代码下载地址：http://www.zuidaima.com/share/1760074977233920.htm

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:[email protected]">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"?>

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:

三、 开始编码:

以下是DAO部分的核心代码:

IGenericDao.java内容如下:

/**
 *
 * @author <a href="mailto:[email protected]">flustar</a>
 * @version 1.0
 * Creation date: Dec 23, 2007 6:19:21 PM
 */
 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 List<T> findByNamedQuery(String queryName, Object[] values)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。

/**

package com.firstssh.dao;

import java.util.List;

import com.firstssh.common.dao.IGenericDao;
import com.firstssh.model.User;

public interface IUserDao extends IGenericDao<User, Integer> {

    public User getUserByName(String username);

    public List<User> findAllUser();

    public User findUserByNameAndPass(String username, String password);
} 

/**

 */
package com.firstssh.dao.impl;

import java.util.List;

import com.firstssh.common.dao.GenericDao;
import com.firstssh.dao.IUserDao;
import com.firstssh.model.User;

public class UserDao extends GenericDao<User,Integer> implements IUserDao{

    public List<User> findAllUser() {

        return (List<User>)find("from User");
    }

    public User findUserByNameAndPass(String username, String password) {
        Object[] params=new Object[]{username,password};
        List<User> userList=find("from User as user where user.username=? and user.password=? ",params);
        if(userList!=null&&userList.size()>=1){
            return userList.get(0);
        }
        return null;
    }

    public User getUserByName(String username) {
        List<User> userList=find("from User as user where user.username=?",username);
        if(userList!=null&&userList.size()>=1){
            return userList.get(0);
        }
        return null;
    }

}

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！～^_^
