MyBatis插件generator的使用(idea)

1.先创建一个maven项目

在pom下依赖插件库:

<!--mybatis 插件-->
<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.2</version>
    <configuration>
        <verbose>true</verbose>
        <overwrite>true</overwrite>
    </configuration>
</plugin>
<!--mybatis-generator依赖包以及插件-->
<dependency>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-core</artifactId>
    <version>1.3.2</version>
</dependency>

完整代码如下:

pom.xml:

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <!-- FIXME change it to the project's website -->

        <maven.compiler.target>1.7</maven.compiler.target>
    </properties>

    <dependencies>

        <!--单元测试-->

    </dependencies>

    <build>

        <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) -->

                </plugin>
                <!-- see http://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_war_packaging -->

                </plugin>
            </plugins>
        </pluginManagement>
    </build>
</project>

2.创建文件夹及文件

generator.properties

jdbc.driverLocation=/Users/gaodun/Downloads/mavenFactory3.5.4/mysql/mysql-connector-java/5.1.46/mysql-connector-java-5.1.46.jar
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.connectionURL=jdbc:mysql://localhost:3306/Fly
jdbc.userId=root
jdbc.password=12345678

generatorConfig.xml

<?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>
    <!--导入属性配置-->
    <properties resource="generator.properties"></properties>

    <!--指定特定数据库的jdbc驱动jar包的位置-->
    <classPathEntry location="${jdbc.driverLocation}"/>

    <!-- 一个数据库一个context -->
    <context id="default" targetRuntime="MyBatis3">

        <!-- optional,旨在创建class时,对注释进行控制 -->
        <commentGenerator>
            <property name="suppressDate" value="true"/>  <!-- 是否取消注释 -->
            <property name="suppressAllComments" value="true"/> <!-- 是否生成注释代时间戳-->
        </commentGenerator>

        <!--jdbc的数据库连接 -->
        <jdbcConnection
                driverClass="${jdbc.driverClass}"
                connectionURL="${jdbc.connectionURL}"
                userId="${jdbc.userId}"
                password="${jdbc.password}">
        </jdbcConnection>


        <!-- 非必需,类型处理器,在数据库类型和java类型之间的转换控制-->
        <javaTypeResolver>
            <!-- 是否使用bigDecimal, false可自动转化以下类型(Long, Integer, Short, etc.) -->
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>


        <!-- Model模型生成器,用来生成含有主键key的类,记录类 以及查询Example类
            targetPackage     指定生成的model生成所在的包名
            targetProject     指定在该项目下所在的路径
        -->
        <javaModelGenerator targetPackage="com.kuanquan.model"
                            targetProject="src/main/java">

            <!-- 是否在当前路径下新加一层schema,eg:fase路径cn.ffcs.test.domain", true:cn.ffcs.test.domain".[schemaName] -->
            <!-- 是否允许子包,即targetPackage.schemaName.tableName -->
            <property name="enableSubPackages" value="false"/>
            <!-- 是否对model添加 构造函数 -->

            <!-- 是否对类 char (String) 类型的列的数据进行trim操作 -->
            <property name="trimStrings" value="true"/>
            <!-- 建立的Model对象是否 不可改变  即生成的Model对象不会有 setter方法,只有构造方法 -->
            <property name="immutable" value="false"/>
        </javaModelGenerator>

        <!-- 生成mapxml文件  Mapper映射文件生成所在的目录 为每一个数据库的表生成对应的SqlMap文件 -->
        <sqlMapGenerator targetPackage="com.kuanquan.mapper"
                         targetProject="src/main/java">
            <!-- 是否在当前路径下新加一层schema,eg:fase路径cn.ffcs.test.domain", true:cn.ffcs.test.domain".[schemaName] -->
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>

        <!-- 客户端代码,生成易于使用的针对Model对象和XML配置文件 的代码
                type="ANNOTATEDMAPPER",生成Java Model 和基于注解的Mapper对象

                type="XMLMAPPER",生成SQLMap XML文件和独立的Mapper接口
        -->
        <!-- 生成mapxml对应client,也就是接口dao -->
        <javaClientGenerator targetPackage="com.kuanquan.dao"
                             targetProject="src/main/java" type="XMLMAPPER">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>


        <!-- 指定数据库表 -->
        <table schema="" tableName="user" domainObjectName="User"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">

            <!-- schema即为数据库名 tableName为对应的数据库表 domainObjectName是要生成的实体类 enable*ByExample
				是否生成 example类   -->

            <!-- 忽略列,不生成bean 字段
            <ignoreColumn column="FRED" />-->
            <!-- 指定列的java数据类型
              <columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR" />-->
        </table>

        <!--<table tableName="adminuser" domainObjectName="Admin"

               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>
        <table tableName="configinfo" domainObjectName="Confinfo"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"

               selectByExampleQueryId="false">
        </table>-->
    </context>
</generatorConfiguration>

最后一步也是最重要的一步:配置maven 生成代码

1.

2.

3.

命令:

mybatis-generator:generate -e
