使用註解的方式，配置文件最少可以精簡到三個，web.xml、applicationContext.xml和struts.xml。Hibernate可以完全交給Spring來管理，這樣連hibernate.cfg.xml也省了。下面就一起看看這些基本的配置吧！
web.xml
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name>Archetype Created Web Application</display-name><!--Spring配置
1.上下文 識別applicationContext.xml
2.監聽器 在Tomcat容器啟動的時候，幫我創建Spring容器，並且放入application中-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!--Struts2配置 核心過濾器 --><filter>
<filter-name>struts</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts</filter-name>
<url-pattern>/*</url-pattern></filter-mapping>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>
web.xml中包含了Spring和struts的基本配置，自動掃描Action的配置就是告訴tomcat，我要使用註解來配置struts。
applicationContext.xml

User實體
package com.tgb.ssh.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity(name="t_user")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String name;
private String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
dao層實現一個增加的方法
package com.tgb.ssh.dao;
import javax.annotation.Resource;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.orm.hibernate4.HibernateTemplate;
import org.springframework.stereotype.Repository;
import com.tgb.ssh.model.User;
@Repository
public class UserDao {
@Resource(name="sessionFactory")
private SessionFactory sessionFactory;
public void addUser(User user ) {
Session session = sessionFactory.getCurrentSession();
session.save(user);
}
}
service層
package com.tgb.ssh.service;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.tgb.ssh.dao.UserDao;
import com.tgb.ssh.model.User;
@Service
@Transactional
public class UserManager {
@Resource
UserDao userDao;
public void addUser(User user) {
userDao.addUser(user);
}
}
action層
UserAction通過註解配置Action的名字和返回的頁面，通過@Resource活動Spring註入的UserManager對象，然後進行相應的操作。Action裏還有@Namespace、@InterceptorRef等很多註解可以用，根據自己需要選擇吧。
package com.tgb.ssh.action;
import javax.annotation.Resource;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.convention.annotation.Results;
import com.opensymphony.xwork2.ActionSupport;
import com.tgb.ssh.model.User;
import com.tgb.ssh.service.UserManager;
@Results( { @Result(name="success",location="/success.jsp"),
@Result(name="failure",location="/failure.jsp") })
public class UserAction extends ActionSupport {
@Resource
private UserManager userManager;
private User user;
@Action(value="addUser")
public String addUser() {
try {
userManager.addUser(user);
} catch (Exception e) {
e.printStackTrace();
return "failure";
}
return "success";
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
頁面jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
