【學習筆記】服務治理工具Dubbo的配置整理
阿新 • • 發佈：2019-07-08
dubbo的結構可分為：服務生產者Provider、服務執行容器Container、服務消費者Consumer、註冊中心Register、監控中心Monitor
作用是，暴露介面，提供服務，其他工廠需要依賴這個介面，像呼叫本地API一樣呼叫遠端API。可以提高程式碼的複用。
公共介面（打包為jar）：
package cn.xing.service;
public interface UserService {
void findUser(int id);
}
服務提供者：
package cn.xing.service.Impl; import org.springframework.stereotype.Service; import cn.xing.service.UserService; @Service public class UserServiceImpl implements UserService{ @Override public void findUser(int id) { // TODO Auto-generated method stub System.out.println("服務提供者：服務被呼叫了。。。。"); } }

服務消費者：
package cn.xing.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import cn.xing.service.UserService; @Controller public class controller { @Autowired private UserService us; @RequestMapping("/dubbo") public String test() { us.findUser(1); return "ok"; } @RequestMapping("/{page}") public String show(@PathVariable String page) { return page; } }
