I use Mybatis-plus to insert data,the result of insertion is 1 means success.But the oracle database have not this record randomly.I use the baseMapper of Mybatis-plus and dont use extra sql.In the same method,there is another insert operation can insert data successfully.the @Mapper is used.
What are some of the areas where there may be problems?

I print the result of insertion is 1,I hope the data can be insert Stably
