【解决】Springboot配置swagger2无法扫描controller

controller

@RestController
@EnableAutoConfiguration
@RequestMapping("/system/dict")
@Api(value = "信息") //swagger2注解
public class DController {
    @Autowired
    private DService dService;
    
    @RequestMapping("/findDs")
    @ApiOperation(value = "查询所有信息",notes = "")//swagger2注解
    public List findDs(){
        Listlist=dService.list();
        return list;
    }

}

在启动类增加 @EnableSwagger2 注解

@SpringBootApplication
@MapperScan("com.xxx.system.mapper")
//开启swaggerUI注解 此句可以不加因为 SpringBootApplication 会自动扫描
//@ComponentScan(value = "com.xxx.config")
@EnableSwagger2
public class HApplication {
    public static void main(String[] args) {
        SpringApplication.run(HApplication.class,args);
    }
}

如果想自定义Swagger UI 页面中的内容，则需要手动自定义 Swagger2Config.java

package com.config;

import org.springframework.context.annotation.Bean;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.documentationType;
import springfox.documentation.spring.web.plugins.Docket;

@Configuration
//可以省去
@EnableSwagger2
public class Swagger2Config {
    @Bean
    public Docket webApiConfig(){
        return new Docket(documentationType.SWAGGER_2)
                .groupName("webApi")
                .apiInfo(webApiInfo()).enable(true)
                .select()
                .build();
    }
    //自定义项目文档内容
   private ApiInfo webApiInfo(){
        return new ApiInfoBuilder()
                //文档标题
               .title("API文档")
               //文档描述
               .description("管理系统")
                //文档版本
               .version("1.0")
                //作者及联系方式
               .contact(new Contact("xxx", "", "1234@qq.com"))
                .build();
    }
}
