java - Spring创建bean时出错

Question

我收到以下错误

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'preTransactionHandlerPool' defined in class com.fg.transbridge.processor.spring.ContextConfiguration: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException

我已经有了 preTransactionHandlerPool bean。

@Bean(name = "preTransactionHandlerPool")
    public ThreadPoolTaskExecutor preTransactionHandlerPool() {

        LOGGER.info("Initializing preTransactionHandlerPool");
        ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor();
        threadPoolTaskExecutor.setCorePoolSize(preTransCorePoolSize);
        threadPoolTaskExecutor.setMaxPoolSize(preTransMaxPoolSize);
        threadPoolTaskExecutor.setWaitForTasksToCompleteOnShutdown(preWaitForCompleteShutDown);
        LOGGER.debug("Initiated preTransactionHandlerPool");
        return threadPoolTaskExecutor;
    }

这可能是什么原因？非常感谢您的帮助。

谢谢

好的，找到正确答案了。该方法存在一些错误。在我的例子中，传递的值应该是 setMaxPoolSize > setCorePoolSize。
