java.util.logging

问题 I set logging level to CONFIG, but don't see messages written on CONFIG level. What I am missing? Configuration: Logger logger = java.util.logging.Logger.getLogger("xxx"); logger.setLevel(java.util.logging.Level.CONFIG); Tests: logger.log(java.util.logging.Level.SEVERE, "severe"); logger.log(java.util.logging.Level.WARNING, "warning"); logger.log(java.util.logging.Level.INFO, "info"); logger.log(java.util.logging.Level.CONFIG, "config"); logger.log(java.util.logging.Level.FINE, "fine");

问题 I'd like to have 2 webapp under a tomcat, the 2 project should have their own logging.properties. I know this is possible, if you put logging.properties in the war file, but I'd like to specify a custom loggin.properties file (out of my deployed war). Is that possible? 回答1: You can specify what file will be used. The ${catalina.base}/conf/logging.properties file is referenced by Tomcat startup scripts, catalina.sh : LOGGING_CONFIG (Optional) Override Tomcat's logging config file LOGGING

问题 I used the below code to configure my logging. public Boolean configureLogPath(String logPath, String level, String logComponents, int logFileSize, int logFileCount) { int logFileSizeInKbs = logFileSize * 1000; Boolean result = false; String[] splitComponents = logComponents.split(","); for (String component : splitComponents) { loggableComponents.add(component); } switch (level) { case "info": LOGGER.setLevel(Level.INFO); break; case "severe": LOGGER.setLevel(Level.SEVERE); break; case

问题 I have a persistent event-driven HTTP upload program (hot folder) that writes to a log on every action. It runs indefinitely until the user decides to close it. To ensure the log is closed when the application is closed, I have written the program so on every write to log, it opens the log file, writes to it, and then closes the log. Like so: fh = new FileHandler(logName, true); fh.setFormatter(new MyCustomFormatter()); logger.addHandler(fh); logger.info(message); logger.removeHandler(fh); fh

问题 i wrote a log server that eats the stuff coming from a bunch of sockethandlers on other devices and writes it to a log file which looks like: <?xml version="1.0" encoding="UTF-8" standalone="no"?> <!DOCTYPE log SYSTEM "logger.dtd"> <log> <record> <date>2016-05-15T06:40:03</date> ... </record> ... i am new to chainsaw. chainsaw can open these files using: load java util file. if i add a simple receiver for port 4445, i get a bind exception. if i add a simple receiver for port 4560, i get the

问题 I have to use a custom logger for Tomcat. Extending java.util.logging.Handler I implemented a bridge to the custom logger. It gets instanciated via WEB-INF/classes/logging.properties . But it needs to beconfigured by a property file from the war. So I need the ServletContext to do servletContext.getResourceAsStream(iniFileName) . Since the custom Logger is created by the java logging mechanism, I am not able to get the ServletContext from a Servlet constructor or via dependency injection. How

问题 I want the Java ConsoleHandler to use System.out instead of err , so I implemented my own handler that calls the protected void setOutputStream(OutputStream) of the parent StreamHandler class: public class ConsoleHandler extends java.util.logging.ConsoleHandler { public ConsoleHandler() { setOutputStream(System.out); // or System.err setLevel(Level.ALL); } } I remove the default console logger from and add my own to the root logger: Logger l = Logger.getLogger(""); for (Handler h : l

问题 My aim is to use the java.util.logging Level class and change the Level strings like 'FINE' to 'VERBOSE'. public static final Level FINE = new Level("FINE", 500); I know we can do this by extending the Level as follows: public class MyLogLevel extends Level { private static final long serialVersionUID = -8176160795706313070L; private static final Level FINE = new MyLogLevel("VERBOSE", 500); protected MyLogLevel(String name, int level) { super(name, level); } } I would like to know, is this

问题 i have a java application. I export my project as a .war file, build a docker container and run it. In my application i define my variable: private static final Logger logger = Logger.getLogger(BusController.class.getName()); And for the output i use for example: logger.warning("User "+XYZ+" not found!"); Then i have created a logback.xml, that the logs will be saved at my HDD with a timestemp. I found the solution for this also here. <?xml version="1.0" encoding="UTF-8"?> <configuration>

问题 this problem makes me crazy. I'm using glassfish V2.1 and JDK 1.6.0_27 on Kubuntu 12.04. If i start the server i got this exception Starting Domain domain1, please wait. Default Log location is /usr/share/glassfish-v2.1-b60e/domains/domain1/logs/server.log. Redirecting output to /usr/share/glassfish-v2.1-b60e/domains/domain1/logs/server.log recursive call into SystemOutandErrhandler java.lang.RuntimeException: recursivecall at com.sun.enterprise.server.logging.SystemOutandErrHandler
