在springboot中使用swagger2

1、在springboot中使用swagger的话，首先在pom文件中引入依赖

<!-- 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>
2、创建配置类

@Configuration
@EnableSwagger2
public class Swagger2Config{
  
      @Bean
        public Docket swaggerSpringMvcPlugin(){
        return new Docket(DocunmentationType.Swagger_2).select().apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)).build();
　　}

}

3、在controller类上加Api注解
