ssh整合（1）

struts2+spring+hibernate整合

本文只是一个随笔，仅供参考，本文里面说的是一些配置

是我第一次ssh框架整合的配置，里面还有些不用的”肥肉“，我会在以后完善

首先是spring的applicationContext.xml的配置

<?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:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:jee="http://www.springframework.org/schema/jee"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd"> 
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<property name="driverClass" value="com.mysql.jdbc.Driver"/>
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/weixin"/>
<property name="user" value="root"/>
<property name="password" value="root"/>
<property name="maxPoolSize" value="40"/>
<property name="minPoolSize" value="1"/>
<property name="initialPoolSize" value="1"/>
<property name="maxIdleTime" value="20"/>
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
<list>
<value>resources/User.hbm.xml</value>
</list>
</property>

<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.jdbc.fetch_size">50</prop>
<prop key="hibernate.jdbc.batch_size">50</prop>
</props>
</property>
</bean>

<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory"/>
<!-- <property name="allowCreate" value="true"/> -->
</bean>

<bean id="dao" class="src.java.main.dao.daoImpl.BaseDaoImpl"/>
<bean id="userService" class="src.java.main.service.serviceImpl.UserServiceImpl"/>

<context:annotation-config/>
<context:component-scan base-package="src.java.main"/>

</beans>

还有另一个hibernate的配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
<class name="src.java.main.entity.User" table="db_user">
<id name="id" column="id">
<generator class="assigned"/>
</id>
<property name="name" column="name"/>
<property name="password" column="password"/>
<property name="remarks" column="remarks"/>
<property name="createUser" column="createUser"/>
<property name="createDate" column="createDate"/>
<property name="modifyUser" column="modifyUser"/>
<property name="modifyDate" column="modifyDate"/>

<!-- cascade表明操作是否从父对象级联到被关联的对象，有一下值none,save-update,delete,all,delete-orphan -->
<one-to-one name="message" cascade="all" class="src.java.main.entity.Message"/>

</class>
</hibernate-mapping>

然后因为这是hibernate的配置在spring里面配置了，所以这里只再贴下struts.xml的配置文件

<?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.ognl.allowStaticMethodAccess" value="true"/> -->
<constant name="struts.objectFactory" value="spring" />

<package name="userPackage" extends="struts-default">
<action name="login" class="src.java.main.controller.UserAction" method="login">
<result name="SUCCESS">/index.jsp</result>
</action>
</package>
</struts>

最后大招来了web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <display-name></display-name>
<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.FilterDispatcher</filter-class> -->
<!--这里是有个规则的，根据版本的不同而发生变化，这里是定义一个拦截器-->
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

<filter>
<filter-name>openSessionInViewFilter</filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
</filter-class>
<init-param>
<param-name>openSessionInViewFilter</param-name>
<param-value>/*</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>

<session-config>
<session-timeout>
30
</session-timeout>
</session-config>

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

还有一个daoImpl的代码：

public class BaseDaoImpl implements BaseDao {

@Resource(name="hibernateTemplate")
HibernateTemplate hibernateTemplate;

@SuppressWarnings("unchecked")
public Object loadById(Class clazz, Serializable id) {
return hibernateTemplate.get(clazz, id);
}

public List<?> query(String hql) {

List<?> list = null;

try {
list = hibernateTemplate.find(hql);
} catch (Exception e) {
e.printStackTrace();
}

return list;
}

@SuppressWarnings("deprecation")
public List<?> listAll(String clazz, int pageNo, int pageSize) {
final int pNo = pageNo;
final int pSize = pageSize;
final String hqlStr = "from "+clazz+" as c order by c.id desc";
List<?> list = hibernateTemplate.executeFind(
new HibernateCallback<Object>(){
public Object doInHibernate(Session sn) throws
HibernateException,SQLException{
Query query = sn.createQuery(hqlStr);
query.setMaxResults(pSize);
query.setFirstResult((pNo - 1)*pSize);

List<?> result = query.list();
if(!Hibernate.isInitialized(result)){
Hibernate.initialize(result);
}

return result;
}
});

return list;
}

public void saveOrObject(Object obj) {
hibernateTemplate.saveOrUpdate(obj);
}

}

这只是个开始
