springboot集成swagger knife4j 最详细的步骤 手把手教你继承swagger
效果图
Knife4j介绍
Knife4j的前身是swagger-bootstrap-ui,前身swagger-bootstrap-ui是一个纯swagger-ui的ui皮肤项目
一开始项目初衷是为了写一个增强版本的swagger的前端ui,但是随着项目的发展,面对越来越多的个性化需求,不得不编写后端Java代码以满足新的需求,在swagger-bootstrap-ui的1.8.5~1.9.6版本之间,采用的是后端Java代码和Ui都混合在一个Jar包里面的方式提供给开发者使用.这种方式虽说对于集成swagger来说很方便,只需要引入jar包即可,但是在微服务架构下显得有些臃肿。

@Bean(value = "defaultApi2")
public Docket defaultApi2() {
Docket docket=new Docket(DocumentationType.SWAGGER_2)
.apiInfo(new ApiInfoBuilder()

.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.example.swaggerdemo.controller"))
.paths(PathSelectors.any())
.build().globalOperationParameters(this.settoken());
return docket;
}
private List<Parameter> settoken() {
Parameter tokenParam = (new ParameterBuilder()).name("token").description("token 认证码").modelRef(new ModelRef("string")).parameterType("header").required(false).build();
return Lists.newArrayList(new Parameter[]{
tokenParam});
}
}
3. controller文件

import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@Api(tags = "首页模块")
@RestController
public class IndexController {
@ApiImplicitParam(name = "name",value = "姓名",required = true)
@ApiOperation(value = "向客人问好")
@GetMapping("/sayHi")
public ResponseEntity<String> sayHi(@RequestParam(value = "name")String name){
return ResponseEntity.ok("Hi:"+name);
}
}
