准备三台服务器
n 服务器A
Ip 172.16.17.56
端口 1185
n 服务器B
Ip 172.16.17.51
端口 1185
n 服务器C
Ip 172.16.17.52
端口 1185
假设我们已经定义了业务组件test.A和test.B,分别实现接口test.ServiceInf。服务中定义了方法handle(),返回值为Object,方法代码如下:
public Object handle(){
return new Integer(1);
}
在A,B,C三台服务器上分别部署管理服务managerid,建立配置文件service-assemble.xml内容如下:
<manager-config>
<manager id="managerid" //管理服务id
singlable="true" //单列模式
>
<provider type="provider_a" //provider实现a
class="test.A" />
<provider type="provider_b" //provider实现b
class="test.B" />
<transactions>
<method name="handle" txtype="REQUIRED_TRANSACTION"/>
</transactions>
</manager>
<manager-config>
然后将service-assemble.xml导入到主配置文件manager-provider.xml文件:
<manager-config>
<managerimport file="com/chinacreator/spi/rpc/service-assemble.xml" />
</manager-config>
在主配置文件manager-provider.xml中添加以下配置,作为远程管理组件启用的控制开关:
<manager-config>
<properties>
<property name="cluster_enable" value="true"/> //启用远程管理组件
<property name="cluster_mbean_enable" value="true"/> //启用远程管理组件的mbean监控功能,目前未使用
<property name="cluster_name" value="Cluster"/> //远程管理组件名称
</properties>
<managerimport file="com/chinacreator/spi/rpc/service-assemble.xml" />
</manager-config>
配置服务器间通讯端口和组播地址
在远程管理组件的配置文件etc/META-INF/replSync-service-aop.xml
中修改bind_port属性:
bind_port="1185"
修改组播地址:
mcast_addr="228.10.10.178"

System.out.println((e - s) / 1000 + "秒");

public static void testsinglerpcCall() {

System.out.println(object);

System.out.println(BaseSPIManager.getRPCResult("172.16.17.56", "1185", object));
long e = System.currentTimeMillis();
System.out.println((e - s) / 1000 + "秒");
} catch (SPIException e) {
e.printStackTrace();
}
}
}
分别在每台服务器上运行类com.chinacreator.remote.RunAop的主方法,既可以启动服务器。
注意,客服端不要启动服务器。
Test.testAllrpcCall();
Test.testMutirpcCall();
Test.testsinglerpcCall();
