Dubbo+zookeeper应用的入门案例
前提：Linux安装zookeeper Dubbo管理中心部署
简单案例的项目结构：
1，demo_parent的pom.xml，用来统一管理依赖

2，在父工程下新建pojo工程，用来管理pojo实体类
User实体类：
package com.zy.pojo; import java.io.Serializable; import java.util.Date; public class User implements Serializable { private Long id; // 用户名 private String userName; // 密码 private String password; // 姓名 private String name; // 年龄 private Integer age; // 性别，1男性，2女性 private Integer sex; // 出生日期 private Date birthday; // 创建时间 private Date created; // 更新时间 private Date updated; 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; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } public Integer getSex() { return sex; } public void setSex(Integer sex) { this.sex = sex; } public Date getBirthday() { return birthday; } public void setBirthday(Date birthday) { this.birthday = birthday; } public Date getCreated() { return created; } public void setCreated(Date created) { this.created = created; } public Date getUpdated() { return updated; } public void setUpdated(Date updated) { this.updated = updated; } @Override public String toString() { return "User [id=" + id + ", userName=" + userName + ", password=" + password + ", name=" + name + ", age=" + age + ", sex=" + sex + ", birthday=" + birthday + ", created=" + created + ", updated=" + updated + "]"; } }
3，在父工程下新建dao工程
pom.xml

UserMapper接口
package com.zy.mapper; import com.zy.pojo.User; import java.util.List; public interface UserMapper { List<User> getUserList(); }
对应的UserMapper.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.zy.mapper.UserMapper"> <!--写sql--> <select id="getUserList" resultType="com.zy.pojo.User"> select * from tb_user </select> </mapper>

UserService接口
package com.zy.service; import com.zy.pojo.User; import java.util.List; //接口 public interface UserService { /** * 查询所有User信息 */ public List<User> getUserList(); }
5，在父工程下新建service项目（war工程），管理业务层接口实现类

UserServiceImpl接口实现类
package com.zy.service.impl; import com.alibaba.dubbo.config.annotation.Service; import com.zy.mapper.UserMapper; import com.zy.pojo.User; import com.zy.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import java.util.List; @Service //这里的注解是com.alibaba.dubbo.config.annotation.Service的 public class UserServiceImpl implements UserService { @Autowired private UserMapper userMapper; @Override public List<User> getUserList() { return userMapper.getUserList(); } }
业务实现层spring配置文件applicationContext-service.xml

7，安装项目
8，启动service和web的tomcat，访问dubbo管理中心
9，访问我们项目中写好的controller中的方法
