【问题描述】：

我的项目在通过 eclipse 和 tomcat 服务器 7 运行的本地机器上运行良好。我正在通过执行Maven install 生成 WAR 文件并将其部署到 tomcat 服务器中。部署后项目未运行并给出 404 Not Found。

在日志文件中我收到这样的错误：

有人可以帮我解决什么问题吗？我无法找出我做错的地方。我在pom.xml中设置了所有依赖项

【问题讨论】：

信息不足。发布更多日志
spring 无法实例化 PropertyUtil 。您可以发布异常原因吗？堆栈跟踪中的最后一个异常。来自错误日志：org.springframework.beans.factory.BeanCreationException：在 URL [jar:file:/Users/mindpro/Documents/apache-tomcat-7.0.59/webapps/crowdtxt/WEB 中定义名称为“propertyUtil”的 bean 创建错误-INF/lib/crowdtxt-persistence-0.0.1-SNAPSHOT.jar!/com/acinfotech/crowdtxt/jpa/util/PropertyUtil.class]：bean 的实例化失败；嵌套异常是 java.lang.ExceptionInInitializerError

标签： java spring tomcat war

【解决方案1】：

刚刚注意到这个项目在 Eclipse 中运行良好，但在独立服务器中运行良好。复制您在 eclipse tomcat 配置中设置的所有运行时属性并将其粘贴到独立的 tomcat catalaina 文件中。你可以找到 java opts 并添加它。

有一个空指针异常。

Caused by: java.lang.NullPointerException

at com.acinfotech.crowdtxt.jpa.util.PropertyUtil.<clinit>(PropertyUtil.java:23)

您可以在 PropertyUtil 类的第 86 行放置一个调试点。从方法名getPropertiesFromEnvironmentVariable看，估计是没有设置环境变量，或者取值有问题。

如果无法调试，则尝试使用 System.out.println 语句查看什么是 null。

希望你可以从这里调试。
