@Target(value=TYPE) @Retention(value=RUNTIME) @Documented @ControllerAdvice @ResponseBody public @interface RestControllerAdvice
@ControllerAdvice
and @ResponseBody
.
Types that carry this annotation are treated as controller advice where
@ExceptionHandler
methods assume
@ResponseBody
semantics by default.
NOTE: @RestControllerAdvice
is processed if an appropriate
HandlerMapping
-HandlerAdapter
pair is configured such as the
RequestMappingHandlerMapping
-RequestMappingHandlerAdapter
pair
which are the default in the MVC Java config and the MVC namespace.

annotations
Array of annotations.

Class<?>[] |
assignableTypes
Array of classes.

Class<?>[] |
basePackageClasses
Type-safe alternative to
value() for specifying the packages
to select Controllers to be assisted by the @ControllerAdvice
annotated class. |
String[] |
basePackages
Array of base packages.

value
Alias for the
basePackages() attribute. |
@AliasFor(value="basePackages") public abstract String[] value
basePackages()
attribute.
Allows for more concise annotation declarations e.g.:
@ControllerAdvice("org.my.pkg")
is equivalent to
@ControllerAdvice(basePackages="org.my.pkg")
.
basePackages()
@AliasFor(value="value") public abstract String[] basePackages
Controllers that belong to those base packages or sub-packages thereof
will be included, e.g.: @ControllerAdvice(basePackages="org.my.pkg")
or @ControllerAdvice(basePackages={"org.my.pkg", "org.my.other.pkg"})
.
value()
is an alias for this attribute, simply allowing for
more concise use of the annotation.
Also consider using basePackageClasses()
as a type-safe
alternative to String-based package names.
public abstract Class<?>[] basePackageClasses
value()
for specifying the packages
to select Controllers to be assisted by the @ControllerAdvice
annotated class.
Consider creating a special no-op marker class or interface in each package that serves no purpose other than being referenced by this attribute.
public abstract Class<?>[] assignableTypes
Controllers that are assignable to at least one of the given types
will be assisted by the @ControllerAdvice
annotated class.
public abstract Class<? extends Annotation>[] annotations
Controllers that are annotated with this/one of those annotation(s)
will be assisted by the @ControllerAdvice
annotated class.
Consider creating a special annotation or use a predefined one,
like @RestController
.
