mybatis-generator自动生成代码工具

1.在项目的配置文件中放入配置文件mybatis-generator-config.xml   根据情况修改下配置

<?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>

    <!-- !!!! Driver Class Path !!!! -->
    <classPathEntry location="/Users/dongjunjie/.m2/repository/mysql/mysql-connector-java/5.1.38/mysql-connector-java-5.1.38.jar"/>


    <context id="context" targetRuntime="MyBatis3">
        <plugin type="org.mybatis.generator.plugins.CaseInsensitiveLikePlugin" />
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
            <property name="suppressDate" value="true"/>
        </commentGenerator>

        <!-- !!!! Database Configurations !!!! -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://****/exchange?characterEncoding=utf-8"
                        userId="exchange" password="****"/>

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

        <!-- !!!! Model Configurations !!!! -->
        <javaModelGenerator targetPackage="com.cmcm.finance.wallet.sync.entity" targetProject="/Users/dongjunjie/IdeaProjects/wallet-sync/src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!-- !!!! Mapper XML Configurations !!!! -->
        <sqlMapGenerator targetPackage="sqlmapper" targetProject="/Users/dongjunjie/IdeaProjects/wallet-sync/src/main/java/com/*/finance/wallet/sync/dao">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>

        <!-- !!!! Mapper Interface Configurations !!!! -->
        <javaClientGenerator targetPackage="com.*.finance.wallet.sync.dao" targetProject="/Users/dongjunjie/IdeaProjects/wallet-sync/src/main/java" type="XMLMAPPER">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <!-- !!!! Table Configurations !!!! -->
        <table tableName="distribute_coin_detail" domainObjectName="DistributeCoinDetail" enableCountByExample="true" enableDeleteByExample="true" enableSelectByExample="true"
               enableUpdateByExample="true"/>

    </context>
</generatorConfiguration>

2. 添加maven 任务

 Edit-Configurations ->name  、work directory、Command line （mybatis-generator:generate -e ）

 3. pom 文件中添加 build  -plugin 

 <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <configurationFile>src/main/resources/dev/mybatis-generator-config.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <executions>
                    <execution>
                        <id>Generate MyBatis Artifacts</id>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                    </execution>
                </executions>
                <dependencies>
                    <dependency>
                        <groupId>org.mybatis.generator</groupId>
                        <artifactId>mybatis-generator-core</artifactId>
                        <version>1.3.2</version>
                    </dependency>
                </dependencies>
            </plugin>

4. 运行maven的自动生成插件 

    run-config 》 mybatis-gen -》右键 run 

   pom中添加Plugins 也可以在idea的maven project中 的Plugins中找到mybatis-generater 右键运行即可
