使用Spring Boot 与Dubbo集成.这里使用的是XML而不是注解
代码地址：https://github.com/csy512889371/learndemo/tree/master/ctoedu-springboot-dubbo
- ctoedu-springboot-dubbo-consumer 消费端
- ctoedu-springboot-dubbo-provider 提供端

@Autowired
ComputeService computeService;
@Test
public void testAdd() throws Exception {
System.out.println("cn.ctoedu: Dubbo消费结果为：。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。"+computeService.add(100, 200));
Assert.assertEquals("compute-service:add", new Integer(3), computeService.add(1, 2));
//Assert.assertEquals("compute-service:add", new Integer(5), computeService.add(1, 2));
}
