MyBatis-generator与generatorConfig.xml结合逆向生成实体、mapper和dao层

MyBatis-generator与generatorConfig.xml结合逆向生成实体、mapper和dao层

结合上篇博客，今天分享下个人的心得，刚接触ssm时知道有逆向生成这回事，于是就在网上各种搜。

这篇说这个嘛很简单，什么dos命令。那篇说怎么怎么样，最后什么也没学到。。。。

好了，言归正传。

一.准备mybatis-generator jar包

在pom.xml中配置获取mybatis-generator jar包

以上是我用的配置文件，导入后获得下图Jar包

二.获取数据库连接

三.重点是generatorConfig.xml文件

xml version="1.0" encoding="UTF-8"?>
 generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>
    <properties resource="jdbc.properties">properties>
    
    
    <classPathEntry location="C:\Users\user\.m2\repository\mysql\mysql-connector-java\5.1.6\mysql-connector-java-5.1.6.jar"/>

    <context id="default" targetRuntime="MyBatis3">

        
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property name="suppressAllComments" value="true"/>
        commentGenerator>

        
        <jdbcConnection
                driverClass="${driver}"
                connectionURL="${url}"
                userId="${username}"
                password="${password}">
        jdbcConnection>


        
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        javaTypeResolver>


        
        
        <javaModelGenerator targetPackage="com.mmall.pojo" targetProject="./src/main/java">
            
            <property name="enableSubPackages" value="false"/>
            
            <property name="constructorBased" value="true"/>
            
            <property name="trimStrings" value="true"/>
            
            <property name="immutable" value="false"/>
        javaModelGenerator>

        
        
        <sqlMapGenerator targetPackage="mappers" targetProject="./src/main/resources">
            <property name="enableSubPackages" value="false"/>
        sqlMapGenerator>

        

        
        
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.mmall.dao" targetProject="./src/main/java">
            
            <property name="enableSubPackages" value="false" />
        javaClientGenerator>



        <table tableName="t_user" domainObjectName="t_user" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">table>


        
    context>
generatorConfiguration>

注意三点：

1.Mysql Jar包引用路径

2.包名只需命名就可自动生成，不用手动创建

3.tableName与表名相对应
