初学spring
/WEB-INF/pages/admin/addUser.jsp (行.: [34], 列: [4]) 不能为属性:[commandName]找到setter 方法. 在addUser,jsp页面里面的commandName属性值name被提示can't resolve symbol user。 百度了一圈也没找到自己想要的内容。 有看到这个兴许简单的问题的大神回答一下感激不尽。
一开始我并没有注意这个问题，没有修改直接运行项目是正确的，但是我想起来前面好像有把这个格式修改。试了很多次最后确定就是这个错误导致的。修改过后无论是post或者是get请求都是正常的。 报错截图如下  奇怪的是console并没有任何提示，只有页面报这个错。
