FileNotFoundException: 类路径资源 [WEB-INF/dispatcher-servlet.xml] 无法打开，因为它不存在时它确实存在

Question

我已将 dispatcher-servlet.xml 放在 WEB-INF 文件夹中，该文件夹位于 webapp 文件夹中。仍然抛出错误：类路径资源 [WEB-INF/dispatcher-servlet.xml] 无法打开，因为它不存在。

异常：从类路径资源 [WEB-INF/dispatcher-servlet.xml] 解析 XML 文档时出现意外异常；嵌套异常是 java.lang.NoSuchMethodError: org.springframework.beans.MutablePropertyValues.add(Ljava/lang/String;Ljava/lang/Object;)Lorg/springframework/beans/MutablePropertyValues;

无法跟踪错误，哪里出错了？

下面是我的 dispatcher-servlet.xml

有什么错误的建议吗？

Answer 1

更新

您的项目使用了太旧的依赖项

像这样更改以在 pom.xm 中使用 Java 8

<build>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.5.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>

并将这个 version 的 spring 用于您的遗留项目

<spring.version>3.0.5.RELEASE</spring.version>

---

请确保您的 web.xml 中有这种配置

  <servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfiguration</param-name>
      <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
