## 说明 ##

Swagger 基础示例。

使用 springfox 框架。

## 依赖 ##

<dependency>
    			<groupId>io.swagger</groupId>
    			<artifactId>swagger-annotations</artifactId>
    			<version>1.5.21</version>
    		</dependency>
    		<dependency>
    			<groupId>io.swagger</groupId>
    			<artifactId>swagger-models</artifactId>
    			<version>1.5.21</version>
    		</dependency>
    		
    		<dependency>
    			<groupId>io.springfox</groupId>
    			<artifactId>springfox-swagger2</artifactId>
    			<version>2.9.2</version>
    		</dependency>
    		<dependency>
    			<groupId>io.springfox</groupId>
    			<artifactId>springfox-swagger-ui</artifactId>
    			<version>2.9.2</version>
    		</dependency>

## 配置 application.properties ##

# 指定路径匹配规则。如果不指定，则Springfox和SpringBoot默认路径匹配规则冲突，会报错。
    spring.mvc.pathmatch.matching-strategy=ANT_PATH_MATCHER

## 配置 SwaggerConfig ##

package com.example.swaggerdemo.config;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    import springfox.documentation.builders.ApiInfoBuilder;
    import springfox.documentation.builders.PathSelectors;
    import springfox.documentation.builders.RequestHandlerSelectors;
    import springfox.documentation.service.ApiInfo;
    import springfox.documentation.spi.DocumentationType;
    import springfox.documentation.spring.web.plugins.Docket;
    import springfox.documentation.swagger2.annotations.EnableSwagger2;
    
    @Configuration
    @EnableSwagger2
    public class SwaggerConfig {
    	@Bean
    	Docket createRestApi() {
    		return new Docket(DocumentationType.SWAGGER_2) // DocumentationType.SWAGGER_2 固定的，代表swagger2
    //                .groupName("分布式任务系统") // 如果配置多个文档的时候，那么需要配置groupName来分组标识
    				.apiInfo(apiInfo()) // 用于生成API信息
    				.select() // select()函数返回一个ApiSelectorBuilder实例,用来控制接口被swagger做成文档
    				.apis(RequestHandlerSelectors.basePackage("com.example.swaggerdemo")) // 用于指定扫描哪个包下的接口
    				.paths(PathSelectors.any())// 选择所有的API,如果你想只为部分API生成文档，可以配置这里
    				.build();
    	}
    
    	/**
    	 * 用于定义API主界面的信息，比如可以声明所有的API的总标题、描述、版本
    	 * 
    	 * @return
    	 */
    	private ApiInfo apiInfo() {
    		return new ApiInfoBuilder().title("XX项目API") // 可以用来自定义API的主标题
    				.description("XX项目SwaggerAPI管理") // 可以用来描述整体的API
    				.termsOfServiceUrl("") // 用于定义服务的域名
    				.version("1.0") // 可以用来定义版本。
    				.build(); //
    	}
    }
