项目
采用的是apollo配置,监听apollo配置是否修改,如果有变动,则调用线程池的修改参数方法
关键代码
ThreadPoolTaskExecutor.setCorePoolSize(cpuCoreSize);
ThreadPoolTaskExecutor.setMaxPoolSize(maxCoreSize);
public static final String CPU_CORE_SIZE = "cpuCoreSize";
public static final String MAX_CORE_SIZE = "maxCoreSize";
@ApolloConfigChangeListener("")
public void doThreadChangeHandler(ConfigChangeEvent changeEvent) throws Exception {
if(changeEvent.isChanged(CPU_CORE_SIZE) || changeEvent.isChanged(MAX_CORE_SIZE)) {
ThreadPoolTaskExecutor asyncPool = ThreadPoolUtil.getAsyncPool();
log.info("doThreadChangeHandler start : old cpuCoreSize : {},old maxPoolSize : {}", asyncPool.getCorePoolSize(), asyncPool.getMaxPoolSize());
int cpuCoreSize = Integer.valueOf(changeEvent.getChange(CPU_CORE_SIZE).getNewValue());
int maxCoreSize = Integer.valueOf(changeEvent.getChange(MAX_CORE_SIZE).getNewValue());
ThreadPoolUtil.getAsyncPool().setCorePoolSize(cpuCoreSize);
ThreadPoolUtil.getAsyncPool().setMaxPoolSize(maxCoreSize);
log.info("doThreadChangeHandler start : new cpuCoreSize : {},new maxPoolSize : {}", asyncPool.getCorePoolSize(), asyncPool.getMaxPoolSize());
}
}
