SpringBoot开发案例之整合Dubbo提供者(一)

既然是开发案例，显然不会扯那么多老婆舌，有不清楚这两个东东的请自行百度。

开发环境

JDK1.7、Maven、Eclipse、SpringBoot1.5.1、Dubbo2.8.4

User.java 一定要实现序列化接口

public class User implements Serializable {

private static final long serialVersionUID = -1L;

private String username;
private Integer age;

public User(String username, Integer age) {
this.username = username;
this.age = age;
}

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
}

public Integer getAge() {
return age;
}

public void setAge(Integer age) {
this.age = age;
}
}

IUserService.java 接口

public interface IUserService {
void saveUser(User user);
}

UserServiceImpl.java 实现

@Service("userService")
public class UserServiceImpl implements IUserService {
@Override
public void saveUser(User user) {
System.out.println("保存用户:"+user.getUsername());
}
}

dubbo.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- 提供方应用信息 -->
<dubbo:application name="springBoot_dubbo_provider"  />

<!-- 注册中心服务地址 -->
<dubbo:registry  protocol="zookeeper" address="${dubbo.registry.address}"  check="false" />

<!-- 用dubbo协议-->
<dubbo:protocol name="dubbo" port="-1" dispather="all" check="false" />

<dubbo:provider timeout="10000"  threads="10" threadpool="fixed"   loadbalance="roundrobin"/>

<!-- 声明需要暴露的服务接口 -->
<dubbo:service interface="com.itstyle.dubbo.service.IUserService" ref="userService"/>

</beans>

application.properties

# 项目contextPath，一般在正式发布版本中，我们不配置
server.context-path=/provider
# 错误页，指定发生错误时，跳转的URL。请查看BasicErrorController源码便知
server.error.path=/error
# 服务端口
server.port=8080
# session最大超时时间(分钟)，默认为30
server.session-timeout=60
# 该服务绑定IP地址，启动服务器时如本机不是该IP地址则抛出异常启动失败，只有特殊需求的情况下才配置
# server.address=192.168.16.11

# tomcat最大线程数，默认为200
server.tomcat.max-threads=800
# tomcat的URI编码
server.tomcat.uri-encoding=UTF-8

#ZooKeeper
dubbo.registry.address=192.168.1.180:2181
logging.level.root=INFO

SpringbootDubboApplication.java 测试类

@SpringBootApplication
@ComponentScan(basePackages={"com.itstyle.dubbo"})
@ImportResource({"classpath:dubbo.xml"})
public class SpringbootDubboApplication implements CommandLineRunner {
@Autowired
private IUserService userService;

public static void main(String[] args) {
SpringApplication.run(SpringbootDubboApplication.class, args);
}
@Override
public void run(String... args) throws Exception {
User user = new User("张三",19);
userService.saveUser(user);
}
}

此时，我们运行SpringbootDubboApplication类，如下结果说明成功：



然后使用ZooInspector查看zookeeper信息，会发现注册了一个提供者：
