依赖的jar包：

 <dependency>
      <groupId>org.apache.httpcomponents</groupId>
      <artifactId>httpclient</artifactId>
      <version>4.5.3</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/com.alibaba/fastjson -->
    <dependency>
      <groupId>com.alibaba</groupId>
      <artifactId>fastjson</artifactId>
      <version>1.2.41</version>
    </dependency>

代码实现，是否push成功可以在agent的日志中查看。

                System.out.println(EntityUtils.toString(entity));
            }
        }catch (Exception e) {

        }
    }
