奇怪怎么-Djava.security.egd=file:/dev/./urandom参数没起作用,仍使用/dev/random作为随机数的熵池,时间久或调用频繁的话熵池很容易不够用而导致阻塞;于是看了一下 SecureRandom.getInstanceStrong()的文档: Returns a SecureRandom object that was selected by using the algorithms/providers specified in the secur...
(1)导包:import java.util.Scanner; (2)新建对象:Scanner scan = new Scanner(System.in); (3)使用功能: int num = scan.nextInt(); double num = scan.nextDouble(); String name = scan.next(); 练习代码: public static void main(String[] args) { Scanner sc = new Scanner(System.in); Sys...
要解决这个问题,可以通过配置JRE使用非阻塞的Entropy Source,在bin/ 中加入这么一行:JAVA_OPTS=" -Djava.security.egd=file:/dev/./urandom"即可。 加入后再启动tomcat,整个启动下降到仅耗时Server startup in 912 ms。
A SecureRandom object can be obtained using the getInstance() method in class java.security.SecureRandom. This SecureRandom object is useful in implementing the Random Number Generator (RNG) algorithm that is specified. The getInstance() method requires a single parameter i.e. the Random Number ...
Learn about the SecureRandom getProvider method in Java, its usage, and how it helps in providing a secure random number generator.

加入后再启动Tomcat,整个启动耗时下降到Server startup in 2912 ms。 2)在JVM环境中解决 打开$JAVA_PATH/jre/lib/security/java.security这个文件,找到下面的内容: securerandom.source=file:/dev/random 替换成 securerandom.source=file:/dev/urandom
