环境：MyEclipse 2015 Stable 2.0；struts2-core-2.3.16.1.jar等

struts.xml

<struts>                    <package name="p1" namespace="/" extends="struts-default">                    <action name="m1" class="org.ah.s2.C1" method="m1">                    <interceptor-ref name="timer" />                <interceptor-ref name="logger" />                                <result name="success" type="dispatcher">                    /success.jsp            </result>            </action>            </package>            </struts>                

有人说必须加<interceptor-ref name="defaultStack"/>，其实是不求甚解造成的。

但是，MyEclipse下，log不输出，需要配置log4j.properties，放在src下

#
# Log4J Settings for log4j 1.2.x (via jakarta-commons-logging)
#
# The five logging levels used by Log are (in order):
#
# 1. DEBUG (the least serious)
# 2. INFO
# 3. WARN
# 4. ERROR
# 5. FATAL (the most serious)

# Set root logger level to WARN and append to stdout
log4j.rootLogger=INFO, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller‘s file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%d %5p (%c:%L) - %m%n

# Print only messages of level ERROR or above in the package noModule.
log4j.logger.noModule=FATAL

# OpenSymphony Stuff
log4j.logger.com.opensymphony=INFO
log4j.logger.org.apache.struts2=INFO

# Spring Stuff
log4j.logger.org.springframework=INFO

timmer和logger的日志级别都是INFO，把级别设为INFO即可。

其他辅助文件：

index.jsp        <s:form action="m1" method="post">            <s:submit value="http://www.mamicode.com/测试Struts控件传值"></s:submit>    </s:form>                Action:        package org.ah.s2;                import com.opensymphony.xwork2.ActionSupport;                public class C1 extends ActionSupport {            public String m1() {                    return "success";    }    }        

测试一下：

2016-12-31 21:51:00,312 INFO (com.opensymphony.xwork2.interceptor.LoggingInterceptor:42) - Starting execution stack for action //m1
2016-12-31 21:51:00,354 INFO (com.opensymphony.xwork2.interceptor.LoggingInterceptor:42) - Finishing execution stack for action //m1
2016-12-31 21:51:00,354 INFO (com.opensymphony.xwork2.interceptor.TimerInterceptor:42) - Executed action [//m1!m1] took 42 ms.

MyEclippse中使用struts-default.xml中定义的拦截器（timmer,logger）
