2, 使用需求
在这里 当我们有一种需求, 我们需要在后台(console)去对商品(product)做一些操做, 而这里我们只能够使用到公共的service方法, 那么怎么调用product中service的实现呢?
项目结构:
公共service方法:
TestTbService.java:
1 package cn.itcast.core.service;
2
3 import cn.itcast.core.bean.TestTb;
4
5 public interface TestTbService {
6 public void insertTestTb(TestTb testTb);
7 }
product中的service实现类:
TestTbService.java:
1 package cn.itcast.core.service;
2
3 import org.springframework.beans.factory.annotation.Autowired;
4 import org.springframework.stereotype.Service;
5 import org.springframework.transaction.annotation.Transactional;
6
7 import cn.itcast.core.bean.TestTb;
8 import cn.itcast.core.dao.TestTbDao;
9
10 @Service("testTbService")
11 @Transactional
12 public class TestTbServiceImpl implements TestTbService {
13
14 @Autowired
15 private TestTbDao testTbDao;
16
17 //保存
18 public void insertTestTb(TestTb testTb){
19 testTbDao.insertTestTb(testTb);
20 }
21 }
在console中使用product中的service实现类:
CenterController.java:
1 package cn.itcast.core.controller;
2
3 import java.util.Date;
4
5 import org.junit.runners.model.TestTimedOutException;
6 import org.springframework.beans.factory.annotation.Autowired;
7 import org.springframework.stereotype.Controller;
8 import org.springframework.ui.Model;
9 import org.springframework.web.bind.annotation.RequestMapping;
10
11 import cn.itcast.core.bean.TestTb;
12 import cn.itcast.core.service.TestTbService;
13
14 @Controller
15 public class CenterController {
16
17 @Autowired
18 private TestTbService testTbService;
19
20 //测试
21 @RequestMapping(value = "/test/index.do")
22 public void index(Model model){
23
24 TestTb testTb = new TestTb();
25 testTb.setName("范冰冰");
26 testTb.setBirthday(new Date());
27
28 testTbService.insertTestTb(testTb);
29
30 }
31 }
如果这样直接调用能够行的通吗? 当然是不行的, 在console里面定义的只是service方法, 那么这里是怎么直接调用到了product中的service实现类呢?
当然了, 这里就需要一些配置文件了: 首先是需要在product中注册服务: dubbo-provider.xml:
1 <beans xmlns="http://www.springframework.org/schema/beans"
2 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
3 xmlns:context="http://www.springframework.org/schema/context"
4 xmlns:aop="http://www.springframework.org/schema/aop"
5 xmlns:tx="http://www.springframework.org/schema/tx"
6 xmlns:task="http://www.springframework.org/schema/task"
7 xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
8 xsi:schemaLocation="http://www.springframework.org/schema/beans
9 http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
10 http://www.springframework.org/schema/mvc
11 http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
12 http://www.springframework.org/schema/context
13 http://www.springframework.org/schema/context/spring-context-4.0.xsd
14 http://www.springframework.org/schema/aop
15 http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
16 http://www.springframework.org/schema/tx
17 http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
18 http://www.springframework.org/schema/task
19 http://www.springframework.org/schema/task/spring-task-4.0.xsd
20 http://code.alibabatech.com/schema/dubbo
21 http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
22
23
24 <!-- 整合Dubbo -->
25 <!-- 第一步：Dubbo起名称 计算用此名称来区分 -->
26 <dubbo:application name="babasport-service-product"/>
27 <!-- 第二步：中介 注册中心: zookeeper redis ... -->
28 <!-- <dubbo:registry address="192.168.200.128:2181,192.168.200.129:2181,192.168.200.130:2181" protocol="zookeeper"/> -->
29 <dubbo:registry address="192.168.200.128:2181" protocol="zookeeper"/>
30 <!-- 第三步：设置dubbo的端口号 192.168.40.88:20880/接口 -->
31 <dubbo:protocol name="dubbo" port="20880"/>
32 <!-- 第四步：设置服务提供方 提供的接口 -->
33 <dubbo:service interface="cn.itcast.core.service.TestTbService" ref="testTbService"/>
34
35 </beans>
接下来就是在console中使用了: 服务消费方: dubbo-cusmer.xml:
1 <beans xmlns="http://www.springframework.org/schema/beans" 2 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" 3 xmlns:context="http://www.springframework.org/schema/context" 4 xmlns:aop="http://www.springframework.org/schema/aop" 5 xmlns:tx="http://www.springframework.org/schema/tx" 6 xmlns:task="http://www.springframework.org/schema/task" 7 xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" 8 xsi:schemaLocation="http://www.springframework.org/schema/beans 9 http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 10 http://www.springframework.org/schema/mvc 11 http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd 12 http://www.springframework.org/schema/context 13 http://www.springframework.org/schema/context/spring-context-4.0.xsd 14 http://www.springframework.org/schema/aop 15 http://www.springframework.org/schema/aop/spring-aop-4.0.xsd 16 http://www.springframework.org/schema/tx 17 http://www.springframework.org/schema/tx/spring-tx-4.0.xsd 18 http://www.springframework.org/schema/task 19 http://www.springframework.org/schema/task/spring-task-4.0.xsd 20 http://code.alibabatech.com/schema/dubbo 21 http://code.alibabatech.com/schema/dubbo/dubbo.xsd"> 22 23 <!-- 整合Dubbo --> 24 <!-- 第一步：Dubbo起名称 计算用此名称来区分 --> 25 <dubbo:application name="babasport-console"/> 26 <!-- 第二步：中介 注册中心 zookeeper redis ... --> 27 <!--<dubbo:registry address="192.168.200.128:2181,192.168.200.129:2181,192.168.200.130:2181" protocol="zookeeper"/> --> 28 <dubbo:registry address="192.168.200.128:2181" protocol="zookeeper"/> 29 <!-- 第三步：调用服务提供方 提供的接口 --> 30 <dubbo:reference interface="cn.itcast.core.service.TestTbService" id="testTbService"/> 31 32 </beans>
剩下的就是启动服务了:
注意先启动服务提供方, 然后再启动服务消费方.
