本文介绍了一个处理UTF-8编码的JSON请求的例子，包括客户端如何发送POST请求及服务端如何读取并解析该请求的具体实现。通过示例代码展示了如何确保字符集的一致性，避免乱码问题。

参考代码如下：

final_request.setCharacterEncoding("UTF-8");
  StringBuilder buffer = new StringBuilder();
  BufferedReader reader=null;
  try{
   reader = new BufferedReader(new InputStreamReader(final_request.getInputStream(),"UTF-8"));
   String line=null;
   while((line = reader.readLine())!=null){
    buffer.append(line);
         }
  }catch(Exception e){
   e.printStackTrace();
  }finally{
   if(null!=reader){
    try {
     reader.close();
    } catch (IOException e) {
     e.printStackTrace();
    }
   }
  }
buffer.toString()

自己代码如下，亲测没有问题

接口客户端请求输入：

http://10.11.100.250:9999/MVC/down/WebInterfaceTempletDown.dx

POST方式：Content-Type:application/json;charset=UTF-8

传入的json

{
"monId":"20191229135102184",
"groupId":"004",
"proberId":"03",
"title":"TTTTTT",
"monType":"c01-job-running-error"

}

服务端：

public ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {
System.out.println("into webinterface down gate");
//request.setCharacterEncoding("GBK");
request.setCharacterEncoding("UTF-8");

StringBuffer str = new StringBuffer();
try {
//BufferedInputStream in = new BufferedInputStream(request.getInputStream());
InputStreamReader in = new InputStreamReader(request.getInputStream(),"UTF-8");
int i;
char c;
while ((i=in.read())!=-1) {
c=(char)i;
str.append(c);
}
}catch (Exception ex) {
ex.printStackTrace();
}

JSONObject obj= JSONObject.fromObject(str.toString());
System.out.println(obj.get("operUser"));
