springboot整合dubbo
孤依寒 人气:0Dubbo是Alibaba开源的分布式服务框架,它最大的特点是按照分层的方式来架构,使用这种方式可以使各个层之间解耦合(或者最大限度地松耦合)。从服务模型的角度来看,Dubbo采用的是一种非常简单的模型,要么是提供方提供服务,要么是消费方消费服务,所以基于这一点可以抽象出服务提供方(Provider)和服务消费方(Consumer)两个角色。
1.服务提供者配置
//需要额外引入的jar包 提供者 <dependency> <groupId>com.alibaba.boot</groupId> <artifactId>dubbo-spring-boot-starter</artifactId> <version>0.2.0</version> </dependency> <dependency> <groupId>com.github.sgroschupf</groupId> <artifactId>zkclient</artifactId> <version>0.1</version> </dependency>
spring配置方式
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd"> <dubbo:application name="user-service-provider"></dubbo:application> <!-- 指定注册中心的地址,将来服务提供者要向注册中心进行注册--> <dubbo:registry address="zookeeper://192.168.192.3:2181"></dubbo:registry> <!-- 指定将来服务消费者消费我的时候使用的rpc协议 --> <dubbo:protocol name="dubbo" port="11123"></dubbo:protocol> <!-- 服务发布 --> <bean id="userService" class="com.oracle.shop.user.service.impl.UserServiceImpl"></bean> <dubbo:service interface="com.oracle.shop.user.service.UserService" ref="userService"></dubbo:service> </beans>
springboot配置方式
#dubbo的配置 #服务名 dubbo.application.name=user-provider #注册中心地址 dubbo.registry.address=zookeeper://192.168.192.3:2181 #使用的协议以及端口号 dubbo.protocol.name=dubbo dubbo.protocol.port=11111
发布服务的方式
在相应的实现类上添加注解
import com.alibaba.dubbo.config.annotation.Service; import com.oracle.shopping.user.mapper.MenuMapper; import com.oracle.shopping.user.po.Menu; import com.oracle.shopping.user.service.MenuService; import javax.annotation.Resource; @Service //dubbo的注解表示发布该类 @org.springframework.stereotype.Service//spring的注解表示会在启动时实例化该类 public class MenuServiceImpl implements MenuService { @Resource private MenuMapper menuMapper; @Override public int deleteByPrimaryKey(String id) { return menuMapper.deleteByPrimaryKey(id); } @Override public int insert(Menu record) { return menuMapper.insert(record); } @Override public int insertSelective(Menu record) { return menuMapper.insertSelective(record); } @Override public Menu selectByPrimaryKey(String id) { return menuMapper.selectByPrimaryKey(id); } @Override public int updateByPrimaryKeySelective(Menu record) { return menuMapper.updateByPrimaryKeySelective(record); } @Override public int updateByPrimaryKey(Menu record) { return menuMapper.updateByPrimaryKey(record); } }
启动类中添加dubbo的扫包器,设置扫描路径
@SpringBootApplication @MapperScan("com.oracle.shopping.user.mapper") @EnableTransactionManagement @DubboComponentScan("com.oracle.shopping.user.service.impl") public class UserProviderApp { public static void main(String[] args) { SpringApplication.run(UserProviderApp.class, args); } }
2.服务消费者订阅
<dependency> <groupId>com.alibaba.boot</groupId> <artifactId>dubbo-spring-boot-starter</artifactId> <version>0.2.0</version> </dependency> <dependency> <groupId>com.github.sgroschupf</groupId> <artifactId>zkclient</artifactId> <version>0.1</version> </dependency>
spring配置方式
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd"> <dubbo:application name="user-web-consumer"></dubbo:application> <!-- 指定注册中心的地址,将来服务提供者要向注册中心进行注册--> <dubbo:registry address="zookeeper://192.168.192.3:2181"></dubbo:registry> <!-- 订阅具体服务,让dubbo帮咱们生成动态代理客户端对象--> <dubbo:reference interface="com.oracle.shop.user.service.UserService" id="userService"></dubbo:reference> <dubbo:reference interface="com.oracle.shop.order.service.OrderService" id="orderService"></dubbo:reference> </beans>
在controller中进行依赖注入和调用
@Controller @RequestMapping("/user") public class UserController { //通过动态代理的方式生成的动态代理类 @Autowired(required = false) private UserService userService; //不进行检查,防止报错无法运行 @Autowired(required = false) private OrderService orderService; @RequestMapping("/a") public @ResponseBody User detail(){ return userService.findUserById(1); } @RequestMapping("/b") public @ResponseBody Orders details(){ return orderService.findUserById(1); } }
springboot配置方式
#指定自己的名称 dubbo.application.name=user-consumer #指定注册中心的地址 dubbo.registry.address=zookeeper://192.168.192.3:2181
在controller当中使用注解声明要使用的服务(实现类)
@RestController @RequestMapping("/user") public class UserController { //表示要使用的服务 @Reference(interfaceName = "com.oracle.shopping.user.service.UserService") private UserService userService; @Autowired private RedisTemplate redisTemplate; @RequestMapping("/detail") public User detail(String id){ return userService.selectByPrimaryKey(id); } }
启动类中设置dobbo注解的扫描路径
@SpringBootApplication @DubboComponentScan("com.oracle.shopping.user.controller") public class UserConsumerApp { public static void main(String[] args) { SpringApplication.run(UserConsumerApp.class ); } }
