现象：

使用DataGrip连接数据库时，提示如下错误：

The server selected protocol version TLS10 is not accepted by client preferences [TLS13, TLS12]”

解决：

打开DataGrip配置文件：

安装路径\JetBrains\DataGrip 2021.3.4\jbr\conf\security\java.security

搜索：jdk.tls.disabledAlgorithms

注意:不带#的行

 # Example: #   jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048, \ #       rsa_pkcs1_sha1, secp224r1 jdk.tls.disabledAlgorithms=SSLv3,TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \   DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \   include jdk.disabled.namedCurves 

删除里面的TLSv1:

# Example: #   jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048, \ #       rsa_pkcs1_sha1, secp224r1 jdk.tls.disabledAlgorithms=SSLv3,TLSv1.1, RC4, DES, MD5withRSA, \   DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \   include jdk.disabled.namedCurves 

回到DataGrip,点击连接测试，成功连接
