java.lang.NullPointerException] with root cause
报错大体内容
java.lang.NullPointerException] with root cause
写在前面
说明：这只是我发现的其中一个缘由，可能你的和我有所不一样。若是没有解决问题，轻喷。。java
项目简介
SSM项目，用eclipse开发。segmentfault
背景说明
商城后台添加商品。填写完商品的相关信息后，提交表单，报错。eclipse
缘由
填写的时候，所输入的值要和POJO实体类的属性的类型一致，不然就报错测试
例子
前台页面及部分代码
后台POJO类
因为POJO类中price的类型是Double，那商品价格一栏就不要输入字符串（本身最开始测试时随便输入了一些字母，报错了，改输为数字便可。）url
