Turn from: http://blog.csdn.net/tornadowp/article/details/8182496 1, log4j has become an essential part of large-scale systems, log4j can be very convenient to help us in any location of the program output to print information, easy for us to the system in the commissioning phase and the formal running phase of the problem analysis and positioning. Because of the different log level, the performance of the

Log4j is an excellent open source logging project, we can not only customize the format of the output log, but also define the destination of the log output, such as: screen, text file, database, even through the socket output. This section focuses on how to enter log information into a database (you can insert any database, which is explained in the example of MSSQL).Using log4j to write the log to the dat

Then there is a certain problem, the program continues to execute, and do not save the log in some way, for the information of the JVM output, it will continue to scroll down, and the length is not unlimited, then it is likely that you will lose the error message makes it difficult for you to solve the problem in the program, But with the log records that would be good to do, in the event of a problem you

Log4j is an open source project for Apache, by using log4j, we can control the destination of log information delivery is console, file, GUI component, even interface server, NT Event recorder, UNIX syslog daemon, etc. We can also control the output format of each log, and by defining the level of each log information, we can control the log generation process more carefully. Most interesting of all, these

Log4j is really familiar with almost all Java projects using it. But I didn't get it. Finally one day I can not stand, set heart to read a document, only two hours, I finally got it. Under normal circumstances log4j always with Apache commons-logging together, I will introduce it together. A lot of things are not more troublesome, but simpler. Log4j is really

I have been testing these days. The operating system is Solaris and JUnit is used, probably because my level is too low ). The first time I wrote a test case, many things were also vague. The function to be tested yesterday was to use log4j to output logs. As always, I wrote test cases, run JUnit, and input the name of the test case class, click the run button and the following error is found: Log4j: Er
