小編給大家分享一下Spring boot集成swagger2如何生成接口文檔,希望大家閱讀完這篇文章之后都有所收獲,下面讓我們一起去探討吧!
一、Swagger介紹
Swagger是一個規(guī)范和完整的框架,用于生成、描述、調用和可視化RESTful風格的web服務。目標是使客戶端和文件系統(tǒng)作為服務器以同樣的速度來更新文件的方法,參數(shù)和模型緊密集成到服務器。這個解釋簡單點來講就是說,swagger是一款可以根據restful風格生成的接口開發(fā)文檔,并且支持做測試的一款中間軟件。
二、使用swagger優(yōu)勢
1、對于后端開發(fā)人員來說
不用再手寫Wiki接口拼大量參數(shù),避免手寫錯誤
對代碼侵入性低,采用全注解的方式,開發(fā)簡單
方法參數(shù)名修改、新增、減少參數(shù)都可以直接生效,不用手動維護
缺點:增加了開發(fā)成本,寫接口還得再寫一套參數(shù)配置
2、對前端開發(fā)來說
后端只需要定義好接口,會自動生成文檔,接口功能、參數(shù)一目了然
聯(lián)調方便,如果出了問題,直接測試接口,實時檢查參數(shù)和返回值,就可以快速定位是前端還是后端的問題
3、對于測試來說
但對于測試沒有前端界面UI的功能,可以直接用它來測試接口
操作簡單,不用了解具體代碼就可以操作
三、springboot集成swagger使用
1、新建maven項目(結構如下:)
2、配置pom.xml文件
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.3.RELEASE</version> <relativePath/> </parent> <groupId>com.dds.sbswagger</groupId> <artifactId>sb-swagger</artifactId> <version>0.0.1-SNAPSHOT</version> <name>sb-swagger</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <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> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.6</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
3、程序啟動類
package com.dds.sbswagger; import lombok.extern.slf4j.Slf4j; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; /** * @author dds */ @SpringBootApplication @Slf4j public class SbSwaggerApplication { public static void main(String[] args) { SpringApplication.run(SbSwaggerApplication.class, args); log.info("\n----------------------------------------------------------\n\t" + "Application demo is running! Access URLs:\n\t" + "swagger-ui: \thttp://127.0.0.1:8080/swagger-ui.html\n\t" + "----------------------------------------------------------"); } }
4、SwaggerConfig配置類
package com.dds.sbswagger.config; import io.swagger.annotations.ApiOperation; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; 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; import java.util.Collections; /** * @author DDS * @date 2019/9/10 13:55 */ @Configuration @EnableSwagger2 public class SwaggerConfig { @Bean public Docket api() { return new Docket(DocumentationType.SWAGGER_2) .select() .apis(RequestHandlerSelectors.basePackage("com.dds.sbswagger.controller")) //加了ApiOperation注解的類,才生成接口文檔 .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)) .paths(PathSelectors.any()) .build() .apiInfo(apiInfo()); } private ApiInfo apiInfo() { return new ApiInfo( "Spring Boot項目集成Swagger實例文檔", "我的微信公眾號:大道七哥,歡迎大家關注。", "API V1.0", "Terms of service", new Contact("大道七哥", "https://www.cnblogs.com/jstarseven/", "jstarseven@163.com"), "Apache", "http://www.apache.org/", Collections.emptyList()); } }
5、實體類model
package com.dds.sbswagger.model; import io.swagger.annotations.ApiModel; import io.swagger.annotations.ApiModelProperty; import lombok.Data; /** * @author DDS * @date 2019/9/10 13:55 */ @ApiModel("用戶實體") @Data public class User { /** * 用戶Id */ @ApiModelProperty("用戶id") private int id; /** * 用戶名 */ @ApiModelProperty(value = "用戶姓名", example = "zhangdan", required = true) private String name; /** * 用戶地址 */ @ApiModelProperty(value = "用戶地址", example = "北京市海淀區(qū)", required = true) private String address; /** * 用戶手機號 */ @ApiModelProperty(value = "用戶手機號", example = "15689652367", required = true) private String phone; /** * 用戶年齡 */ @ApiModelProperty(value = "用戶年齡", example = "24", required = true) private Integer age; }
6、接口開發(fā)
package com.dds.sbswagger.controller; import com.dds.sbswagger.model.User; import io.swagger.annotations.*; import org.springframework.web.bind.annotation.*; /** * @author DDS * @date 2019/9/10 13:55 */ @RestController @RequestMapping("/user") @Api(tags = "用戶相關接口", description = "提供用戶相關的Rest API") public class UserController { @PostMapping("/add") @ApiOperation(value = "新增用戶接口", notes = "手機號、密碼都是必輸項,年齡隨邊填,但必須是數(shù)字") @ApiImplicitParams({ @ApiImplicitParam(name = "name", value = "用戶名稱", required = true, paramType = "form"), @ApiImplicitParam(name = "address", value = "用戶地址", required = true, paramType = "form"), @ApiImplicitParam(name = "phone", value = "用戶手機號", required = true, paramType = "form"), @ApiImplicitParam(name = "age", value = "用戶年齡", required = true, paramType = "form", dataType = "Integer") }) public boolean addUser(@RequestBody User user) { return false; } @ApiOperation("通過id查找用戶接口") @GetMapping("/find/{id}") public User findById(@PathVariable("id") int id) { return new User(); } @ApiOperation("更新用戶信息接口") @PutMapping("/update") @ApiResponses({ @ApiResponse(code = 400, message = "請求參數(shù)沒填好"), @ApiResponse(code = 404, message = "請求路徑沒有或頁面跳轉路徑不對"), @ApiResponse(code = 405, message = "未知錯誤") }) public boolean update(@RequestBody User user) { return true; } @ApiOperation("刪除用戶接口") @DeleteMapping("/delete/{id}") public boolean delete(@PathVariable("id") int id) { return true; } }
