這篇文章主要介紹了關(guān)于swagger配置及踩坑@Api參數(shù)postion無效解決接口排序問題，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教
添加maven依賴
<!-- 集成swagger2 --> <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> <!--google很好用的一個(gè)類庫--> <dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>27.0.1-jre</version> </dependency>
添加配置類

@Configuration
@EnableSwagger2

private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("Hamster接口文檔")

}
}在application.properties中添加配置
