使用Mybatis-puls逆向生成文件 (悄悄的偷个懒)

第一步导入依赖


               
    
     org.projectlombok
                
    
     lombok
                
    
     1.18.12
            
           
               
    
     mysql
                
    
     mysql-connector-java
                
    
     8.0.22
            
           
               
    
     com.baomidou
                
    
     mybatis-plus-boot-starter
                
    
     3.3.1.tmp
            
           
               
    
     com.baomidou
                
    
     mybatis-plus-generator
                
    
     3.3.1.tmp
            
           
               
    
     org.apache.velocity
                
    
     velocity
                
    
     1.7

第二步编写代码

package com.jsp;import com.baomidou.mybatisplus.annotation.DbType;import com.baomidou.mybatisplus.core.exceptions.MybatisPlusException;import com.baomidou.mybatisplus.core.toolkit.StringUtils;import com.baomidou.mybatisplus.generator.AutoGenerator;import com.baomidou.mybatisplus.generator.config.*;import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;import java.util.Scanner;public class CodeGenerator {
       public static String scanner(String table) {
           Scanner scanner = new Scanner(System.in);        StringBuilder builder = new StringBuilder();        builder.append("请输入" + table + "：");        System.out.println(builder.toString());        if (scanner.hasNext()) {
               String input = scanner.next();            if (StringUtils.isNotEmpty(input)) {
                   return input;            }        }        throw new MybatisPlusException("请输入正确的" + table + "！");    }    public static void main(String[] args) {
           //创建generator对象        AutoGenerator autoGenerator = new AutoGenerator();        //数据源        DataSourceConfig dataSourceConfig = new DataSourceConfig();        dataSourceConfig.setDbType(DbType.MYSQL);        dataSourceConfig.setUrl("jdbc:mysql://localhost:3306/DB?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai");        dataSourceConfig.setUsername("username");        dataSourceConfig.setPassword("password");        dataSourceConfig.setDriverName("com.mysql.cj.jdbc.Driver");        autoGenerator.setDataSource(dataSourceConfig);        //全局配置        GlobalConfig globalConfig = new GlobalConfig();        globalConfig.setOutputDir(System.getProperty("user.dir")+"/src/main/java");        globalConfig.setOpen(false);        globalConfig.setAuthor("author");        globalConfig.setServiceName("%sService");        autoGenerator.setGlobalConfig(globalConfig);        //包信息        PackageConfig packageConfig = new PackageConfig();        packageConfig.setParent("com.jsp");        //packageConfig.setModuleName("generator");        packageConfig.setController("controller");        packageConfig.setService("service");        packageConfig.setServiceImpl("service.impl");        packageConfig.setMapper("mapper");        packageConfig.setEntity("entity");        autoGenerator.setPackageInfo(packageConfig);        //配置策略        StrategyConfig strategyConfig = new StrategyConfig();        strategyConfig.setEntityLombokModel(true);        strategyConfig.setNaming(NamingStrategy.underline_to_camel);        strategyConfig.setColumnNaming(NamingStrategy.underline_to_camel);        strategyConfig.setRestControllerStyle(true);        strategyConfig.setInclude(scanner("表名，多个英文逗号分割").split(","));        strategyConfig.setControllerMappingHyphenStyle(true);        strategyConfig.setTablePrefix("m_");        autoGenerator.setStrategy(strategyConfig);        autoGenerator.execute();    }}
