Spring Boot 2 整合Swagger簡單入門

Swagger是一款RESTFUL接口的文檔在線自動生成+功能測試功能軟件。html

一、pom.xml添加配置web

能夠到http://mvnrepository.com上搜索springfox,即可以看到Springfox Swagger2和Springfox Swagger Ui的版本。spring

    <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>

二、swagger的configurationapi

package com.example.demo;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import io.swagger.annotations.ApiOperation;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //.apis(RequestHandlerSelectors.basePackage("com.example.demo.web"))//包所在位置
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.any()).build().useDefaultResponseMessages(false);
    }

    /**
     * 獲取swagger ApiInfo
     *
     * @return
     */
    private static ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("API文檔")
                .description("Swagger API 文檔")
                .termsOfServiceUrl("http://www.cnblogs.com/gdjlc")
                .version("1.0")
                .contact(new Contact("name..", "url..", "email.."))
                .build();
    }
}

三、Controller中測試方法app

package com.example.demo.web;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;

@RestController
@Api(value = "UserController", tags = "用戶操做相關接口")
public class UserController {
                
    @ResponseBody    
    @GetMapping("/helloWorld")
    @ApiOperation(value="測試value", notes = "測試notes")
    @ApiImplicitParam(paramType="query", name = "userName", value = "用戶編號", required = true, dataType = 

"String")
    public String helloWorld(@RequestParam String userName){
        return "hello world," + userName;
    }
}

Swagger使用的註解及其說明:
@Api:用在類上,說明該類的做用。
@ApiOperation:註解來給API增長方法說明。
@ApiImplicitParams : 用在方法上包含一組參數說明。
@ApiImplicitParam:用來註解來給方法入參增長說明。
@ApiResponses:用於表示一組響應
@ApiResponse:用在@ApiResponses中,通常用於表達一個錯誤的響應信息
@ApiModel:描述一個Model的信息測試

 

訪問:項目地址/swagger-ui.html,如個人http://localhost:9001/swagger-ui.html
結果以下,能夠點擊方法右邊的【Try it out】按鈕開始測試,以後輸入參數,點擊【Execute】執行查看結果。ui
