最近闲来无事可做，于是开始学习struts2。Struts2和struts1、webwork2有什么区别我也不说了，网上有很多这方面的资料。以前在项目中从未使用过struts，一直使用spring+hibernate，现在既然学习了Struts，也不能浪费，于是乎开始琢磨着怎么整合这3个框架。整合原理以spring为容器，管理hibernate的DAO和Struts2的Action。
一、 准备工作
Struts2.06+spring2.5+hibernate3.2+jdk6.0+myeclipse6.0+tomcat5.5+mysql5.0
以上是整合的原料。下面以一个注册登陆的例子来开始我们的整合过程。
这个例子很简单，下面是它的sql脚本内容:
CREATE TABLE `zuidaima_user` ( `userid` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(20) NOT NULL, `password` varchar(16) NOT NULL, `email` varchar(30) NOT NULL, PRIMARY KEY (`userid`) ) ENGINE=InnoDB DEFAULT CHARSET=utf-8;
二、 开始行动
包结构可以参考下图
图一
图二
图三
1) Struts部分:建立struts.xml和struts.properties
Struts.xml内容如下：
<? 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>
<package name ="user_curd" extends ="struts-default" >
<global-results>
<!-- 下面定义的结果对所有的Action都有效 -->
<result name ="exception"> /error.jsp </result>
</global-results>
<global-exception-mappings>
<!-- 指Action抛出Exception异常时，转入名为exception的结果。 -->
<exception-mapping exception ="java.lang.Exception" result ="exception" />
</global-exception-mappings>
<action name ="Login" class ="LoginAction">
<result name ="success"> /success.jsp </result>
<result name ="input"> /login.jsp </result>
</action>
<action name ="Regist" class ="RegistAction">
<result name ="success"> /success.jsp </result>
<result name ="input"> /regist.jsp </result>
</action>
</package>
</struts>
Struts.properties内容如下:
struts.devMode = false struts.enable.DynamicMethodInvocation = true struts.i18n.reload = true struts.ui.theme =xhtml struts.locale = zh_CN struts.i18n.encoding = UTF- 8 struts.objectFactory = spring struts.objectFactory.spring.autoWire = name struts.serve.static.browserCache = false struts.url.includeParams = none
2) 建立User.java和User.hbm.xml、jdbc.properties：
User.java内容如下:
/**
*
* @author <a href="mailto:flustar2008@163.com">flustar</a>
* @version 1.0
* Creation date: Dec 23, 2007 1:55:28 PM
*/
package com.firstssh.model;
import java.io.Serializable;
public class User implements Serializable {
private int id;
private String username;
private String password;
private String email;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
User.hbm.xml内容:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping
package="com.firstssh.model">
<class name="User" table="User">
<id name="id" column="userid">
<generator class="identity" />
</id>
<property name="username"
column="username"
not-null="true"
length="20"
/>
<property name="password"
column="password"
not-null="true"
length="16" />
<property name="email"
column="email"
not-null="true"
length="30"/>
</class>
</hibernate-mapping>
jdbc.properties内容如下:
datasource.type = mysql datasource.driverClassName = com.mysql.jdbc.Driver datasource.url = jdbc:mysql://localhost: 3306 /test?useUnicode = true&characterEncoding = UTF- 8 datasource.username = root datasource.password = 123456 datasource.maxActive = 10 datasource.maxIdle = 2 datasource.maxWait = 120000 datasource.whenExhaustedAction = 1 datasource.validationQuery = select 1 from dual datasource.testOnBorrow = true datasource.testOnReturn = false c3p0.acquireIncrement = 3 c3p0.initialPoolSize = 3 c3p0.idleConnectionTestPeriod = 900 c3p0.minPoolSize = 2 c3p0.maxPoolSize = 50 c3p0.maxStatements = 100 c3p0.numHelperThreads = 10 c3p0.maxIdleTime = 600 hibernate.dialect = org.hibernate.dialect.MySQLInnoDBDialect #hibernate.dialect = org.hibernate.dialect.MySQLMyISAMDialect hibernate.jdbc.batch_size = 25 hibernate.jdbc.fetch_size = 50 hibernate.show_sql = true hibernate.connection.release_mode = after_transaction
3) Spirng部分:为了清晰把Spring的配置文件拆分成以下几部分applicationContext-dao.xml、appliationContext-service.xml、applicationContext-hibernate.xml、action-servlet.xml。
applicationContext-hibernate.xml内容：
<?xml version="1.0" encoding="UTF-8"?>

</property>
</bean>
</beans>
applicationContext-dao.xml内容:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">

以上几个xml文件的内容暂且不要理会，继续往下看，你就自动明白的，不用我解释。
4）日志部分:log4j.properties 、commons-logging.properties
log4j.properties内容:
# For JBoss: Avoid to setup Log4J outside $JBOSS_HOME/server/default/deploy/log4j.xml!
# For all other servers: Comment out the Log4J listener in web.xml to activate Log4J.

三、 开始编码:
以下是DAO部分的核心代码:
IGenericDao.java内容如下:
/**

*/
package com.firstssh.common.dao;
import java.io.Serializable;
import java.util.Collection;
import java.util.List;
import org.hibernate.LockMode;
import org.hibernate.criterion.DetachedCriteria;
import org.springframework.dao.DataAccessException;
import com.firstssh.common.util.PaginationSupport;
public interface IGenericDao <T, ID extends Serializable> {
public T load(ID id) throws DataAccessException;
public T get(ID id)throws DataAccessException;
public boolean contains(T t) throws DataAccessException;
public void refresh(T t, LockMode lockMode) throws DataAccessException;
public void refresh(T t) throws DataAccessException;
public Serializable save(T t) throws DataAccessException;
public void saveOrUpdate(T t) throws DataAccessException;
public void saveOrUpdateAll(Collection<T> entities)
throws DataAccessException;
public void update(T t, LockMode lockMode) throws DataAccessException;
public void update(T t) throws DataAccessException;
public void delete(T t, LockMode lockMode) throws DataAccessException;
public void delete(T t) throws DataAccessException;
public void deleteAll(Collection<T> entities) throws DataAccessException;
public List<T> find(String queryString, Object value)
throws DataAccessException;
public List<T> find(String queryString, Object[] values)
throws DataAccessException;
public List<T> find(String queryString) throws DataAccessException;
public List<T> list()throws DataAccessException;
public List<T> findByNamedQuery(String queryName)throws DataAccessException ;
public List<T> findByNamedQuery(String queryName, Object value)throws DataAccessException ;

public PaginationSupport findPageByCriteria(
final DetachedCriteria detachedCriteria, final int pageSize,
final int startIndex);
public PaginationSupport findPageByQuery(final String hql,
final String countHql, final int pageSize, final int startIndex);
}
GenericDao.java内容如下:

呵呵，使用了泛型,以后每建立一个Dao都要建立相应的dao接口和实现类，如本例中的IUserDao和UserDao。

还有好多文件的代码没有贴出来，我实在不忍心再复制、粘贴下去了（浪费大家那么多时间）,有兴趣的可以下载这个例子的源代码（由于这个例子牵涉的jar包比较大我就不把它们放进去了），我想以上这些文件的内容我就不用解释了，因为大家都学过SSH。本人初次整合它们，并没有使用这个整合方案做过项目，一定还有某些方面考虑的还不是太成熟，哪位大侠看了，还请多多批评指正，也希望谁有更好的整合方案，也共享一下，大家共同进步，共同提高！～^_^
