Answer 1

@Test
public void post(){
//创建默认的Httpclient实例
CloseableHttpClient httpclient = HttpClients.createDefault();
//创建post请求
HttpPost post = new HttpPost("你的controller地址");
//创建参数队列
List params = new ArrayList<>();
params.add(new BasicNameValuePair("name", "value"));
UrlEncodedFormEntity entity;
try {
//设置参数的编码方式
entity = new UrlEncodedFormEntity(params,"UTF-8");
post.setEntity(entity);
System.out.println("url:"+post.getURI());
try {
// 执行post请求
CloseableHttpResponse response = httpclient.execute(post);
//获取响应实体
HttpEntity etity = response.getEntity();
if(etity != null){
System.out.println("--------------------------------------");
//打印响应内容
System.out.println("Response content: " + EntityUtils.toString(entity, "UTF-8"));

System.out.println("--------------------------------------");

}
response.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
httpclient.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
