Development: Exception collection software caused connection Abort:recv failed

Recently with Ibatis more, in the middle also encountered a lot of small problems, but also tangled my special long. Recorded:

One:java.sql.SQLException:Io exception: Software caused connection Abort:recv failed

This problem for a long time, because most of the data query is not a problem, when the search for a specific data on the occurrence of this, probably means that the query, the connection is closed

Then go to the database to see the data, found that the data table and entity are different, the data table more than one column line, the column most of the data is empty. So most of the queries are okay,

This error occurs when you find that a line is not empty and does not correspond to the entity attribute.

Workaround:

1. Empty all the contents of this field in the data table

2. Kill This field

3. Add this attribute to the entity
