Java Jar未加载。无法启动组件[StandardEngine[Catalina]。StandardHost[localhost]

我遇到了以下错误，我尝试将jdk版本更改为1.7，并将JRE更改为7版，但不起作用。我还尝试在Java构建路径中添加jar文件，但仍然不起作用

这一行指出了主要问题：

Caused by: java.lang.NoClassDefFoundError: 
    org/springframework/web/context/request/async/CallableProcessingInterceptor

看起来您缺少一个Spring JAR文件，或者您的版本错误。根据javadocs，Spring 3.2中添加了

CallableProcessingInterceptor

第二个（较小）问题如下所示：

      .metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\

您似乎已经将

jsp api

和

servlet api

jar放入了webapp的lib目录中。您不应该这样做。jsp和servlet实现已经在webapp的类路径上……由Tomcat自己提供。

您需要将以下jar文件添加到您的web inf/lib文件夹中，还需要配置我查看构建路径——右键单击您的项目——构建路径——配置构建路径——库——添加外部jar（添加以下所有jar文件）。然后重新启动服务器

除了删除一个巨大的stacktrace，您还可以添加一些关于问题的上下文以及您试图解决它的内容。谢谢您，我添加了spring jar，现在它显示了不同的错误[org.springframework.web.context.ContextLoader]-上下文初始化失败org.springframework.beans.factory.BeanCreationException:创建名为“org.springframework.Context.support.propertySourcesplaceConfigurer#0”的bean时出错：初始化bean失败；嵌套异常为java.lang.NoClassDefFoundError:org/springframework/core/SpringPropertiesCaused by:java.lang.NoClassDefFoundError:org/springframework/core/SpringProperties由以下原因引起：java.lang.ClassNotFoundException:org.springframework.core.SpringProperties我已经在pom.xml org.springframework spring context 3.2.1.RELEASE org.sprin中包含以下jargframeworkspringweb3.2.1.RELEASE我建议您查看webapp中实际部署的JAR文件。如有必要，使用

JAR

和

javap

命令查看JAR文件中的实际内容。
