通过查找资料，原来是jdk中 jdk.tls.disabledAlgorithms 如果有TLSv1、TLSv1.1、3DES_EDE_CBC，要删除才可以

一、首先，找到你项目用JDK：

JDK目录在C盘如上

二、找到C:Program FilesJavajdk-1.8jrelibsecurityjava.security 这个文件，如果有TLSv1、TLSv1.1、3DES_EDE_CBC，要删除后再保存，注意以管理员形式保存，在修改的时候要注意此时要把项目程序关闭

改后部分代码如下：

#   KeyLength:
#       Integer value of the algorithm's key length in bits
#
# Note: This property is currently used by the JDK Reference
# implementation. It is not guaranteed to be examined and used by other
# implementations.
#
# See "jdk.certpath.disabledAlgorithms" for syntax descriptions.
#
jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize 

删除后重新保存后，再运行程序，就能解决上面报错。
