如何为 com.mysql.cj.jdbc.MysqlXADataSource 设置类路径

Question

我想在 glassfish 应用程序服务器中部署名为“banksmart”的应用程序。

此步骤是为 banksmart 部署的数据库连接完成的。

当我从这里 ping glassfish 时出现以下错误：

Ping Connection Pool failed for banksmart. Class name is wrong or classpath is not set for : com.mysql.cj.jdbc.MysqlXADataSource Please check the server.log for more details.

这是 JDBC 资源设置：

这里是 JDBC 连接池设置：

这是 server.log 日志文件。

如何解决这个错误？

Answer 1

两个问题。

jarfile 放错地方了。应该在 /lib 而不是 lib/ext.

你拿错罐子了。您需要 mysql-connector-j-8.0.33.jar 或可能是旧版本。 sqljdbc 适用于 ms sqlserver。

其他看起来不对劲的是您的资源类型是

XADataSource

，但您选择了一个非 XA 驱动程序类。他们需要匹配。我怀疑你想要

com.mysql.cj.jdbc.MysqlXADataSource

Answer 2

我把提到的所有内容都放在另一个答案中，所以我建议您遵循那个答案。

最重要的事情是：

1. 将所有这些

   .jar

   文件包含在两个存在的

   lib

   目录中。
2. 在JDBC连接池设置中添加一个新的属性：

   "useSSL"

   并将其值设置为

   false

   .

执行此操作后，您会收到一些明显的错误消息，但这些错误消息应该不难修复。
