MyBatis Generator的简单使用

目的是快速进入项目使用状态，具体的参数配置可以后期修改（如数据库连接、配置文件目录位置等）

1、POM中加入插件

    <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.7</version>
        <configuration>
          <verbose>true</verbose>
          <overwrite>true</overwrite>
        </configuration>
        <dependencies>
          <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>${mysql-connector.version}</version>
          </dependency>
          <dependency>
            <groupId>com.itfsw</groupId>
            <artifactId>mybatis-generator-plugin</artifactId>
            <version>1.2.10</version>
          </dependency>
        </dependencies>
      </plugin>

2、在resources目录加创建generatorConfig.xml配置文件

<?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>

    <context id="mysql" defaultModelType="flat" targetRuntime="MyBatis3">

        <property name="autoDelimitKeywords" value="false"/>

        <property name="javaFileEncoding" value="UTF-8"/>

        <property name="javaFormatter" value="org.mybatis.generator.api.dom.DefaultJavaFormatter"/>

        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        <plugin type="com.itfsw.mybatis.generator.plugins.LimitPlugin"/>
        <plugin type="com.itfsw.mybatis.generator.plugins.ExampleEnhancedPlugin"/>
        <plugin type="com.itfsw.mybatis.generator.plugins.ExampleTargetPlugin">
            <!-- 修改Example类生成到目标包下 -->
            <property name="targetPackage" value="com.test.pay.finance.example"/>
        </plugin>
        
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://xxxx.com:3306/test"
                        userId="test"
                        password="123456">
        </jdbcConnection>

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

        <javaModelGenerator targetPackage="com.test.pay.finance.entity" targetProject="src/main/java">
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="com.test.pay.finance.mapper" targetProject="src/main/resources">
        </sqlMapGenerator>

        <javaClientGenerator type="MIXEDMAPPER" targetPackage="com.test.pay.finance.mapper"  targetProject="src/main/java" />

        <table schema="finance" tableName="arrival_reminder" >
            <property name="useActualColumnNames" value="true"/>
            <generatedKey column="id" sqlStatement="MySql" identity="true" />
            <!-- 生成的实体类等去掉表名的前缀。注意，与正则要写驼峰转化后的。或者在table标签添加domainObjectName属性直接指定 -->
            <domainObjectRenamingRule searchString="^T" replaceString=""/>
        </table>

    </context>
</generatorConfiguration>
