JFinal 存入数据库数据出错 400 请求报错 

@JFinal 你好，想跟你请教个问题：

T_section section=new T_section(); String sectionId = ele.elementText("SectionId"); String sectionName = ele.elementText("SectionName"); section.set("sectionId", sectionId); section.set("sname", sectionName); section.set("hid", hid); section.save(); System.out.println("更新成功"); 错误信息是：
