Question

我正在尝试使Talend Open Studio 7.1与MySQL Server 8.0之间建立连接。我是使用Talend的第一天，但是当我使用tDBConnection与数据库执行连接（数据库为'world'，即安装了MySQL的示例）时，出现以下错误：

You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

我试图重新安装MySQL Server和jConnector，但是没有任何改变。似乎无法连接到主机“ localhost”。我试图用谷歌搜索错误消息，但是我什么也没得到。预先感谢您的帮助。

Answer 1

使用JDBC连接类型并为JDBC添加jar文件

示例

jdbc:mysql://localhost:3306/sakila?noDatetimeStringSync=true&serverTimezone=UTC

驱动程序

mysql-connector-java-8.0.11.jar

Answer 2

您需要在其他JDBC参数中提及服务器时区。为了摆脱SSL Warning，还有一个参数要传递。就我而言，我的服务器时间与本地计算机不同，因此为了符合服务器的要求。我的其他JDBC参数如下所示：

useSSL=false&serverTimezone=America/Chicago

还要确保将数据库版本设置为 Mysql 8

Talend 7.1与MySQL Server 8.0（localhost）的连接失败
