整合项目遇到的一些问题 记录一下 前后台传值 和 编码问题

前台拿值到后台：

后台 controller：

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;

public class SendMessageAll {
    
    @Autowired
    private SystemService systemService;
    
    // 调用方法： href=/yh/sendMessageAllController.do?syncUser
    @RequestMapping(params="syncUser")
    public void syncUser(HttpServletRequest request,
              HttpServletResponse response,Long user) {
        
        //DataSourceContextHolder.setDataSourceType(DataSourceType.dataSource4); // 更改设置数据源
        
        //List<Map<String, Object>> list =findForJdbc("select * from userlist", "userlist");
        //System.out.println(1);
         //String seqId= request.getParameter("user");
         String content = request.getParameter("contentTd");
         
         System.out.println(content);
         
         TSUser toUser = systemService.findUniqueByProperty(TSUser.class, "seqId", user);
         String seqid= toUser.getUserId();
         
        String lujing = "//2560P-PC/ServerMsgList/111.sisenmsg";
          File file = new File(lujing);
          if (!file.getParentFile().exists()) {
           file.getParentFile().mkdirs();
          }
          try {
           file.createNewFile();
          } catch (IOException e) {
           e.printStackTrace();
          }

          try {
              OutputStreamWriter bw = new OutputStreamWriter(
                      new FileOutputStream(file),"UTF-8");
           
           String a1="True";        //True/False(模拟用户/系统消息)
           String a2="haha";            //发送人编号(系统消息时可为空)
           String a3="hehe";            //接收人编号(向所有人发送时可为空)
           String a4="False";        //True/False(向所有人发送/向单一用户发送)
           String a5="hello 世界！";        //消息正文
           bw.write(a1+"
"
                    +a2+"
"
                       +seqid+"

                       +a4+"
"
                       + content);
           bw.flush();
           bw.close();
           bw.close();
          } catch (IOException e) {
           e.printStackTrace();
          }
          try {
           FileReader fr = new FileReader(file);
           BufferedReader bReader = new BufferedReader(fr);
           String string = bReader.readLine();
           System.out.println(string);
           fr.close();
           bReader.close();
           

          } catch (FileNotFoundException e) {
           e.printStackTrace();
          } catch (IOException e) {
           e.printStackTrace();
          }
        
        
    }
}

前台主要js

function sendmessage(){

var psnNo = document.getElementById("contentTd").value;

alert(psnNo);
//alert(user);
alert(jQuery("#smsBodyInfoForm").serialize());
//var url = "<%=contextPath%>/com.buss/sisenmess/service/impl/SmsSyncImpl/syncUser.act?seqId="+seqId;
var url = "<%=contextPath%>/sendMessageAllController.do?syncUser";

jQuery.post(url,jQuery("#smsBodyInfoForm").serialize(), function(res) {

});
}

向文件写入

String lujing = "//2560P-PC/ServerMsgList/111.sisenmsg";//文件地址
File file = new File(lujing);

OutputStreamWriter bw = new OutputStreamWriter(

new FileOutputStream(file),"UTF-8");

 从后台拿值到前台
