hessian在ssh项目中的配置

一. 在服务端发布一个web项目

1.创建一个动态的web项目,并导入hessian的jar包

2. 在服务端的crm项目中创建接口

package cn.rodge.crm.service;
import java.util.List;
import cn.rodge.crm.domain.Customer;
// 客户服务接口
public interface CustomerService {
   // 未关联定区客户
   public List<Customer> findnoassociationCustomers();
   // 查询已经关联指定定区的客户
   public List<Customer> findhasassociationCustomers(String decidedZoneId);
   // 将未关联定区客户关联到定区上
   public void assignCustomersToDecidedZone(Integer[] customerIds, String decidedZoneId);
   // 根据电话查询客户
   public List<Customer> findCustomerByTelephone (String telephone);
   //根据地址查询定区id
   public String findDecidedZoneByAddress (String address);
}

Customer.java实体类
package cn.rodge.crm.domain;
import java.io.Serializable;
public class Customer implements Serializable {
   private Integer id;
   private String name;
   private String station;
   private String telephone;
   private String address;
   private String decidedzone_id;
   public Integer getId() {
       return id;
   }
   public void setId(Integer id) {
       this.id = id;
   }
   public String getName() {
       return name;
   }
   public void setName(String name) {
       this.name = name;
   }
   public String getStation() {
       return station;
   }
   public void setStation(String station) {
       this.station = station;
   }
   public String getTelephone() {
       return telephone;
   }
   public void setTelephone(String telephone) {
       this.telephone = telephone;
   }
   public String getAddress() {
       return address;
   }
   public void setAddress(String address) {
       this.address = address;
   }
   public String getDecidedzone_id() {
       return decidedzone_id;
   }
   public void setDecidedzone_id(String decidedzone_id) {
       this.decidedzone_id = decidedzone_id;
   }
}

Customer.hbm.xml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>
   <class name="cn.rodge.crm.domain.Customer" table="t_customer">
       <id name="id">
           <generator class="native"></generator>
       </id>
       <property name="name"></property>
       <property name="station"></property>
       <property name="telephone"></property>
       <property name="address"></property>
       <property name="decidedzone_id"></property>
   </class>
</hibernate-mapping>

3.针对接口提供实现类

package cn.rodge.crm.service.impl;
import java.util.List;
import org.hibernate.Session;
import cn.rodge.crm.domain.Customer;
import cn.rodge.crm.service.CustomerService;
import cn.rodge.crm.utils.HibernateUtils;
public class CustomerServiceImpl implements CustomerService {
   public List<Customer> findnoassociationCustomers() {
       Session session = HibernateUtils.openSession();
       session.beginTransaction();
       String hql = "from Customer where decidedzone_id is null";
       List<Customer> customers = session.createQuery(hql).list();
       session.getTransaction().commit();
       session.close();
       return customers;
   }
   public List<Customer> findhasassociationCustomers(String decidedZoneId) {
       Session session = HibernateUtils.openSession();
       session.beginTransaction();
       String hql = "from Customer where decidedzone_id = ?";
       List<Customer> customers = session.createQuery(hql).setParameter(0, decidedZoneId).list();
       session.getTransaction().commit();
       session.close();
       return customers;
   }
   public void assignCustomersToDecidedZone(Integer[] customerIds, String decidedZoneId) {
       Session session = HibernateUtils.openSession();
       session.beginTransaction();
       // 取消定区所有关联客户
       String hql2 = "update Customer set decidedzone_id=null where decidedzone_id=?";
       session.createQuery(hql2).setParameter(0, decidedZoneId).executeUpdate();
       // 进行关联
       String hql = "update Customer set decidedzone_id=? where id =?";
       if (customerIds != null) {
           for (Integer id : customerIds) {
               session.createQuery(hql).setParameter(0, decidedZoneId).setParameter(1, id).executeUpdate();
           }
       }
       session.getTransaction().commit();
       session.close();
   }
   public List<Customer> findCustomerByTelephone(String telephone) {
       Session session = HibernateUtils.openSession();
       session.beginTransaction();
       String hql = "from Customer where telephone = ?";
       List<Customer> customers = session.createQuery(hql).setParameter(0, telephone).list();
       session.getTransaction().commit();
       session.close();
       return customers;
   }
   public String findDecidedZoneByAddress(String address) {
       Session session = HibernateUtils.openSession();
       session.beginTransaction();
       String hql = "select decidedzone_id from Customer where address = ?";
       List<String> list = session.createQuery(hql).setParameter(0, address).list();
       String decidedzone_id = null;
       if (list != null && list.size() > 0) {
           decidedzone_id = list.get(0);
       }
       session.getTransaction().commit();
       session.close();

       return decidedzone_id;
   }
}

4.在web.xml中配置spring框架的一个Servlet

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
   xmlns="http://java.sun.com/xml/ns/javaee"
   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">
<display-name></display-name>
<servlet>
   <servlet-name>remoting</servlet-name>
   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
   <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
   <servlet-name>remoting</servlet-name>
   <url-pattern>/remoting/*</url-pattern>
</servlet-mapping>

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

5.在WEB-INF目录下提供配置文件remoting-servlet.xml，注册服务

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xmlns:aop="http://www.springframework.org/schema/aop"
   xmlns:tx="http://www.springframework.org/schema/tx"
   xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context.xsd
   http://www.springframework.org/schema/aop
   http://www.springframework.org/schema/aop/spring-aop.xsd
   http://www.springframework.org/schema/tx
   http://www.springframework.org/schema/tx/spring-tx.xsd">
   
   <bean id="customerService" class="cn.rodge.crm.service.impl.CustomerServiceImpl" />

   
   <bean id="/customer" class="org.springframework.remoting.caucho.HessianServiceExporter">
       
       <property name="service" ref="customerService" />
       
       <property name="serviceInterface" value="cn.rodge.crm.service.CustomerService" />
   </bean>
</beans>

二. 在客户端

1. 导入hessian的jar包

2. 在项目同提供一个接口, 与服务端中提供的接口一致. 如果服务单有向客户端传递自定义类, 则也需要在客户端进行相应的配置

package cn.rodge.crm.domain;
import java.io.Serializable;
public class Customer implements Serializable {
   private Integer id;
   private String name;
   private String station;
   private String telephone;
   private String address;
   private String decidedzone_id;
   public Integer getId() {
       return id;
   }
   public void setId(Integer id) {
       this.id = id;
   }
   public String getName() {
       return name;
   }
   public void setName(String name) {
       this.name = name;
   }
   public String getStation() {
       return station;
   }
   public void setStation(String station) {
       this.station = station;
   }
   public String getTelephone() {
       return telephone;
   }
   public void setTelephone(String telephone) {
       this.telephone = telephone;
   }
   public String getAddress() {
       return address;
   }
   public void setAddress(String address) {
       this.address = address;
   }
   public String getDecidedzone_id() {
       return decidedzone_id;
   }
   public void setDecidedzone_id(String decidedzone_id) {
       this.decidedzone_id = decidedzone_id;
}

3. 在spring的applicationContext.xml中配置一个代理对象

4.通过注解, 将这个代理对象注入给相应的类

　　//注入hessian中的customerService
@Resource
private CustomerService customerService;
