添加pom依赖:
io.springfox
springfox-swagger2
2.2.2
io.springfox
springfox-swagger-ui
2.2.2
创建Swagger2配置类:
在Application.java同级创建Swagger2的配置类Swagger2。
@Configuration
@EnableSwagger2
public class Swagger2 {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.sboot.web"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("My RESTful APIs")
.description("用Swagger2构建RESTful APIs")
.termsOfServiceUrl("yourUrl")
.contact("zzhblh")
.version("1.0")
.build();
}
}
如上代码所示,通过@Configuration注解,让Spring来加载该类配置。再通过@EnableSwagger2注解来启用Swagger2。
再通过createRestApi函数创建Docket的Bean之后,apiInfo()用来创建该Api的基本信息(这些基本信息会展现在文档页面中)。select()函数返回一个ApiSelectorBuilder实例用来控制哪些接口暴露给Swagger来展现,本例采用指定扫描的包路径来定义,Swagger会扫描该包下所有Controller定义的API,并产生文档内容(除了被@ApiIgnore指定的请求)。
Controller:
通过@ApiOperation注解来给API增加说明、通过@ApiImplicitParams
,@ApiImplicitParam注解来给参数增加说明。
@RestController
@RequestMapping(value="/users") // 通过这里配置使下面的映射都在/users下,可去除
public class UserController {
static Map users = Collections.synchronizedMap(new HashMap());
@ApiOperation(value="获取用户列表", notes="")
@RequestMapping(value={""}, method=RequestMethod.GET)
public List getUserList() {
List r = new ArrayList(users.values());
return r;
}
@ApiOperation(value="创建用户", notes="根据User对象创建用户")
@ApiImplicitParam(name = "user", value = "用户详细实体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="获取用户详细信息", notes="根据url的id来获取用户详细信息")
@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")
@RequestMapping(value="/{id}", method=RequestMethod.GET)
public User getUser(@PathVariable Long id) {
return users.get(id);
}
@ApiOperation(value="更新用户详细信息", notes="根据url的id来指定更新对象,并根据传过来的user信息来更新用户详细信息")
@ApiImplicitParams({
@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long"),
@ApiImplicitParam(name = "user", value = "用户详细实体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="删除用户", notes="根据url的id来指定删除对象")
@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")
@RequestMapping(value="/{id}", method=RequestMethod.DELETE)
public String deleteUser(@PathVariable Long id) {
users.remove(id);
return "success";
}
}
