1 # dubbo 与ssm 整的过程
2
3 ## 1、创建一个父工程 贺三个子工程
4
5 父工程 pom
6
7 接口工程 =》jar
8
9 服务提供者=》 jar
10
11 服务消费者=》war
12
13 ## 2、引入依赖

722 ## 编写代码
723
724 ### 编写接口层
725
726 #### 编写实体bean
727
728 注意要点：一定要加序列化。
729
730 #### 编写接口service接口、
731
732 接口中的方法绝对不可以返回空值（void）
733
734
735
736 ### 编写服务层
737
738 #### 实现接口工程中所有的接口。
739
740 实现类上加Service注解，这个service 注解必须是下图中所示的，不能使用spring的。
741
742 
743
744
745
746 #### 编写dao层
747
748 #### 引入配置文件
749

846
847
848
849 #### 编写测试类
850
851 ```java
852 package com.mmcor.pregnant.service.test;
853
854 import org.junit.Test;
855 import org.junit.runner.RunWith;
856 import org.springframework.beans.factory.annotation.Autowired;
857 import org.springframework.test.context.ContextConfiguration;
858 import org.springframework.test.context.junit4.SpringRunner;
859
860 import com.mmcor.pregnant.pojo.User;
861 import com.mmcor.pregnant.service.UserService;
862
863 @RunWith(SpringRunner.class)
864 @ContextConfiguration({"classpath:applicationContext-dao.xml",
865 "classpath:applicationContext-dubbo-provider.xml"})
866 public class TestUser {
867
868
869 @Autowired
870 UserService us;
871
872 @Test
873 public void testLogin() {
874
875 User user = new User();
876 user.setUsername("zhangsan");
877 user.setPassword("123456");
878 User login = us.login(user);
879 System.err.println("等路成功 ? " + (login!=null) );
880
881 }
882
883 }
884
885 ```
886
887
888
889 ### 完成消费者
890
891 #### 编写controller
892
893 小心referenc注解
894
895 ```java
896 package com.mmcor.pregnant.controller;
897
898 import javax.servlet.http.HttpServletRequest;
899
900 import org.apache.dubbo.config.annotation.Reference;
901 import org.springframework.stereotype.Controller;
902
903 import com.mmcor.pregnant.pojo.User;
904 import com.mmcor.pregnant.service.UserService;
905
906 @Controller
907 public class UserController {
908
909 // 特别注意 需要使用apache.dubbo的注解
910 @Reference
911 UserService us;
912
913 public String login(HttpServletRequest request,User user) {
914 User loginUser = us.login(user);
915 if(loginUser==null) {
916 //登录失败 保持在登录的页面
917 return "login";
918 }
919
920 //登录成功
921 request.getSession().setAttribute("sessionuser", user);
922 return "index";
923 }
924
925 }
926
927
928
929
930
931 ```
932
933 #### 完成jsp
