2.处理：

第一步:

jdbc:sqlserver://ip:port;DatabaseName=database;trustServerCertificate=true

添加：;trustServerCertificate=true属性

第二步：

找到jdk安装目录：

C:\Program Files\Java\jdk-17\conf\security

文件：java.security

找到：

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, DTLSv1.0, RC4, DES, \
    MD5withRSA, DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL

替换：

jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 1024, \
    EC keySize < 224, DES40_CBC, RC4_40, 3DES_EDE_CBC

第三步：

添加启动配置

java -Djdk.tls.client.protocols="TLSv1,TLSv1.1,TLSv1.2,TLSv1.3" -jar xxxx.jar
