id>page1.xhtml</to-view-id>
</navigation-case>
</navigation-rule>
and if you modify this example this way:
<navigation-rule>
<from-view-id>start.xhtml</from-view-id>
<navigation-case>
<from-outcome>page1</from-outcome>
<to-view-id>page1.xhtml</to-view-id>
<redirect />
</navigation-case>
</navigation-rule>
Your Filter will bnot help you because you are redirecting and this is completely new request and your original Hibernate session is already closed.
Inspired by this post:
OpenSessionInViewFilter +Redirect in JSF
When does it fail? I can see that you use Spring Security and have springSecurityFilterChain defined in you web.xml. And would assume that filter loads user from database and user has lazy collection that is accessed later, when Hibernate session created during authentication is propably closed, before OpenSessionInView filter starts executing.
Remember that filter-mapping order makes sense, filter executed in the order of their filter mappings are declared. I would try reorder them first.
