Usage

From source file:org.springframework.orm.jpa.EntityManagerFactoryUtils.java

/**
 * Convert the given runtime exception to an appropriate exception from the
 * {@code org.springframework.dao} hierarchy.
 * Return null if no translation is appropriate: any other exception may
 * have resulted from user code, and should not be translated.
 * <p>The most important cases like object not found or optimistic locking failure
 * are covered here. For more fine-granular conversion, JpaTransactionManager etc
 * support sophisticated translation of exceptions via a JpaDialect.
 * @param ex runtime exception that occurred
 * @return the corresponding DataAccessException instance,
 * or {@code null} if the exception should not be translated
 *//*from w ww.j a  v  a 2  s .c  o m*/
