## 1.添加依赖: ##

在pom中添加swagger的依赖,这里使用的swagger版本为2.7.0,springboot相应版本为2.0.3,jdk1.8  
示例如下:

<swagger.version>2.7.0</swagger.version>
    
    		<dependency>
    			<groupId>io.springfox</groupId>
    			<artifactId>springfox-swagger2</artifactId>
    			<version>${swagger.version}</version>
    		</dependency>
    		<dependency>
    			<groupId>io.springfox</groupId>
    			<artifactId>springfox-swagger-ui</artifactId>
    			<version>${swagger.version}</version>
    		</dependency>

## 2.注入Bean: ##

示例如下:

import io.swagger.annotations.ApiOperation;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
    import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
    import springfox.documentation.builders.ApiInfoBuilder;
    import springfox.documentation.builders.PathSelectors;
    import springfox.documentation.builders.RequestHandlerSelectors;
    import springfox.documentation.service.ApiInfo;
    import springfox.documentation.service.ApiKey;
    import springfox.documentation.spi.DocumentationType;
    import springfox.documentation.spring.web.plugins.Docket;
    import springfox.documentation.swagger2.annotations.EnableSwagger2;
    
    import java.util.List;
    
    import static com.google.common.collect.Lists.newArrayList;
    
    @Configuration
    @EnableSwagger2
    public class SwaggerConfig implements WebMvcConfigurer { 
    
    	@Override
    	public void addResourceHandlers(ResourceHandlerRegistry registry) { 
    		registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
    		registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
    		registry.addResourceHandler("/swagger/**").addResourceLocations("classpath:/static/swagger/");
    	}
    
    	@Bean
    	public Docket createRestApi() { 
    		return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()
    				// 加了ApiOperation注解的类，才生成接口文档
    				.apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
    				// 包下的类，才生成接口文档
    				// .apis(RequestHandlerSelectors.basePackage("cn.sd.controller"))
    				.paths(PathSelectors.any()).build().securitySchemes(security());
    	}
    
    	private ApiInfo apiInfo() { 
    		return new ApiInfoBuilder().title("敢达抽奖接口文档").description("敢达抽奖接口文档").version("2.1").build();
    	}
    
    	private List<ApiKey> security() { 
    		return newArrayList(new ApiKey("token", "token", "header"));
    	}
    
    }

## 3.使用: ##

之前在config里设置扫描的规则,所以在controller层方法上方添加对应信息即可自动生成文档  
示例1(正常获取参数):

/** * 列表 */
    	@RequestMapping("/drawRecordList")
    	@ApiOperation(value = "查看个人抽奖记录", tags = "抽奖管理", httpMethod = "GET")
    	public R getDrawRecordList(@RequestParam(required = true) String openId) { 
    		return R.ok().put("drawRecordList", drawRecordService.getDrawRecordList(openId));
    	}

示例2(通过map获取参数):

@ApiOperation(value = "查看抽奖记录", tags = "后台管理", httpMethod = "GET")
    	@GetMapping("/drawRecord")
    	@ApiImplicitParams({  @ApiImplicitParam(name = "limit", value = "每页显示条数", paramType = "query", dataType = "Int"),
    			@ApiImplicitParam(name = "page", value = "检索页", paramType = "query", dataType = "Int"),
    			@ApiImplicitParam(name = "lid", value = "lid", paramType = "query", dataType = "String"),
    			@ApiImplicitParam(name = "roleId", value = "角色ID", paramType = "query", dataType = "String"),
    			@ApiImplicitParam(name = "startTime", value = "开始时间", paramType = "query", dataType = "String"),
    			@ApiImplicitParam(name = "endTime", value = "结束时间", paramType = "query", dataType = "String"),
    			@ApiImplicitParam(name = "timestamp", value = "时间戳", paramType = "query", dataType = "Long"),
    			@ApiImplicitParam(name = "sign", value = "签名", paramType = "query", dataType = "String") })
    	R drawRecord(@ApiParam(hidden = true) @RequestParam Map<String, Object> params) { 
    		adminService.check(Long.valueOf((String) params.get("timestamp")), (String) params.get("sign"));
    		PageUtils page = adminService.getDrawRecord(params);
    		return new R().put("page", page);
    	}

## 4.生成的接口文档地址: ##

示例如下:  
[http://localhost:8082/sds\_admin/swagger-ui.html][http_localhost_8082_sds_admin_swagger-ui.html]  
项目启动的地址/swagger-ui.html即可

## 5.注解属性值含义: ##

### @ApiOperation: ###

value:该接口名称  
tags:接口所属类别  
httpMethod:接口被调用的方法

### @ApiImplicitParam ###

name 传入参数名  
value 该参数代表含义  
paramType 该参数传输方式  
dataType 该参数数据类型

### @ApiParam ###

hidden是否在swagger里隐藏该参数

## 6.生成示例及调用 ##

示例1:  
!\[!\[\]([https://img-blog.csdnimg.cn/20181220184838893.png?x-oss-process=image/watermark,type\_ZmFuZ3poZW5naGVpdGk,shadow\_10,text\_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI0NTE2NTQ5,size\_16,color\_FFFFFF,t\_70][https_img-blog.csdnimg.cn_20181220184838893.png_x-oss-process_image_watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI0NTE2NTQ5_size_16_color_FFFFFF_t_70])  
示例2:  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI0NTE2NTQ5_size_16_color_FFFFFF_t_70]

## 7.如何在swagger里传输herad ##

在config中我们添加了如下配置,

private List<ApiKey> security() { 
            return newArrayList(
                new ApiKey("token", "token", "header")
            );
        }

其含义是可以设置swagger在发送请求是在header中传输参数名为token的参数,该参数释义即为token,示例如下:  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI0NTE2NTQ5_size_16_color_FFFFFF_t_70 1]  
在右上角点击Authorize,在弹出窗口内输入token对应的value值,再点击Authorize即可在接下来的请求中都携带该header值  
注意,刷新页面后需要重新设置token值。
