我有一个方法可以访问数据库并将大量记录提取到内存中进行处理.在我获取记录之后,在开始处理之前,我收到以下日志消息.这是什么意思 ？
164575.034: [GC (Allocation Failure) 4937664K->3619624K(5602816K), 0.0338580 secs]
选项:
java.opts=-d64 -Xmx8g -XX:+PrintGCTimeStamps -verbose:gc -XX:MaxPermSize=512m -XX:+UseParallelGC -XX:+UseParallelOldGC
声纳给我的信息是:
恶意代码漏洞 - 字段应该是针对静态数组的包保护
FORMATS.
为什么此代码被视为恶意代码？我有一个公共类来存储所有常量.
public class Constants
{
/*
all the public static final constants of primitive datatypes for which
there is no sonar warning.
*/
public static final String[] FORMATS = new String[] {
"yyyy-MM-dd HH:mm:ss.S z",
"yyyy-MM-dd HH:mm:ss.S"
}

我希望helpContent拥有所有风格itemContent.我将如何helpContent继承itemContent？
