通过Spring Boot属性设置事务隔离级别

Question

我有一个spring boot应用程序，我通过属性文件配置了大多数属性。但是，我在寻找是否有办法通过Spring引导属性设置TRANSACTION_ISOLATION_LEVEL。有人可以帮我这个。

我正在以下列方式初始化数据源bean：

class Program
{
    static void Main(string[] args)
    {
        try
        {
            using (var fi = new FileHandler())
            {
                //open the file
                fi.Open();

                //write to the file
                fi.Write();

                //excption occurs
                throw new Exception("Inside using block");

                fi.Close();
            }
        }
        catch (Exception e)
        {
            //now I only have the exception from the dispose but not the exception that occured in the using block itself
            //I know I could wrap the code inside the using in a try/catch itself, just asking if it is possible without 2 try/catches
        }
    }
}

public class FileHandler : IDisposable
{
    public void Dispose()
    {
        //Close the file
        //for some reason it fails with an exception
        throw new Exception("Inside dispose");
    }
}

有人可以帮助我了解如何通过属性或在数据源初始化期间指定TRANSACTION_ISOLATION_LEVEL。
