springmvc+swagger2

一、swagger2依赖

<!--swagger-->
<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><exclusions><exclusion><artifactId>spring-aop</artifactId><groupId>org.springframework</groupId></exclusion><exclusion><artifactId>jackson-annotations</artifactId><groupId>com.fasterxml.jackson.core</groupId></exclusion></exclusions>
</dependency>
<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId>
</dependency>

二、springmvc配置文件加入

<mvc:default-servlet-handler />

三、web.xml配置

<welcome-file-list><welcome-file>swagger-ui.html</welcome-file>
</welcome-file-list>

四、swagger2配置

　　可创建多个Docket，对restful api进行分组管理

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;@EnableWebMvc
@EnableSwagger2
@Configuration
public class Swagger2Config extends WebMvcConfigurationSupport {@Beanpublic Docket docket() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).groupName("admin").select().apis(RequestHandlerSelectors.withClassAnnotation(Api.class)).apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)).paths(PathSelectors.ant("/**")).build();}//    @Bean
//    public Docket xxx() {
//        return new Docket(DocumentationType.SWAGGER_2)
//                .apiInfo(apiInfo())
//                .groupName("xxx")
//                .select()
//                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
//                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
//                .paths(PathSelectors.ant("/xxx/**"))
//                .build();
//    }private ApiInfo apiInfo() {return new ApiInfoBuilder().title("shiro 无状态组件").contact(new Contact("胡俊哲个", "", "2570230521@qq.com")).version("1.0").build();}
}

五、效果演示

Restful API 访问路径:  * http://IP:port/{context-path}/swagger-ui.html

六、注意事项

　　1、如果有拦截器或者过滤器对项目根路径进行拦截，可能<welcome-file>的配置不生效！

　　2、如果配置 <welcome-file>swagger-ui.html</welcome-file>，访问 http://IP:port/{context-path}/，虽然可以看到页面，但是接口内容显示不出来。原因如下：

　　这个js在匹配url的时候要包含“swagger-ui.html”，所以就出错了。解决方案如下：

　　(1)修改web.xml

 <welcome-file-list><welcome-file>index.html</welcome-file></welcome-file-list>

　　(2)新建index.html

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>首页</title>
</head>
<body>
<script type="application/javascript">window.location.href = window.location.origin + "/shiro/swagger-ui.html";
</script>
</body>
</html>
