首页 > 解决方案 > 无法从 swagger UI 中的控制器获取我的端点列表

问题描述

我是使用 Swagger UI 的 Spring Boot 新手。我只是想将我的 Rest 控制器端点配置为在 swagger UI 屏幕上显示,但它显示 No operation for specs defined。很确定,这是一个配置问题。

我试过@EnableAutoConfiguration,还是找不到控制器

SwaggerDemoApplication.java

package com.example.config;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SwaggerDemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(SwaggerDemoApplication.class, args);
 }

}

SwaggerConfig.java

package com.example.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
import static springfox.documentation.builders.PathSelectors.regex;

@EnableSwagger2
@Configuration

public class SwaggerConfig {

 @Bean
 public Docket productApi() {
     return new Docket(DocumentationType.SWAGGER_2)  
              .select()                                  
              .apis(RequestHandlerSelectors.basePackage("com.example.controller"))              
              .paths(regex("/test.*"))                       
              .build();                                           

 } 
}



TestController.java

package com.example.controller;


import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import io.swagger.annotations.Api;

@RestController
@RequestMapping(value = "/test")
@Api(value="onlinestore", description="Operations pertaining to products in Online Store")
public class TestController {

    @RequestMapping(value = "/test-swagger", method= RequestMethod.GET)
    public String home() {
        return "Spring is here!";
    }

}

预期:休息端点实际:规范中未定义操作

解决方案


我和你有完全相同的问题,这是由于我的@SpringBootApplication班级安排错误造成的,就像你遇到的一样。

(在代码片段中,我故意省略了不太相关的注释,它们仍然必须存在,就像您在帖子中一样。

我还引用了“under”、“root package”等词,因为从技术上讲,Java 无法识别“子包”之类的东西。Java 中的所有包都处于同一“级别”,即使 Web 域的点和相似之处“误导”我们对它们进行分层思考。然而, Spring广泛适用于“子包”和“根包”。)

package com.example.config;
@SpringBootApplication
public class SwaggerDemoApplication {
    ...
}

package com.example.config;
@EnableSwagger2
public class SwaggerConfig {
      ...
      .apis(RequestHandlerSelectors.basePackage("com.example.controller"))              
      ...
}

@RestController
package com.example.controller; // notice that this is not "under" com.example.config where SwaggerDemoApplication resides
public class TestController {
    ....
}

我观察到,如果@SpringBootApplication该类不在该类的“根包”中@RestController,它会破坏自动魔术行为,并且在调用中设置的包名将apis(...)被忽略,并且不会扫描包。老实说,我不太确定应该如何apis()工作以及它是错误还是功能

要在不添加的情况下修复它@ComponentScan,您的包组织应该是这样的:

package com.example.myapplication; // the main class is placed in the "root" package
@SpringBootApplication
public class SwaggerDemoApplication {
    ...
}

package com.example.myapplication.config;
@EnableSwagger2
public class SwaggerConfig {
      ...
      .apis(RequestHandlerSelectors.basePackage("com.example.myapplication"))
      ...
}

package com.example.myapplication.controller;
@RestController
public class TestController {
    ...
}

您还可以通过指定进一步过滤 API 扫描

.apis(
    withClassAnnotation(RestController.class)
    .and(basePackage("com.example.myapplication.controller))
)
