    4.使用mybatis-plus生成类，接口等

    1. package com.wzh;

    4. import com.baomidou.mybatisplus.generator.config.OutputFile;
    5. import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;
    6.  
    7. import java.util.Collections;
    8.  
    9. /**
    10.  * @ProjectName: springboot-vue0809
    11.  * @Package: com.wzh
    12.  * @ClassName: Generator

    17.  */
    18. public class Generator {
    19.     public static void main(String[] args) {
    20.         FastAutoGenerator.create("jdbc:mysql://localhost:3306/weixin?serverTimezone=Asia/Shanghai", "root", "123456")
    21.                 .globalConfig(builder -> {
    22.                     builder.author("王振华") // 设置作者
    23.                             .enableSwagger() // 开启 swagger 模式
    24.                             .fileOverride() // 覆盖已生成文件
    25.                             .outputDir(".\\src\\main\\java\\"); // 指定输出目录
    26.                 })
    27.                 .packageConfig(builder -> {
    28.                     builder.parent("com.wzh") // 设置父包名
    29.                             //.moduleName("") // 设置父包模块名
    30.                             .pathInfo(Collections.singletonMap(OutputFile.xml, "src\\main\\resources\\mapper\\")); // 设置mapperXml生成路径

    32.                 .strategyConfig(builder -> {
    33.                     builder.addInclude( "t_order","t_pay_log")// 设置需要生成的表名
    34.                             .addTablePrefix("t_"); // 设置过滤表前缀
    35.                 })
    36.                 .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
    37.                 .execute();
    38.  
    39.     }
    40. }

    5.后端

    config配置类：

    解决跨域：

    1. package com.wzh.config;
    2.  
    3. import org.springframework.context.annotation.Bean;
    4. import org.springframework.context.annotation.Configuration;
    5. import org.springframework.web.cors.CorsConfiguration;
    6. import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
    7. import org.springframework.web.filter.CorsFilter;
    8.  
    9. @Configuration
    10. public class CorsConfig {
    11.  
    12.     // 当前跨域请求最大有效时长。这里默认1天
    13.     private static final long MAX_AGE = 24 * 60 * 60;
    14.  
    15.     @Bean
    16.     public CorsFilter corsFilter() {
    17.         UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    18.         CorsConfiguration corsConfiguration = new CorsConfiguration();
    19.         corsConfiguration.addAllowedOrigin("*"); // 1 设置访问源地址
    20.         corsConfiguration.addAllowedHeader("*"); // 2 设置访问源请求头
    21.         corsConfiguration.addAllowedMethod("*"); // 3 设置访问源请求方法
    22.         corsConfiguration.setMaxAge(MAX_AGE);
    23.         source.registerCorsConfiguration("/**", corsConfiguration); // 4 对接口配置跨域设置
    24.         return new CorsFilter(source);
    25.     }
    26. }

    mybatis-plus添加修改自动生成：

    1. package com.wzh.config;
    2.  
    3. import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
