Java使用FeignClient發送HTTP 請求

使用FeignClient發送HTTP請求
1.添加依賴
<!-- spring cloud jar-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    <version>2.1.0.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-openfeign</artifactId>
    <version>2.1.0.RELEASE</version>
</dependency>

2.發送接口

@FeignClient(name = "**ServiceClient", url = "${url.signerUrl}" )
public interface **ServiceClient {

    @RequestMapping(value = "/***", method = RequestMethod.POST)
    public String ***(@RequestBody(required = true) String param);

}

3.調用接口發送數據
