Spring mvc 中使用 Log4j

1、依赖包
commons-logging-1.1.3.jar、log4j-1.2.15.jar
2、配置Web.xml

1 <context-param>
2     <param-name>log4jConfigLocation</param-name>
3     <param-value>/WEB-INF/log4j.properties</param-value>
4 </context-param>
5 <listener>
6     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
7 </listener>

3、配置log4j.properties属性文件

 1 ################ FATAL, ERROR, WARN, INFO, DEBUG
 2 log4j.rootLogger=WARN,stdout,D,E
 3 
 4 ### stdout ###
 5 log4j.appender.stdout=org.apache.log4j.ConsoleAppender
 6 log4j.appender.stdout.Target=System.out
 7 log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
 8 log4j.appender.stdout.layout.ConversionPattern= %d{ABSOLUTE} %5p %c{1}:%L - %m%n
 9 
10 ### logFile ###
11 ### save error to another file ###
12 log4j.appender.D=org.apache.log4j.DailyRollingFileAppender
13 log4j.appender.D.File=D:/logs/test-error.log
14 log4j.appender.D.Append=true
15 #error only in this file
16 log4j.appender.D.Threshold =WARN
17 log4j.appender.D.layout=org.apache.log4j.PatternLayout
18 log4j.appender.D.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss} [%t:%r] - [%p]  %m%n

4、全局异常处理，servlet-config.xml配置

 1 <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
 2     <property name="exceptionMappings">
 3         <props>
 4             <prop key="java.lang.Exception">errors/error</prop>
 5             <prop key="java.lang.Throwable">errors/err</prop>
 6         </props>
 7     </property>
 8     <property name="statusCodes">
 9         <props>
10             <prop key="errors/error">500</prop>
11             <prop key="errors/404">404</prop>
12         </props>
13     </property>
14     <!-- 设置日志输出级别，不定义则默认不输出警告等错误日志信息 -->
15     <property name="warnLogCategory" value="WARN"></property>
16     <!-- 默认错误页面，当找不到上面mappings中指定的异常对应视图时，使用本默认配置 -->
17     <property name="defaultErrorView" value="errors/error"></property>
18     <!-- 默认HTTP状态码 -->
19     <property name="defaultStatusCode" value="500"></property>
20 </bean>
21 <!-- 全局异常配置 end -->

5、代码日志写入

1 private final Log logger = LogFactory.getLog(SimplerController.class);
2 
3 logger.warn(" logger");
4 logger.error("~~info~~");

6、参考
