我的代码：

package com.Test;

import java.sql.*;

public class Test {
    public static void main(String[] args) {
        String connectionUrl ="jdbc:sqlserver://116.62.237.109:1433;databaseName=testDB;integratedSecurity=false;";
        try {
            Connection con = DriverManager.getConnection(connectionUrl, "sa", "!QAZ@WSX3edc4rfv");
            Statement stmt = con.createStatement();
            System.out.println("ok");

        } catch (SQLException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

解决方法一：
如果开发工具添加的是jdk，比如我的就在D:\Program Files\software\Java\jdk1.8.0_191\jre\lib\security下面的java.security文件下，将jdk.tls.disabledAlgorithms和jdk.tls.legacyAlgorithms 后面的3DES_EDE_CBC给删掉，就可以了。如果开发工具添加的是jre，则把jre下面的java.security文件这样改。

可以看到原先的问题已经解决了吗，出现的这个问题是数据库登陆失败问题。
