java - Sonar : Instance methods should not write to "static" fields

Question

我从 Sonar 收到此提示:实例方法不应写入“静态”字段

我不太确定需要更改什么来解决此问题。

“SemaMonitorProxy.applicationContext”是否必须等于静态方法？

public class SemaMonitorProxy implements ApplicationContextAware {

    private static ApplicationContext applicationContext = null;

    public void registerFailedLoginAttempt(HttpServletRequest request, HttpServletResponse response) {
        final SemaMonitor semaMonitor = applicationContext.getBean(SemaMonitor.class);
        semaMonitor.registerFailedLoginAttempt(request, response);
    }

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        SemaMonitorProxy.applicationContext = applicationContext;
    }
}

Answer 1

其实这个方法:

@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
    SemaMonitorProxy.applicationContext = applicationContext;
}

是写入静态字段的实例方法:

private static ApplicationContext applicationContext

您不能将上述方法设为静态。因此，唯一的解决方案是从 applicationContext 声明中删除 static 关键字。

private ApplicationContext applicationContext
