Question

我使用了速度-1.6.2.jar

我在服务器上创建 velocity.log 的问题是从 jboss / bin

开始的

jboss / bin 拥有只读权限。

并在我的appilcation中调用velocity-1.6.2.jar时出现此错误：

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

我想更改Velocity.Log文件的位置

这是我的速度属性中的位置线：

# ----------------------------------------------------------------------------
#  default LogChute to use: default: AvalonLogChute, Log4JLogChute, CommonsLogLogChute, ServletLogChute, JdkLogChute
# ----------------------------------------------------------------------------

runtime.log.logsystem.class = org.apache.velocity.runtime.log.AvalonLogChute,org.apache.velocity.runtime.log.Log4JLogChute,org.apache.velocity.runtime.log.CommonsLogLogChute,org.apache.velocity.runtime.log.ServletLogChute,org.apache.velocity.runtime.log.JdkLogChute

# ---------------------------------------------------------------------------
# This is the location of the Velocity Runtime log.
# ----------------------------------------------------------------------------

runtime.log = velocity.log

Answer 1

Runtime log可以获得完整路径，只需直接登录到您的可摘文件夹/home/velocity.log

 runtime.log = /home/velocity.log

错误，警告和信息性消息的日志文件的完整路径和名称。如果不是绝对的，该位置相对于当前目录＆＃39;。

日志路径也可以通过编程方式设置如下：

import org.apache.velocity.app.VelocityEngine;
public class VelocityCustomEngine extends TemplateEngine {

    private final VelocityEngine velocityEngine;

    public VelocityCustomEngine() {
        Properties properties = new Properties();
        properties.setProperty("runtime.log", "/home/velocity.log");

        this.velocityEngine = new VelocityEngine(properties);
    }
}

Answer 2

我知道有答案。如果您不想扩展原始的VelocityEngine。您还可以新建一个VelocityEngine实例，仅在init（）方法之前更改“ runtime.log”属性，而无需任何新类。

        VelocityEngine velocityEngine = new VelocityEngine();
        velocityEngine.setProperty("runtime.log", "/home/velocity.log");
        velocityEngine.setProperty(RuntimeConstants.ENCODING_DEFAULT, "UTF-8");
        velocityEngine.setProperty(RuntimeConstants.RESOURCE_LOADER, "classpath");
        velocityEngine.setProperty("classpath.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
        velocityEngine.init();//init method will use the properties(include the log file location) actually.
        return velocityEngine;

更改Velocity.Log文件的位置
