我的SpringMVC项目的所有XML配置文件都显示了一些错误，他们无法识别文件中的符号

Question

我不知道这些错误是怎么发生的，项目现在没有任何问题。

我记得我重命名了index.jsp并创建了一个新的RestController。

错误说＆＃34;这里不允许使用Element param-serviceName＆＃34;。

以下是一些显示错误的图片

的web.xml：

的applicationContext.xml：

和web.xml的代码如下，其他xml文件如web.xml

的web.xml

<?xml version="1.0" encoding="UTF-8"?>

考虑到我的错误是无法正确帮助OP

你的web.xml中的问题是，它使用了错误的标签。

将您的web.xml更新为此，然后尝试。

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
