MyEclipse SSH初体验
17:44
SSH即Struts+spring+hibernate框架.
本次体验使用的Struts2+spring3+hibernate3
1，创建ssh工程.
2,添加hibernate访问数据库
Windows->show view->dbExplorer
●创建db连接，本次体验使用mysql作为体验数据库，其他数据库应该类似
●选择配置的连接右键->openconnection建立数据库连接.
●添加hibernate配置:两种方式:POJODao/SpringDao两者没有太大差异只是在配置时略有不同)
如果使用Spring Dao则需要先引用Spring支持Library
右键project：MyEclipse->Add Spring Cap….
一路默认即可
添加Hibernate支持:Project->右键->MyEclipse->add hibernate cap…
Next如果Pojo则选择Hibernate.xfg.xml，如果SpringDao则选择applicatonContext.xml
根据需要选择xml文件
选择数据库连接配置
选择实体类生成文件存储路径和包
Finish完成Hibernate配置
添加Spring persistence jdbc libraries工程右键->properties->java build path->MyEclipse->spring xxx persistence jdbc libraries
●生成HibernateDao实体数据
数据库连接中选择schma->Table右键->Hibernate Reverse Engineering来生成Dao
如果为pojodao选择basicdao
如果springdao选择spring dao
next在id generator中选择native根据需要选择one-to-many/many-to-one等选项
Next->finish则在相应的package中将生成对应的xxxdao.java,xxx.hbm.xml等文件
●添加业务层逻辑
添加相应处理接口这里使用IOwenerService接口，添加getOwners()
public interface IOwnerService {
public List getOwners();
}
添加OwenerService继承自IOwenerService，然后添加相应的Dao对象作为OwenerService的成员。
然后生成getter/Setter
public class OwnerService implements IOwnerService {
public OwnersDAO getOwnerDao() {
return ownerDao;
}
public void setOwnerDao(OwnersDAO ownerDao) {
this.ownerDao = ownerDao;
}
private OwnersDAO ownerDao; //根据需要变更
public List getOwners() {
// TODO Auto-generated method stub
return ownerDao.findAll();
}
}
●添加表现层处理
Project->右键->Add Struts cap….
选择struts2 core/struts 2 spring(从struts到spring的连接必须选择)
Finish完成Struts的添加
添加页面以及相应的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;
}
}
●Index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
●List.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

●xml配置
Struts.xml配置如下
Applicationcontext.xml
xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> value="com.mysql.jdbc.Driver"> org.hibernate.dialect.MySQLDialect
>
Web.xml配置 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 至此，已经完成了ssh架构的初次体验。
