1、新建一个WEB工程,加入Struts2的五个核心jar包:
- freemarker-2.3.15.jar
- commons-fileupload-1.2.1.jar
- ognl-2.7.3.jar
- struts2-core-2.1.8.jar
- xwork-core-2.1.6.jar
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <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> </web-app>这个filter-class还可以写成
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
3、添加struts.xml文件:
在classpath下添加struts.xml文件,只需要一个空壳子就能让Struts跑起来,constant和package等配置可以根据实际情况慢慢添加。
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> </struts>
很多人喜欢把配置文件直接放在src目录下,反正我个人看着很不爽,所以一般我会新建一个resources目录,然后把配置文件都放进去,然后再eclipse里面把resources目录加进build path/Source里面就行了。另外,现在用Eclipse Indigo的Java EE视图,这哥们在导航栏里把全部jar都放出来了,拖动起来很是麻烦,我找了个办法,就是自己建一个User Library,让它引用到工程全部的jar包,然后让工程引用到这个User Library而不是直接引用到全部的jar包,这样导航栏就清爽多了!附上一个博客地址,上面有关于Struts2的一些基础知识: http://www.cnblogs.com/suxiaolei/
二、配置Spring:
1、依旧在web.xml里为Spring添加支持,所以web.xml就成了这样:
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <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> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <welcome-file-list> <welcome-file>insert.jsp</welcome-file> <welcome-file>welcome.jsp</welcome-file> </welcome-file-list> </web-app>
2、添加两个jar包,分别是:
- spring.jar
- commons-logging.jar
又是配置文件?当然还是放在resources里头。上面的的Spring配置使用了*通配符,所以以applicationContext-开头的xml文件都会被加载,空壳子如下:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> </beans>头好像多了点,因为加入了各种的支持。
4、Spring整合Struts:
现在可以把Spring配置到Struts里头了,先在struts.xml里面添加配置常量
<constant name="struts.objectFactory" value="spring"/>然后还要加一个jar包:struts2-spring-plugin-2.0.11.1.jar,这样就OK了!
三、配置iBatis:
在Spring的配置文件里面添加如下代码:
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName"> <value>oracle.jdbc.driver.OracleDriver</value> </property> <property name="url"> <value>jdbc:oracle:thin:@127.0.0.1:1521:orcl</value> </property> <property name="username"> <value>sa</value> </property> <property name="password"> <value>sa</value> </property> </bean> <bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> <property name="configLocation"> <value>classpath:SqlMapConfig.xml</value> </property> <property name="dataSource"> <ref local="dataSource" /> </property> </bean>添加iBatis的配置文件SqlMapConfig.xml:
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE sqlMapConfig PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-config-2.dtd"> <sqlMapConfig> <settings cacheModelsEnabled="true" enhancementEnabled="true" lazyLoadingEnabled="true" maxRequests="32" maxSessions="10" maxTransactions="5" useStatementNamespaces="true" /> </sqlMapConfig>当然还要添加ibatis-2.3.3.720.jar,这样就整合了Spring和iBatis,获取SqlMapClient只需要extends SqlMapClientDaoSupport,然后调用getSqlMapClientTemplate()就可以对数据库进行操作了。
