Struts2+spring2+hibernate3整合方案

Struts2+spring2+hibernate3整合方案
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 `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：

applicationContext-dao.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:

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！～^_^
