二、CodeGenerator.java

package com.rating;
 
import com.baomidou.mybatisplus.generator.FastAutoGenerator;
import com.baomidou.mybatisplus.generator.config.OutputFile;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;
 
import java.util.Collections;
 
public class CodeGenerator {
    public static void main(String[] args) {
        // 配置数据库
        String url = "jdbc:mysql:///rating_manage";
        String username = "root";
        String password = "root";
        String tables = "r_user"; // 设置需要生成的表名
        String tablePrefix = "r_"; // 设置过滤表前缀
        //String tables = "x_user,x_role,x_menu,x_user_role,x_role_menu";
        // 配置路径
        String projectPath = System.getProperty("user.dir");  // 项目路径
        String outputDir = projectPath + "\\src\\main\\java"; // 指定输出目录
        String packageName = "com.rating"; // 设置父包名
        String moduleName = "system";  // 设置父包模块名
        String mapperLocation = projectPath + "\\src\\main\\resources\\mapper\\" + moduleName; // 设置mapperXml生成路径
        FastAutoGenerator.create(url, username, password)
                .globalConfig(builder -> {
                    builder.outputDir(outputDir); // 指定输出目录
                            //.author("chwb") // 设置作者
                            //.enableSwagger() // 开启 swagger 模式
                            //.fileOverride(); // 覆盖已生成文件
                })
                .packageConfig(builder -> {
                    builder.parent(packageName) // 设置父包名
                            .moduleName(moduleName) // 设置父包模块名
                            .pathInfo(Collections.singletonMap(OutputFile.xml, mapperLocation)); // 设置mapperXml生成路径
                })
                .strategyConfig(builder -> {
                    builder.addInclude(tables) // 设置需要生成的表名
                            .addTablePrefix(tablePrefix) // 设置过滤表前缀
                            .entityBuilder().enableLombok()  //entity 包开启 lombok
                            .controllerBuilder().enableRestStyle(); // controller 包开启RestController模式
                            
                })
                .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
                .execute();
    }
