近来开发一个机遇java的C/S架构的项目，需要考虑到并发量的问题，不知道Executor类的性能如何，能经得起多少的并发量呢？手写的线程池（足够好的话）会比它强吗
java
------解决方案--------------------
这个受你的服务器配置及应用场景影响了
发你段手工写的代码，你可以动态改变线程池的大小，保持连接的时间等参数，有点定制化的意思
public class ThreadPoolTaskExecutor extends CustomizableThreadFactory implements ExecutorService, SchedulingTaskExecutor, Executor, BeanNameAware, InitializingBean, DisposableBean {
protected final Logger logger = LoggerFactory.getLogger(getClass());
private final Object poolSizeMonitor = new Object();
private int corePoolSize = 1;
private int maxPoolSize = Integer.MAX_VALUE;
private int keepAliveSeconds = 60;
private boolean allowCoreThreadTimeOut = false;
private int queueCapacity = Integer.MAX_VALUE;
private ThreadFactory threadFactory = this;
// 替换为调用方执行的handler
private RejectedExecutionHandler rejectedExecutionHandler = new ThreadPoolExecutor.CallerRunsPolicy();
private boolean waitForTasksToCompleteOnShutdown = false;
private boolean threadNamePrefixSet = false;
private String beanName;
