SpringBoot项目常用配置类

分页插件配置

@Configuration
public class MybatisPlusConfig {

    @Bean
    public MybatisPlusInterceptor MybatisPlusInterceptor(){
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor());
        return interceptor;
    }
}

 

跨域配置

@Configuration
public class WebConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedOrigins("http://localhost:8080");
    }
}

 

定义统一返回值

@Data
@AllArgsConstructor
public class Result {

    private boolean success;

    private int code;

    private String msg;

    private Object data;

    public static Result success(Object data){
        return new Result(true,200,"success",data);
    }

    public static Result fail(int code, String msg){
        return new Result(false,code,msg,null);
    }
    
}
