Modifier and Type	Method	Description
org.springframework.http.ResponseEntity<Map<String,Object>>	handleConflict(IllegalStateException ex)
org.springframework.http.ResponseEntity<Map<String,Object>>	handleDataIntegrity(org.springframework.dao.DataIntegrityViolationException ex)	Maps a database constraint violation to a 409 rather than a 500.
org.springframework.http.ResponseEntity<Map<String,Object>>	handleGeneral(Exception ex)
org.springframework.http.ResponseEntity<Map<String,Object>>	handleMissingParam(org.springframework.web.bind.MissingServletRequestParameterException ex)	Maps a missing required query parameter (for example baselineRunId on the diff endpoint) to a 400 rather than letting it fall through to the generic 500 handler.
org.springframework.http.ResponseEntity<Map<String,Object>>	handleNotFound(IllegalArgumentException ex)
org.springframework.http.ResponseEntity<Map<String,Object>>	handleResponseStatus(org.springframework.web.server.ResponseStatusException ex)	Honors the status carried by a ResponseStatusException (for example a 400 raised by a controller for an unrecognized query-parameter value) instead of letting the generic handler collapse it to a 500.
org.springframework.http.ResponseEntity<Map<String,Object>>	handleUnreadableBody(org.springframework.http.converter.HttpMessageNotReadableException ex)	Maps an unparseable or type-mismatched request body (for example a malformed UUID) to a 400 rather than letting it fall through to the generic 500 handler.
org.springframework.http.ResponseEntity<Map<String,Object>>	handleValidation(org.springframework.web.bind.MethodArgumentNotValidException ex)	Maps bean-validation failures on @RequestBody payloads to a 400, surfacing the first field error message so the caller sees which constraint failed instead of an opaque 500.

Method Details

handleNotFound

@ExceptionHandler(java.lang.IllegalArgumentException.class)
public org.springframework.http.ResponseEntity<Map<String,Object>> handleNotFound(IllegalArgumentException ex)

handleConflict

@ExceptionHandler(java.lang.IllegalStateException.class)
public org.springframework.http.ResponseEntity<Map<String,Object>> handleConflict(IllegalStateException ex)

handleValidation

@ExceptionHandler(org.springframework.web.bind.MethodArgumentNotValidException.class)
public org.springframework.http.ResponseEntity<Map<String,Object>> handleValidation(org.springframework.web.bind.MethodArgumentNotValidException ex)

Maps bean-validation failures on @RequestBody payloads to a 400, surfacing the first field error message so the caller sees which constraint failed instead of an opaque 500.

handleMissingParam

@ExceptionHandler(org.springframework.web.bind.MissingServletRequestParameterException.class)
public org.springframework.http.ResponseEntity<Map<String,Object>> handleMissingParam(org.springframework.web.bind.MissingServletRequestParameterException ex)

Maps a missing required query parameter (for example baselineRunId on the diff endpoint) to a 400 rather than letting it fall through to the generic 500 handler.

handleUnreadableBody

@ExceptionHandler(org.springframework.http.converter.HttpMessageNotReadableException.class)
public org.springframework.http.ResponseEntity<Map<String,Object>> handleUnreadableBody(org.springframework.http.converter.HttpMessageNotReadableException ex)

Maps an unparseable or type-mismatched request body (for example a malformed UUID) to a 400 rather than letting it fall through to the generic 500 handler.

handleResponseStatus

@ExceptionHandler(org.springframework.web.server.ResponseStatusException.class)
public org.springframework.http.ResponseEntity<Map<String,Object>> handleResponseStatus(org.springframework.web.server.ResponseStatusException ex)

Honors the status carried by a ResponseStatusException (for example a 400 raised by a controller for an unrecognized query-parameter value) instead of letting the generic handler collapse it to a 500.

handleDataIntegrity

@ExceptionHandler(org.springframework.dao.DataIntegrityViolationException.class)
public org.springframework.http.ResponseEntity<Map<String,Object>> handleDataIntegrity(org.springframework.dao.DataIntegrityViolationException ex)

Maps a database constraint violation to a 409 rather than a 500. This covers the rare race where two concurrent writes both try to create a row guarded by a unique constraint (for example two simultaneous first-time annotations on the same item result); the loser gets a clean conflict it can retry instead of an opaque server error.

handleGeneral

@ExceptionHandler(java.lang.Exception.class)
public org.springframework.http.ResponseEntity<Map<String,Object>> handleGeneral(Exception ex)
