SpringMvc直接接收json数据自动转化为Map的实例

$.ajax({ 
 type : "POST", 
 url : "/search", 
 data :JSON.stringify(searchData), 
 contentType:"application/json",
 dataType : "json", 
 success : function(data) { } 
});

@RequestMapping(value = "/search",method = RequestMethod.POST)
public void search (@RequestBody Map<String,String> map){
 System.out.println("传进来的参数：" + map);
}
