其他不多說了，直接上步驟。

1、引入包

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.6.1</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.6.1</version>
</dependency>

2、配置類

/**
 * <p>Title: Swagger配置類<／p>
 * <p>Description: <／p>
 * @author swy
 * @date 2017年10月10日
 * @version 1.0
 */
@EnableWebMvc
@EnableSwagger2
@ComponentScan(basePackages = {"com.intetex.controller"})
@Configuration
public class SwaggerConfig {

@Bean
    public Docket createDocket() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .groupName("admin")
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.intetex.controller")) // 注意修改此處的包名
                .paths(PathSelectors.any())
                .build();
    }


    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
        .title("INTETEX ADMIN RESTful APIs")
        .description("兄弟紡織網  後臺管理 RESTful APIs")
        .termsOfServiceUrl("http://www.intetex.com/")
        //.contact("程式猿DD")
                .version("1.1.0")
                .build();
    }
}

3、註冊配置

<bean class="com.intetex.swagger.SwaggerConfig"/>

4、配置靜態資源

<mvc:resources mapping="swagger-ui.html" location="classpath:/META-INF/resources/"/>
    <mvc:resources mapping="/webjars/**" location="classpath:/META-INF/resources/webjars/"/>

5、配置web.xml

  <servlet>
    <description>spring mvc servlet</description>
    <servlet-name>springMvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springMvc</servlet-name>
    <url-pattern>*.shtml</url-pattern>
    <url-pattern>/swagger-resources</url-pattern>
    <url-pattern>/swagger-resources/configuration/ui</url-pattern>
    <url-pattern>/swagger-resources/configuration/security</url-pattern>
    <url-pattern>/v2/api-docs</url-pattern>
  </servlet-mapping>
