二、web.xml配置

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"id="WebApp_ID" version="3.0"><display-name>StoreManagerSystem-MVC</display-name><welcome-file-list><welcome-file>index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file>index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file>default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list><!-- 配置log4j --><context-param><param-name>log4jConfigLocation</param-name><param-value>classpath:log4j.properties</param-value></context-param><context-param><param-name>log4jRefreshInterval</param-name><param-value>3000</param-value></context-param><!-- 编码过滤器 --><!-- 统一采用UTF-8编码 --><filter><filter-name>encoding</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param></filter><filter-mapping><filter-name>encoding</filter-name><url-pattern>/</url-pattern></filter-mapping><!-- Spring配置文件 --><!-- Spring -xml --><servlet><servlet-name>spring</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/spring-servlet.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>spring</servlet-name><url-pattern>/</url-pattern></servlet-mapping><!-- 指定log4j的listener --><listener>          <listener-class>              org.springframework.web.util.Log4jConfigListener          </listener-class>      </listener>  <!-- <listener> --><!-- <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> --><!-- </listener> --></web-app>

说明几点：

1、日志采用log4j工具输出，包括输出到Console和本地文件，log4j.properties文件位于classpath路径下面，所以在Web.xml中需要加载该文件，包括配置文件的路径和加载该文件的listener

log4j.properties内容如下

###Root Logger DEBUG < INFO < WARN < ERROR < FATALlog4j.rootLogger=INFO,console,dailyFile,logFilelog4j.additivity.org.apache=true### console log4j.appender.console=org.apache.log4j.ConsoleAppenderlog4j.appender.console.Threshold=INFOlog4j.appender.console.ImmediateFlush=truelog4j.appender.console.Target=System.outlog4j.appender.console.layout=org.apache.log4j.PatternLayoutlog4j.appender.console.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n### logFilelog4j.appender.logFile=org.apache.log4j.FileAppenderlog4j.appender.logFile.Threshold=INFOlog4j.appender.logFile.ImmediateFlush=truelog4j.appender.logFile.Append=truelog4j.appender.logFile.File=E:/ManagerSystem/logs/log/log.log4jlog4j.appender.logFile.layout=org.apache.log4j.PatternLayoutlog4j.appender.logFile.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n### rollingFilelog4j.appender.rollingFile=org.apache.log4j.RollingFileAppenderlog4j.appender.rollingFile.Threshold=INFOlog4j.appender.rollingFile.ImmediateFlush=truelog4j.appender.rollingFile.Append=truelog4j.appender.rollingFile.File=E:/ManagerSystem/logs/rolling/log.log4jlog4j.appender.rollingFile.MaxFileSize=200KBlog4j.appender.rollingFile.MaxBackupIndex=50log4j.appender.rollingFile.layout=org.apache.log4j.PatternLayoutlog4j.appender.rollingFile.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n### dailyFile## '.'yyyy-MM           # every month## '.'yyyy-ww           # every week## '.'yyyy-MM-dd        # every day## '.'yyyy-MM-dd-a      # twice a day## '.'yyyy-MM-dd-HH     # every hour## '.'yyyy-MM-dd-HH-mm  # every minutelog4j.appender.dailyFile=org.apache.log4j.DailyRollingFileAppenderlog4j.appender.dailyFile.Threshold=DEBUGlog4j.appender.dailyFile.ImmediateFlush=truelog4j.appender.dailyFile.Append=truelog4j.appender.dailyFile.File=E:/ManagerSystem/logs/daily/log.log4jlog4j.appender.dailyFile.DatePattern='.'yyyy-MM-ddlog4j.appender.dailyFile.layout=org.apache.log4j.PatternLayoutlog4j.appender.dailyFile.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n### spring default levellog4j.logger.org.springframework=INFO### hibernate default levellog4j.logger.org.hibernate=INFO### apachelog4j.logger.org.apache=ERRORlog4j.logger.net.sf.ehcache=ERROR### socket#log4j.appender.socket=org.apache.log4j.RollingFileAppender#log4j.appender.socket.RemoteHost=localhost#log4j.appender.socket.Port=5001#log4j.appender.socket.LocationInfo=true### Set up for Log Factor 5#log4j.appender.socket.layout=org.apache.log4j.PatternLayout#log4j.appender.socket.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n### Log Factor 5 Appender#log4j.appender.LF5_APPENDER=org.apache.log4j.lf5.LF5Appender#log4j.appender.LF5_APPENDER.MaxNumberOfRecords=2000### Email#log4j.appender.mail=org.apache.log4j.net.SMTPAppender#log4j.appender.mail.Threshold=FATAL#log4j.appender.mail.BufferSize=10#log4j.appender.mail.From = [e-mail]#log4j.appender.mail.SMTPHost=mail.com#log4j.appender.mail.Subject=Log4J Message#log4j.appender.mail.To= [e-mail]#log4j.appender.mail.layout=org.apache.log4j.PatternLayout#log4j.appender.mail.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n### Database#log4j.appender.database=org.apache.log4j.jdbc.JDBCAppender#log4j.appender.database.URL=jdbc:mysql://localhost:3306/test#log4j.appender.database.driver=com.mysql.jdbc.Driver#log4j.appender.database.user=root#log4j.appender.database.password=#log4j.appender.database.sql=INSERT INTO LOG4J (Message) VALUES('=[%-5p] %d(%r) --> [%t] %l: %m %x %n')#log4j.appender.database.layout=org.apache.log4j.PatternLayout#log4j.appender.database.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n### Appender#log4j.appender.im = net.cybercorlin.util.logger.appender.IMAppender#log4j.appender.im.host = mail.cybercorlin.net#log4j.appender.im.username = username#log4j.appender.im.password = password#log4j.appender.im.recipient = [e-mail]#log4j.appender.im.layout=org.apache.log4j.PatternLayout#log4j.appender.im.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n

2、项目统一采用UTF-8编码

3、Spring核心配置

<span style="white-space:pre"></span><servlet><servlet-name>spring</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/spring-servlet.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>spring</servlet-name><url-pattern>/</url-pattern></servlet-mapping>

该配置的作用是，加载位于<span style="font-family: Arial, Helvetica, sans-serif;">/WEB-INF目录下的</span><span style="font-family: Arial, Helvetica, sans-serif;">spring-servlet.xml文件，并将所有请求交给</span><span style="font-family: Arial, Helvetica, sans-serif;">DispatcherServlet处理。至于其详细的作用，请自行了解。</span>

三、spring-servlet.xml配置

该配置问主要配置，包括项目所要用到的数据源（database）、操作数据库的session，管理session的事物（transaction），Bean、拦截器（Interceptor）、AOP以及视图解析器。

详细配置如下

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

说明

1、

<span style="white-space:pre"></span><!-- 注解方式配置事物 --><!-- ====================================== --><!-- <tx:annotation-driven transaction-manager="transactionManager" /> --><!-- AOP方式配置事物 --><!-- ====================================== --><tx:advice id="transactionAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="get*" propagation="REQUIRED" read-only="true" /><tx:method name="add*" propagation="REQUIRED" /><tx:method name="delete" propagation="REQUIRED" /><tx:method name="*" propagation="REQUIRED" /></tx:attributes></tx:advice><aop:config><aop:pointcut id="transactionPointcut"expression="execution(* com.kl.napchen.store.impl..*.*(..))" /><aop:advisor pointcut-ref="transactionPointcut"advice-ref="transactionAdvice" /></aop:config>

采用注解的方式和采用AOP的方式都可以达到相同的目的。采用注解方式这需要用@transition注解标注service。

拦截器也有两种配置方法，具体见xml文件和注释，在本项目采取的方法中，其中的property属性需要注意，它采用一个list来配置该拦截器不需要拦截的Uri。因为拦截器并没有提供反向排除的配置方式，故先拦截所有，然后在拦截器中剔除部分。详细的剔除代码将在拦截器的Java代码中给出。

以上就是该项目的配置文件。
