我已经更新了tomcat的logging.properties文件以以json格式打印日志。但是，问题是“message”的值有一些转义字符，这使得我的日志无效 json。请让我知道如何使用默认的 tomcat-juli.jar 转义 json 中的这些字符（:,[,],/）并用作字符串。
以下是我更新的logging.properties文件：
handlers = 1catalina.org.apache.juli.AsyncFileHandler, 2localhost.org.apache.juli.AsyncFileHandler, 3manager.org.apache.juli.AsyncFileHandler, 4host-manager.org.apache.juli.AsyncFileHandler, java.util.logging.ConsoleHandler
.handlers = 1catalina.org.apache.juli.AsyncFileHandler, java.util.logging.ConsoleHandler
