关于jfianl log4j配置问题
@JFinal 你好，想跟你请教个问题：项目启动的时候出现的错误
log4j:ERROR A "org.apache.log4j.ConsoleAppender" object is not assignable to a "org.apache.log4j.Appender" variable. log4j:ERROR The class "org.apache.log4j.Appender" was loaded by log4j:ERROR [sun.misc.Launcher$AppClassLoader@6b97fd] whereas object of type log4j:ERROR "org.apache.log4j.ConsoleAppender" was loaded by [WebAppClassLoader=17890856@110fe28]. log4j:ERROR Could not instantiate appender named "stdout". log4j:ERROR A "org.apache.log4j.RollingFileAppender" object is not assignable to a "org.apache.log4j.Appender" variable. log4j:ERROR The class "org.apache.log4j.Appender" was loaded by log4j:ERROR [sun.misc.Launcher$AppClassLoader@6b97fd] whereas object of type log4j:ERROR "org.apache.log4j.RollingFileAppender" was loaded by [WebAppClassLoader=17890856@110fe28]. log4j:ERROR Could not instantiate appender named "logfile".
类中的log也出现问题

Log不是正常工作了么
上边这个是在log4j Error下输出的log

创建个名为log4j.properties的文件，内容如下：
log4j.rootLogger=WARN, stdout, file log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%n%-d{yyyy-MM-dd HH:mm:ss}%n[%p]-[Thread: %t]-[%C.%M()]: %m%n # Output to the File log4j.appender.file=org.apache.log4j.FileAppender log4j.appender.file.File=./my_jfinal_app.log log4j.appender.file.layout=org.apache.log4j.PatternLayout log4j.appender.file.layout.ConversionPattern=%n%-d{yyyy-MM-dd HH:mm:ss}%n[%p]-[Thread: %t]-[%C.%M()]: %m%n放在src下，确认log4j-1.2.16.jar、slf4j-api-1.6.1.jar、slf4j-log4j12-1.6.1.jar三个包的存在。。。
