本文将介绍RESTful API的重磅好伙伴Swagger2，它可以轻松的整合到Spring Boot中，并与Spring MVC程序配合组织出强大RESTful API文档。
它既可以减少我们创建文档的工作量，同时说明内容又整合入实现代码中，让维护文档和修改代码整合为一体，可以让我们在修改代码逻辑的同时方便的修改文档说明。
另外Swagger2也提供了强大的页面测试功能来调试每个RESTful API。
添加Swagger2依赖
在pom.xml中添加Swagger2的依赖
<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.2.2</version></dependency><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.2.2</version></dependency>
创建Swagger2的配置类
在com.qhong包下创建Swagger2类
@Configuration
@EnableSwagger2
public class Swagger2 { @Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.qhong.web"))
.paths(PathSelectors.any())
.build();
} private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("Spring Boot中使用Swagger2构建Restful Api")
.description("更多Spring Boot相关文章请关注：http://www.baidu.com/")
.termsOfServiceUrl("http://www.baidu.com/")
.contact("qhong")
.version("1.0")
.build();
}
}
添加Controller接口
创建com.qhong.domain包，在里面创建User类
public class User {
private Long id;
private String name;
private Integer age;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
}
在com.qhong.web下创建UserController类
@RestController
@RequestMapping(value="/users") public class UserController { static Map<Long, User> users = Collections.synchronizedMap(new HashMap<Long, User>()); @ApiOperation(value="获取用户列表", notes="")
@RequestMapping(value={""}, method= RequestMethod.GET)
public List<User> getUserList() {
List<User> r = new ArrayList<User>(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";
}
}
@ApiOperation
@ApiImplicitParam
@ApiImplicitParams
用于描述创建的api
编译运行：
在HelloController中
@RestController
public class HelloController { //@ApiIgnore
@RequestMapping(value="/hello",method= RequestMethod.GET)
public String Index(){
return "hello world!";
}
}
如果添加@ApiIgnore,该Controller就会被忽略。
