[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：

<!-- 转交控制权给Spring -->
 <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">

    <!-- 该文件只配置Service类 -->
   <bean id="usersService" class="org.clarck.model.service.impl.UsersServiceImpl">
     <property name="usersDAO" ref="usersDAO"/>
   </bean>
</beans>

配置service.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">

    <!-- 该文件只配置Service类 -->
   <bean name="/login" class="org.clarck.struts.action.LoginAction">
     <property name="usersService" ref="usersService"/>
   </bean>
</beans>

配置action.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">

    <!-- 该文件只配置Action类 -->
   <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：

<import resource="dao.xml"/>
 <import resource="service.xml"/>
 <import resource="action.xml"/>

 

在applicationContext.xml中配置事务管理器：

<!-- 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：

<!-- 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>
  <!-- 配置事物拦截切面 -->
  <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：

<!-- 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 ：

   <!-- 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");
       }
}
