Today, I was very busy. I wanted to write more content. There is no way to do it now. I have to pick up a simple component and write it down. I will introduce the components in the following chapters.
The use of LtLogger is relatively simple. The
1Under SRC, create a new file named Log4j.properties content as follows: for file Log4j.rootlogger=WARN, stdout# log4j.rootlogger=WARN, stdout, logfilelog4j.appender.stdout =Org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.layout=
The stack call log that causes the program to crash writes to the file for easy collection of bugs. In Debugging the Android program, for some reason the phone can not connect to the PC side, the IDE can not see the program crashed log, I hope log
Today more busy, originally wanted to write more content, temporarily no way, pick a relatively simple components to write down, the next few chapters are introduced components.

The Out,error in system are final type and cannot be changed. However, the new output stream can be set through SetOut (), thus enabling the ability to write logs.

JDK built-in log system and jdk built-in log
1. Log functions in Java applications
========================
Generally, Java applications require logging. Currently, the mainstream log recording method is to introduce log4j in the application and use log4j to generate logs. In fact, JDK has its own log system, which is easy to use.
2. Use of Java built-in logs
========================
Classes related to the jdk built-in log system are included in the java. util. logging package. The following ex
Log4cplus is excellent in many aspects, but it is uncomfortable to use it in some places. I'm not happy with it until I continue to talk about it.I will mention it a little and continue to introduce the knowledge about threads and sockets.
### Some improvements ###
1. The implementation mechanism of user-defined loglevel is not open enough
In article 5, I have introduced how to implement custom loglevel. To achieve better results, I even need to change log4cplus.Source code. :(
2. The mechanism
, appenders, and layouts ). These three types of components work together so that developers can record them based on the type and level of information and control the output format and location of the information at runtime.
3.1 log category hierarchy (loggers)
The primary advantage of log4j over the simple use of the system. Out. println () method is its ability to disable some specific information output without compromising the output of other information. This capability is derived from the
Log output is a prerequisite for all systems, and many developers may not be able to relate to the JDK logging modules because they often use log4j. What is the connection. How the JDK logging handles the details. This week, first analyze the JDK logging mechanism. * * Starting from the example
The use of JDK logging is simple, as shown in the following code, where you can get a logger by using the static method of the
