Spring+SpringMVC+Mybatis+Shiro框架整合-yellowcong
来源：互联网 发布：淘宝商城女童装秋装 编辑：程序博客网 时间：2024/06/05 08:38
说实话，Spring+Spring+Mybatis整合过程中，我觉得最坑的一点是1、Maven的项目聚合与继承,编译的jdk版本不一致
2、还有一个问题是项目是WEb2.5，Maven的生成框架是WEB2.3的问题，Maven之Cannot change version of project facet Dynamic Web Module to 2.5.-yellowcong
3、单独点击Junit单元测试,找不到配置文件的问题（这个是父类Junit 的scope的设置为Test，导致子类打死都不能 spring.xml和类，发现maven项目目录下的test-classes连个 类都没有，问题就处在scope上）
4、Mybatis的坑，返回的集合类型数据，多条集合类型是ResultMap，单条model是ResultType
项目地址：https://gitee.com/yellowcong/shior-dmeo.git
项目目录结构
这个目录有一个parent（普通j2ee的项目），用于父类的pom.xml配置文件，同时打包的时候，直接使用父类项目打包，这样也挺方便的，分包的策略，可以快速定位错误位置
web目录，是所有的目录操作，没有将web目录拆分成 util,dao,service这三个子包，只做了一个web的
parent项目pom.xml
parent项目是一个简单的j2ee项目，没有web的类容
父类项目相当于将整个项目的环境都配置了，这样子类项目自需要继承父类项目，就可以完成环境的配置

子类web的pom配置，没有太多东西，只需要继承父类就可以了， 同时也要和父类一样将packing的方式改为pom，才可以

web配置中主要有 jdbc,mybatis,shiro的配置操作
jdbc配置
jdbc.properties数据库的连接配置，我这个是本地的数据库，使用的是阿里的druid,常用的数据库连接池有dbcp,c3p0,druid

mybatis配置文件，配置了事务操作

用户对象操作，
package com.yellowcong.dao;import java.util.List;import com.yellowcong.model.User;/** * 创建日期:2017年9月23日 <br/> * 创建用户:yellowcong <br/> * 功能描述:用户的操作类 */public interface UserMapper { /** * * 创建日期:2017年9月23日<br/> * 创建用户:yellowcong<br/> * 功能描述:来获取用户大于 这个 age的人 * @param age * @return */ List<User> list(); Integer getCount(); /** * 用户登录操作 * 创建日期:2017年9月23日<br/> * 创建用户:yellowcong<br/> * 功能描述: * @param username 用户名 * @return */ User login(String username);}UserMapper.xml
写这个UserMapper的时候，一定要注意
1、namespace 是否和类名对应 上了
2、resultMap 返回填的是 id属性(User)
3、resultType 填写的才是type属性（com.yellowcong.model.User）
<?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.yellowcong.dao.UserMapper" > <!-- 配置映射字段 --> <resultMap type="com.yellowcong.model.User" id="User"> <result property="id" column="id"/> <result property="age" column="age"/> <result property="nickname" column="nick_name"/> <result property="password" column="password"/> <result property="username" column="user_name"/> </resultMap> <!-- 获取用户列表 resultMap 这个是返回的是ResultMap的id， --> <select id="list" resultMap="User"> SELECT * FROM YELLOWCONG_USERS </select> <!-- 用户登录操作 --> <!-- resultType 返回的是 type --> <select id="login" parameterType="java.lang.String" resultType="com.yellowcong.model.User"> SELECT USER FROM YELLOWCONG_USERS WHERE user_name = #{username} </select> <!-- 查询用户条数 --> <select id="getCount" resultType="java.lang.Integer"> SELECT COUNT(id) FROM YELLOWCONG_USERS </select></mapper>余下的，就没有必要贴了，就是实体类了，我把项目丢在码云上，大家可以下载查看
