The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption
Modify the contents of java.security
You need to find java.security in the java installation directory, the default path :C:\Program Files\Java\jdk1.8.0_361\jre\lib\security
Modify jdk.tls.disabledAlgorithms
jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048
# 这个是原有的配置（已封存）
#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
# 这个是修改后的配置，注意这里将TLSv1, TLSv1.1去掉以确保SSL加密生效
jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, \
DH keySize < 1024, EC keySize < 224, DES40_CBC, RC4_40, \
include jdk.disabled.namedCurves
Modify jdk.tls.legacyAlgorithms
# 这个是原有配置（已封存）
#jdk.tls.legacyAlgorithms= \
# K_NULL, C_NULL, M_NULL, \
# DH_anon, ECDH_anon, \
# RC4_128, RC4_40, DES_CBC, DES40_CBC, \
# 3DES_EDE_CBC
# 这个是修改后的配置，这里将“3DES_EDE_CBC”删除了
jdk.tls.legacyAlgorithms= \
K_NULL, C_NULL, M_NULL, \
DH_anon, ECDH_anon, \
RC4_128, RC4_40, DES_CBC, DES40_CBC

Supplementary Note
In addition, I tried several versions of the SQLSever driver version, and finally determined the version mssql-jdbc8.2.2.jre8
mssql-jdbc8.2.2.jre8 download link: https://download.microsoft.com/download/5/3/f/53fcc3e2-e91f-48f4-bed6-5d79e4fc9fbe/sqljdbc_8.2.2.0_chs.zip
The above are some of the problems I personally encountered and the solutions to share with you, I hope it will be helpful to you
