DuplicateKeyException (Spring Framework 4.3.30.RELEASE API)

java.lang.Object
- java.lang.Throwable
- - java.lang.Exception
  - - java.lang.RuntimeException
    - - org.springframework.core.NestedRuntimeException
      - org.springframework.dao.DataAccessException
        org.springframework.dao.NonTransientDataAccessException
        org.springframework.dao.DataIntegrityViolationException
        org.springframework.dao.DuplicateKeyException

所有已实现的接口:
Serializable
```
public class DuplicateKeyException
extends DataIntegrityViolationException
```
Exception thrown when an attempt to insert or update data results in violation of an primary key or unique constraint. Note that this is not necessarily a purely relational concept; unique primary keys are required by most database types.
