SSI整合以及缓存的配置（struts2.2.1.1 + spring3.0.1 + ibatis2.3.0.677）

我使用的是myEclipse8.6版本

1.首先导入struts2的jar包和插件包（在下载的struts-2.2.1.1-all/struts-2.2.1.1/apps/struts2-blank/WEB-INF/lib下所有jar包 和struts-2.2.1.1-all/struts-2.2.1.1/lib/struts2-spring-plugin-2.2.1.1.jar）

2.使用myEclipse8.6自带的功能引入spring3.0的jar包

3.加入ehcache-1.6.0.jar，ibatis-2.3.0.677.jar，（网上自己下载）

ojdbc14.jar，org.springframework.context.support-3.0.0.RELEASE.jar

接下来是配置文件：

web.xml:

<!-- 读取spring配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:applicationContext.xml
classpath:cacheContext.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- struts 过滤器 -->
<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>

struts.xml:

因为有struts2-spring-plugin-2.2.1.1.jar

所有我可以写Action的全路径（com.jungle.action.UserAction）而不用在applicationContext.xml中配置Action

<struts>
<constant name="struts.devMode" value="true" />
<package name="user" extends="struts-default" namespace="/user">
<action name="user" class="com.jungle.action.UserAction">
<result>/index.jsp</result>
</action>
</package>
</struts>

applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>

</property> </bean>

<!-- 支持元注释 -->
<context:annotation-config />

<!-- 扫描包目录 -->
<context:component-scan base-package="com"></context:component-scan>

<!-- 数据源 -->

<property name="url" value="jdbc:oracle:thin:@localhost:1521:oracle" />

<property name="password" value="chenl" />
</bean>
<!-- 大字段 -->
<bean id="lobHandler" class="org.springframework.jdbc.support.lob.DefaultLobHandler" />

<!-- ibatis 必须 因为需要读取配置文件 classpath:sqlmap-config.xml -->
<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="configLocation" value="classpath:sqlmap-config.xml" />
<property name="dataSource" ref="dataSource" />
<property name="lobHandler" ref="lobHandler"></property>
</bean>

<!-- 1.第一种方式(必须使用注解的方式@Resource) ： 自定义一些方法 如queryForString,queryForBoolean等 -->
<bean id="mySqlMapClientDaoSupport" class="com.jungle.dao.common.MySqlMapClientDaoSupport">
<property name="dataSource" ref="dataSource" />
<property name="sqlMapClient" ref="sqlMapClient" />
</bean>

<!-- 2.第二种方式(必须使用注解的方式@Resource)，使用get,set方式需要使用接口的方式才行-->
<bean id="sqlMapClientTemplate" class="org.springframework.orm.ibatis.SqlMapClientTemplate">
<property name="dataSource" ref="dataSource" />
<property name="sqlMapClient" ref="sqlMapClient" />
</bean>

</beans>

ibatis的配置文件（sqlmap-config.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">

<!-- ibatis配置文件 -->
<sqlMapConfig>
<settings
cacheModelsEnabled="true"
enhancementEnabled="true"
lazyLoadingEnabled="true"
errorTracingEnabled="true"
maxRequests="512"
maxSessions="128"
maxTransactions="32"
useStatementNamespaces="true"
/>

<!-- 引入xml文件 -->
<sqlMap resource="com/jungle/dao/config/common.ibatis.xml" />
</sqlMapConfig>

common.ibatis.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd">

<!-- 例子 -->
<sqlMap namespace="common">
<typeAlias alias="user" type="com.jungle.dao.entity.User" />

<resultMap id="resultUser" class="com.jungle.dao.entity.User">
<result column="NID" property="nid" />
<result column="PASSWORD" property="password" />
<result column="USERNAME" property="username" />
</resultMap>

<!-- 查询一个User-->
<select id="getSingleUser" parameterClass="string" resultMap="resultUser">
<!--[CDATA[
select nid,username,password
from t_user
where nid = #nid#
ORDER BY nid
]]>
</select>

<!-- 查询出列表 -->
<select id="getUserList" resultMap="resultUser">
<![CDATA[
select nid,username,password
from t_user
ORDER BY nid
]]-->
</select>
</sqlMap>

因为web.xml中有加入classpath:cacheContext.xml 这是缓存的文件

所以必须在src下加入cacheContext.xml和ehcache-application.xml两个文件

ehcache-application.xml:(这个文件中最好不要加中文和注释否则可能会有问题)

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">
<diskStore path="java.io.tmpdir"/>
<cacheManagerEventListenerFactory class="" properties=""/>
<defaultCache maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" diskSpoolBufferSizeMB="30" maxElementsOnDisk="10000000" diskPersistent="false" diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU"/>

<cache name="coreCache"
maxElementsInMemory="3" eternal="true" overflowToDisk="false"/>


</ehcache>

cacheContext.xml：

<?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:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-2.5.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-2.5.xsdhttp://www.springframework.org/schema/jeehttp://www.springframework.org/schema/jee/spring-jee-2.5.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-2.5.xsd"
>

<!--缓存-->
<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<property name="configLocation">
<value>classpath:ehcache-application.xml</value>
</property>
</bean>

<!--核心缓存
使用时:
@Resource
private Cache coreCache-->

<bean id="coreCache" class="org.springframework.cache.ehcache.EhCacheFactoryBean">
<property name="cacheManager">
<ref local="cacheManager"/>
</property>
<property name="cacheName">
<value>coreCache</value>
</property>
</bean>

</beans>

配置文件完成了。

接下来看看如何使用：

UserDaoImpl:

@Component("userDao")
public class UserDaoImpl implements UserDao {
// 使用get,set方式不行 ，因为SqlMapClientTemplate不是接口
@Resource
private SqlMapClientTemplate sqlMapClientTemplate;

@Resource
private MySqlMapClientDaoSupport mySqlMapClientDaoSupport;

UserAction:

public class UserAction extends ActionSupport {
@Resource
private UserDao userDao;

@Override
public String execute() throws Exception {
System.out.println(userDao.getUser("1"));
return SUCCESS;
}
}

PS:原来是有加xml的格式的 可是IE一查看就卡死 所以这里XML才全部没有套格式。
