spring jdbc模板返回空结果

Question

I have the following code

resultList = daoResources.jdbcTemplate.query(sql, selectParams, new BeanPropertyRowMapper(resultClass));

SQL when run with the selectParams against database, I get result. The selecting fields name of the sql matches with the fields in the resultClass too. But for above code, I get an empty resultList.

Where could be the problem?

Debugging is your friend in this scenario. I suggest you enable debug logs for jdbc template to see what sql's and bind parameters are sent to database. Below is from the 3.0.x reference doc

All SQL issued by this class is logged at the DEBUG level under the category corresponding to the fully qualified class name of the template instance (typically JdbcTemplate, but it may be different if you are using a custom subclass of the JdbcTemplate class).
