与前面的一篇mybatis 3.2.7 与 spring mvc 3.x、logback整合 相比，只是web层的MVC前端框架，从spring mvc转换成struts 2.x系列，变化并不大
一、pom.xml 配置

</organization> 269 270 </project>
主要是maven的关键依赖项，不要漏掉就行
二、web.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 5 6 <display-name>struts2-helloworld</display-name> 7 8 <context-param> 9 <param-name>logbackConfigLocation</param-name> 10 <param-value>classpath:logback.xml</param-value> 11 </context-param> 12 <listener> 13 <listener-class>com.cnblogs.yjmyzz.util.LogbackConfigListener</listener-class> 14 </listener> 15 16 <context-param> 17 <param-name>contextConfigLocation</param-name> 18 <param-value>classpath:spring.xml</param-value> 19 </context-param> 20 <listener> 21 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 22 </listener> 23 24 <filter> 25 <filter-name>struts2</filter-name> 26 <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> 27 <!-- <init-param> 28 <param-name>loggerFactory</param-name> 29 <param-value>com.opensymphony.xwork2.util.logging.slf4j.Slf4jLoggerFactory</param-value> 30 </init-param> --> 31 </filter> 32 33 <filter-mapping> 34 <filter-name>struts2</filter-name> 35 <url-pattern>/*</url-pattern> 36 </filter-mapping> 37 38 <welcome-file-list> 39 <welcome-file>index.html</welcome-file> 40 </welcome-file-list> 41 42 </web-app>
注意上面被注释的一段：虽然xwork提供了com.opensymphony.xwork2.util.logging.slf4j.Slf4jLoggerFactory这个类用于整合SLF4J兼容的各种log实现（比如：logback），但我在实际中发现，logback.xml配置文件始终不起作用，运行时一直加载的是logback的默认配置，所以建议改用自已开发的LogbackConfigListener（代码已经在上一篇2.2中给出）
解释：web.xml中主要干了3件事：监听logback配置文件、监听Spring配置文件、注册Struts2的入口Filter
三、weblogic.xml与jboss-deployment-structure.xml
在weblogic下以war包部署时，由于war是一个压缩包，不会自动展开，所以一些依赖于物理文件路径的代码，可能会有问题，比如报一些：
java.lang.IllegalStateException: Cannot set web app root system property when WAR file is not expanded
之类的错误，解决办法：在WEB-INF下放置一个名为weblogic.xml的文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/90"> 3 <session-descriptor> 4 <cookie-path>/</cookie-path> 5 </session-descriptor> 6 <container-descriptor> 7 <prefer-web-inf-classes>true</prefer-web-inf-classes> 8 <show-archived-real-path-enabled>true</show-archived-real-path-enabled> 9 </container-descriptor> 10 <context-root>struts2-helloworld</context-root> 11 <!-- <library-ref> <library-name>acmlibrary</library-name> </library-ref> --> 12 </weblogic-web-app>
注意：第8行<show-archived-real-path-enabled>true</show-archived-real-path-enabled>，这里告诉weblogic显示war包的真实路径，以便相关代码在取文件路径时能拿到物理路径。
同样，如果部署在jboss下时，由于jboss默认提供的SLF4J的实现与logback有冲突，需要在WEB-INF下放置jboss-deployment-structure.xml，排除jboss自带的jar包
1 <?xml version="1.0" encoding="UTF-8"?> 2 <jboss-deployment-structure> 3 <deployment> 4 <exclusions> 5 <module name="org.slf4j" /> 6 <module name="org.slf4j.impl" /> 7 <module name="org.slf4j.jcl-over-slf4j" /> 8 <module name="org.slf4j.ext" /> 9 </exclusions> 10 </deployment> 11 </jboss-deployment-structure>
三、struts2中的Action处理及相关配置
先来一个Action的基类
1 package com.cnblogs.yjmyzz.action; 2 3 import org.slf4j.Logger; 4 import org.slf4j.LoggerFactory; 5 6 import com.opensymphony.xwork2.ActionSupport; 7 8 public class BaseAction extends ActionSupport { 9 10 private static final long serialVersionUID = -4320398837758540242L; 11 protected Logger logger = LoggerFactory.getLogger(this.getClass()); 12 13 }
虽然ActionSupport中有一个LOG的实例变量，但经实践，发现用LOG对象记录的日志，不受logback.xml配置文件控制，所以这里定义一个logger，以便其子类都可以正常使用logback。
其它Action都继承它
1 package com.cnblogs.yjmyzz.action; 2 3 import org.springframework.stereotype.Component; 4 5 @Component("HelloWorldAction") 6 public class HelloWorldAction extends BaseAction { 7 8 private static final long serialVersionUID = -8827776224243873974L; 9 10 private String message; 11 12 public String execute() throws Exception { 13 14 //log sample 15 for (int i = 0; i < 1000; i++) { 16 logger.trace("logback->trace" + i); 17 logger.debug("logback->debug" + i); 18 logger.info("logback->info" + i); 19 logger.warn("logback->warn" + i); 20 logger.error("logback->error" + i); 21 } 22 23 return SUCCESS; 24 } 25 26 public String sayHi() throws Exception { 27 message = "welcome to SSH!"; 28 return SUCCESS; 29 } 30 31 public String getMessage() { 32 return message; 33 } 34 35 public void setMessage(String message) { 36 this.message = message; 37 } 38 39 }
注：类上面加上@Component注解，配合这个注释，Spring.xml主配置文件里，配置自动扫描，就不用手动一个一个bean的写配置了
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" 4 xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xsi:schemaLocation=" 7 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd 8 http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 9 http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd 10 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 11 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd" 12 default-autowire="byName"> 13 14 <context:component-scan base-package="com.cnblogs.yjmyzz"> 15 </context:component-scan> 16 17 <import resource="spring-datasource.xml" /> 18 </beans>
运行时Spring会自动注入所有Action的实例，这样在配置struts.xml时，就可以用@Component后面name值来代替完整Action类名，简化配置
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE struts PUBLIC 3 "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" 4 "http://struts.apache.org/dtds/struts-2.0.dtd"> 5 <struts> 6 7 <package name="home" namespace="/home" extends="default"> 8 9 <action name="HelloWorld_*" method="{1}" class="HelloWorldAction"> 10 <result>/WEB-INF/views/home/HelloWorld.jsp</result> 11 </action> 12 13 </package> 14 </struts>
注：第9行<action name="HelloWorld_*" method="{1}" class="HelloWorldAction">的class，如果没有Spring，应该写完整路径com.cnblogs.yjmyzz.action.HelloWorldAction，但现在只需要写HelloWorldAction就行了.
四、MyBatis配置
这跟上一篇完全相同，就不再重复了
五、logback.xml配置
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <configuration scan="true" scanPeriod="1800 seconds" 3 debug="false"> 4 5 <property name="USER_HOME" value="logs" /> 6 <property scope="context" name="FILE_NAME" value="test-logback" /> 7 8 <timestamp key="byDay" datePattern="yyyy-MM-dd" /> 9 10 <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> 11 <encoder> 12 <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n 13 </pattern> 14 </encoder> 15 </appender> 16 17 <appender name="file" 18 class="ch.qos.logback.core.rolling.RollingFileAppender"> 19 <file>${USER_HOME}/${FILE_NAME}.log</file> 20 21 <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> 22 <fileNamePattern>${USER_HOME}/${byDay}/${FILE_NAME}-${byDay}-%i.log.zip 23 </fileNamePattern> 24 <minIndex>1</minIndex> 25 <maxIndex>10</maxIndex> 26 </rollingPolicy> 27 28 <triggeringPolicy 29 class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> 30 <maxFileSize>5MB</maxFileSize> 31 </triggeringPolicy> 32 <encoder> 33 <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-4relative [%thread] %-5level %logger{150} - %msg%n 34 </pattern> 35 </encoder> 36 </appender> 37 38 <logger name="com.cnblogs.yjmyzz" level="debug" additivity="true"> 39 <appender-ref ref="file" /> 40 </logger> 41 42 <root level="debug"> 43 <appender-ref ref="STDOUT" /> 44 </root> 45 </configuration>
