速度和log4J出错

标签： java servlets log4j stack-trace velocity

我构建了一个在我的localhost（tomcat）中完美运行的webapp。但是当我尝试部署时，在init（）中速度崩溃，让我在这里留下这个奇怪的堆栈跟踪（抱歉大小）：

有谁知道解决方法？或者至少了解错误？我做了一些谷歌搜索，但没有线索..只有这个page面临同样的问题，但没有解决方案..

6 个答案:

答案 0 :(得分：35)

Velocity试图将日志文件放在Tomcat启动的目录中，我相信这实际上是/.

您可以通过将这些行添加到velocity.properties来强制Velocity登录到Tomcat的标准日志：

runtime.log.logsystem.class=org.apache.velocity.runtime.log.SimpleLog4JLogSystem
runtime.log.logsystem.log4j.category=velocity
runtime.log.logsystem.log4j.logger=velocity

velocity.properties应该进入/WEB-INF/velocity.properties，但你可以在web.xml中的servlet定义中覆盖它。

如果您是按属性初始化Velocity而不是velocity.properties：

VelocityEngine engine = new VelocityEngine();

Properties props = new Properties();
props.put("runtime.log.logsystem.class", "org.apache.velocity.runtime.log.SimpleLog4JLogSystem");
props.put("runtime.log.logsystem.log4j.category", "velocity");
props.put("runtime.log.logsystem.log4j.logger", "velocity");

engine.init(props);

答案 1 :(得分：9)

我认为这一行有答案。看起来创建velocity.log文件时出现问题。您的配置文件是什么样的？

Caused by: java.io.FileNotFoundException: velocity.log (Permission denied)

答案 2 :(得分：4)

尝试打开日志文件的过程似乎无权执行此操作：

Caused by: java.io.FileNotFoundException: velocity.log (Permission denied)

答案 3 :(得分：1)

我也有相同的问题，但我能够解决此问题，将默认日志文件覆盖到自定义日志文件。只需在您调用evaluate Function的方法中添加这3行代码。

Velocity.setProperty(RuntimeConstants.RUNTIME_LOG_LOGSYSTEM_CLASS,"org.apache.velocity.runtime.log.Log4JLogChute");

Velocity.setProperty("runtime.log.logsystem.log4j.logger","com.mindtree.igg.website.email.TemplateMergeUtilVelocityImpl");

VelocityContext velocityContext = new VelocityContext(parameters);

这是解决问题的一种方法，即不使用属性文件。

答案 4 :(得分：0)

我遇到了同样的问题，并编写了一个描述性博客，其中包含可能的原因和解决方案。这是link

答案 5 :(得分：0)

我的代码遇到了完全相同的问题，经过数小时的谷歌搜索后，我决定在我的项目中添加一些其他Velocity库。 我的项目只有apache-velocity jar文件，然后从here，我还将Velocity-Dep添加到我的Maven项目和Yesssssssssss！ VICTORY！
