java web开发入门十一（idea maven mybatis自动代码生成）基于intellig idea

6.idea maven mybatis逆向工程（代码生成器）

 1.配置pom.xml

在plugins标签下添加mybatis-generator-maven-plugin

 <plugin>
          <groupId>org.mybatis.generatorgroupId>
          <artifactId>mybatis-generator-maven-pluginartifactId>
          <version>1.3.2version>
          <configuration>
            <verbose>trueverbose>
            <overwrite>trueoverwrite>
          configuration>
        plugin>

2.配置generatorConfig.xml

在resources文件夹下新建generatorConfig.xml

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

<generatorConfiguration>
    
    <properties resource="generator.properties">properties>

    
    <classPathEntry location="${jdbc.driverLocation}"/>

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

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

        
        <jdbcConnection
                driverClass="${jdbc.driverClass}"
                connectionURL="${jdbc.connectionURL}"
                userId="${jdbc.userId}"
                password="${jdbc.password}">
        jdbcConnection>


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


        
        <javaModelGenerator targetPackage="com.eggtwo.entity"
                            targetProject="src/main/java">

            
            <property name="enableSubPackages" value="false"/>
            
            <property name="constructorBased" value="false"/>
            
            
            <property name="trimStrings" value="true"/>
            
            <property name="immutable" value="false"/>
        javaModelGenerator>

        
        <sqlMapGenerator targetPackage="com.eggtwo.entity"
                         targetProject="src/main/java">
            <property name="enableSubPackages" value="false"/>
        sqlMapGenerator>

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


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

    context>
generatorConfiguration>

里面引用了数据库配置文件：

在resources文件夹下新建generator.properties

## mysql驱动文件对应的路径，不要和项目引用的mysql驱动jar位置一致
jdbc.driverLocation=D:\\Java\\jars\\mysql-connector-java-5.1.7-bin.jar
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.connectionURL=jdbc:mysql://127.0.0.1:3306/test?characterEncoding=utf8&useSSL=false
jdbc.userId=root
jdbc.password=123456

3.配置基于maven的mybatis generate命令

mybatis-generator:generate -e

 4.运行生成命令：

选择mybatis-generate，然后点击运行
