spring 3.2.x + struts2 + mybatis 3.x + logback 整合配置

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

267         <url>www.infosky.com.cn</url>
268     </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>
