背景介绍

使用URLConnection发送POST请求的时候报的这个错误

java.io.IOException: Server returned HTTP response code: 415 for URL: http://localhost:8080/test
	at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1894)
	at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1492)
	at com.weds.datasync.http.HttpTest.testPost(HttpTest.java:84)
	at com.weds.datasync.http.HttpTest.main(HttpTest.java:27)

解决方案

加入这个代码：

            conn.setRequestProperty("content-Type", "application/json; charset=utf-8");
