当实现Velocity时,我得到了这个错误(仅发布了"由"引起的"消息"):
java.lang.RuntimeException: Velocity could not be initialized!
Caused by: org.apache.velocity.exception.VelocityException: Error initializing log: Failed to initialize an instance of org.apache.velocity.runtime.log.Log4JLogChute with the current runtime configuration.
Caused by: org.apache.velocity.exception.VelocityException: Failed to initialize an instance of org.apache.velocity.runtime.log.Log4JLogChute with the current runtime configuration.
Caused by: java.lang.RuntimeException: Error configuring Log4JLogChute :
Caused by: java.io.FileNotFoundException: velocity.log (Permission denied)
这是我的代码片段:
VelocityEngine ve = new VelocityEngine();
ve.evaluate(context, writer, "org.apache.velocity.runtime.log.NullLogChute", this.templateString);
起初我的代码看起来像这样:
runtimeServices = RuntimeSingleton.getRuntimeServices();
node = runtimeServices.parse(reader, templateName);
在我的Windows机器上它工作正常,但在Linux系统(ubuntu 10.04)上它不起作用.这篇文章对我没什么帮助,因为我没有找到任何线索,我必须给出写权限.
我发现,以下代码也适用于Linux机器:
String logPath = request.getRealPath("/velocity.log"); …
