Mybatis-Generator_学习_02_使用Mapper专用的MyBatis Generator插件

源码见：https://github.com/shirayner/tk-mybatis-generator

一、要点

二、具体实现

1.项目结构

2.配置 pm.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">
    <parent>
        <artifactId>study-parent</artifactId>
        <groupId>com.ray.study</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>    <modelVersion>4.0.0</modelVersion>
    <packaging>jar</packaging>
    <artifactId>tk-mybatis-generator</artifactId>    <properties>
        <!--  MyBatis Generator  -->
        <!--  Java接口和实体类  -->
        <targetJavaProject>${basedir}/src/main/java</targetJavaProject>
        <targetMapperPackage>tk.mybatis.mapper.mapper</targetMapperPackage>
        <targetModelPackage>tk.mybatis.mapper.model</targetModelPackage>
        <!--  XML生成路径  -->
        <targetResourcesProject>${basedir}/src/main/resources</targetResourcesProject>
        <targetXMLPackage>mapper</targetXMLPackage>
        <!--  依赖版本  -->
        <mapper.version>3.4.6</mapper.version>
        <mysql.version>5.1.6</mysql.version>
    </properties>    <build>
        <finalName>mmall</finalName>
        <plugins>
            <!--1.mybatis-generator 使用通用mapper实现的-->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
                    <overwrite>true</overwrite>
                    <verbose>true</verbose>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>${mysql.version}</version>
                    </dependency>
                    <dependency>
                        <groupId>tk.mybatis</groupId>
                        <artifactId>mapper</artifactId>
                        <version>${mapper.version}</version>
                    </dependency>
                </dependencies>
            </plugin>        </plugins>    </build></project>

3.配置 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>
    <properties resource="config.properties"/>    <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>        <plugin type="${mapper.plugin}">
            <property name="mappers" value="${mapper.Mapper}"/>
        </plugin>        <jdbcConnection driverClass="${jdbc.driverClass}"
                        connectionURL="${jdbc.url}"
                        userId="${jdbc.user}"
                        password="${jdbc.password}">
        </jdbcConnection>        <javaModelGenerator targetPackage="${targetModelPackage}" targetProject="${targetJavaProject}"/>        <sqlMapGenerator targetPackage="${targetXMLPackage}"  targetProject="${targetResourcesProject}"/>        <javaClientGenerator targetPackage="${targetMapperPackage}" targetProject="${targetJavaProject}" type="XMLMAPPER" />        <table tableName="%" >
            <generatedKey column="id" sqlStatement="Mysql" identity="true"/>
        </table>
    </context>
</generatorConfiguration>

4. 配置 config.properties

# 数据库配置
jdbc.driverClass = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/mmall
jdbc.user = root
jdbc.password =123#c3p0
jdbc.maxPoolSize=50
jdbc.minPoolSize=10
jdbc.maxStatements=100
jdbc.testConnection=true# 通用Mapper配置
mapper.plugin = tk.mybatis.mapper.generator.MapperPlugin
mapper.Mapper = tk.mybatis.mapper.common.Mapper
