java - 嵌套异常是 java.io.FileNotFoundException : Could not open ServletContext resource [/spring/servlet-context. xml]

Question

好的，感谢您帮助解决最后一个问题。这是我的新错误和随后的代码。错误中的粗体文本是我所关心的全部修复，因为这是唯一的错误。

[Thread-36] ContextLoader ERROR Context initialization failed org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from ServletContext resource [/spring/servlet-context.xml]; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/spring/servlet-context.xml] at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:341) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:302) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:143) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:178) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:149) at org.springframework.web.context.support.XmlWebApplicationContext.loadBeanDefinitions(XmlWebApplicationContext.java:124) at org.springframework.web.context.support.XmlWebApplicationContext.loadBeanDefinitions(XmlWebApplicationContext.java:93) at org.springframework.context.support.AbstractRefreshableApplicationContext.refreshBeanFactory(AbstractRefreshableApplicationContext.java:130) at org.springframework.context.support.AbstractApplicationContext.obtainFreshBeanFactory(AbstractApplicationContext.java:467) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:397) at org.springframework.web.context.ContextLoader.createWebApplicationContext(ContextLoader.java:276) at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:197) at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:47) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4701) at org.apache.catalina.core.StandardContext$1.call(StandardContext.java:5204) at org.apache.catalina.core.StandardContext$1.call(StandardContext.java:5199) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.io.FileNotFoundException: Could not open ServletContext resource [/spring/servlet-context.xml] at org.springframework.web.context.support.ServletContextResource.getInputStream(ServletContextResource.java:117) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:328) ... 19 more Oct 16, 2013 7:44:51 AM org.apache.catalina.core.StandardContext startInternal SEVERE: Error listenerStart Oct 16, 2013 7:44:51 AM org.apache.catalina.core.StandardContext startInternal SEVERE: Context [/mdimgmtsys-1.0-SNAPSHOT] startup failed due to previous errors

我所做的一切都无法在 Tomcat 中启动应用程序。

在 spring web 项目中，Application Context 和 Servlet Context 是有区别的。我们用来配置Application Context，用法和你的用法一样

<context-param>
    <param-name>contextAppConfigLocation</param-name>
    <param-value>classpath:app-context.xml</param-value>
</context-param>

对于 Servlet 上下文，默认 Web 容器将尝试在 WEB-INF 目录中查找#servlet-name#-servlet.xml，因此对于您的问题，您需要将您的移动到 WEB-INF 目录并更改其名称到相应的名称(contextServlet-servlet.xml，appServlet-servlet.xml)
