部署过程
1.导入依赖
修改pom.xml,在其中加入以下依赖;
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.4.0</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.4.0</version>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.47</version>
</dependency>
2.创建controller层、实体类
因为只是简单的demo,而swagger只注重controller层的请求与响应,因此本文中午service层与dao层。
实体类:
public class User {
private int id;
private String name;
public User(String name) {
this.name = name;
}
public User(int id, String name) {
this.id = id;
this.name = name;
}
public User() {
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
}
controller:
@RestController
@RequestMapping("/user")
public class UserController {
@RequestMapping(value = "/{name}",method = RequestMethod.POST)
public JSONObject insert(@PathVariable("name") String name)
{
JSONObject jsonObject = new JSONObject();
jsonObject.put("status",200);
jsonObject.put("msg","insert");
return jsonObject;
}
@RequestMapping(value = "/{id}",method = RequestMethod.DELETE)
public JSONObject delete(@PathVariable("id") int id)
{
JSONObject jsonObject = new JSONObject();
jsonObject.put("status",200);
jsonObject.put("msg","delete "+id);
return jsonObject;
}
@RequestMapping(value = "/{id}/{name}",method = RequestMethod.PUT)
public JSONObject update(@PathVariable("id") int id,@PathVariable("name") String name)
{
JSONObject jsonObject = new JSONObject();
jsonObject.put("status",200);
jsonObject.put("msg","update");
return jsonObject;
}
@RequestMapping(value = "/{id}",method = RequestMethod.GET)
public JSONObject get(@PathVariable("id") int id)
{
JSONObject jsonObject = new JSONObject();
jsonObject.put("status",200);
jsonObject.put("msg","get");
return jsonObject;
}
}
3.创建swagger配置文件
在项目的启动类的同级文件建立swagger的配置文件
@Configuration
@EnableSwagger2
public class Swagger2 {
//swagger2的配置文件,这里可以配置swagger2的一些基本的内容,比如扫描的包等等
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
//为当前包路径
.apis(RequestHandlerSelectors.basePackage("com.example.demo.controller"))
.paths(PathSelectors.any())
.build();
}
/**
*
*@Author
*@Description
*@Date
*
*/
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
//页面标题
.title("Spring Boot 测试使用 Swagger2 构建RESTful API")
//创建人
.contact(new Contact("wyp", "QQ.com", "Wypeng19971214@163.com"))
//版本号
.version("1.0")
//描述
.description("API 描述")
.build();
}
}
4.修改application.yml【作用等价于application.properties】
spring:
mvc:
static-path-pattern: /**
resources:
static-locations: classpath:/META-INF/resources/
打开浏览器,输入http://localhost:8080/swagger-ui.html,就可以看到效果了。
常用注解效果演示
swagger中常用的注解有
@Api 注解在controller类上 @ApiModel 注解在类上,一般是实体类 @ApiOperation 注解在方法上,表明方法级解释 @ApiImplicitParams 注解在方法上,一般与@ApiImplicitParam共用,多个参数逗号隔开,表请求参数 @ApiResponses 注解在方法上表响应,一般与@ApiResponse公用
@API
@ApiOperation
