使用注解的方式，配置文件最少可以精简到三个，web.xml、applicationContext.xml和struts.xml。Hibernate可以完全交给Spring来管理，这样连hibernate.cfg.xml也省了。下面就一起看看这些基本的配置吧！

 

web.xml

 
        
      
       Archetype Created Web Application
         
         
           
       
        contextConfigLocation
            
       
        classpath:applicationContext.xml
          
         
         
           
       
        struts
            
       
        org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
          
         
           
       
        struts
            
       
        /*
          
         
           
       
        org.springframework.web.context.ContextLoaderListener
          
       
     

　　

 

web.xml中包含了Spring和struts的基本配置，自动扫描Action的配置就是告诉tomcat，我要使用注解来配置struts。

 

applicationContext.xml

      
          
           
           
               
                
                
                
            
           
           
           
           
               
                
                    
                         
                          
         
          org.hibernate.dialect.Oracle10gDialect
                          
                          
         
          update
                          
                          
         
          true
                          
         
          true
                          
         
          org.springframework.orm.hibernate5.SpringSessionContext
                      
                 
                
                
            
           
           
               
            
           
           
       
     

　　User实体

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层实现一个增加的方法

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;@Repositorypublic class UserDao {	@Resource(name="sessionFactory") 	private SessionFactory sessionFactory;		public void addUser(User user ) {		Session session = sessionFactory.getCurrentSession();		session.save(user);	}}

　　service层

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@Transactionalpublic class UserManager {	@Resource	UserDao userDao;		public void addUser(User user) {		userDao.addUser(user);	}	}

　　action层

UserAction通过注解配置Action的名字和返回的页面，通过@Resource活动Spring注入的UserManager对象，然后进行相应的操作。Action里还有@Namespace、@InterceptorRef等很多注解可以用，根据自己需要选择吧。

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;    }        }

　　页面jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
