mybatis generator

1.在pom.xml 中导入

<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.7</version>
</plugin>

 

2.在resources 目录下 添加一个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>
    <classPathEntry location="C:\Users\10105\.m2\repository\mysql\mysql-connector-java\8.0.28\mysql-connector-java-8.0.28.jar" />

    <context id="DB2Tables" targetRuntime="MyBatis3">
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://127.0.0.1:3306/mall?characterEncoding=utf-8"
                        userId="root"
                        password="123456">
        </jdbcConnection>

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

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

        <sqlMapGenerator targetPackage="mapping"  targetProject="src/main/resources">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

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

        <table schema="mall" tableName="mall_order" domainObjectName="Order" >
<!--            <property name="useActualColumnNames" value="true"/>-->
<!--            <generatedKey column="ID" sqlStatement="DB2" identity="true" />-->
<!--            <columnOverride column="DATE_FIELD" property="startDate" />-->
<!--            <ignoreColumn column="FRED" />-->
<!--            <columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR" />-->
        </table>

    </context>
</generatorConfiguration>

 

3.命令

mvn -Dmybatis.generator.overwrite=true mybatis-generator:generate

 4.配置删除emample

<table schema="mall" tableName="mall_order" domainObjectName="Order" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" selectByExampleQueryId="false"/>

 

5.配置xml不追加

        <plugin type="org.mybatis.generator.plugins.UnmergeableXmlMappersPlugin" />

 

6.删除注释

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