默認spring cloud使用的HTTP組件為Jersey ,如果不想使用可以從依賴中排除掉,spring cloud基于`RestTemplate`來自動配置客戶端,下面是移除jersey的配置 ``` <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> <exclusions> <exclusion> <groupId>com.sun.jersey</groupId> <artifactId>jersey-client</artifactId> </exclusion> <exclusion> <groupId>com.sun.jersey</groupId> <artifactId>jersey-core</artifactId> </exclusion> <exclusion> <groupId>com.sun.jersey.contribs</groupId> <artifactId>jersey-apache-client4</artifactId> </exclusion> </exclusions> </dependency> ```
