log4j设置日志级别

前几天写了一个ifm_tt_sheet项目，从IFM向铁塔那边发送故障单，可是weblogic自带的jar包webservice中的某个包和我导入的jar包saaj.jar包路径内容完全一致，导致axis.jar一直抛空指针，查了这么多资料实在没有办法，找叶师傅帮忙，叶师傅说这个问题是axis抛的他写的这么多项目也是这样不用管。我想了想也实在没有招，大的环境变量不能动，配置weblogic.xml让提前加载导入的包又不行。就这样吧，虽然有点绝望，还是期望自己在看完一本webservice的书之后有所改变，因为空指针弄得log日志庞大，一分钟就达到4,5M的量，就想着把log的级别设置更高一极。

1、修改log4j.properties，其中若级别为info那么debug的异常将不在输出到日志上，只打印比info大的级别如（INFO 、 WARN 、 ERROR、 FATAL）

#DEBUG < INFO < WARN < ERROR < FATAL
log4j.rootLogger=INFO, A1, stdout
#log4j.rootLogger=DEBUG, A1, stdout 这是原先的配置

log4j.appender.A1=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A1.Encoding=UTF-8
log4j.appender.A1.File=e\:/log_tt_sheet/ifmttsheet.log
log4j.appender.A1.DatePattern=yyyy-MM-dd
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern= [%-5p][%d{HH:mm:ss.SSS}]:%x %l - %m%n

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern= [%-5p][%d{HH:mm:ss.SSS}]:%x %l - %m%n

这样一来，日志就简单多了，只打印发出去的xml和接收的xml。

关于webservice客户端报的空指针是：

差不多都是这样，头痛。把日志级别上升一个等级也只是掩耳盗铃罢了。不过这事叶师傅知道。
