Example of how MyBatis3 outputs SQL using log4j on the console, mybatis3log4j Why do I need to output SQL statements on the console? Of course, it is convenient for development and debugging. If a database-related operation encounters a problem, we can quickly troubleshoot the problem based on the output SQL statement. Output Information: [Org. mybatis. spring.

One: log4j Introduction to Learning 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

I have been using logs encapsulated by others for some time. I feel very curious when I have configured logs. Next we will record the common usage of using log4j to process logs. As for what log4j is, I don't know what it is, and I don't think it is necessary to go too deep for the moment. I only know that it is a good choice to process logs.Game starts References 1) official PDF document 2) Configure

During application development, logs can be used to debug programs and track program running tracks. During the program running process, you can record the running status of the program and use it for auditing. Log4j is a popular implementation that supports multiple log implementations. This section describes how to use log4j logs. The use of log4j logs includes

With the rapid development of technology, day after day passed, the old server finally to the retirement of the day This means migrating old server data to a new server, where one of the key projects migrates the host role The new server needs to be promoted to an additional domain controller prior to migration http://wenxiong.blog.51cto.com/405708/1120831 After the upgrade, the host role will be migrated!

Mr Yan Xin, Senior Development Manager of Microsoft, finished reading the famous "migration path". Before reading it, he thought that if he only looked at the directory, what kind of questions do I have or what do I want to know most? Today, after reading a book, you can select a few topics you are interested in and share them with you in Q . 1. Q: What do you think?CodeReview and pairing programming? A:Code Review: checks whether the code solves

porting libraries requires considerations (how the files generated by the migration Library are used) General induction of the migration of simple libraries 1. File location After migration general Select a new folder under the opt/directory, such as Opt/lib-codec 2. Configuration options typically require the identification of compilation tools and link Tools ,

Through the previous introduction we know that the main line link is due to the db_block_size of the database is not large enough for some large fields can not be stored in a block, resulting in a row link. For row links We have nothing to avoid except to increase db_block_size, but since the database was built Db_block_size is immutable (before 9i), we can specify different table spaces for the oracle9i database db_ Block_size, therefore, the production of line links is almost inevitable, there

What is log4j? Log4j is a tool that helps programmers output log statements to a variety of output targets. The LOG4J package is designed so that log statements can remain in the published code without producing high-performance costs. LOG4J uses 分层记录器 the ability to selectively control which log state
