mybatis怎么配置log4j打印出sql语句

Answer 1

mybaits提供两种日志打印的机制，一个是common；一个是slf4j

Java代码
@Test
public void shouldUseCommonsLogging() {
LogFactory.useCommonsLogging();
Log log = LogFactory.getLog(Object.class);
logSomething(log);
assertEquals(log.getClass().getName(), JakartaCommonsLoggingImpl.class.getName());
}

@Test
public void shouldUseLog4J() {
LogFactory.useLog4JLogging();
Log log = LogFactory.getLog(Object.class);
logSomething(log);
assertEquals(log.getClass().getName(), Log4jImpl.class.getName());
}
