Java使用FeignClient发送HTTP 请求

使用FeignClient发送HTTP请求
1.添加依赖
<!-- 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.发送接口

@FeignClient(name = "**ServiceClient", url = "${url.signerUrl}" )
public interface **ServiceClient {
    @RequestMapping(value = "/***", method = RequestMethod.POST)
    public String ***(@RequestBody(required = true) String param);
}
3.调用接口发送数据
