[原]Java web学习系列之 Java web开发中的SSH整合(Struts、Spring、Hibernate)(下)

接上一篇：

创建dao接口类及方法：

public interface UsersDAO {
public void save(Users user);
public void delete(Users user);
public void update(Users user);
public void findById(String name);
}

创建dao类方法的实现类：

public class UsersDAOImpl extends HibernateDaoSupport implements UsersDAO{

public void delete(Users user) {
// TODO Auto-generated method stub

}

public void findById(String name) {
// TODO Auto-generated method stub

}

public void save(Users user) {
// TODO Auto-generated method stub

}

public void update(Users user) {
// TODO Auto-generated method stub
}
}

创建service接口类：

public interface UsersService {
    public void deleteUsers(String name,String pwd);
    public Users findUsers(String name,String pwd);
    public void delete_find(String name,String pwd);
}
创建service接口类的实现类：

public class UsersServiceImpl implements UsersService {
//注入对象
private UsersDAO usersDAO=null;

public UsersDAO getUsersDAO() {
return usersDAO;
}

public void setUsersDAO(UsersDAO usersDAO) {
this.usersDAO = usersDAO;
}

public void deleteUsers(Users user) {
usersDAO.delete(user);
}

public void deleteUsers(String name, String pwd) {
// TODO Auto-generated method stub
}

public void delete_find(String name, String pwd) {
Users users=this.findUsers(name, pwd);
this.deleteUsers(users);
}

public Users findUsers(String name, String pwd) {
  // TODO Auto-generated method stub
  return null;
}

}

添加action：

public class LoginAction extends Action {
private UsersService usersService=null;
public ActionForward execute(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
  LoginForm loginForm = (LoginForm) form;// TODO Auto-generated method stub
  //判断注入是否成功
  //System.out.println(usersService);
  Users users=loginForm.getUsers();
  usersService.delete_find(users.getUserName(), users.getPassword());

  return mapping.findForward("index");
}

public UsersService getUsersService() {
  return usersService;
}

public void setUsersService(UsersService usersService) {
this.usersService = usersService;
}

}

LoginForm 中方法的构造：

public class LoginForm extends ActionForm {

private Users users=new Users();

public Users getUsers() {
return users;
}

public void setUsers(Users users) {
this.users = users;
}

public ActionErrors validate(ActionMapping mapping,
   HttpServletRequest request) {
  // TODO Auto-generated method stub
  return null;
}

public void reset(ActionMapping mapping, HttpServletRequest request) {
// TODO Auto-generated method stub
}
}

<struts-config>
<form-beans >
<form-bean name="loginForm" type="org.clarck.struts.form.LoginForm" />

</form-beans>

<global-exceptions />
<global-forwards />
<action-mappings >
    <action
      attribute="loginForm"
      input="/login.jsp"
      name="loginForm"
      path="/login"
      scope="request"
      type="org.clarck.struts.action.LoginAction">
      <forward name="index" path="/index.jsp" />
    </action>
</action-mappings>

在Struts—config.xml中配置文件：

<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"/>
//转交控制权的配置文件必须在<message-resources />之上

<message-resources parameter="org.clarck.struts.ApplicationResources" />
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="classpath:applicationContext.xml"/>
</plug-in>

</struts-config>

在applicationContext.xml中配置Javabean：

新建dao.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

<bean id="usersService" class="org.clarck.model.service.impl.UsersServiceImpl">
     <property name="usersDAO" ref="usersDAO"/>
   </bean>
</beans>

配置service.xml：

<bean name="/login" class="org.clarck.struts.action.LoginAction">
     <property name="usersService" ref="usersService"/>
   </bean>
</beans>

配置action.xml：

<bean name="/login" class="org.clarck.struts.action.LoginAction">
     <property name="usersService" ref="usersService"/>
   </bean>
</beans>

在applicationContext.xml中导入配置好的xml文件：

在applicationContext.xml中配置事务管理器：

<bean id="transactionmanager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager" >
<property name="sessionFactory" ref="sessionFactory" />
</bean>

在applicationContext.xml中配置事务管理策略：

<tx:advice id="txAdvice" transaction-manager="transactionmanager">
  <tx:attributes>
   <tx:method name="save*" propagation="REQUIRED" />
   <tx:method name="delete*" propagation="REQUIRED" />
   <tx:method name="update*" propagation="REQUIRED" />
   <tx:method name="login" propagation="REQUIRED" />
   <tx:method name="find*" propagation="SUPPORTS"
    read-only="true" />
   <tx:method name="*" propagation="SUPPORTS" read-only="true" />
  </tx:attributes>
</tx:advice>

在applicationContext.xml中配置事物拦截切：

<aop:config>
  
  <aop:pointcut id="allBiz" expression="execution(* org.clarck.model.service.impl.*.*(..))"/>
  <aop:advisor pointcut-ref="allBiz" advice-ref="txAdvice"/>
</aop:config>

在applicationContext.xml中配置配置日志对象的切点：

<bean id="log" class="org.clarck.model.interceptor.Log" />

在applicationContext.xml中配置配置日志拦截切面：

<aop:config>
  <aop:aspect ref="log">
   <aop:before pointcut-ref="allBiz" method="before"/>
  </aop:aspect>
</aop:config>

配置日志文件类：

public class Log {
     public void before(JoinPoint point){
    System.out.println("你调用了"+point.getSignature().getName()+"方法");
       }
}
