My all XML configuration files of SpringMVC project show some error that they can't recognize the symbol in the files

Question

I don't know how those error occured,the project goes no any problem just now.

I remember I renamed the index.jsp and create a new RestController.

The error say "Element param-serviceName is not allowed here".

Here are some images show the errors

web.xml:

web.xml

applicationContext.xml:

applicationContext.xml

and the code of the web.xml as follows,others xml files like the web.xml

web.xml

most probably file encoding may have changed. which IDE you are using. — Acewin, Aug 22 '17 at 16:13
I tried many method,but all useless.Now I intend to create a new project, the source files are copied into it — widiot, Aug 22 '17 at 16:25
happened to me as well a few times. Mostly due to file sync errors. closing and opening IDE multiple times or recreating file helped. — Acewin, Aug 22 '17 at 16:26
Thank you very much.I tried restart the IDE and recreate the web.xml,but all are useless.The last way is to create a new project,I can only do that now. — widiot, Aug 22 '17 at 16:52

Consider this my mistake to not be able to help OP properly

The issue in your web.xml is, it is using wrong tags.

update your web.xml to this and then try.

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
     http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">

    <!--配置Spring核心监听器-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--指定Spring的配置文件-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>

    <!--Spring MVC的前端控制器-->

I finally know what happened, because I used the IDEA's rename to rename a property named "name" to "serviceName",the IDEA actually rename all the "name",including the XML.I want to curse. — widiot, Aug 23 '17 at 03:55
