我这里有一个代码,这是来自camel官方网站的示例代码:
package org.apache.camel.processor;
import org.apache.camel.AsyncCallback;
import org.apache.camel.ContextTestSupport;
import org.apache.camel.Exchange;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.component.mock.MockEndpoint;
import org.apache.camel.processor.loadbalancer.LoadBalancerSupport;
public class CustomLoadBalanceTest extends ContextTestSupport {
protected MockEndpoint x;
protected MockEndpoint y;
protected MockEndpoint z;
@Override
protected void setUp() throws Exception {
super.setUp();
x = getMockEndpoint("mock:x");
y = getMockEndpoint("mock:y");
z = getMockEndpoint("mock:z");
}
protected RouteBuilder createRouteBuilder() {
return new RouteBuilder() {
public void configure() {
// START SNIPPET: e1
from("direct:start")
// using our custom load balancer
.loadBalance(new MyLoadBalancer())
.to("mock:x", "mock:y", "mock:z");
// END SNIPPET: e1
}
};
}
public void testCustomLoadBalancer() throws Exception {
x.expectedBodiesReceived("x", "x", "x");
y.expectedBodiesReceived("y", "y");
z.expectedBodiesReceived("foo", "bar", "baz");
template.sendBody("direct:start", "x");
template.sendBody("direct:start", "y");
template.sendBody("direct:start", "foo");
template.sendBody("direct:start", "bar");
template.sendBody("direct:start", "y");
template.sendBody("direct:start", "x");
template.sendBody("direct:start", "x");
template.sendBody("direct:start", "baz");
assertMockEndpointsSatisfied();
}
// START SNIPPET: e2
public static class MyLoadBalancer extends LoadBalancerSupport {
public boolean process(Exchange exchange, AsyncCallback callback) {
String body = exchange.getIn().getBody(String.class);
try {
if ("x".equals(body)) {
getProcessors().get(0).process(exchange);
} else if ("y".equals(body)) {
getProcessors().get(1).process(exchange);
} else {
getProcessors().get(2).process(exchange);
}
} catch (Throwable e) {
exchange.setException(e);
}
callback.done(true);
return true;
}
}
// END SNIPPET: e2
}
此代码用于使用apache camel执行自定义负载平衡。 我希望apache camel能够监听本地主机和端口并平衡通过IPaddress和端口号指定的服务器之间的负载。服务器端安装了tomcat,它会监听请求。
那么如何修改以下代码以满足我的要求。 我对骆驼有点新鲜。非常感谢任何帮助。
提前感谢。 干杯!!
答案 0 :(得分:1)
这是一些使负载均衡器工作的路由代码 但是,我没有检查自定义负载平衡类的内部,但这应该是直截了当的。
from("jetty://http://0.0.0.0:8080/test")
.loadBalance(new MyLoadBalancer())
.to("http://tcserver1:8080/hello","http://tcpserver2:8080/hello","http://tcpserver3:8080/hello");
