最近在学SSH三大框架的整合,在此对他们整合时相关配置文件做一简单的模板总结,方便以后复用!
首先是web.xml配置文件,这里面就配置一些简单的监听器、过滤器,包括spring核心配置文件applicationContext.xml的路径:
web.xml
- <span style="font-size:18px;"><?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
- <listener>
- <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
- </listener>
- <context-param>
- <param-name>contextConfigLocation</param-name>
- <param-value>classpath:applicationContext.xml</param-value>
- </context-param>
- <filter>
- <filter-name>struts2</filter-name>
- <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
- </filter>
- <filter-mapping>
- <filter-name>struts2</filter-name>
- <url-pattern>/*</url-pattern>
- </filter-mapping>
- <welcome-file-list>
- <welcome-file>index.jsp</welcome-file>
- </welcome-file-list>
- </web-app></span>
接着就是spring的配置文件:applicationContext.xml,可能很多人更习惯命名为beans.xml,由于习惯使用注解方式开发,所以这个是基于annotation的配置,相对xml比较简单!由于这里面已经完成了hibernate配置文件的功能,比如配置数据库等等,所以hibernate.cfg.xml就没必要“苟活”了。
applicationContext.xml
- <span style="font-size:18px;"><?xml version="1.0" encoding="UTF-8"?>
- <beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
- xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
- xsi:schemaLocation="http://www.springframework.org/schema/beans

由于上面的配置文件涉及到运用DataSource得起数据库的连接,关系到jdbc.properties文件,所以在此举一个mysql的简单示例:
jdbc.properties
- <span style="font-size:18px;">jdbc.driverClassName=com.mysql.jdbc.Driver
- jdbc.url=jdbc:mysql://localhost:3306/ssh
- jdbc.username=root
- jdbc.password=root</span>
关于log4j的日志记录,没什么可说的,根据需要配置,简单示例如下:
log4j.properties
- <span style="font-size:18px;">### direct log messages to stdout ###
- log4j.appender.stdout=org.apache.log4j.ConsoleAppender
- log4j.appender.stdout.Target=System.out
- log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
- log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
- ### direct messages to file hibernate.log ###
- #log4j.appender.file=org.apache.log4j.FileAppender
- #log4j.appender.file.File=hibernate.log
- #log4j.appender.file.layout=org.apache.log4j.PatternLayout
- #log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
- ### set log levels - for more verbose logging change 'info' to 'debug' ###
- log4j.rootLogger=warn, stdout
- #log4j.logger.org.hibernate=info
- #log4j.logger.org.hibernate=debug
- ### log HQL query parser activity
- #log4j.logger.org.hibernate.hql.ast.AST=debug
- ### log just the SQL
- #log4j.logger.org.hibernate.SQL=debug
- ### log JDBC bind parameters ###
- #log4j.logger.org.hibernate.type=info
- #log4j.logger.org.hibernate.type=debug
- ### log schema export/update ###
- log4j.logger.org.hibernate.tool.hbm2ddl=debug
- ### log HQL parse trees
- #log4j.logger.org.hibernate.hql=debug
- ### log cache activity ###
- #log4j.logger.org.hibernate.cache=debug
- ### log transaction activity
- #log4j.logger.org.hibernate.transaction=debug
- ### log JDBC resource acquisition
- #log4j.logger.org.hibernate.jdbc=debug
- ### enable the following line if you want to track down connection ###
- ### leakages when using DriverManagerConnectionProvider ###
- #log4j.logger.org.hibernate.connection.DriverManagerConnectionProvider=trace
- </span>
至于struts.xml文件的配置就根据具体action的要求来了,比如我这次的雇员管理系统里面的简单配置如下:
struts.xml
- <span style="font-size:18px;"><?xml version="1.0" encoding="UTF-8" ?>
- <!DOCTYPE struts PUBLIC
- "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
- "http://struts.apache.org/dtds/struts-2.3.dtd">
- <struts>
- <constant name="struts.enable.DynamicMethodInvocation" value="true" />
- <constant name="struts.devMode" value="true" />
- <package name="default" namespace="/" extends="struts-default">
- <action name="employee" class="com.zzw.action.EmployeeAction">
- <result name="loginSuccess">/showAllEmployee.jsp</result>
- <result name="loginFail">/loginFail.jsp</result>
- <result name="showAll">/showAllEmployee.jsp</result>
- <result name="addSuccess">/add_success.jsp</result>
- <result name="deleteSuccess">/delete_success.jsp</result>
- <result name="goUpdatePage">/updateEmployee.jsp</result>
- <result name="updateSuccess">/updateSuccess.jsp</result>
- </action>
- </package>
- </struts>
- </span>
以上基本都是这次雇员管理系统的相关配置实例,很多地方简单化,实际上还可优化,所以仅作为参考,具体根据项目需要进行修改!
