idea自動生成mybatis-xml文件

idea自動生成mybatis文件

1、在pom.xml中添加org.mybatis.generator插件

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
        <plugin>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-maven-plugin</artifactId>
            <version>1.3.2</version>

        </plugin>
    </plugins>
</build>

2、添加generator運行選項

在Command line中添加如下代碼

mybatis-generator:generate -e

3、在resources下建立generatorConfig.xml 內容如下

<?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>
    <!-- 數據庫驅動:選擇你的本地硬盤上面的數據庫驅動包-->
    <classPathEntry  location="D:\a_javaConfiig\maven\Maven_Repository\mysql\mysql-connector-java\5.1.29\mysql-connector-java-5.1.29.jar"/>
    <context id="DB2Tables"  targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <!-- 是否去除自動生成的注釋 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--數據庫鏈接URL，用戶名、密碼 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/jazkwl?useUnicode=true"
                        userId="root" password="root">
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>

        <!-- 生成模型的包名和位置-->
        <javaModelGenerator targetPackage="com.zzbeilei.dsly.pojo" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!-- 生成映射文件的包名和位置-->
        <sqlMapGenerator targetPackage="com.zzbeilei.dsly.dao" targetProject="src/main/resources">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>

        <!-- 生成DAO的包名和位置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.zzbeilei.dsly.dao" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <!-- 要生成的表 tableName是數據庫中的表名或視圖名 domainObjectName是實體類名-->
        <table tableName="gs_aboutu" domainObjectName="GsAboutu" enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        <table tableName="gs_account" domainObjectName="GsAccount" enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        <table tableName="gs_yundlb" domainObjectName="GsYundlb" enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
    </context>
</generatorConfiguration>

4 自動生成的xml文件結構如下

<?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" >

    insert into gs_account (id, user_id, desc,

      tit)
    values (#{id,jdbcType=INTEGER}, #{userId,jdbcType=INTEGER}, #{desc,jdbcType=VARCHAR},
