[b]问题补充：[/b]
能说具体点吗？
在线 等
我没有说清楚
[b]SLF4J versions 1.4.0 and later requires log4j 1.2.12 or later[/b]
The trace level was added to log4j in version 1.2.12 released on August 29, 2005. The trace level was added to the SLF4J API in version 1.4.0 on May 16th, 2007. Thus, starting with SLF4J 1.4.0, the log4j binding for SLF4J requires log4j version 1.2.12 or above.
However, as reported in bug 68, in some environments it may be difficult to upgrade the log4j version. To accomodate such circumstances, SLF4J's Log4jLoggerAdapter will map the TRACE level as DEBUG.
你可是访问这个网址看一下你的出错原因:
[url]http://www.slf4j.org/codes.html#log4j_version[/url]
在网页的最下面.
Log4j的1.2.9下载地址:
[url]http://archive.apache.org/dist/logging/log4j/1.2.9/logging-log4j-1.2.9.zip[/url]
你解压后,将dist\lib下的log4j-1.2.9.jar考到你的项目lib中,应该就可以了.
This version of SLF4J requires log4j version 1.2.12 or later. See also http://www.slf4j.org
你的log4j版本低了，你去换一个1.2.12后的版本
把log4j文件删了试试
