换了个OpenJDK8u442-b06，启动项目报错：

打开jdk8u442-b06\jre\lib\security\java.security文件，修改jdk.tls.disabledAlgorithms。
jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \
DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
ECDH, \
include jdk.disabled.namedCurves
改为：
jdk.tls.disabledAlgorithms=SSLv3, TLSv1.1, RC4, DES, MD5withRSA, \
DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
ECDH, \
include jdk.disabled.namedCurves
