CXF XJC Default Value Plugin
The CXF XJC Default Value Plugin provides and XJC plugin that updates the generated beans to return the default value defined in the schema for fields that are unset in the instance.
For example, if the schema contains:
| Code Block |
|---|
|
<xs:complexType name="pageColor">
<xs:sequence>
<xs:element name="background" type="xs:string" default="red"/>
<xs:element name="foreground" type="xs:string" default="blue"/>
</xs:sequence>
</xs:complexType>
|
it would generate getter methods like:
| Code Block |
|---|
|
public String getBackground() {
if (null == background) {
return "red";
}
return background;
}
public String getForeground() {
if (null == foreground) {
return "blue";
}
return foreground;
}
|
Normally, XJC would just generate code like:
| Code Block |
|---|
|
public String getBackground() {
return background;
}
public String getForeground() {
return foreground;
}
|
so code that works with the beans need to take the possible null return into account.
To use with Maven
