第二步
commons-logging.properties 里增加
org.apache.commons.logging.Log = org.apache.commons.logging.impl.Log4JLogger
org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.LogFactoryImpl
第三步
log4j.properties
增加
log4j.rootLogger=ERROR, stdout
#log4j.rootCategory=ERROR, stdout , R
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %t %c{2}:%L - %m%n
再说点======================================
查看使用的LOG方法
public class Test {private static final Log LOG = LogFactory.getLog(Test.class); ???public static void main(String[] args) { ???????System.out.println("log:" + LOG); ???????LOG.trace("我是trace信息"); ???????LOG.debug("我是debug信息"); ???????LOG.info("我是info信息"); ???????LOG.warn("我是warn信息"); ???????LOG.error("我是error信息"); ???????LOG.fatal("我是fatal信息"); ???????????} ???}httpclient log 输出太多隐藏
