实现类的java代码部分(发布、service.impl实现类)
Service实现类:
package com.bjsxt.service.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
//import com.alibaba.dubbo.config.annotation.Service;
import com.bjsxt.mapper.EmpMapper;
import com.bjsxt.pojo.Emp;
import com.bjsxt.service.EmpService;
@Service
public class EmpServiceImpl implements EmpService {
@Autowired
private EmpMapper empMapper;
@Override
public List<Emp> loadEmpListService(Emp emp) {
// TODO Auto-generated method stub
return empMapper.loadEmpListMapper(emp);
}
@Override
public void deleteEmpService(Integer id) {
// TODO Auto-generated method stub
empMapper.deleteEmpMapper(id);
}
}
发布代码:
package com.bjsxt.app;
import java.io.IOException;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class RpcApp {
public static void main(String[] args) {
/****
* 加载spring容器暴露服务
*/
ClassPathXmlApplicationContext
ac=new ClassPathXmlApplicationContext("application-mapper.xml",
"application-service.xml","application-provider.xml");
ac.start();
System.out.println("========暴露服务========");
try {
System.in.read();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
这样就可以把代码发布到dubbo集群中

controller层文件
第一个是用来加载静态代码块配置dubbo的,第二个就是controller层的代码
ConsumerConfig配置文件
package com.bjsxt.controller;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
@Configuration //将静态内部类实例化
//加载dubbo-consumer.properties
@PropertySource("classpath:/dubbo-consumer.properties")
//指定暴露的服务接口对应的包
@EnableDubbo(scanBasePackages = "com.bjsxt.service")
//指定需要扫描Spring组件所在的包
//@ComponentScan(value = {"com.bjsxt.controller"})
public class ConsumerConfig {
public ConsumerConfig() {
System.out.println("=========================");
}
}
EmpController层(注解就用Reference的注解)
package com.bjsxt.controller;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.alibaba.dubbo.config.annotation.Reference;
import com.bjsxt.pojo.Emp;
import com.bjsxt.service.EmpService;
@Controller
public class EmpController {
/*@Autowired
private EmpService empService;
*/@Reference
private EmpService empService;
/***
* 处理员工信息的查询请求
*/
@RequestMapping("/loadEmpList")
public String loadEmpList(Emp emp,Model model) {
List<Emp> result = empService.loadEmpListService(emp);
model.addAttribute("result", result);
return "list";
}
/***
* 处理员工信息删除请求
*/
@RequestMapping("/deleteEmp")
public String deleteEmp(Integer id) {
empService.deleteEmpService(id);
return "redirect:/loadEmpList";
}
}
注解实现文件的发现,与之前注解启动发现服务不同的是需要main方法来加载容器,我们这里把类放在了controller层中,这样spring容器启动会扫描controller层,久会扫描到该类的注解,创建对象读取数据等等一系列的配置
