1.swagger配置

/*** Swagger 配置文件*/
@Configuration
public class SwaggerConfig {@Beanpublic Docket createRestApi() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select().apis(RequestHandlerSelectors.basePackage("com.swagger.two")).paths(PathSelectors.any()).build();}private ApiInfo apiInfo() {return new ApiInfoBuilder().title("SpringBoot利用Swagger构建API文档").description("创建人：wjg").termsOfServiceUrl("").version("version 2.0").build();}
}

2.请求路径

 http://localhost:8006/swagger2/swagger-ui.html

3.Swagger2 注解整理

 Api：修饰整个类，描述Controller的作用ApiOperation：描述一个类的一个方法，或者说一个接口ApiParam：单个参数描述ApiModel：用对象来接收参数ApiProperty：用对象接收参数时，描述对象的一个字段ApiResponse：HTTP响应其中1个描述ApiResponses：HTTP响应整体描述ApiIgnore：使用该注解忽略这个APIApiError ：发生错误返回的信息ApiImplicitParam：一个请求参数ApiImplicitParams：多个请求参数 

 4.代码示例

@RestController
@Api(tags = "用户控制层")
public class UserController {// 创建线程安全的Mapstatic Map<Integer, User> users = Collections.synchronizedMap(new HashMap<Integer, User>());/*** 添加用户*/@ApiOperation(value="添加用户", notes="创建新用户")@ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User")@RequestMapping(value = "/addUser", method = RequestMethod.POST)public ResponseEntity<JsonResult> addUser (@RequestBody User user){JsonResult result = new JsonResult();try {users.put(user.getId(), user);result.setResult(user.getId());result.setStatus("ok");} catch (Exception e) {result.setResult("服务异常");result.setStatus("500");e.printStackTrace();}return ResponseEntity.ok(result);}/*** 根据ID查询用户*/@ApiOperation(value="用户查询", notes="根据ID查询用户")@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Integer", paramType = "path")@RequestMapping(value = "/getUserById/{id}", method = RequestMethod.GET)public ResponseEntity<JsonResult> getUserById (@PathVariable(value = "id") Integer id){JsonResult result = new JsonResult();try {User user = users.get(id);result.setResult(user);result.setStatus("200");} catch (Exception e) {result.setResult("服务异常");result.setStatus("500");e.printStackTrace();}return ResponseEntity.ok(result);}/*** 查询用户列表*/@ApiOperation(value="用户列表", notes="查询用户列表")@RequestMapping(value = "/getUserList", method = RequestMethod.GET)public ResponseEntity<JsonResult> getUserList (){JsonResult result = new JsonResult();try {List<User> userList = new ArrayList<>(users.values());result.setResult(userList);result.setStatus("200");} catch (Exception e) {result.setResult("服务异常");result.setStatus("500");e.printStackTrace();}return ResponseEntity.ok(result);}/*** 根据ID修改用户信息*/@ApiOperation(value="更新用户", notes="根据Id更新用户信息")@ApiImplicitParams({@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long",paramType = "path"),@ApiImplicitParam(name = "user", value = "用户对象user", required = true, dataType = "User")})@RequestMapping(value = "/updateById/{id}", method = RequestMethod.PUT)public ResponseEntity<JsonResult> updateById (@PathVariable("id") Integer id, @RequestBody User user){JsonResult result = new JsonResult();try {User user1 = users.get(id);user1.setUsername(user.getUsername());user1.setAge(user.getAge());users.put(id, user1);result.setResult(user1);result.setStatus("ok");} catch (Exception e) {result.setResult("服务异常");result.setStatus("500");e.printStackTrace();}return ResponseEntity.ok(result);}/*** 根据id删除用户*/@ApiOperation(value="删除用户", notes="根据id删除指定用户")@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long", paramType = "path")@RequestMapping(value = "/deleteById/{id}", method = RequestMethod.DELETE)public ResponseEntity<JsonResult> deleteById (@PathVariable(value = "id") Integer id){JsonResult result = new JsonResult();try {users.remove(id);result.setResult(id);result.setStatus("ok");} catch (Exception e) {result.setResult("服务异常");result.setStatus("500");e.printStackTrace();}return ResponseEntity.ok(result);}
