tomcat - Grails:Tomcat中的WAR文件部署异常

Question

我有一个 Grails 应用程序，它试图使用 WAR 文件在 Tomcat 服务器中部署。看起来很接近，但还有一个异常(exception)。

Grails版本为2.3.6，Tomcat版本为7.0.57

我已将 WAR 文件放在 Tomcat 的 webapps 文件夹中。

当我启动服务器时，我在控制台窗口中收到异常并将其打印在 stacktrace.log 文件中。

请看下面的堆栈跟踪:

更新:

这个建议绝对有帮助。现在我能够越过那个异常甚至部署 WAR。但是在部署 WAR 之后，这次我遇到了一些内存异常。

请查看控制台窗口的输出。当我转到 Windows 任务管理器时，jave.exe 占用了将近 70 - 80% 的 CPU。

Answer 1

我会说这将是寻找的地方:

at com.hidglobal.rpsproxy.DeploymentPackageJob.<clinit>(DeploymentPackageJob.groovy)
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:274)
at org.codehaus.groovy.grails.commons.GrailsApplicationFactoryBean.afterPropertiesSet(GrailsApplicationFactoryBean.java:79)

在启动时，Grails 解析 /WEB-INF/grails.xml其中包含所有工件类名称( Controller 、服务、Quartz 作业等)的列表，并使用这些名称为 DefaultGrailsApplication 构建类数组。实例。这是在 DeploymentPackageJob 中调用静态初始化程序 block (这就是 <clinit> 的意思)这就是抛出一个 NullPointerException .
