[java] view plain copy  

1：String +ResponseBody = 返回值为String

@RequestMapping("/testResponseBody") @ResponseBody public String testResponseBody(){ return "success"; }
fbb6
[java] view plain copy<span style="font-weight:normal;"><span style="font-size:18px;">alert---success</span></span>  



[java] view plain copy  

2：对象+ResponseBody = json对象

@RequestMapping("/testResponseBody2") @ResponseBody public Student testResponseBody2(){ Student s = new Student(); s.setAge(11); s.setName("11"); return s; }[java] view plain copy  
alert ---{"age":11,"name":"11"}



[java] view plain copy  

3：String +ResponseBody = String

@RequestMapping("/testResponseBody3") @ResponseBody public String testResponseBody3(){ return JSON.toJSONString(SysResult.resultOK()); }alert {"resultcode":0,"resultdesc":""}



字符串可以转换为json对象


[java] view plain copy  

4：void+Response

@RequestMapping("/testResponseBody5") public void testResponseBody5(HttpServletResponse response){ response.setContentType("text/html"); PrintWriter out= null; try { out = response.getWriter(); out.println(JSON.toJSONString(SysResult.resultOK())); out.flush(); out.close(); } catch (IOException e) { e.printStackTrace(); } } {"resultcode":0,"resultdesc":""}
