- 由于springboot的便捷,以及前后端分離的趨勢,后端和前端配合的橋梁便是接口細節(jié),我們通常遵守REST的原則,為其他開發(fā)人員提供一份REST接口文檔,但后期接口多又雜,手寫十分耗時耗力。因此出現(xiàn)了Swagegr2
Swagger2,
它可以輕松的整合到Spring Boot中,并與Spring MVC程序配合組織出強大RESTful API文檔。它既可以減少我們創(chuàng)建文檔的工作量,同時說明內(nèi)容又整合入實現(xiàn)代碼中,讓維護文檔和修改代碼整合為一體,可以讓我們在修改代碼邏輯的同時方便的修改文檔說明。

創(chuàng)建一個swagger2的配置類
image
@Configuration
@EnableSwagger2
public class Swagger2Config {
@Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("系統(tǒng)Restful API")
.description("系統(tǒng)Restful API描述")
.contact(new Contact("測試", "xxx", "sss"))
.version("1.0")
.build();
}
private ApiInfo apiInfo() {
return new ApiInfo(
"My REST API",
"Some custom description of API.",
"API TOS",
"Terms of service",
new Contact("John Doe", "www.example.com", "myeaddress@company.com"),
"License of API", "API license URL", Collections.emptyList());
}
}
- 兩種apiInfo()寫法都可以
如上代碼所示,通過@Configuration注解,讓Spring來加載該類配置。再通過@EnableSwagger2注解來啟用Swagger2。apiInfo()返回了關于接口界面的自定義信息。例如郵件,協(xié)議信息--Apache 2.0。
添加每個接口的詳細信息
- 我們通過@ApiOperation注解來給API增加說明、通過@ApiImplicitParams、@ApiImplicitParam注解來給參數(shù)增加說明。
@RestController
@RequestMapping(value="/users") // 通過這里配置使下面的映射都在/users下,可去除
public class UserController {
static Map<Long, User> users = Collections.synchronizedMap(new HashMap<Long, User>());
@ApiOperation(value="獲取用戶列表", notes="")
@RequestMapping(value={""}, method=RequestMethod.GET)
public List<User> getUserList() {
List<User> r = new ArrayList<User>(users.values());
return r;
}
@ApiOperation(value="創(chuàng)建用戶", notes="根據(jù)User對象創(chuàng)建用戶")
@ApiImplicitParam(name = "user", value = "用戶詳細實體user", required = true, dataType = "User")
@RequestMapping(value="", method=RequestMethod.POST)
public String postUser(@RequestBody User user) {
users.put(user.getId(), user);
return "success";
}
@ApiOperation(value="獲取用戶詳細信息", notes="根據(jù)url的id來獲取用戶詳細信息")
@ApiImplicitParam(name = "id", value = "用戶ID", required = true, dataType = "Long")
@RequestMapping(value="/{id}", method=RequestMethod.GET)
public User getUser(@PathVariable Long id) {
return users.get(id);
}
@ApiOperation(value="更新用戶詳細信息", notes="根據(jù)url的id來指定更新對象,并根據(jù)傳過來的user信息來更新用戶詳細信息")
@ApiImplicitParams({
@ApiImplicitParam(name = "id", value = "用戶ID", required = true, dataType = "Long"),
@ApiImplicitParam(name = "user", value = "用戶詳細實體user", required = true, dataType = "User")
})
@RequestMapping(value="/{id}", method=RequestMethod.PUT)
public String putUser(@PathVariable Long id, @RequestBody User user) {
User u = users.get(id);
u.setName(user.getName());
u.setAge(user.getAge());
users.put(id, u);
return "success";
}
@ApiOperation(value="刪除用戶", notes="根據(jù)url的id來指定刪除對象")
@ApiImplicitParam(name = "id", value = "用戶ID", required = true, dataType = "Long")
@RequestMapping(value="/{id}", method=RequestMethod.DELETE)
public String deleteUser(@PathVariable Long id) {
users.remove(id);
return "success";
}
}
這時啟動springboot,訪問http://localhost:8080/your-app-root/swagger-ui.html
demo有些簡單,希望大神輕噴
