element constructor-arg

Documentation

				
	Bean definitions can specify zero or more constructor arguments.
	This is an alternative to "autowire constructor".
	Arguments correspond to either a specific index of the constructor
	argument list or are supposed to be matched generically by type.

	Note: A single generic argument value will just be used once, rather
	than potentially matched multiple times (as of Spring 1.1).

	constructor-arg elements are also used in conjunction with the
	factory-method element to construct beans using static or instance
	factory methods.

This component is not nillable.

Model

<constructor-arg
  index = xsd:string
  name = xsd:string
  ref = xsd:string
  type = xsd:string
  value = xsd:string>
(description?, (bean | ref | idref | value | null | array | list | set | map | props | (any element from any other namespace))? )
</constructor-arg>

index

The exact index of the argument in the constructor argument list. Only needed to avoid ambiguities, e.g. in case of 2 arguments of the exact same type.

Type:

xsd:string

Use:

optional

Form:

unqualified

name

The exact name of the argument in the constructor argument list. Only needed to avoid ambiguities, e.g. in case of 2 arguments of the exact same type. Note: This requires debug symbols to be stored in the class file in order to introspect argument names!

Type:

xsd:string

Use:

optional

Form:

unqualified

ref

A short-cut alternative to a nested "<ref bean='...'/>" element.

Type:

xsd:string

Use:

optional

Form:

unqualified

type

The exact type of the constructor argument. Only needed to avoid ambiguities, e.g. in case of 2 single argument constructors that can both be converted from a String.

Type:

xsd:string

Use:

optional

Form:

unqualified

value

A short-cut alternative to a nested "<value>...<value/>" element.

Type:

xsd:string

Use:

optional

Form:

unqualified
