概念:
构建RESTful API的目的通常是由于多终端的原因,这些终端会共用很多底层业务逻辑,因此会抽象出来一层同时服务于多个移动端或Web前端。
SpringBoot 整合Swagger2,并配合Spring MVC组织处强大的Restful Api 文档。
步骤:
1、pom.xml新增依赖包:
<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>
2、创建配置类swagger2:
@Configuration @EnableSwagger2 public class Swagger2 { @Bean public Docket createRestApi() { return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()) .select() .apis(RequestHandlerSelectors.basePackage("per.yhq.controller.Swagger2")) .paths(PathSelectors.any()) .build(); } private ApiInfo apiInfo() { return new ApiInfoBuilder() .title("Swagger首页的标题") .description("Swagger首页的标题下的描述") .termsOfServiceUrl("https://www.cnblogs.com/yaohuiqin/p/9367822.html") .contact("yaohuiqin") .version("1.0") .build(); }
分析: @Configuration (Spring将这个类解析成配置类)
@EnableSwagger2(启用Swagger)
5、添加controller类,以及entity实体类:
@RestController @RequestMapping(value = "/users") public class SwaggerUserController { static Map<Long,User> users = Collections.synchronizedMap(new HashMap<Long, User>()); public SwaggerUserController(){ users.put(123L,new User(1307L,"yhq",25)); } @ApiOperation(value="获取用户列表", notes="获取全部的用户信息") @RequestMapping(value = {""} ,method = RequestMethod.GET) public List<User> getUserList(){ List<User> userlist = new ArrayList<User>(users.values()); return userlist; } @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.getUserId(), 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", paramType = "path") @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", paramType = "path"), @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", paramType = "path") @RequestMapping(value="/{id}", method=RequestMethod.DELETE) public String deleteUser(@PathVariable Long id) { users.remove(id); return "success"; } }
public class User { private Long userId; private String name; private int age; //.....get set 方法,构造器等 }
4、运行项目,在浏览器上访问:http://localhost:8080/swagger-ui.html
输入参数,点击Try it out,可以进行测试。
