红帽全球峰会2.2. 支持 JSON 格式的 JBoss Web 服务器日志
JBoss Web Server 6.1 引入了对以 JavaScript Object Notation (JSON)格式生成日志的支持。此功能使用 JSON 格式提供与单行日志格式相同的类型信息。
您可以通过两种方式在 JWS_HOME/tomcat/conf/logging.properties 文件中启用此功能：
如果您希望以 JSON 格式呈现控制台输出日志的
catalina.out文件，请将java.util.logging.ConsoleHandler.formatter属性设置为org.apache.juli.JsonFormatter。例如：
java.util.logging.ConsoleHandler.formatter = org.apache.juli.JsonFormatter
如果您希望以 JSON 格式呈现
catalina.log文件，请将1catalina.org.apache.juli.AsyncFileHandler.formatter属性设置为org.apache.juli.JsonFormatter。例如：
1catalina.org.apache.juli.AsyncFileHandler.formatter = org.apache.juli.JsonFormatter
有关 org.apache.juli.JsonFormatter 的更多信息，请参见 Apache Tomcat 文档。
