TypeConversion Annotation

This annotation is used for class and application wide conversion rules.

Class wide conversion:
The conversion rules will be assembled in a file called XXXAction-conversion.properties within the same package as the related action class. Set type to: type = ConversionType.CLASS

Allication wide conversion:
The conversion rules will be assembled within the xwork-conversion.properties file within the classpath root. Set type to: type = ConversionType.APPLICATION

Usage

The TypeConversion annotation can be applied at property and method level.

Parameters

Parameter	Required	Default	Description
key	no	The annotated property/key name	The optional property name mostly used within TYPE level annotations.
type	no	ConversionType.CLASS	Enum value of ConversionType. Determines whether the conversion should be applied at application or class level.
rule	no	ConversionRule.PROPERTY	Enum value of ConversionRule. The ConversionRule can be a property, a Collection or a Map.
converter	either this or value		The class name of the TypeConverter to be used as converter.
value	either converter or this		The value to set for ConversionRule.KEY_PROPERTY.

Examples

@Conversion()
public class ConversionAction implements Action {

  private String convertInt;

  private String convertDouble;
  private List users = null;

  private HashMap keyValues = null;

  @TypeConversion(type = ConversionType.APPLICATION, converter = "com.opensymphony.xwork2.util.XWorkBasicConverter")
  public void setConvertInt( String convertInt ) {
      this.convertInt = convertInt;
  }

  @TypeConversion(converter = "com.opensymphony.xwork2.util.XWorkBasicConverter")
  public void setConvertDouble( String convertDouble ) {
      this.convertDouble = convertDouble;
  }

  @TypeConversion(rule = ConversionRule.COLLECTION, converter = "java.util.String")
  public void setUsers( List users ) {
      this.users = users;
  }

  @TypeConversion(rule = ConversionRule.MAP, converter = "java.math.BigInteger")
  public void setKeyValues( HashMap keyValues ) {
      this.keyValues = keyValues;
  }
