以下是Spring Boot Dubbo直连模式的代码示例:
1. 首先在pom.xml文件中添加Dubbo和Zookeeper的依赖:
```xml
<dependency>
<groupId>com.alibaba.spring.boot</groupId>
<artifactId>dubbo-spring-boot-starter</artifactId>
<version>2.0.0</version>
</dependency>
<dependency>
<groupId>com.github.sgroschupf</groupId>
<artifactId>zkclient</artifactId>
<version>0.10</version>
</dependency>
```
2. 在application.properties文件中配置Dubbo和Zookeeper的相关参数:
```properties
# Dubbo
dubbo.application.name=demo-service
dubbo.registry.address=zookeeper://127.0.0.1:2181
# Zookeeper
zookeeper.client.connect-string=127.0.0.1:2181
```
3. 创建一个Dubbo服务接口:
```java
public interface DemoService {
String sayHello(String name);
}
```
4. 实现Dubbo服务接口:
```java
@Service(version = "1.0.0")
public class DemoServiceImpl implements DemoService {
@Override
public String sayHello(String name) {
return "Hello, " + name;
}
}
```
5. 在Dubbo服务提供者的启动类中,使用@DubboComponentScan注解扫描Dubbo服务实现类:
```java
@SpringBootApplication
@DubboComponentScan("com.example.demo.service")
public class ProviderApplication {
public static void main(String[] args) {
SpringApplication.run(ProviderApplication.class, args);
}
}
```
6. 在Dubbo服务消费者的启动类中,使用@DubboComponentScan注解扫描Dubbo服务接口:
```java
@SpringBootApplication
@DubboComponentScan("com.example.demo.service")
public class ConsumerApplication {
public static void main(String[] args) {
SpringApplication.run(ConsumerApplication.class, args);
}
}
```
7. 在Dubbo服务消费者中,通过直连方式调用Dubbo服务:
```java
@RestController
public class DemoController {
@Reference(version = "1.0.0", url = "dubbo://127.0.0.1:20880")
private DemoService demoService;
@GetMapping("/hello")
public String sayHello(@RequestParam String name) {
return demoService.sayHello(name);
}
}
```
在@Reference注解中,设置version参数为Dubbo服务的版本号,设置url参数为Dubbo服务的地址。
以上就是Spring Boot Dubbo直连模式的代码示例。
