maven配置使用mybatis逆向工程

一、创建maven工程

二、修改pom.xml，如下

<?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.scau</groupId>
    <artifactId>mybatis-generator-demo</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>3.3.0</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.35</version>
        </dependency>
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-maven-plugin</artifactId>
            <version>1.3.2</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <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>
        </plugins>
    </build>
</project>

三、在resource文件夹下新建generatorConfig.xml与config.properties，mybatis官网可以找到generatorConfig.xml的示例

generatorConfig.xml内容如下：

<?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>
    <!-- 引入config配置文件   -->
    <properties resource="config.properties"/>
    <classPathEntry
            location="D:\maven\maven-repoitory\mysql\mysql-connector-java\5.1.35\mysql-connector-java-5.1.35.jar"/>
    <context id="generate" targetRuntime="MyBatis3" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>


        <!--支持序列化-->
        <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin>

        <commentGenerator>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true" />
        </commentGenerator>

        <jdbcConnection driverClass="${jdbc.driverClass}"
                        connectionURL="${jdbc.url}"
                        userId="${jdbc.user}"
                        password="${jdbc.password}">
        </jdbcConnection>

        <javaModelGenerator targetPackage="${targetModelPackage}" targetProject="${targetJavaProject}">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
            <!-- 从数据库返回的值被清理前后的空格 -->
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="${targetXMLPackage}" targetProject="${targetResourcesProject}">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>

        <javaClientGenerator targetPackage="${targetMapperPackage}" targetProject="${targetJavaProject}" type="XMLMAPPER">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>

        <!--设置要参与逆向工程的数据库表-->
        <!--这里设置不生成example类-->
        <table schema="" tableName="t_user"
               enableCountByExample="false"
               enableUpdateByExample="false"
               enableDeleteByExample="false"
               enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>
    </context>
</generatorConfiguration>

config.properties文件内容如下

# 配置数据库连接
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/cloud-demo-1
jdbc.user=root
jdbc.password=445221

# 设置生成mapper接口、mapper.xml、实体类的保存位置
targetModelPackage=com.scau.mybatis.entity
targetXMLPackage=com.scau.mybatis.mapper
targetMapperPackage=com.scau.mybatis.mapper
targetJavaProject=src/main/java
targetResourcesProject=src/main/java

四、启动测试，如图，双击mybatis-generator:generate即可

这样就能看到自动生成的文件了，如果没有看到，则刷新一下工程即可

PS：如果有什么地方写错，请指出，谢谢
