这个问题异常信息较多，排查了很久，问题的原因是Caused by: CertificateNotYetValidException: NotBefore: Tue Dec 10 05:58:17 CST 2019，但是由于对java异常机制不够熟悉，导致没有找到根本的异常原因，所以排查了很久，因此试验总结下异常的相关信息

异常总结

单个异常

public class ExceptionTest {public static void main(String[] args) {new ExceptionTest().g();}public void g() throws MyException1{throw new MyException1();}
}

抛出异常信息如下

Exception in thread "main" ption.st.exception.ExceptionTest.g(ExceptionTest.java:32)st.exception.ExceptionTest.main(ExceptionTest.java:12)

异常堆栈信息最原始的异常在最上方

多个异常

public class ExceptionTest {public static void main(String[] args) {try {new ExceptionTest().f();} catch (MyException2 e) {e.printStackTrace();}}public void f() throws MyException2{try {g();} catch (MyException1 e) {e.printStackTrace();throw new MyException2();}}public void g() throws MyException1{throw new MyException1();}
}

打印了两遍异常信息

一般后面打印的异常信息是由前面的异常导致的，先抛出MyException1并打印，并转换位MyException2后重新打印，所以一般只用关注上面的异常即可

异常链

public class ExceptionTest {public static void main(String[] args) {try {new ExceptionTest().f();} catch (MyException2 e) {e.printStackTrace();}}public void f() throws MyException2{try {g();} catch (MyException1 e) {e.printStackTrace();throw new MyException2(e);}}public void g() throws MyException1{throw new MyException1();}
}

异常信息如下，具有异常链

MyException2是由MyException1引起的，由于 throw new MyException2(e);中把异常信息带出，所以出现Caused by，如果有异常链信息，大部分需要关注最原始的异常信息
