问题描述:

(1)javaWeb项目启动中,还没启动完成,在下面这个类加载另一个Bean类,

(2)通过getBean方法获取到该Bean,可以获取到,不为null

(3)但是,调用该Bean的方法insertSelective()方法,进不去该方法

 

 

解决方法:

项目启动时,延迟5秒即可,下面这个类等待5秒,等它调用的Bean加载完,就能调用了

 

public enum RfidRecordStorage {
    INSTANCE;
    private static Logger logger = Logger.getLogger(RfidRecordStorage.class);
    
    static {
        try {
            Thread.sleep(5000);
        } catch (InterruptedException e) {
            logger.error("启动工程时休眠RfidRecordStorage类失败!");
        }
    }
    
    public synchronized int store(AppRfidPassRecord appRfidPassRecord) {

        AppRfidPassRecordService appRfidPassRecordService = 
                (AppRfidPassRecordService) SpringContextUtils.getApplicationContext().getBean("appRfidPassRecordService");
        
        
        int resultNum = 0;
        resultNum = appRfidPassRecordService.insertSelective(appRfidPassRecord);
        return resultNum;
    }
}
