ssh;struts+spring+hibernate

通过一个项目来实现ssh整合:

1.导包:spring基本包,springsource下的包 struts2基本包,struts2与spring插件包 hibernate基本的包:

d

2.书写配置文件:

web.xml文件

数据库连接配置文件:db.properties

struts.xml:用于配置action

applicationContex.xml:用于配置所有的

web,xml文件:配置spring监听器,读取,spring的配置文件 扩大session的作用域,配置struts2拦截器

<!-- 让Spring随web容器启动而创建监听器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <!--配置session的作用域 
 	注意 openSessionInView一定要在struts中的filter的之前
 -->
 <filter>
      <filter-name>openSessionInView</filter-name>
      <filter-class>
        org.springframework.orm.hibernate5.support.OpenSessionInViewFilter
      </filter-class>
   </filter>
   <filter-mapping>
      <filter-name>openSessionInView</filter-name>
      <url-pattern>/*</url-pattern>
   </filter-mapping>
 <!-- 配置struts拦截器 -->
 <filter>
      <filter-name>struts2</filter-name>
      <filter-class>
         org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
      </filter-class>
   </filter>
   <filter-mapping>
      <filter-name>struts2</filter-name>
      <url-pattern>/*</url-pattern>
   </filter-mapping>

struts.xml:用于配置action的操作配置拦截器,注意:
           <!-- 配置常量意思是否把action对象交给Spring容器来管理和创建 -->
        <constant name="struts.objectFactory" value="spring"></constant>
        <!-- 用来配置Action的的依赖注入属性 -->
        <constant name="struts.objectFactory.spring.autoWire" value="name"></constant>

这里的action所对应的class为appliationcontext.xml实例action时对应的id属性.在struts2高版本中需要用<allowed-method>标签来制定允许的action中的响应的方法

<struts>
 <!-- developerment Mode:开发模式以后修改下面配置,不需要重新启动Tmocat服务器 -->
    <constant name="struts.devMode" value="true" />
		<!-- 配置常量意思是否把action对象交给Spring容器来管理和创建 -->
		<constant name="struts.objectFactory" value="spring"></constant>
		<!-- 用来配置Action的的依赖注入属性 -->
		<constant name="struts.objectFactory.spring.autoWire" value="name"></constant>
		<!-- 允许动作名称有斜杠 -->
		<constant name="struts.enable.SlashesInActionNames " value="true"></constant>
		<!-- user -->
		<package name="user" namespace="/" extends="struts-default">
				<interceptors>
				<!-- 注册拦截器 -->
						<interceptor name="privilegeInterceptor" class="com.leo.crm.interceptor.PrivilegeInterceptor"></interceptor>
						
				<!-- 配置拦截器栈 -->
						<interceptor-stack name="myStack">
							<interceptor-ref name="privilegeInterceptor">
								<param name="excludeMethods">login,regist</param>
							</interceptor-ref>
							<interceptor-ref name="defaultStack"></interceptor-ref>
						</interceptor-stack>
					</interceptors>
				<!-- 指定默认拦截器栈 -->
				<default-interceptor-ref name="myStack"></default-interceptor-ref>
				
				<!-- 全局结果集配置 -->
				<global-results>
					<result name="toLogin" type="redirect" >/login.jsp</result>
				</global-results>
				<global-exception-mappings>
					<exception-mapping result="error" exception="java.lang.RuntimeException"></exception-mapping>
				</global-exception-mappings>
			<!--方案二:	class属性填写Spring中action对象的beanName,就是spring管理的xml中配置的bean的名字。完全有Spring来创建管理action的周期
							注意;Spring不能自动组装,只能手动注入依赖属性 -->
			<!-- 关键地方  struts2.5 为了提升安全性,添加了 allomethod 这个属性			
			<global-allowed-methods>regex:.*</global-allowed-methods>-->
			<action name="userAction_*" class="userAction" method="{ 1 }">
				<result name="toHome" type="redirect">/index.htm</result>
				<result name="error">/login.jsp</result>
				<allowed-methods>login</allowed-methods>
			</action>
			<action name="userAction_login" class="userAction" method="login">
				 <result name="toHome"  type="redirect">index.htm</result>
				 <result name="error">/login.jsp</result>
			</action>
		</package>

在applicationConte.xml需要做以下配置:

1.引入数据源配置文件,2.引入hibernate的映射文件3.注入sesssionfactory,4.实例化其他的各个层

hibernate映射文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.leo.crm.domain">
	<class name="User" table="crm_user">
		<id name="user_id" column="user_id">
			<generator class="native"></generator>
		</id>
		<property name="user_code" column="user_code"></property>
		<property name="user_name" column="user_name"></property>
		<property name="user_password" column="user_password"></property>
		<property name="user_state" column="user_state"></property>
	</class>

</hibernate-mapping>

这时只需要在dao层进行继承HibernateDaoSupport就可以了,其他层不变:

比如一个抽取出来的操作数据的类:

/**
 * 实现BaseDao接口
 * @author leoi555
 *
 */
public class BaseDaoImpl<T> extends HibernateDaoSupport implements BaseDao<T>{
	private Class clazz;//接收运行期的泛型类型
	public BaseDaoImpl() {
		// TODO Auto-generated constructor stub
		//获得当前类型的父类(父类中含有泛型)
		ParameterizedType genericSuperclass = (ParameterizedType) this.getClass().getGenericSuperclass();
		//获得运行期的泛型类型
		//返回值为数组类型的,最后再取出
		clazz = (Class) genericSuperclass.getActualTypeArguments()[0];
	}
	@Override
	public void save(T t) {
		// TODO Auto-generated method stub
		getHibernateTemplate().save(t);
	}
	
	@Override
	public void delete(T t) {
		// TODO Auto-generated method stub
		getHibernateTemplate().delete(t);
	}

	@Override
	public void delete(Serializable id) {
		// TODO Auto-generated method stub
		//先取出这个
		T byId = this.getById(id);
		getHibernateTemplate().delete(byId);
	}

	@Override
	public void update(T t) {
		// TODO Auto-generated method stub
		getHibernateTemplate().update(t);
	}

	@Override
	public T getById(Serializable id) {
		// TODO Auto-generated method stub
		return (T) getHibernateTemplate().get(clazz, id);
		
	}

	@Override
	public Integer getTotalCount(DetachedCriteria dc) {
		// TODO Auto-generated method stub
		//需要用聚合函数
				dc.setProjection(Projections.rowCount());
				List list = getHibernateTemplate().findByCriteria(dc);
				//清空聚合函数
				dc.setProjection(null);
				if (list!=null && list.size()>0) {
					Long count=(Long) list.get(0);
					return count.intValue();//这是返回int性的
				}else {
					return null;
				}
		
	}

	@Override
	public List<T> getPageList(DetachedCriteria dc, Integer start, Integer pageSize) {
		// TODO Auto-generated method stub
		List<T> list=(List<T>) this.getHibernateTemplate().findByCriteria(dc, start, pageSize);
		return list;
	}
	@Override
	public void saveOrUpdate(T t) {
		// TODO Auto-generated method stub
		this.getHibernateTemplate().saveOrUpdate(t);
	}

	

}

domain层中书写映射文件,书写pojo同时属性要和数据裤字段一致,web层就是写的action,这里的所有的属性都生成setget方法由spring容器进行管理然后进行实例化

/**
 * 操作user的Action
 * @author leoi555
 *
 */
public class CustomerAction extends ActionSupport implements ModelDriven<Customer>{
	private Customer customer;
	private CustomerService customerService;
	private Integer currentPage;
	private Integer pageSize;
	//后台提供name与属性相同的就可以
	private File photo;//接收文件
	private String photoContentType;//file类型mime类型
	private String photoFileName;//file 名称

	public String getPhotoContentType() {
		return photoContentType;
	}
	public void setPhotoContentType(String photoContentType) {
		this.photoContentType = photoContentType;
	}
	public String getPhotoFileName() {
		return photoFileName;
	}
	public void setPhotoFileName(String photoFileName) {
		this.photoFileName = photoFileName;
	}
	public File getPhoto() {
		return photo;
	}
	public void setPhoto(File photo) {
		this.photo = photo;
	}
	public Integer getCurrentPage() {
		return currentPage;
	}
	public void setCurrentPage(Integer currentPage) {
		this.currentPage = currentPage;
	}
	public Integer getPageSize() {
		return pageSize;
	}
	public void setPageSize(Integer pageSize) {
		this.pageSize = pageSize;
	}
	public CustomerService getCustomerService() {
		return customerService;
	}
	public void setCustomerService(CustomerService customerService) {
		this.customerService = customerService;
	}
	@Override
	public Customer getModel() {
		// TODO Auto-generated method stub
		return customer;
	}
	public Customer getCustomer() {
		return customer;
	}
	public void setCustomer(Customer customer) {
		this.customer = customer;
	}
	/**
	 * 获得列表
	 * @return
	 */
	public String list() {
		//封装离线查询对象
		DetachedCriteria  dCriteria=DetachedCriteria.forClass(Customer.class);
		if (org.apache.commons.lang3.StringUtils.isNotBlank(customer.getCust_name())) {
			dCriteria.add(Restrictions.like("cust_name", "%"+customer.getCust_name()+"%"));
		}
		PageBean bean=customerService.getPageBean(dCriteria,currentPage,pageSize);
		ActionContext.getContext().put("PageBean", bean);
		return "list";
	}
	/**
	 * 保存客户
	 * @param customer
	 * @return
	 */
	public String  saveCustomer(){
		if (photo!=null) {
			System.out.println("文件名称:"+photoFileName);
			System.out.println("文件类型:"+photoContentType);
			//将文件保存到指定的位置
			photo.renameTo(new File("/upload/photo.jpg"));
		}
		customerService.addCustomer(customer);
		return "toList";
	}
	/**
	 * 获取指定的用户
	 * @param id
	 * @return
	 */
	public String  getCutomerById() {
		Customer customer =customerService.getCustomerById(this.customer.getCust_id());
		System.out.println(customer.getCust_id()+customer.getCust_linkman());
		System.out.println(customer);
		//将客户放到request域
		ActionContext.getContext().put("customer", customer);
		return "edit";
	}
	public String deleteCustomer() {
		customerService.deleteCustomer(customer.getCust_id());
		return "toList";
	}
}

其他各层的逻辑该怎么写还是怎么写,其他各层不变
