spring+struts 使用注解配置(简单的登陆模块)

1. 首先配xml,并且导入jar包.（因为就是开始，所以只导入核心的包）.

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 

    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <context-param>

        <param-name>contextConfigLocation</param-name>

        <param-value>classpath:applicationContext.xml</param-value>

    </context-param>

    <listener>

        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

    </listener>

    <filter>

        <filter-name>struts2</filter-name>

        <filter-class>

            org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

    </filter>

    <filter-mapping>

        <filter-name>struts2</filter-name>

        <url-pattern>*.action</url-pattern>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

    <welcome-file-list>

        <welcome-file>Public/login.jsp</welcome-file>

    </welcome-file-list>

</web-app>

2第二部开始为工程建包，为了省事就不都弄了，不然应该有一个page包和symbol包，service也应该先建接口。

3配置applicationContext.xml和struts.xml

<?xml version="1.0" encoding="UTF-8"?>

            <result name="fail">fail.jsp</result>

        </action>

    </package>

</struts>

4为自己已经写好的程序添加注解

<1>首先是dao的实现类

import java.sql.ResultSet;

import java.sql.SQLException;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.jdbc.core.JdbcTemplate;

import org.springframework.jdbc.core.RowMapper;

import org.springframework.stereotype.Component;

import org.springframework.stereotype.Repository;



import com.sky.bean.User;

import com.sky.dao.LoginDao;



/*

 * dao层主要做数据库的增删改查

 * 对数据库的操作通常都在dao中完成

 */

@Repository

public class Loginimpl implements LoginDao {

    @Autowired

    private JdbcTemplate jdbcTemplate;



    User user2 = null;



    public boolean findByLoginService(User user) {

        int count = this.jdbcTemplate

                .queryForInt("select count(*) from user where name='"

                        + user.getName() + "'");

        if (count <= 0) {

            return false;

        }

        // 判断用户是否存在

        System.out.println(user.getName() + "  " + user.getPass());

        user2 = (User) this.jdbcTemplate.queryForObject(

                "select * from user where name='" + user.getName() + "'",

                new UserResult());

        System.out.println(user2.getName() + "  " + user2.getPass());

        // 登录名存在的话，判断密码是否正确

        if (user.getName().equals(user2.getName())

                && user.getPass().equals(user2.getPass())) {

            System.out.println("ok");

            System.out.println(user.getName() + "  " + user.getPass());

            return true;

        } else {

            return false;

        }

    }



    /**

     * 

     * @ClassName: UserResult

     * @Description: TODO(为user服务的RowMapper)

     * @author A18ccms a18ccms_gmail_com

     * @date 2014-11-19 下午09:05:09

     * 

     */

    public class UserResult implements RowMapper<User> {

        public User mapRow(ResultSet rs, int id) throws SQLException {

            User groupPageBean = new User();

            User user = new User();

            user.setName(rs.getString("name"));

            user.setPass(rs.getString("pass"));

            return user;

        }



    }

}

<2>然后是service的实现类package com.sky.service;

import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.sky.bean.User; import com.sky.dao.LoginDao; /** * * @ClassName: LoginService * @Description: TODO(我是这样理解的，使用dao的方法实现服务的类) * @author A18ccms a18ccms_gmail_com * @date 2014-11-20 下午02:43:14 * */ @Service public class LoginService { @Autowired public LoginDao loginimpl ; 

public boolean dovalidate(User user)
{ 
System.out.println(

loginimpl.findByLoginService(user)+"----"); 

return

loginimpl.findByLoginService(user); } 

}

<3>最后是action类

import java.io.IOException;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import com.opensymphony.xwork2.ModelDriven;

import com.sky.bean.User;

import com.sky.service.LoginService;



@Controller

public class LoginAction implements ModelDriven<User> {

    private User user = new User();

    @Autowired

    public LoginService loginService;



    public String dologin() throws IOException {

        boolean flag = loginService.dovalidate(user);

        if (flag) {

            return "success";

        } else {

            return "fail";

        }

    }



    public User getModel() {

        // TODO Auto-generated method stub

        return user;

    }



}

5再来就是前台页面了。
