java - 使用 Tomcat 7、Apache Wink 和 Mongodb 在 WAR Deploy 上记录错误

标签 java mongodb ubuntu tomcat7 slf4j

我在将我的应用程序部署到我的 tomcat 服务器上时遇到问题。每次部署时我都会得到以下跟踪:

服务器上下文:

  • Ubuntu 12.04.3 LTS 32 位(我稍后会把它变成 64 位..)
  • Tomcat 7(唯一从标准安装修改的是为管理器 [-gui] 添加用户)

  • Java

    $ java -version
java version "1.6.0_27"
OpenJDK Runtime Environment (IcedTea6 1.12.6) (6b27-1.12.6-1ubuntu0.12.04.2)
OpenJDK Client VM (build 20.0-b12, mixed mode, sharing)

应用上下文:

我正在尝试转换概述的简单“书籍 REST 应用程序”here使用 Mongo 连接。我觉得 Mongo 部分在这里无关紧要。我还使用 Maven 和 Eclipse 来部署/构建项目。

我不想用代码污染帖子，所以如果您认为其他人有用，请告诉我。

感谢任何帮助。

最佳答案

java.io.IOException: Couldn't get lock for %h/java%u.log

看起来 Tomcat 没有写入日志文件的文件系统权限。 %h 变量是 user.home 系统属性的值，通常是运行 Tomcat 进程的系统用户的主目录。确保 Tomcat 对该目录具有写入权限。

该目录的位置可能会有所不同，但您可以通过编程方式找到它:

System.getProperty("user.home")

您还可以通过向 Tomcat 启动脚本提供参数 -Duser.home=/your/path 来修改默认值。
