Question

感谢您对伐木的建议。如我所说，我尝试将自己的过滤器类包括在内 logging.properties文件：

这是我的appengine-.xml文件，指向 logging-properties文件：

<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
  <application>uthreee</application>
  <version>1</version>

  <!--
    Allows App Engine to send multiple requests to one instance in parallel:
  -->
  <threadsafe>true</threadsafe>

  <!-- Configure java.util.logging -->
  <system-properties>
    <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
  </system-properties>

  <sessions-enabled>true</sessions-enabled>

</appengine-web-app>

这是logging-properties文件

# A default java.util.logging configuration.
# (All App Engine logging is through java.util.logging by default).
#
# To use this configuration, copy it into your application's WEB-INF
# folder and add the following to your appengine-web.xml:
# 
# <system-properties>
#   <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
# </system-properties>
#
java.util.logging.FileHandler.filter=F

# Set the default logging level for all loggers to WARNING
.level = FINEST

而且，这是F.java

import java.util.logging.Filter;
import java.util.logging.LogRecord;

public class F implements Filter {
public boolean isLoggable(LogRecord lr) {
String Str = lr.getSourceClassName();
Str = Str.toUpperCase();
int pos1;
pos = Str.indexOf("STATUS");
pos1 =
System.out.println ("pos "+pos);
if (pos>=0) {
  return false;
}
else {
  return true;
}
}}

这是我想要抑制的日志信息：

Answer 1

LogManager类加载器can't see your custom filter class。 logging.properties实际上只适用于安装标准处理程序和在GAE中设置日志级别。如果要安装自定义过滤器，则必须使用ServletContextListener编写代码手动安装过滤器。
