SpringBoot集成Knife4j

添加pom依赖

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency>

新增配置类Knif4jConfiguration

法一：使用@EnableSwagger2WebMvc

/*** @author Hmoumou* @DATE 2021/11/3* @apiNote*/
@Configuration
@EnableSwagger2WebMvc
public class Knife4jConfiguration {@Bean(value = "defaultApi2")public Docket defaultApi2() {Docket docket=new Docket(DocumentationType.SWAGGER_2).apiInfo(new ApiInfoBuilder()//.title("swagger-bootstrap-ui-demo RESTful APIs").description("# swagger-bootstrap-ui-demo RESTful APIs").termsOfServiceUrl("http://www.xx.com/").contact("xx@qq.com").version("1.0").build())//分组名称.groupName("2.X版本").select()//这里指定Controller扫描包路径.apis(RequestHandlerSelectors.basePackage("com.springweb.demo3.controller")).paths(PathSelectors.any()).build();return docket;}
}

法二

很奇怪的问题，有一次项目使用上面的注解出现Knife4j文件请求异常

遂改用如下配置，问题消失；

/*** @author Hmoumou* @DATE 2021/11/3* @apiNote*/
@Configuration
@EnableSwagger2
@EnableKnife4j
public class Knife4jConfiguration {@Beanpublic Docket createRestApi() {return  new Docket(DocumentationType.SWAGGER_2).useDefaultResponseMessages(false).apiInfo(apiInfo()).groupName("1.0版本").select().apis(RequestHandlerSelectors.any()).paths(PathSelectors.any()).build();}private ApiInfo apiInfo() {return new ApiInfoBuilder().title("test").description("后端APIS").termsOfServiceUrl("http://localhost:9999/").contact("test@qq.com").version("1.0").build();}
}

使用

/*** @author Hmoumou* @DATE 2021/11/3* @apiNote*/测试模块")
@RestController
public class IndexController {@ApiImplicitParam(name = "name",value = "姓名",required = true)@ApiOperation(value = "测试")@GetMapping("/test")public ResponseEntity<String> sayHi(@RequestParam(value = "name")String name){return ResponseEntity.ok("Hi:"+name);}
}

启动

​ 配置完毕后，访问eghttp://localhost:9999/doc.html
