How can we separate the required content from the original log, what about creating a separate log file? In fact, you can easily implement this function with a slight

Log4j introduction: Log4j is a powerful logging tool that records operation information in the system and helps administrators analyze and manage related data in the background. You can record the data console, files, interface servers, and GUI components. You can configure or flexibly record the log format through your own configuration to achieve data analysis

The WebService written in Java is used to establish a database connection because the WebService interface is intended for many users. In this case, if you write the database connection statement in our method called by the user, you can use the method before closing it. However, with the Tomcat connection pool, 25 connections can be applied for at most 50 (both 25 and 50 can be configured) at the beginning, saving a lot of time for creating and disabling connections, better compression capabili

The log4j. properties configuration file is described as follows: # Set root logger level to debug and its only appender to A1 # Log4j has five levels of logger # Fatal 0 # Error 3 # Warn 4 # INFO 6 # Debug 7 Configure the root logger with the Syntax: # Log4j. rootlogger = [level], appendername, appendername ,...

The configuration fails according to many configuration steps on the Internet. Now let's look back at the inconsistency of most versions. In addition, log4j is flexible in addition to managing logs for the entire container, it can also manage logs for a project. If there are only logs in the container, what should we do with the logs in JUnit? Therefore, project

In general, some important logs in our project want to be output to the specified file separately, instead of the total output to the System Log File. Therefore, log4j provides us with this function, next, let's take a step-by-step look at how it works. This is written in the property configuration mode. The XML method is similar.
