springboot集成swagger2

swagger2有哪些注解

作用范围	API	使用位置
对象属性	@ApiModelProperty	用在出入参数对象的字段上
协议集描述	@Api	用于controller类上
协议描述	@ApiOperation	用在controller的方法上
Response集	@ApiResponses	用在controller的方法上
Response	@ApiResponse	用在 @ApiResponses里边
非对象参数集	@ApiImplicitParams	用在controller的方法上
非对象参数描述	@ApiImplicitParam	用在@ApiImplicitParams的方法里边
描述返回对象的意义	@ApiModel	用在返回对象类上

注解的使用

@ApiModelProperty-----------------------------name：属性名 value：属性描述

1 @ApiModelProperty(name = "userNo",value = "用户编号")
2  private int userNo; //用户编号

View Code

@ApiModel---------------------------------------description ：model对象描述

1 @ApiModel(description = "用户信息")
2 public class User {}

View Code

@ApiOperation

 1  @RequestMapping(value = "addUserForPost",method = RequestMethod.POST,headers = "Content-Type=application/x-www-form-urlencoded")
 2     @ApiOperation(value = "表单形式添加用户")
 3  public Map addUser(HttpServletRequest request,String userName, Integer userAge){
 4 
 5         Enumeration<String> names = request.getHeaderNames();
 6         while (names.hasMoreElements()){
 7             String name = names.nextElement();
 8 
 9             System.out.println(name+"==="+request.getHeader(name));
10         }
11         System.out.println("userName="+userName+",userAge="+userAge);
12         RESPONSE.put("code",200);
13         RESPONSE.put("msg","添加成功");
14 
15         return RESPONSE;
16     }

View Code

@Api

1 @RestController
2 @Api(tags = "UserController | 测试swagger注解的控制器")
3 @RequestMapping(value = "/user")
4 public class UserController {}

View Code

@ApiImplicitParams 和@ApiImplicitParam组合使用

 1   @RequestMapping(value = "/getUser",method = RequestMethod.GET)
 2     @ApiOperation(value = "获取用户信息")
 3     @ApiImplicitParams({
 4             @ApiImplicitParam(name = "id",value = "用户编号",paramType = "query"),
 5             @ApiImplicitParam(name = "name",value = "用户名称",paramType = "query")
 6     })
 7     public User getUser(@RequestParam(required = false) int id,@RequestParam(required = false) String name){
 8         User user = new User();
 9         user.setUserNo(id);
10         user.setAge(12);
11         user.setUserName("lisi");
12         return user;
13     }

View Code

@ApiImplicitParam属性值说明

name：属性值

value：属性描述

paramtype：参数类型

paramtype：　　

　　　　a、path---------请求参数放在请求路径上 /a/{id}，get请求

 1  @RequestMapping(value = "/modifyUser/{userNo}",method = RequestMethod.GET)
 2     @ApiOperation("修改用户信息")
 3     @ApiImplicitParams({
 4             @ApiImplicitParam(name = "userNo",value = "用户编号",paramType = "path")
 5     })
 6     public Map updUser(@PathVariable(required = true) int userNo){
 7         Map map = new HashMap();
 8         map.put("code",200);
 9         map.put("msg","修改成功");
10         return map;
11     }

View Code

 2     @ApiOperation(value = "表单形式添加用户")
 3     @ApiImplicitParams({
 4             @ApiImplicitParam(name = "userName",value = "用户名称",paramType = "form",required = true),
 5             @ApiImplicitParam(name = "userAge",value = "用户年龄",paramType = "form",required = true)
 6     })
 7     public Map addUser(HttpServletRequest request,String userName, Integer userAge){
 8 
 9         Enumeration<String> names = request.getHeaderNames();
10         while (names.hasMoreElements()){
11             String name = names.nextElement();
12 
13             System.out.println(name+"==="+request.getHeader(name));
14         }
15         System.out.println("userName="+userName+",userAge="+userAge);
16         RESPONSE.put("code",200);
17         RESPONSE.put("msg","添加成功");
18 
19         return RESPONSE;
20     }

　　　　d、body -----------请求参数在流里，即请求参数以json格式传递，post请求

 3     @ApiImplicitParams({
 4             @ApiImplicitParam(name = "user",value = "用户信息",dataType = "User",paramType = "body"),
 5     })
 6     public Map addUser(@RequestBody User user){

springboot如何与swagger2集成

<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.9.2</version>
</dependency>


<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.9.2</version>
</dependency>

　　1、在启动类上加上@EnableSwagger2注解

　　2、自定义一个swagger2配置类

 1 @Configuration
 2 public class Sawgger2 {
 3 
 4     @Bean
 5     public Docket createRestApi(){
 6 
 7         return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).
 8                 select().apis(RequestHandlerSelectors.basePackage("com.swagger.springbootswagger.controller"))
 9                 .paths(PathSelectors.any()).build();
10     }
11 
12     @Bean
13     public ApiInfo apiInfo(){
14         return new ApiInfoBuilder().title("Spring boot中使用Swagger2构建RESTful APIs").version("1.0").build();
15     }
16 }

View Code

3、配置是否开启swagger

　　配置文件自定义一个属性

　　　　spring.swagger2.enabled=true

　　在swagger配置类上加上 @ConditionalOnProperty(name = "spring.swagger2.enabled",havingValue = "true")注解

　　4、对swagger页面进行增强

　　　　1）maven引入如下jar包

<!-- swagger2 增强UI ,拥有好看的界面, 和接口分组,排序等功能,如不引用可自行删除-->
        <dependency>
            <groupId>com.github.xiaoymin</groupId>
            <artifactId>swagger-bootstrap-ui</artifactId>
            <version>1.8.7</version>
        </dependency>

　　　　2）swagger配置类上加上 @EnableSwaggerBootstrapUI 注解

3）访问页面由swagger-ui.html变成doc.html

　　　　　　 http://localhost:8081/doc.html
