无法打开类路径资源[java/lang/Object.class]，因为它不存在

我对SpringWeb应用程序有一个奇怪的问题。这来自Tomcat日志：

INFO: Closing Spring root WebApplicationContext

这是我的

WebConfig

课程：

@EnableWebMvc
@Configuration
@ComponentScan(basePackages = {"com.jverstry", "org.krams"})
@ImportResource("WEB-INF/spring-security.xml")
public class WebConfig extends WebMvcConfigurerAdapter {

    @Bean
    public ViewResolver getViewResolver() {

        InternalResourceViewResolver resolver
            = new InternalResourceViewResolver();
        resolver.setPrefix("WEB-INF/pages/");
        resolver.setSuffix(".jsp");

        return resolver;

    }

}

这是最奇怪的

让我们从我们所知道的开始。类

java.lang.Object

和相应的

java/lang/Object.class

文件肯定存在。如果他们没有这样做，那么JVM从一开始就不太可能启动

那你怎么会有例外呢

我的理论是，在您的代码库（或您正在使用的库）的某个地方，有一个违反规则的类加载器。当要求加载资源时，行为良好的类加载器将首先向上委托类加载器链，以查看其父类加载器是否可以加载资源。我怀疑发生的情况是，坏掉的类加载器跳过了委托步骤，只是试图加载资源本身。如果“rt.jar”不在其jar等列表中（通常不会），那么类装入器将找不到Object.class文件。。。您将得到一个

FileNotFoundException

---

更新

我想我明白了。如果Java安装已损坏到无法加载

Java.lang.Object

，则JVM将无法启动。如果它在崩溃之前已经启动了，那么它就不会试图加载

对象

类

但它并没有试图这样做。它实际上是在试图读取

Object.class

文件。stacktrace似乎在说这发生在Spring的注释处理代码中

因此，我认为在Java安装被破坏后，有什么东西触发了servlet重启。重新启动导致spring配置再次完成。当你重新启动时，它为什么起作用是个谜。。。除非问题是由于硬件错误或设备驱动程序被重新启动清除而导致的

---

（你找到的帖子描述了一个不同的场景……JVM在引导过程中失败。你的场景更复杂。）

结果是我的JRE6安装不知怎么被破坏了。我手动重新安装了它，现在我没有问题了。我还发现了另一个可能解释重新启动后问题消失的原因

重新启动后，问题消失了。我注意到一些操作应用程序不起作用。我想我的本地tomcat安装变得不稳定了。

@EnableWebMvc
@Configuration
@ComponentScan(basePackages = {"com.jverstry", "org.krams"})
@ImportResource("WEB-INF/spring-security.xml")
public class WebConfig extends WebMvcConfigurerAdapter {

    @Bean
    public ViewResolver getViewResolver() {

        InternalResourceViewResolver resolver
            = new InternalResourceViewResolver();
        resolver.setPrefix("WEB-INF/pages/");
        resolver.setSuffix(".jsp");

        return resolver;

    }

}
