springboot+mybitis逆向工程

1.pom文件中添加依赖

<?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">

            <artifactId>druid</artifactId>

            <!-- mybatis逆向工程插件 -->
            <!--mybaits逆向工程-->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>

                <configuration>

                    <overwrite>true</overwrite>
                </configuration>
            </plugin>

        </plugins>
    </build>

</project>

 

2.在src下创建MBG.xml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="DB2Tables" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressAllComments" value="true" />
        </commentGenerator>

        <jdbcConnection
                driverClass="com.mysql.jdbc.Driver"
                connectionURL="jdbc:mysql://localhost:3306/jcsg"
                userId="root"
                password="123456">
        </jdbcConnection>

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

        <!--指定Javabean生成的位置-->
        <javaModelGenerator targetPackage="com.example.demo.bean" targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!--指定sql映射文件生成的位置-->
        <sqlMapGenerator targetPackage="mapper"  targetProject=".\src\main\resources">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <!--指定dao接口生成的位置，mapper接口生成的位置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.example.demo.dao"  targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <!--指定每个表的生成策略-->

        <table tableName="is_user" domainObjectName="User"></table>


    </context>

</generatorConfiguration>

 

 

3.在test包下创建测试类，并运行

package com.example.demo;

import java.io.File;
import java.util.ArrayList;
import java.util.List;


import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.internal.DefaultShellCallback;


public class MbgTest {
    public static void main(String args[]) throws Exception{
        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        File configFile = new File("src/MBG.xml");
        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(configFile);
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(null);

    }

}
