Java - 如何使用邮递员插入数据

Question

我的代码运行完美，但在邮递员方面显示错误

“此请求标识的资源只能根据请求”接受“标题生成具有不可接受特征的响应。”

发布的数据也来自restController，serviceImpl和Studentimpl。

我的restController是

        @RequestMapping(value="save",method=RequestMethod.POST,produces="application/json")

        GetStudentSaveResponse saveResponse(@RequestBody GetStudentSaveRequest saveRequest)
        {
            System.out.println(saveRequest.getName());
            System.out.println(saveRequest.getAddress());
            return serviceIntf.saveResponse(saveRequest);
        }
         RestImpl is
         @Override
        public GetStudentSaveResponse saveResponse(GetStudentSaveRequest saveRequest) {
                GetStudentSaveResponse saveResponse = new GetStudentSaveResponse();
                studentIntf.SaveStudent(saveRequest.getName(), saveRequest.getAddress());           
                System.out.println("SERVICE"+saveRequest.getName());
                return saveResponse;
            }

实现类是：

public void SaveStudent(String name, String address) {
    try
    {
        java.sql.Date date = new java.sql.Date(new java.util.Date().getTime());
        con=jdbctemplate.getDataSource().getConnection();

        CallableStatement call = con.prepareCall("{Student_pro(?,?,?,?,?)}");
        call.setString(1, "insertStudent");
        call.setInt(2, 0);
        call.setString(3, name);
        call.setString(4, address);
        call.setDate(5, date);

        System.out.println(name);
        System.out.println(address);

    }catch(Exception e){e.printStackTrace();}
}
