@Target(TYPE)
@Retention(RUNTIME)
@Documented
@ControllerAdvice
@ResponseBody
public @interface RestControllerAdvice
```
A convenience annotation that is itself annotated with @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.

```
@AliasFor(annotation=ControllerAdvice.class)
String[] value
```
    Alias for the basePackages() attribute.
    Allows for more concise annotation declarations — for example, @RestControllerAdvice("org.my.pkg") is equivalent to @RestControllerAdvice(basePackages = "org.my.pkg").
    另请参阅:
    basePackages()
    默认值:
    {}
- - basePackages
```
@AliasFor(annotation=ControllerAdvice.class)
String[] basePackages
```
    Array of base packages.
    Controllers that belong to those base packages or sub-packages thereof will be included — for example, @RestControllerAdvice(basePackages = "org.my.pkg") or @RestControllerAdvice(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.
    默认值:
    {}
- - basePackageClasses
```
@AliasFor(annotation=ControllerAdvice.class)
Class<?>[] basePackageClasses
```
    Type-safe alternative to basePackages() for specifying the packages in which to select controllers to be advised by the @RestControllerAdvice 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.
    默认值:
    {}
- - assignableTypes
```
@AliasFor(annotation=ControllerAdvice.class)
Class<?>[] assignableTypes
```
    Array of classes.
    Controllers that are assignable to at least one of the given types will be advised by the @RestControllerAdvice annotated class.
    默认值:
    {}
- - annotations
```
@AliasFor(annotation=ControllerAdvice.class)
Class<? extends Annotation>[] annotations
```
    Array of annotations.
    Controllers that are annotated with at least one of the supplied annotation types will be advised by the @RestControllerAdvice annotated class.
    Consider creating a custom composed annotation or use a predefined one, like @RestController.
    默认值:
    {}
