pom.xml

网上有很多用junit教你搭的，虽然都能跑，但是如果要实际运行和前台交互，那样是不行的，还要导入我所导入的包。

 

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:web="http://xmlns.jcp.org/xml/ns/javaee">
 3     <display-name>Archetype Created Web Application</display-name>
 4     <filter>
 5         <filter-name>struts2</filter-name>
 6         <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
 7         </filter-class>
 8     </filter>
 9     <filter-mapping>
10         <filter-name>struts2</filter-name>
11         <url-pattern>/*</url-pattern>
12     </filter-mapping>
13     <listener>
14         <listener-class>org.springframework.web.context.ContextLoaderListener
15         </listener-class>
16     </listener>
17     <context-param>
18         <param-name>contextConfigLocation</param-name>
19         <param-value>classpath:applicationContext.xml</param-value>
20     </context-param>
21 </web-app>

 

 web.xml

则多了sprig的配置，留意<context-param>，自带的web.xml会报错说版本不对，只要把开头的那一坨玩意去掉即可。

其他就是在resource文件夹下的配置文件

 

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
 4     xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
 5     xsi:schemaLocation="

10      http://www.springframework.org/schema/aop 
11      http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
12      http://www.springframework.org/schema/context
13      http://www.springframework.org/schema/context/spring-context-3.0.xsd">
14     <bean id="userDao" class="com.dao.impl.UserDao"></bean>
15     <bean id="userService" class="com.service.impl.UserService">
16         <property name="userDao" ref="userDao"></property>
17     </bean>
18     <bean id="userAction" class="com.action.UserAction">
19         <property name="userService" ref="userService"></property>
20     </bean>
21 </beans>

 applicationcontext.xml 使用的是依赖注入，这个方法在初学spring的时候，对spring有很好的理解，层层递进，关系明了，当然实际应用通常用注解注入，但是如果我那样写的话，就看不透它的运行轨迹了。

java代码

 1 package com.service.impl;
 2 
 3 import com.dao.IUserDao;
 4 import com.service.IUserService;
 5 
 6 public class UserService implements IUserService {
 7     private IUserDao userDao;
 8 
 9     public void setUserDao(IUserDao userDao) {
10         this.userDao = userDao;
11     }
12 
13     public void add() {
14         System.out.println("UserService.add()");
15         userDao.add();
16     }
17 
18 }

 

1 package com.service;
2 
3 public interface IUserService {
4     public void add();
5 }

 

 1 package com.dao.impl;
 2 
 3 import com.dao.IUserDao;
 4 
 5 public class UserDao implements IUserDao{
 6 
 7     public void add() {
 8         System.out.println("UserDao.add()");
 9     }
10 }

 

1 package com.dao;
2 
3 public interface IUserDao {
4     public void add();
5 }

 

package com.action;

import com.service.IUserService;

public class UserAction {
    private String name;
    private String pwd;
    private IUserService userService;

    public String add() {
        System.out.println("name--" + this.getName());
        System.out.println("pwd---" + this.getPwd());
        userService.add();
        return "success";
    }

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPwd() {
        return pwd;
    }

    public void setPwd(String pwd) {
        this.pwd = pwd;
    }
}

 

留意是用接口来实现方法的。
