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">
<!-- 业务类 -->
<bean id="customerService" class="cn.rodge.crm.service.impl.CustomerServiceImpl" />
<!-- 注册hessian服务 -->
<bean id="/customer" class="org.springframework.remoting.caucho.HessianServiceExporter">
<!-- 业务接口实现类 -->
<property name="service" ref="customerService" />
<!-- 业务接口 -->
<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.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);
}
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
<bean id="customerService" class="org.springframework.remoting.caucho.HessianProxyFactoryBean">
<property name="serviceInterface" value="cn.rodge.crm.service.CustomerService"></property>
<property name="serviceUrl" value="http://localhost:8080/crm/remoting/customer"></property>
</bean>
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;
