.新建maven空項目

2.修改pom.xml文件

<?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">
    <modelVersion>4.0.0</modelVersion
 
>

    <groupId>com.lolaage.mybatis.generator</groupId>
    <artifactId>mpmt-mybatis-generator</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <

        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>

        <plugins>
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <!--配置文件的位置-->
                    <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <executions>
                    <execution>

                        </goals>
                    </execution>
                </executions>
                <dependencies>
                    <dependency>

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

</project>

3. 新增generatorConfig.xml 文件 ，修改標註部分內容

<?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>
    <!--mysql 連接數據庫jar 這裏選擇自己本地位置-->

    <context id="testTables" targetRuntime="MyBatis3">
        <commentGenerator>
            <!-- 是否去除自動生成的註釋 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true" />
        </commentGenerator>
        <!--數據庫連接的信息：驅動類、連接地址、用戶名、密碼 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://192.168.100.76:3306/possecu_mpmt_1?characterEncoding=utf8" userId="root"
                        password="root">
        </jdbcConnection>
        <!-- 默認false，把JDBC DECIMAL 和 NUMERIC 類型解析為 Integer，為 true時把JDBC DECIMAL 和
           NUMERIC 類型解析為java.math.BigDecimal -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!-- targetProject:生成PO類的位置 -->
        <javaModelGenerator targetPackage="com.lolaage.demo.model"
                            targetProject="src/main/java">
            <!-- enableSubPackages:是否讓schema作為包的後綴 -->
            <property name="enableSubPackages" value="false" />
            <!-- 從數據庫返回的值被清理前後的空格 -->
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <!-- targetProject:mapper映射文件生成的位置
           如果maven工程只是單獨的一個工程，targetProject="src/main/java"
           若果maven工程是分模塊的工程，targetProject="所屬模塊的名稱"，例如：
           targetProject="ecps-manager-mapper"，下同-->
        <sqlMapGenerator targetPackage="com.lolaage.demo.mapping"
                         targetProject="src/main/java">
            <!-- enableSubPackages:是否讓schema作為包的後綴 -->
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>
        <!-- targetPackage：mapper接口生成的位置 -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.lolaage.demo.dao"
                             targetProject="src/main/java">
            <!-- enableSubPackages:是否讓schema作為包的後綴 -->
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>
        <!-- 指定數據庫表和實體對象名稱 -->
        <!--<table schema="" tableName="t_third_system_serviceKey"></table>-->
        <table tableName="t_test" domainObjectName="Test" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

    </context>
</generatorConfiguration>

修復xml文件頭部標紅提示的問題

4.運行mybatis-generator插件

點擊Maven Project --->mpmt-mybatis-generator--->Plugins-->mybatis-generator-->Mybatis-generator:generate

5.輸出結果

mpmt-mybatis-generator.zip

mybatis-generator 動態生成實體對象、dao 以及相關的xml映射文件
