前端实现：

var student = {"name":1,"age":2,"score":3
};
$.ajax({                                url:"student/test/delStudentByPrimaryKey.action",contentType:"application/json;charset=UTF-8",type:'POST',dataType:'json',//json 返回值类型data: JSON.stringify(student),//转化为json字符串success:function(data){}
});

后端实现：

@RequestMapping(value = "/delStudentByPrimaryKey")
void deleteByPrimaryKey(@RequestBody Student student){System.out.println(student);
}
