JSFを使用したSpringインジェクション

Question

JSFプロジェクトでspringframeworkを使用してアノテーションを使用してBeanをインジェクトする際に問題がありました。
基本的に私が今までに見つけたすべてのチュートリアルでは、私がすべきことを言っていると思ったのですが、Tomcatに私の戦争を公開し、LoginBeanからloginServiceを使用しようとするとNullPointerExceptionが発生します。何か案は？

私ビーン（短縮）：

package de.homer.server.config.beans; 

import java.io.Serializable; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.context.annotation.Scope; 
import org.springframework.stereotype.Component; 

import de.homer.server.config.user.LoginService; 

@Component 
@Scope("session") 
public class LoginBean implements Serializable { 

     @Autowired 
     LoginService loginService; 

    public final String doLogin() { 
     // try to use loginService here 
     // if I set breakpoint here I can see that loginService is null 
    } 

} 

私のサービス（短縮）：

package de.homer.server.config.user; 

import org.springframework.context.annotation.Scope; 
import org.springframework.stereotype.Component; 

@Component 
public class LoginService { 

} 

私のapplicationContext.xmlを：

私の顔-config.xmlの

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE faces-config PUBLIC

し、それは私のpom.xmlの抜粋を大事場合

 <dependency> 
      <groupId>org.springframework</groupId> 
      <artifactId>spring-web</artifactId> 
      <version>3.1.0.RELEASE</version>

最後のではなく、少なくともログの一部：

Answer 1

、

<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>com.ecs.esr.spring.conf.SpringMainConfig</param-value> 
</context-param> 

が、これは豆のコンストラクタを管理するための追加、web.xmlにこのPARAMを追加し、豆を初期化します。

のfaces-config.xmlの

<?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_0.xsd" 
version="2.0"> 

<application> 
    <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver> 
</application> 

</faces-config> 

豆：

package de.homer.server.config.beans; 

import java.io.Serializable; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.context.annotation.Scope; 
import org.springframework.stereotype.Component; 

import de.homer.server.config.user.LoginService; 

@Component 
@Scope("session") 
@Qualifier("loginBean") 
public class LoginBean implements Serializable { 

    @Autowired 
    LoginService loginService; 

    public final String doLogin() { 
    // try to use loginService here 
    // if I set breakpoint here I can see that loginService is null 
    } 

} 

それはそれは、この設定で動作するのfaces-config.xmlに の廃止予定のバージョンで問題が判明しましたサービス：

package de.homer.server.config.user; 

import org.springframework.stereotype.Service; 

@Service 
public class LoginService { 

} 

感謝の気持ちでいっぱいです！

Answer 2

Autowiredオプションを削除：

サービスとDAO Beanをここで定義します。

@Configuration 
public class ApplicationConfig { 

    @Bean 
    public LoginService loginService() { 
     return new LoginService(); 
    } 
} 

は

@Configuration 
@Import({ PersistenceHibernateConfig.class, SecurityConfig.class, ApplicationConfig.class }) 
public class SpringMainConfig{ 

} 

私は最終的にそれを得た

WebApplicationContext ctx = FacesContextUtils.getWebApplicationContext(FacesContext.getCurrentInstance()); 
loginService = ctx.getBean(LoginService.class);
