本文主要講解mall是如何經過整合Swagger-UI來實現一份至關完善的在線API文檔的。html
Swagger-UI是HTML, Javascript, CSS的一個集合,能夠動態地根據註解生成在線API文檔。java
在pom.xml中新增Swagger-UI相關依賴git
<!--Swagger-UI API文檔生產工具-->

注意:Swagger對生成API文檔的範圍有三種不一樣的選擇web

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.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
/** * Swagger2API文檔的配置 */
@Configuration
@EnableSwagger2
public class Swagger2Config {
@Bean
public Docket createRestApi(){
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
//爲當前包下controller生成API文檔
.apis(RequestHandlerSelectors.basePackage("com.macro.mall.tiny.controller"))
//爲有@Api註解的Controller生成API文檔
// .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
//爲有@ApiOperation註解的方法生成API文檔
// .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
.paths(PathSelectors.any())
.build();
}

CommentGenerator爲MyBatis Generator的自定義註釋生成器,修改addFieldComment方法使其生成Swagger的@ApiModelProperty註解來取代原來的方法註釋,添加addJavaFileComment方法,使其能在import中導入@ApiModelProperty,不然須要手動導入該類,在須要生成大量實體類時,是一件很是麻煩的事。數據庫
