# maven配置mybatis-generator自动生成mapper.xml #

> 涉及表较多的情况下，快速生成mapper接口、mapper.xml文件、pojo实体类  
> 会用到mybatis-generator技术，记录一下供以后搭建框架参考。

## pom引入插件 ##

<plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.5</version>
        <configuration>
            
            <configurationFile>src/main/resources/generator/generatorConfig.xml</configurationFile>
            <overwrite>true</overwrite>
            <verbose>true</verbose>
        </configuration>

        </dependencies>
    </plugin>

## 编写generatorConfig.xml文件 ##

<?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="application.properties"/>
        <context id="xxxxx"  targetRuntime="MyBatis3">
            <commentGenerator>
                <property name="suppressDate" value="true"/>
                <property name="suppressAllComments" value="true"/>
            </commentGenerator>
            
            
            <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://xxx" userId="xxx" password="xxx">
            </jdbcConnection>
            <javaTypeResolver>
                <property name="forceBigDecimals" value="false"/>
            </javaTypeResolver>
    
            
            <javaModelGenerator targetPackage="com.xxx.xxx.domain" targetProject="src/main/java">
                <property name="enableSubPackages" value="true"/>
                <property name="trimStrings" value="true"/>
            </javaModelGenerator>
            
            
            <sqlMapGenerator targetPackage="mapper.xxx" targetProject="src/main/resources">
                <property name="enableSubPackages" value="true"/>
            </sqlMapGenerator>
            
            
            <javaClientGenerator type="XMLMAPPER" targetPackage="com.xxx.xxx.mapper" targetProject="src/main/java">
                <property name="enableSubPackages" value="true"/>
            </javaClientGenerator>
            
            
            <table tableName="xxxx"  enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"	enableSelectByExample="false" selectByExampleQueryId="false"></table>
        </context>
    
    </generatorConfiguration>

## 执行mybatis generator命令 ##

> 如下所示操作，或者使用命令：mvn mybatis-generator:generate
