更改OWasp CSRFGuard的日志记录级别

Question

我已经成功地在我的Java应用程序中安装了OWasp CSRFGuard。

我的CSRFGuard.Properties文件包含以下内容：

# Logger
#
# The logger property (org.owasp.csrfguard.Logger) defines the qualified class name of 
# the object responsible for processing all log messages produced by CSRFGuard. The default
# CSRFGuard logger is org.owasp.csrfguard.log.ConsoleLogger. This class logs all messages
# to System.out which JavaEE application servers redirect to a vendor specific log file.
# Developers can customize the logging behavior of CSRFGuard by implementing the
# org.owasp.csrfguard.log.ILogger interface and setting the logger property to the new
# logger's qualified class name. The following configuration snippet instructs OWASP CSRFGuard
# to capture all log messages to the console:
#
# org.owasp.csrfguard.Logger=org.owasp.csrfguard.log.ConsoleLogger
 org.owasp.csrfguard.Logger=org.owasp.csrfguard.log.JavaLogger

我可以从https://www.javatips.net/api/OWASP-CSRFGuard-master/csrfguard/src/main/java/org/owasp/csrfguard/log/JavaLogger.java看到不同的日志记录级别

   LOGGER.log(Level.FINEST, exception.getLocalizedMessage(), exception);
        break;
    case Debug:
        LOGGER.log(Level.FINE, exception.getLocalizedMessage(), exception);
        break;
    case Info:
        LOGGER.log(Level.INFO, exception.getLocalizedMessage(), exception);
        break;
    case Warning:
        LOGGER.log(Level.WARNING, exception.getLocalizedMessage(), exception);
        break;
    case Error:
        LOGGER.log(Level.WARNING, exception.getLocalizedMessage(), exception);
        break;
    case Fatal:
        LOGGER.log(Level.SEVERE

如何将CSRFGuard.Properties中的日志记录级别更改为目前仅显示Level.WARNING，每个请求都会被分析和记录。

替换CSRFGuard.Properties中的以下行

 org.owasp.csrfguard.Logger=org.owasp.csrfguard.log.JavaLogger

使用

org.owasp.csrfguard.Logger=com.myPackage.MyLogger

并添加一个新类，如下所示(基于this code)，在MyLogger()构造函数中设置所需的日志级别(在下面的示例中，我将最低日志级别设置为Level.WARNING)

package com.myPackage

import java.util.logging.Level;
import java.util.logging.Logger;

import org.owasp.csrfguard.log.LogLevel;

public class MyLogger implements org.owasp.csrfguard.log.ILogger {

    private static final long serialVersionUID = 1L;

    private final static Logger LOGGER = Logger.getLogger("Owasp.CsrfGuard");
    
    public MyLogger() {
        LOGGER.setLevel(Level.WARNING);
    }
    
    @Override
    public void log(String msg) {
        LOGGER.info(msg.replaceAll("(\\r|\\n)", ""));
    }

    @Override
    public void log(LogLevel level, String msg) {
        // Remove CR and LF characters to prevent CRLF injection
        String sanitizedMsg = msg.replaceAll("(\\r|\\n)", "");
        
        switch(level) {
            case Trace:
                LOGGER.finest(sanitizedMsg);
                break;
            case Debug:
                LOGGER.fine(sanitizedMsg);
                break;
            case Info:
                LOGGER.info(sanitizedMsg);
                break;
            case Warning:
                LOGGER.warning(sanitizedMsg);
                break;
            case Error:
                LOGGER.warning(sanitizedMsg);
                break;
            case Fatal:
                LOGGER.severe(sanitizedMsg);
                break;
            default:
                throw new RuntimeException("unsupported log level " + level);
        }
    }

    @Override
    public void log(Exception exception) {
        LOGGER.log(Level.WARNING, exception.getLocalizedMessage(), exception);
    }

    @Override
    public void log(LogLevel level, Exception exception) {
            switch(level) {
            case Trace:
                LOGGER.log(Level.FINEST, exception.getLocalizedMessage(), exception);
                break;
            case Debug:
                LOGGER.log(Level.FINE, exception.getLocalizedMessage(), exception);
                break;
            case Info:
                LOGGER.log(Level.INFO, exception.getLocalizedMessage(), exception);
                break;
            case Warning:
                LOGGER.log(Level.WARNING, exception.getLocalizedMessage(), exception);
                break;
            case Error:
                LOGGER.log(Level.WARNING, exception.getLocalizedMessage(), exception);
                break;
            case Fatal:
                LOGGER.log(Level.SEVERE, exception.getLocalizedMessage(), exception);
                break;
            default:
                throw new RuntimeException("unsupported log level " + level);
        }
    }
