SSH即Struts+spring+hibernate架構.

本次體驗使用的Struts2+spring3+hibernate3

1，建立ssh工程.

2,添加hibernate訪問資料庫

Windows->show view->dbExplorer

●建立db串連，本次體驗使用mysql作為體驗資料庫，其他資料庫應該類似

●選擇配置的串連右鍵->openconnection建立資料庫連接.

●添加hibernate配置:兩種方式:POJODao/SpringDao兩者沒有太大差異只是在配置時略有不同)

如果使用Spring Dao則需要先引用Spring支援Library

右鍵project：MyEclipse->Add Spring Cap….

一路預設即可

添加Hibernate支援:Project->右鍵->MyEclipse->add hibernate cap…

Next如果Pojo則選擇Hibernate.xfg.xml，如果SpringDao則選擇applicatonContext.xml

根據需要選擇xml檔案

選擇資料庫連接配置

選擇實體類組建檔案儲存路徑和包

Finish完成Hibernate配置

添加Spring persistence jdbc libraries工程右鍵->properties->java
build path->MyEclipse->spring xxx persistence jdbc libraries

●產生HibernateDao實體資料

資料庫連接中選擇schma->Table右鍵->Hibernate Reverse Engineering來產生Dao

如果為pojodao選擇basicdao

如果springdao選擇spring dao

next在id
generator中選擇native根據需要選擇one-to-many/many-to-one等選項

Next->finish則在相應的package中將產生對應的xxxdao.java,xxx.hbm.xml等檔案

●添加業務層邏輯

添加相應處理介面這裡使用IOwenerService介面，添加getOwners()

public interface IOwnerService {

public List getOwners();

}

 

添加OwenerService繼承自IOwenerService，然後添加相應的Dao對象作為OwenerService的成員。

然後產生getter/Setter

public class OwnerService
implements IOwnerService {

public OwnersDAO getOwnerDao() {

return ownerDao;

}

public void
setOwnerDao(OwnersDAO ownerDao) {

this.ownerDao = ownerDao;

}

private OwnersDAO ownerDao; //根據需要變更

public List getOwners() {

// TODO Auto-generated method
stub                

return ownerDao.findAll();

}

}

●添加表現層處理

Project->右鍵->Add Struts cap….

 

選擇struts2 core/struts 2 spring(從struts到spring的串連必須選擇)

Finish完成Struts的添加

 

添加頁面以及相應的action

●action

public
class ListAction extends ActionSupport {

public
Collection getOwners() {

return
owners;

}

public void
setOwenrSrv(IOwnerService owenrSrv) {

this.owenrSrv = owenrSrv;

}

private IOwnerService owenrSrv;

private
Collection owners;

/**

 * @return

 */

public
String execute() {

//
TODO Auto-generated method stub

owners
= this.owenrSrv.getOwners();

return
SUCCESS;

}

}
