java springmvc mybatis mysql

仅供参考

　　java springMvc mybatis mylsq 项目搭建

1.开发环境：

　　window 64、jdk 1.7.0_51、eclipse、tomcat 7

2.jdk安装与环境变量配置

　　http://jingyan.baidu.com/article/6dad5075d1dc40a123e36ea3.html

3.项目搭建

　　jar包: http://pan.baidu.com/s/1cyXn8E

　　jar包中有poi包、pdf包等，后续能用到

　　1）根据自身需求搭建

　　　　　　

　　2)spring-mybatis-config.xml  配置文件，spring 数据库连接、事务等写在一起了，可以分开

    </bean>
</beans>

  　　3) User.java 实体类

package com.springmvc.model;

import java.io.Serializable;

public class User implements Serializable {
    
    private static final long serialVersionUID = -8772180261203847538L;
    
    private Long id;
    private String name;
    private String email;
    private String isEmail;
    private String password;
    private String isDelete;
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public String getIsEmail() {
        return isEmail;
    }
    public void setIsEmail(String isEmail) {
        this.isEmail = isEmail;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public String getIsDelete() {
        return isDelete;
    }
    public void setIsDelete(String isDelete) {
        this.isDelete = isDelete;
    }

}

 　　4)UserDao.java 接口dao

package com.springmvc.dao;

import java.util.List;

import com.springmvc.model.User;

public interface UserDao {
    //简单一个查询
    public List<User> getUser(User user);
}

 　　5)UserService.java 接口service

 　　6)UserServiceImpl.java service接口实现

package com.springmvc.service.impl;

import java.util.List;

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

import com.springmvc.dao.UserDao;
import com.springmvc.model.User;
import com.springmvc.service.UserService;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserDao userDao;

    @Override
    public List<User> getUser(User user) {
        return userDao.getUser(user);
    }

}

　　7)UserEntity.xml 写sql语句文件-简单写一个查询语句，select id 对应到方法名

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" 
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.springmvc.dao.UserDao">
    <parameterMap type="com.springmvc.model.User" id="pa_user">
        <parameter property="id" javaType="Long" jdbcType="NUMERIC"/>
        <parameter property="name"  javaType="String" jdbcType="VARCHAR" />
        <parameter property="email" javaType="String" jdbcType="VARCHAR" />
        <parameter property="isEmail" javaType="String" jdbcType="VARCHAR" />
        <parameter property="password" javaType="String" jdbcType="VARCHAR" />
        <parameter property="isDelete" javaType="String" jdbcType="VARCHAR" />
    </parameterMap>
    <resultMap id="rm_user" type="com.springmvc.model.User">
        <result property="id" column="id" javaType="Long" jdbcType="NUMERIC" />
        <result property="name" column="name" javaType="String" jdbcType="VARCHAR" />
        <result property="email" column="email" javaType="String" jdbcType="VARCHAR" />
        <result property="isEmail" column="isEmail" javaType="String" jdbcType="VARCHAR" />
        <result property="password" column="password" javaType="String" jdbcType="VARCHAR" />
        <result property="isDelete" column="isDelete" javaType="String" jdbcType="VARCHAR" />
    </resultMap>
    <select id="getUser" resultMap="rm_user" parameterType="com.springmvc.model.User">
        select * from user 
        <where>
            1=1 
            <if test="name !=null and name !=''">
                <![CDATA[and name = '${name}']]>
            </if>
            <if test="password !=null and password !=''">
                <![CDATA[and password = '${password}']]>
            </if>
                <![CDATA[and isEmail = '1']]>
                <![CDATA[and isDelete = '0']]>
        </where>
    </select>
</mapper>

　　8)web.xml配置-网上有很多这些配置，不理解的可以在网上查询资料

　　　现在配置的访问后缀：.htm

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>
</web-app>

　　9)dispatcher-servlet.xml  dispatcher对应的配置文件servlet

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <property name="suffix" value=".jsp" />
    </bean>
</beans>

　　10)页面  登入也使用bootstrap，因为可以省去画页面时间。下面的链接下载包括bootstrap、jquery、easyui等

　　　　http://pan.baidu.com/s/1ciIn5W

　　这里是在前台去的绝对路径，先写一个简单的登入功能，等后续开发时，在后台设置

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<jsp:include page="/WEB-INF/util/bootstrap.jsp"></jsp:include>
<script type="text/javascript"  src="<%= basePath %>static/view/js/login.js"> </script>
<title>登入</title>
<style type="text/css">
    .tab-content{
        position:absolute;
        height:200px;
        width:300px;
        margin-top:180px;
        margin-left:50%;
        left:-150px;
    }
    .login-input{
        margin :20px 0px;
        width : 300px;
    }
</style>
</head>
<body>
    <div class="tab-content">
        <ul class="nav nav-tabs">
           <li class="active"><a href="#login" aria-controls="login" role="tab" data-toggle="tab" aria-controls="login">登录</a></li>
           <li><a href="#register" aria-controls="register" role="tab" data-toggle="tab" aria-controls="register">注册</a></li>
       </ul>
        <!-- Tab Log in -->
        <form class="tab-pane fade in active" id="login" onsubmit="return false;">
            <c:if test="${!empty error }">
                <c:out value="${error }"/>
            </c:if>
            <input id="login-email" name="email" class="form-control login-input" placeholder="邮箱">
            <input type="password" name="password" id="login-password" class="form-control login-input" placeholder="密码">
            <div class="checkbox">
            <label class="f-white" style="color:white;">
            <input type="checkbox" id="login-remember"> 记住我
            </label>
            <a class="pull-right" href="javascript:void(0);" style="color:#33B74B;">忘记密码</a>
            </div>
            <button class="btn btn-lg btn-primary btn-block" onclick="loginFunction.loginSubmit();">登录</button>
        </form>
        <!-- Tab Register -->
        <form  class="tab-pane fade" id="register" onsubmit="return false;">
            <input id="login-email" class="form-control login-input" placeholder="邮箱">
            <input type="password" class="form-control login-input" placeholder="密码">

        </form> 
    </div>
    <div id="banner" style="background-image:url(<%= basePath %>static/images/banner-image.jpg);height:575px;width:100%;"> 
    </div>
</body>
</html>

　　11)静态文件  大多数开发都把静态文件放在公共文件中，方便维护、查找

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">

<link href="${basePath}static/bootstrap/css/bootstrap.min.css" rel="stylesheet">

<script type="text/javascript" src="${basePath}static/js/jquery.min.js"></script>
<script type="text/javascript" src="${basePath}static/bootstrap/js/bootstrap.min.js"></script>
<script type="text/javascript">
    var basePath = "${basePath}";
</script>
</head>

　　12)页面对应的js文件 个人习惯单写一个js，也有很多开发者把js写在对应的页面里

　　这里js写的时候有点蒙，因为开发团队有很多人，对应写的页面不同，js可能相似，这样可以避免冲突(loginFunction=页面名称+function)

var loginFunction={
        //登入
        loginSubmit : function(){
            var email = $("#login-email").val();//邮箱
            var password = $("#login-password").val();//密码
            if(email =="") {
                alert("请输入邮箱");
                return;
            }
            if(password =="") {
                alert("请输入密码");
                return;
            }
            //$("#login").attr("action",basePath+"index.htm");
            //$("#login").submit();
            $.ajax({
                url:basePath+"101/loginCheck.htm",
                type:"post",
                data:{email : email,password:password},//密码得加密
                dataType:"json",
                success: function(data){
                    if(data.status == "success"){
                        window.location.href = basePath+"101/index.htm";
                    }else{
                        alert("用户名或密码错误");
                    }
                },  
                error : function(data) {
                    
                }
            });
            
        }
};
$(function(){
});

　　13)action-简单写了一个验证功能，正常情况密码加密、设置session等，这些后续开发

package com.springmvc.action;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import com.springmvc.model.User;
import com.springmvc.service.UserService;

@Controller
@RequestMapping(value = "/101")
public class IndexAction {

    @Autowired
    private UserService userService;

    /**
     * 首页
     * 
     * @return
     */
    @RequestMapping(value = "/index.htm")
    public String index() {
        return "index";
    }

    /**
     * 登入页面
     * 
     * @return
     */
    @RequestMapping(value = "/login.htm")
    public String login() {
        return "login";
    }

    /**
     * 登入验证
     * 
     * @return
     */
    @RequestMapping(value = "/loginCheck.htm", method = RequestMethod.POST)
    @ResponseBody
    public Map<String, Object> loginCheck(User user) {
        List<User> list = userService.getUser(user);
        Map<String, Object> map = new HashMap<String, Object>();
        if (list != null && list.size() > 0) {
            map.put("status", "success");
            map.put("message", "验证成功");
        }
        return map;
    }

}
