最近在做一個(gè)需要JSF和Spring整合的項(xiàng)目，之前不知道如何在后臺(tái)管理Bean獲取被Spring管理的業(yè)務(wù)類對(duì)象，現(xiàn)在解決了，可以跑起來(lái)了！

InfoBean.java
假如InfoBean中需要使用業(yè)務(wù)類UserService的方法，而UserService交由Spring管理(id="userService")，InfoBean可以這樣寫：
package com.jam.managedbeans;
import java.util.Map;
import javax.faces.context.ExternalContext;
import javax.faces.context.FacesContext;
import org.springframework.context.ApplicationContext;
import org.springframework.web.jsf.FacesContextUtils;
import com.jam.hibeinate.po.Bloguser;
import com.jam.service.UserService;
/**
* @author Jam Chan
*
*/
public final class InfoBean extends Object {
/**
* 用戶名
*/
private String userName;
/**
* 業(yè)務(wù)類
*/
private UserService userService;
/**
* 密碼
*/
private String password;
/**
* 登陸驗(yàn)證
*
* @return
*/
public String loginValidate() {
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext extnContext = facesContext.getExternalContext();
// POJO類
Bloguser objUser = new Bloguser();
objUser.setUsername(getUserName());
objUser.setPassword(getPassword1());
// 從Spring中獲取需要的業(yè)務(wù)類UserService，我就是在這里被卡住，終于OK了
ApplicationContext appContext = FacesContextUtils.getWebApplicationContext(facesContext);
userService = (UserService) appContext.getBean("userService");
// 驗(yàn)證用戶
boolean result = userService.loginValidate(objUser);
// 獲取SessionMap
Map sessionMap = extnContext.getSessionMap();
if (result) { // 登陸成功
/* 把用戶名設(shè)置在Session中 */
sessionMap.put("userName", getUserName());
return "success";
} else { // 登錄失敗
/* 清空session */
if (sessionMap.containsKey("userName")) {
sessionMap.remove("userName");
}
return "failed";
}
}
// setter getter省略
暫時(shí)寫到這，可能還要查漏補(bǔ)缺，發(fā)現(xiàn)問(wèn)題繼續(xù)加上！
