Trouble spring injection in JSF2 Bean with annotation - spring

Question

I have a trouble with Spring Injection in my web project. I must use in a JSF2 bean.
Show my work :
SgbdServiceImpl.java (shorted)
#Service
public class SgbdServiceImpl implements SgbdService {
#Override
public List<Sgbd> findAll() {
return null;
}
#Override
public Sgbd findOneByName(String nom) {
return null;
}
}
SgbdBean
#Component
#SessionScoped
#ManagedBean(name="sgbd")
public class SgbdBean {
#Autowired
SgbdService sgbdService;
public List<Sgbd> findAll(){
return sgbdService.findAll();
}
}
I put this configuration in the file : web.xml
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
<listener-class>
org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>
This Spring configuration in applicationContext.xml :
<beans xmlns="http://www.springframework.org/schema/beans"
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-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<context:annotation-config />
<context:component-scan base-package="main.java.com.erdf.agir.services" />
</beans>
And, in faces-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-facesconfig_2_1.xsd"
version="2.1">
<application>
<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
</application>
</faces-config>
I would like call findAll() from service but i obtain all time nullPointerException from sgbdService attribut (Autowired failled ?)
I follow this example : http://rsuna.blogspot.fr/2013/05/how-to-integrate-jsf-20-with-spring-3.html
Did I miss anything ?

Answer 1

You have a context clash; using both #Component and #ManagedBean on the same class definition put your bean in two contexts: JSF and Spring's. Let's now establish that #Autowired will not work in the JSF context.
You could get rid of the spring-based annotations and go with a JSF-centric setup. What this will leave with you with
#SessionScoped
#ManagedBean(name="sgbd")
public class SgbdBean {
#ManagedProperty(value="#{sgbdServiceImpl}")
SgbdService sgbdService;
public List<Sgbd> findAll(){
return sgbdService.findAll();
}
}
You could stick with a strictly spring-centric approach with
#Component
public class SgbdBean {
#Autowired
SgbdService sgbdService;
public List<Sgbd> findAll(){
return sgbdService.findAll();
}
}

Things I have encountered
1) Better to mention service name with annotation - #Service("sgbdService")
2) Rather than #ManagedBean it is better to use #Qualifier annotation -
#Qualifier("sgbdBean")
3) Add <context:sping-configured/> entry to applicationContext.xml file
4) Try with top level component scan entry as
<context:component-scan base-package="main.java.com.erdf" />
