Annotation

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.

Attribute Detail (all declarations; defined within this component only; 5/5)

index

Type:	xsd:string, predefined
Use:	optional

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.

<xsd:attribute name="index" type="xsd:string"/>

name

Type:	xsd:string, predefined
Use:	optional

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!

<xsd:attribute name="name" type="xsd:string"/>

ref

Type:	xsd:string, predefined
Use:	optional

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

XML Source (w/o annotations (1); see within schema source)

<xsd:attribute name="ref" type="xsd:string"/>

type

Type:	xsd:string, predefined
Use:	optional

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.

XML Source (w/o annotations (1); see within schema source)

<xsd:attribute name="type" type="xsd:string"/>

value

Type:	xsd:string, predefined
Use:	optional

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

XML Source (w/o annotations (1); see within schema source)

<xsd:attribute name="value" type="xsd:string"/>
