一、写在前面

spring5 + mybatis-plus3 自动生成 Entity、Mapper、Mapper XML、Service、Controller 等各个模块的代码。

 

二、具体实现

1.maven依赖

<dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.0.3.RELEASE</version> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus</artifactId> <version>3.2.0</version> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-generator</artifactId> <version>3.2.0</version> </dependency> <dependency> <groupId>org.apache.velocity</groupId> <artifactId>velocity-engine-core</artifactId> <version>2.0</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.48</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.25</version> </dependency>

2.主要代码

package com.yale.utils; import com.baomidou.mybatisplus.generator.AutoGenerator; import com.baomidou.mybatisplus.generator.config.DataSourceConfig; import com.baomidou.mybatisplus.generator.config.GlobalConfig; import com.baomidou.mybatisplus.generator.config.PackageConfig; import com.baomidou.mybatisplus.generator.config.StrategyConfig; import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy; import org.springframework.core.io.support.ResourcePropertySource; public class CodeGenerator { public static void main(String[] args) throws Exception { //读取jdbc.properties ResourcePropertySource propertySource = new ResourcePropertySource("jdbc.properties"); // 代码生成器 AutoGenerator mpg = new AutoGenerator(); // 全局配置 GlobalConfig gc = new GlobalConfig(); gc.setOutputDir("D:\\work\\workspace\\novel_maven\\src\\main\\java");//输出文件夹 gc.setOpen(false); //关闭自动打开输出文件夹 mpg.setGlobalConfig(gc); // 包配置 PackageConfig pc = new PackageConfig(); pc.setParent("com.yale.test"); mpg.setPackageInfo(pc); // 策略配置 StrategyConfig strategy = new StrategyConfig(); strategy.setNaming(NamingStrategy.underline_to_camel); //驼峰命名 strategy.setColumnNaming(NamingStrategy.underline_to_camel); //驼峰命名 strategy.setInclude("user", "novel_chapter"); //指定数据库表 mpg.setStrategy(strategy); // 数据源配置 DataSourceConfig dsc = new DataSourceConfig(); dsc.setUrl((String)propertySource.getProperty("jdbc.url")); dsc.setDriverName((String) propertySource.getProperty("jdbc.driver")); dsc.setUsername((String) propertySource.getProperty("jdbc.username")); dsc.setPassword((String) propertySource.getProperty("jdbc.password")); mpg.setDataSource(dsc); //执行 mpg.execute(); } }

3.目录结构

 

4.jdbc配置

jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/novel?useUnicode=true&characterEncoding=utf8 jdbc.username=root jdbc.password=root
