分布式项目搭建
今天学习分布式的项目搭建,第二天使用 intelliJ IDEA 渐渐适应了操作
搭建分布式项目,我把他分为一个父工程和14个子工程
如图是各项目的关系依赖:
idea包结构:
搭建好我们所需要的工程之后,我们就需要配置XML文件和POM.xml文件
父工程的POM文件

这里<dependencyManagement>指的是锁定版本号 真正实现依赖的是common pom.xml文件里的<dependencies>
package com.ujiuye.service; import com.ujiuye.pojo.good.Brand; import java.util.List; public interface BrandService { public List<Brand> findAll(); }
在service中实现这个接口
package com.ujiuye.service; import com.alibaba.dubbo.config.annotation.Service; import com.ujiuye.dao.good.BrandDao; import com.ujiuye.pojo.good.Brand; import org.springframework.beans.factory.annotation.Autowired; import java.util.List; @Service public class BrandServiceImpl implements BrandService{ @Autowired private BrandDao brandDao; @Override public List<Brand> findAll() { List<Brand> brands = brandDao.selectByExample(null); return brands; } }
controller层
package com.ujiuye.controller; import com.alibaba.dubbo.config.annotation.Reference; import com.ujiuye.pojo.good.Brand; import com.ujiuye.service.BrandService; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import java.util.List; @RestController @RequestMapping("/Brand") public class BrandController { @Reference private BrandService brandService; @RequestMapping("/findAll") public List<Brand> findAll(){ List<Brand> list = brandService.findAll(); return list; } }
部署tomcat 先启动service层后启动controller 注意端口号不要重复
启动zookeeper,接下来我们就可以测试我们的代码了!
在url栏输入我们的地址
可以看到 我们成功实现了利用分布式实现了查询数据库中的商品表,因为没有相关的页面 返回的是一个json格式的数据
