Answer 1

contextDestroyed()销毁上下文对象

Answer 2

Tomact5.0 下面的日志包含其下左右项目的日志信息请问怎么在工程下设置一下，把工程日志单独存放到一个文件是不是涉及到log4j什么的？  

Answer 3

打印日志用这个
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

Answer 4

工程日志的话，你可以在你的启动类， 或者第一个会进入的类中加上 log4j 的配置

Answer 5

### global config ###
# log level: DEBUG<INFO<WARN<ERROR<FATAL
log4j.rootLogger=INFO, console, file### appender of console ###
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=[%-5p  %5r %c] -> %m%n### appender of file ###
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=example.log
log4j.appender.file.MaxFileSize=5KB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=[%-5p  %5r  %d{MM-dd HH\:mm\:ss}  %c{5}] -> %m%nlog4j配置
