Add this code in your web.xml
在您的 web.xml 中添加此代码
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/loginDispacher-servlet.xml</param-value>
</init-param>
And this ligne code in your loginDispacher-servlet.
以及 loginDispacher-servlet 中的这个 ligne 代码。
<context:annotation-config />

Try to change your spring framework version in pom.xml to 4.1.5 Just add this before your dependencies
尝试将 pom.xml 中的 spring 框架版本更改为 4.1.5 只需在依赖项之前添加它
<properties>
<spring.version>4.1.5.RELEASE</spring.version>
</properties>

Both web.xml and applicationContext.xml xsd should be the same. Please change once.
web.xml 和 applicationContext.xml xsd 应该相同。请更改一次。
