spring boot怎么直接返回字符串了

Answer 1

前台页面：function ajaxPost(){$.ajax({data:{"name":$("#name").val(),"age":$("#age").val(),"sex":$("input[name='sex']:checked").val()},type:"Post",async:false, //加上这个属性就好了dataType: 'json',url:"addStudent.jsp",error:function(data){alert('添加失败！');},success:function(data){alert('添加成功！');window.location.href = 'list.jsp'}});}
