当我加大提供者的sleep时间时：
package com.ghy.www.my.loadbalance.provider.service;
import com.ghy.www.api.IService3;
import org.springframework.beans.factory.annotation.Value;
public class HelloService3 implements IService3 {
@Value("${server.port}")
private int portValue;
@Override
public String getHello(String username) {
System.out.println("HelloService3 portValue=" + portValue + "
username=" + username);
if (portValue == 8085) {
try {
Thread.sleep(800);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
if (portValue == 8086) {
try {
Thread.sleep(700);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
if (portValue == 8087) {
try {
Thread.sleep(10);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
return "hello3 " + username + " port=" + portValue;
}
}
执行消费者后，提供者出现警告：
Thread pool is EXHAUSTED! Thread Name:
DubboServerHandler-192.168.30.188:20882, Pool Size: 200 (active: 200, core:
200, max: 200, largest: 200), Task: 991 (completed: 791), Executor

这个实验不管我如何测，都测不出理想中的效果(由于8085最慢，所以请求到8085的请求是“超级”少的)。
