BigDecimal error reporting series of daily BUG writing

Following the previous blog post, I was still processing a large amount of table data. After
solving the data type problem, I still reported an error, which was puzzled. After
careful inspection, I found the problem: When
testing the data type, only notice that the two fields are BigDecimal but ignore the difference in the package. .
After modifying the BigDecimal of the same package, test again to confirm: the
code passed smoothly... (I am really a lot of low-level errors that can be avoided with a little care)
