Access the database through ibaties and return the list to Javalist. the mysql console queries the Java code for 0.004 seconds for about 1 minute. In some cases, you can use the mysql management tool to query millions of data. in simple SQL statements, the actual data time is 4 minutes, and the query time returned by the system is 0.002 seconds.
