java.lang.NullPointerException] with root cause
報錯大體內容
java.lang.NullPointerException] with root cause
寫在前面
說明：這只是我發現的其中一個緣由，可能你的和我有所不一樣。若是沒有解決問題，輕噴。。java
項目簡介
SSM項目，用eclipse開發。segmentfault
背景說明
商城後臺添加商品。填寫完商品的相關信息後，提交表單，報錯。eclipse
緣由
填寫的時候，所輸入的值要和POJO實體類的屬性的類型一致，不然就報錯測試
例子
前臺頁面及部分代碼
後臺POJO類
因爲POJO類中price的類型是Double，那商品價格一欄就不要輸入字符串（本身最開始測試時隨便輸入了一些字母，報錯了，改輸爲數字便可。）url
