how to convert IllegalAccessException to DataAccessException

I use class "org.apache.commons.beanutils.BeanUtils" in a dao method.

it throws java.lang.IllegalAccessException and
java.lang.reflect.InvocationTargetException.

I want to convert the exceptions to org.springframework.dao.DataAccessException;

which implements of DataAccessException seemly for instead?

DataAccessExceptions are converted from SQLExceptions using a SQLExceptionTranslator which is a property of the JdbcTemplate class. It doesn't appear there is a way to capture non-SQLExceptions and convert them to another exception type.

The only way I think of fixing this is to implement a subclass of BeanUtils to intercept the desired exceptiosn and throw DataAccessExceptions.

You can simply catch the exception and throw an appropriate subclass of DataAccessException (probably a subclass of one of the existing classes lower down).
