Warning: Establishing SSL connection without server's identity verification is not recommended
提问by relangi rajeshwari
When connecting a MySQL database I get the warning below:
连接 MySQL 数据库时，我收到以下警告：
Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
不建议在没有服务器身份验证的情况下建立 SSL 连接。根据 MySQL 5.5.45+、5.6.26+ 和 5.7.6+ 要求，如果未设置显式选项，则必须默认建立 SSL 连接。为了符合不使用 SSL 的现有应用程序，verifyServerCertificate 属性设置为“false”。您需要通过设置 useSSL=false 来显式禁用 SSL，或者设置 useSSL=true 并为服务器证书验证提供信任库。
please help me out from this problem

try{
Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/INTtech","root","root");
Statement st=con.createStatement();
int i=st.executeUpdate("create table Author(AID int primary key,Aname varchar(20),AContact no int,ACountry string)");
System.out.println("Table is created"+i);
con.close();

Put the useSSL=false at the end of the name database:
将 useSSL=false 放在名称数据库的末尾：
Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/INTtech?useSSL=false","root","root");
