SSH项目搭建步骤

SSH项目搭建步骤按顺序添加功能支持：1、Spring3------------配置文件applicationContext.xml2、Hibernate3.3------配置文件hibernate.cfg.xml3、Struts2-------------配置文件struts.xml一、建立web项目二、添加spring支持选择spring所需的jar包下一步产生spring配置文件applicationContext.xml三、给项目添加Hibernate支持这里询问是否将hibernate和spring的配置文件合并四、给项目添加struts2支持产生的配置文件：五、配置启动环境：a)配置web.xml，让启动时能加载spring容器环境b)配置struts.xml，让spring来管理其Actionc)配置hibernate.cfg.xml（非必须）六、创建包com.scce.bean存放实体类：package com.scce.bean;import javax.persistence.Entity;import javax.persistence.GeneratedValue; import javax.persistence.Id;//标识为实体类@Entitypublic class Employee {private int empId;private int empDeptId;private String empName;private String empPwd;//标识主键列及生成方式，这里自增@Id@GeneratedValuepublic int getEmpId() {return empId;}public void setEmpId(int empId) {this.empId = empId;}public int getEmpDeptId() {return empDeptId;}public void setEmpDeptId(int empDeptId) { this.empDeptId = empDeptId;}public String getEmpName() {return empName;}public void setEmpName(String empName) { this.empName = empName;}public String getEmpPwd() {return empPwd;}public void setEmpPwd(String empPwd) {this.empPwd = empPwd;}}然后在hibernate中增加加载该实体类：第一种方式（注解方式）第二种方式，给实体类增加Employee.hbm.xml文件,然后配置xml方式也可七、建立EmployeeDao，这里为简化，方便看的一种package com.scce.dao;import org.hibernate.Session;importorg.springframework.orm.hibernate3.support.HibernateDaoSupport; import java.util.*;public class EmployeeDao extends HibernateDaoSupport {// 登录判断public boolean checkLogin(String empName, String empPwd) { String hql = "from Employee where empName = '" + empName + "' and empPwd='" + empPwd + "'";List lst = this.getHibernateTemplate().find(hql);if (lst.size() > 0) {return true;}return false;}}在spring中配置DAO，注入SessionFactory将sessionFactory注入到dao中----------------------------特别注意，因为上面使用了注解实体类，所以sessionFactory的bean 必须更改为AnnotationSessionFactoryBean<bean id="sessionFactory"class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFac toryBean"><property name="configLocation"value="classpath:hibernate.cfg.xml"></property></bean>-------------------------------------------如果是合并的方式，请注意看以下配置：<bean id="dataSource" class="mons.dbcp.BasicDataSource"><property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property><property name="url" value="jdbc:oracle:thin:@localhost:1521:scce"></property><property name="username" value="scott"></property><property name="password" value="scce"></property></bean><bean id="sessionFactory"class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource"><ref bean="dataSource" /></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</prop><prop key="hibernate.show_sql">true</prop></props></property><property name="packagesToScan"><list><value>com.scce.bean</value></list></property></bean><bean id="eBookDAO" class="com.scce.dao.EBookDAO"> <property name="sessionFactory"><ref bean="sessionFactory" /></property><property name="poName"><value>com.scce.bean.SystemUser</value></property></bean><bean id="usersDAO" class="ersDAO"> <property name="sessionFactory"><ref bean="sessionFactory" /></property><property name="poName"><value>ers</value></property></bean><bean id="booksDAO" class="com.scce.dao.BooksDAO"> <property name="sessionFactory"><ref bean="sessionFactory" /></property><property name="poName"><value>com.scce.bean.Books</value></property></bean><bean id="orderDAO" class="com.scce.dao.OrderDAO"> <property name="sessionFactory"><ref bean="sessionFactory" /></property><property name="poName"><value>com.scce.bean.Order_Form</value> </property></bean><bean id="subOrderDAO" class="com.scce.dao.SubOrderDAO"> <property name="sessionFactory"><ref bean="sessionFactory" /></property><property name="poName"><value>com.scce.bean.SubOrder</value></property></bean><bean id="sshHandler" class="com.scce.service.SSHHandlerImpl"><property name="eBookDAO"><ref bean="eBookDAO"></ref></property><property name="usersDAO"><ref bean="usersDAO"></ref></property><property name="booksDAO"><ref bean="booksDAO"></ref></property><property name="orderDAO"><ref bean="orderDAO"></ref></property><property name="subOrderDAO"><ref bean="subOrderDAO"></ref></property></bean></beans>八、建立struts的action控制器类，这里叫EmployeeActionpackage com.scce.action;import com.scce.bean.Employee;import com.scce.dao.EmployeeDao;public class EmployeeAction {private Employee emp = new Employee();//封装数据用public Employee getEmp() {return emp;}public void setEmp(Employee emp) {this.emp = emp;}// DAOprivate EmployeeDao empDao;//访问数据库的Dao对象，spring注入// 提供对外的set方法，让spring注入进来public void setEmpDao(EmployeeDao empDao) {this.empDao = empDao;}//登录方法public String checkLogin() {boolean isLogin = this.empDao.checkLogin(emp.getEmpName(), emp.getEmpPwd());if (isLogin) {return"login_yes";}return"login_no";}}在spring和strut配置文件中配置Action的存在Struts中：九、页面中：要点：1、action中的写法注意2、文本框name的名字，为什么要加emp.，主要是和action中的对象属性对应，当然如果Action中是字符串属性，则这里可以直接对应即可总结：上面的小例子是SSH的一个步骤，不是很好，但基本流程是这样。
