dubbo+zookeeper+jsp+springmvc+spring+mybatis+…

新老客户大回馈,云服务器低至5折

项目分为三部分，这里分为三个maven项目(基于web，所以最后一个为maven创建的web项目)

1.接口定义以及实体类定义（api+pojo） --- maven创建java项目，打包成jar

2.dubbo的服务提供方：定义接口实现，底层使用mybatis持久层框架，mysql数据库 在这里配置mapper文件以及dubbo-provider的配置文件，还有spring和mybatis整合的文件 ---maven创建java项目，打包成jar

3.dubbo的服务消费方：定义controller类，Jsp页面，配置springmvc的配置文件，web.xml文件，dubbo-consumer的配置文件 ---maven创建的web项目，打包成war包

4.zookeeper：dubbo的注册中心（自己下载 ，找到bin目录下的zkServer.cmd双击打开 ）找不到下载地址的可以从我的github上面下载 ，这是我的整个项目链接，第四个zookeeper.zip就是zookeeper的包 需要项目源码的也可以直接下载  https://github.com/DFX339/dubbo_zookeeper_SSM.git

（1）**********************************数据库（MYSQL）***************************************

创建数据库dubbo ：  create dababase dubbo

在dubbo数据库中创建user表,字段如下：

到这里了就可以下载zookeeper，然后打开文件夹，进入bin目录，双击zkServer.cmd 启动 （让它一直处于启动状态，可以放置一边了）

先将接口项目 demo-interface打包成jar包(打包方式：Eclipse工具 右击项目 maven install)

再将服务提供方项目 demo_provider打包为jar包（打包方式：Eclipse工具 右击项目 maven install)

 

找到demo_provider项目的Provider.java，以Java Applicaion的方式执行 执行结果如下

看到这里，说明前面的配置都没问题

配置结束，接下来就是部署项目到Tomcat上了

 

先将项目打包为war,  Eclipse开发工具 右击项目 run as  --> maven install

运行项目： 右击项目--》run as -->Run on Server (执行成功的前提： zkServer.cmd处于打开状态，Provider.java处于运行状态，demo_interface,demo_provider两个项目都已经使用maven命令打包为jar)

运行项目的结果

 

点击超链接 查询 的结果（其余增加、修改、删除都是一样 ）
