大家好，又见面了，我是你们的朋友全栈君。

package com.chj.cms.controller;

import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.kafka.core.KafkaTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.chj.cms.domain.Users;

@Controller
@RequestMapping(“/admin”)
public class TestController {

@Autowired
private KafkaTemplate<Integer, String> kafkaTemplate;


@RequestMapping("/saveLiuyan")
@ResponseBody
public Map<String,Boolean> save(HttpServletRequest request,Integer fid,String content) {
	Map<String,Boolean> map = new HashMap<>();
	//留言
	Users user = (Users)request.getSession().getAttribute("user");
	
	Integer uid = user.getId();
	
	String message=uid+","+fid+","+content;
	
	kafkaTemplate.sendDefault(message);		
	map.put("flag", true);
	return map ;
}
