SSH實(shí)現(xiàn)的增刪改查實(shí)例

 Ethan的博客 2011-07-03

 一.整合步驟

1. 通過(guò)MyEclipse向?qū)В砑觭truts功能

2. 通過(guò)MyEclipse向?qū)?，添加Hibernate3功能：生成會(huì)話(huà)工廠的那個(gè)步驟中一定要將那個(gè)對(duì)號(hào)要去掉，不能由hibernate來(lái)生成，而是交給Spring來(lái)生成；還有就是導(dǎo)入jar包的時(shí)候選擇復(fù)制到lib目錄下這一項(xiàng)。

3. 通過(guò)MyEclipse向?qū)?，?dǎo)入實(shí)現(xiàn)Spring功能，注意導(dǎo)入jar包的時(shí)候選擇復(fù)制到lib目錄下這一項(xiàng)。

3. 利用MyEclipse反向工程的方法，以Spring<dao>生成dao對(duì)象的方式創(chuàng)建Hibernate DAO，相關(guān)POJO及其xxx.hbm.xml。

4.   DAO實(shí)現(xiàn)類(lèi)加入@Transactional標(biāo)記。

5.  修改applicationContext.xml文件，增加Spring事務(wù)管理、DAO等bean的配置。

6. 編寫(xiě)action類(lèi)。

7. 在applicationContext.xml文件中添加Action的代理bean。

8. 在struts的配置文件中，添加相應(yīng)的Action，類(lèi)名指向Spring中的代理bean，并加入<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor" />和<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
  <set-property property="contextConfigLocation"
   value="/WEB-INF/classes/applicationContext.xml" />
 </plug-in>。

9. 編寫(xiě)Jsp文件。

10. 發(fā)布web項(xiàng)目。

11. 啟動(dòng)web服務(wù)器，運(yùn)行項(xiàng)目

二.SSH實(shí)現(xiàn)關(guān)于書(shū)籍增刪改查實(shí)例

1.創(chuàng)建mysql數(shù)據(jù)庫(kù)及其表

create database book;

create table book(id int not null primary key auto_increment,bookname varchar(30),bookauthor varchar(30));
