3 Analysis of the problem

It is obviously because there is no permission to access the MySQL database , causing access to be denied.

Open the code and see that it is indeed the case. The account and password for accessing the database are not provided in the code

ds.setClassName("bitronix.tm.resource.jdbc.lrc.LrcXADataSource");
          ds.getDriverProperties().put(
              "url",
              connectionURL != null ? connectionURL
                  : "jdbc:mysql://localhost:3306/hibernate?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull"
          );
          Properties dp=ds.getDriverProperties();
          dp.put("driverClassName", "com.mysql.jdbc.Driver");
          ds.setDriverProperties(dp);

##4 Solution Question
