@AliasFor(value="name")
public abstract String value

Alias for name().

默认值:

""

name

@AliasFor(value="value")
public abstract String name

The name of the request parameter to bind to.

默认值:

required

public abstract boolean required

Whether the parameter is required.

Defaults to true, leading to an exception being thrown if the parameter is missing in the request. Switch this to false if you prefer a null value if the parameter is not present in the request.

Alternatively, provide a defaultValue(), which implicitly sets this flag to false.

true

defaultValue

public abstract String defaultValue

The default value to use as a fallback when the request parameter is not provided or has an empty value.

Supplying a default value implicitly sets required() to false.

默认值:

"\n\t\t\n\t\t\n\ue000\ue001\ue002\n\t\t\t\t\n"
