异常：
{org.springframework.dao.TransientDataAccessResourceException: PreparedStatementCallback; SQL [略。。。]; Value '0000-00-00 00:00:00' can not be represented as java.sql.Timestamp; nested exception is java.sql.SQLException: Value '0000-00-00 00:00:00' can not be represented as java.sql.Timestamp"}

When using MySql, the field type in the database is timestamp, the default is 0000-00-00, an exception will occur: java.sql.SQLException: Value '0000-00-00 ' can not be represented as java.sql.Timestamp
Solution:
Add the zeroDateTimeBehavior parameter to the jdbc url:
datasource.url=jdbc:mysql://localhost:3306/testdb?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&transformedBitIsBoolean=true
zeroDateTimeBehavior=round is to specify how the default value of the DateTime field in MySql is queried; the default is to throw an exception,
For a record with a value of 0000-00-00 00:00:00 (the default value), the following two configurations will return different results:
zeroDateTimeBehavior=round 0001-01-01 00:00:00.0
zeroDateTimeBehavior = convertToNull null

Just guessing, because you haven't shown anything but a stack trace, but I'd say that you're creating a PreparedStatement with the query
select id from employeerole where username = kiran and pin is NULL
and you're later invoking setString(1, someString) on the PreparedStatement (by means of StatementCreatorUtils#setParameterValue())
To use setString with a PreparedStatement you'd have to have a query with parameters (? ) on it. In that query you don't have any parameters but you're also setting a value for parameter #1.
For further reference on PreparedStatements, I'd recommend taking a read, at least, at this tutorial: Using Prepared Statements
Just to add, if the username column is a character-typed column, you'll have to quote the String kiran in your sql query.
Note that PreparedStatements handle that for you when using a parameterized query. Aside from that advantage it's the most basic protection against SQL Injection, because it also escapes parameters as needed.

JDBC报错:Value '0000-00-00' can not be represented as java.sql.Date
When I read the date type from sql, the data is 0000-00-00, and the above error is reported. This is because "0000-00-00" exists as a special value in mysql, but in Java, java.sql.Date will be regarded as an illegal value, and the JVM considers it to be malformed.
Solution:
Add the zeroDateTimeBehavior parameter to the url of jdbc: Reference: http://zhaohe162.blog.163.com/blog/static/3821679720110261248540/
datasource.url=jdbc:mysql://localhost:3306/pe?useUnicode=true&characterEncoding=gbk&zeroDateTimeBehavior=convertToNull
For records whose value is 0000-00-00 00:00:00 (the default value), different results will be returned depending on the configuration:
Do not configure: return an exception by default
zeroDateTimeBehavior=round 0001-01-01 00:00:00.0
zeroDateTimeBehavior = convertToNull null
