前言:
swagger2就相当于一个实时同步文档,给前端提供接口的插件。将平常写注释前面加个注解就可以了,非常的方便,但是生产环境为了安全和运行效率,需要关闭(抄自知乎)
1.引入依赖
可在全局引入,如:api
代码语言:javascript复制 <!-- swagger -->
<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>
2.添加配置类
在config包下,新加Swagger2
代码语言:javascript复制package com.zb.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;
/**
* @author zh
* @ClassName cn.saytime.Swgger2
* @Description
* @date 2017-07-10 22:12:31
*/
@Configuration
public class Swagger2 {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.zb.controller"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("springboot利用swagger构建api文档")
.description("简单优雅的restfun风格")
.termsOfServiceUrl("#")
.version("1.0")
.build();
}
}
3.控制器使用注解
ApiOperation的,代表该方法名 (value=名字1,notes=名字2)
ApiImplicitParam的,代表参数名 (name=参数名,value=参数介绍,paramType=接受参数方式,dataType=参数类型)
参照图&代码:
代码语言:javascript复制 @ApiOperation(value = "商品详情", notes = "商品详情-notes")
@ApiImplicitParam(name = "skuId", value = "商品编号", required = true, paramType = "path", dataType = "string")
paramType 对照表:
paramType = “path” | paramType = “query” | paramType = “body” | paramType = “header” |
---|---|---|---|
@PathVariable(“skuId”) | @RequestParam(“skuId”) | @RequestBody | @RequestHeader |
@GetMapping(“/info/{skuId}”) | 无需加 | 无需加 | 无需加 |
多个参数:
代码语言:javascript复制 @ApiOperation(value = "修改商品", notes = "修改商品-notes")
@ApiImplicitParams({
@ApiImplicitParam(name = "skuId", value = "商品编号", required = true, paramType = "query", dataType = "string"),
@ApiImplicitParam(name = "skuDto", value = "商品对象", required = true, paramType = "body", dataType = "SkuDto")
})
4.实体类使用注解
如果有dto,内部的实体类就不用注解
参数介绍: ApiModel: (value=类名字,description=类介绍)
ApiModelProperty: (value=参数介绍)
代码语言:javascript复制@ApiModel(value = "OrderItemDto", description = "")
@ApiModelProperty(value = "这个是ID")
5.启动
启动类添加
代码语言:javascript复制@EnableSwagger2
程序启动完后,浏览器打开:http://localhost:端口号/swagger-ui.html
