说明：这里只简单演示使用dubbo远程调用框架实现接口调用，zookeeper安装到本地测试
项目说明：
com.maven.api：公用api，这里只存放最基本的service接口，以及实体类，pom.xml中需要引入dubbo+zookeeper 依赖包
com.maven.core：服务提供方，也是数据库访问层，实现业务逻辑，需要引入com.maven.api依赖
com.maven.consumer：服务调用方，web项目，对外开放访问权限，需要引入com.maven.api依赖
一，com.maven.api 项目
(一) 引入依赖包，pom.xml 配置文件如下：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.maven.dubbo</groupId>

<version>0.0.1-SNAPSHOT</version>
<dependencies>
<dependency>

</dependency>
<dependency>
<groupId>com.101tec</groupId>
<artifactId>zkclient</artifactId>
<version>0.7</version>
</dependency>
</dependencies>
</project>(二) 新建UserService
package com.maven.facade;
import java.util.List;
import com.maven.entity.UserInfo;
public interface UserService {
Integer insert(UserInfo userInfo);
Integer delete(Long uid);
UserInfo select(Long uid);
/** 获取用户信息集合 */
List<UserInfo> listUserInfo();
}
package com.maven.entity;
import java.io.Serializable;
import java.util.Date;
public class UserInfo implements Serializable{
private static final long serialVersionUID = 5775086719909153531L;
private Long id;
private String userName;
private String password;
private String email;
private String phone;
private String sex;
private String status;
private Date createTime;
private Date updateTime;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName == null ? null : userName.trim();
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password == null ? null : password.trim();
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email == null ? null : email.trim();
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone == null ? null : phone.trim();
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex == null ? null : sex.trim();
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status == null ? null : status.trim();
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
public Date getUpdateTime() {
return updateTime;
}
public void setUpdateTime(Date updateTime) {
this.updateTime = updateTime;
}
@Override
public String toString() {
return "UserInfo [id=" + id + ", userName=" + userName + ", password=" + password + ", email=" + email
+ ", phone=" + phone + ", sex=" + sex + "]";
}
}使用sping+mybatis+mysql构建项目，前面已经介绍过相关框架，这里不多介绍

<import resource="classpath:Spring-dubbo.xml" />
</beans>(三) 配置Spring-dubbo.xml，配置注册中心地址，暴露dubbo服务
这里使用的是安装在本地的zookeeper，启动项目前需要先启动zookeeper，默认端口2181
<?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:dubbo="http://code.alibabatech.com/schema/dubbo"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://code.alibabatech.com/schema/dubbo
http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
<!-- 提供方应用信息，用于计算依赖关系 -->
<dubbo:application name="dubbo_provider" organization="com_maven_dubbo" />
<!-- 使用zookeeper注册中心暴露服务地址 -->
<dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" />
<!-- 用dubbo协议在20880端口暴露服务 -->
<dubbo:protocol name="dubbo" port="20880" />
<import resource="classpath:dubbo-provider.xml" />
</beans>(四) 配置dubbo-provider.xml，这里主要是配置需要提供服务的接口及方法
<?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:dubbo="http://code.alibabatech.com/schema/dubbo"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://code.alibabatech.com/schema/dubbo
http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
<!-- 声明需要暴露的服务接口 -->
<dubbo:service interface="com.maven.facade.UserService" ref="userService" >
<dubbo:method name="insert" timeout="10000" retries="0" />
<dubbo:method name="delete" timeout="10000" retries="0" />
<dubbo:method name="select" timeout="10000" retries="0" />
<dubbo:method name="listUserInfo" timeout="100000" retries="0" />
</dubbo:service>
</beans>
本例采用注解方式配置，如下配置@Service("userService")
(五) 新建UserServiceImpl实现UserService接口
package com.maven.core.facade.impl;

@Resource

public Integer insert(UserInfo userInfo) {
return userInfoMapper.insertSelective(userInfo);
}
public Integer delete(Long uid) {
return userInfoMapper.deleteByPrimaryKey(uid);
}
public UserInfo select(Long uid) {
System.out.println("............");
return userInfoMapper.selectByPrimaryKey(uid);
}
public List<UserInfo> listUserInfo() {
System.out.println(".............");
List<UserInfo> list = userInfoMapper.selectAll();
return list;
}
}
package com.maven.core.mapper;
import java.util.List;
import org.springframework.stereotype.Repository;
import com.maven.entity.UserInfo;
@Repository
public interface UserInfoMapper {
int deleteByPrimaryKey(Long id);
int insert(UserInfo record);
int insertSelective(UserInfo record);
UserInfo selectByPrimaryKey(Long id);

List<UserInfo> selectAll();

三，com.maven.consumer

四，项目构建完成，接下来是测试
(一) 启动zookeeper，在本地安装zookeeper后找到bin文件夹，开启zkServer.cmd
(二) 启动服务提供方，找到Provider.java，运行启动
(三) 启动服务调用方，将项目部署到tomcat，启动
(四) 调用测试：
测试成功，分享项目源码：http://pan.baidu.com/s/1jI7J802
