jsf使用spring注入的bean

jsf的后台bean中使用spring定义的service，需要使用@ManagedProperty，并且要具有该属性的getter/setter方法。

package cn.catr.lm.idc.controller;

import cn.catr.lm.idc.service.UserService;
import java.io.Serializable;
import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.bean.ViewScoped;

@ManagedBean(name = "testBean")
@ViewScoped
public class TestController implements Serializable{

    @ManagedProperty(value = "#{userService}")
    private UserService userService;

    private String user;

    @PostConstruct
    private void init() {
        user = userService.save();
        System.out.println("ok.");
    }

    public String getUser() {
        return user;
    }

    public UserService getUserService() {
        return userService;
    }

    public void setUserService(UserService userService) {
        this.userService = userService;
    }

}
