我遇到此异常：
[[ERROR] SRVE0777E：应用程序类引发异常'javax.el.BeanELResolver $ BeanProperties.get：245'javax.el.PropertyNotFoundException：在类型上找不到属性“索引”java.lang.String
我见过很多解决方案，但都具有相同的异常，但是在异常在类型java.lang.String上找不到属性'index'的情况下，我找不到这个特定的（'index'），但是我知道这也是String和其他字符串一样，但是找不到解决方案。
我已经删除了所有样板代码，只是为了检查Controller是否渲染了jsp页面，但是以某种方式甚至删除了它仍然给出所提到的异常的所有代码。
我在网上很少找到答案，其中字符串是POJO的一部分，而问题与POJO有关，但在我的情况下，POJO中没有定义变量'index'。
任何人都可以让我知道我做错了什么。

我得到此异常：[错误] SRVE0777E：应用程序类'javax.el.BeanELResolver $ BeanProperties.get：245'javax.el.PropertyNotFoundException：属性'index'引发的异常：]'
