Grails：Tomcat 中的 WAR 文件部署异常

Question

我有一个 Grails 应用程序正在尝试使用 WAR 文件部署在 Tomcat 服务器中。看起来很接近，但还有一个例外。

Grails版本是2.3.6，Tomcat版本是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，我会在控制台窗口中收到异常，并将其打印到 stacktrace.log 文件中。

请看下面的堆栈跟踪：

更新：

这个建议肯定有帮助。现在我能够克服那个异常，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。当我进入 Windows 任务管理器时，jave.exe 占用了几乎 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（控制器、服务、Quartz 作业等）的列表，并使用这些名称为 DefaultGrailsApplication 实例构建类数组.这是在DeploymentPackageJob 中调用静态初始化块（这就是<clinit> 的意思），这就是抛出NullPointerException。
