I am trying to use the bean created in the spring Container in the JSF ManagedBean using @ManagedProperty annotation.But I am getting null pointer when using that bean.Once I start my server I can see my beans are created Here
Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@9d532ae: defining beans [org.springframework.context.annotation.internalConfigurationAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor,org.springframework.context.annotation.internalCommonAnnotationProcessor,org.springframework.context.annotation.internalPersistenceAnnotationProcessor,userBean,userService];
HomepageBean.java
package come.test.backingbean
@ManagedBean
@sessionScoped
public Class HomepageBean{
@ManagedProperty(value="#{userBean}")
private UserBean userBean;// getters and setters
public String doLogin() {
String url = "login.xhtml";
LoginBean manager = new LoginBean(); // This bean has a condition which check for Username and password entered by user.
if (manager.auth(username, password)) {
isLoggedIn = true;
url = "homepage";
String username=sample;
userBean.getUserInfo(username);
} else {
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage(username, new FacesMessage(
"Invalid Username and or Password"));
}
return url;
}
UserBean.java
package com.test.mypackage
@Component
Public Class UserBean{
@Autowired
private UserService userServie // getters and setters.
public void getUserInfo(String userId){
userService.findByUserId(userId)
}
}
}
UserService.java
package com.test.service;
public interface UserService {
public void save(User User);
public void update(User user);
public void delete(User user);
public User findByUserId(String userId);
}
I can see when my server started the bean I am trying to use is pre-instantiated.I am defining my applicationContext.xml in web.xml as a Context-param. And I am defining all the beans in my Spring.xml like this
spring.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:annotation-config />
<context:component-scan base-package="com.test" />
<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
</beans>
which is in my class path and importing that as a resource in applicationContext.xml.
applicationContext.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:security="http://www.springframework.org/schema/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<import resource="classpath:database/DataSource.xml" />
<import resource="classpath:database/Hibernate.xml" />
<import resource="classpath:config/Spring.xml" />
</beans>
my faces-confi.xml
<application>
<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
<resource-bundle>
<base-name>com.test.boundles.messages</base-name>
<var>msg</var>
</resource-bundle>
</application>
Any problem with my approach.
