Insert custom annotation in java 'field' using annotate plugin + JAXB (upon xsd -> java)
Solution 1
Ok, you figured it out yourself. Use <annox:annotate target="field">
to annotate a field. Other options are:
- setter
- setter-parameter
- getter
- field
- class
See the documentation.
Solution 2
Just one more thing: you need to put the field
attribute to the outer <annox:annotate>
tag:
<annox:annotate target="field">
<annox:annotate annox:class="java.lang.SuppressWarnings"/>
</annox:annotate>
Putting it to the same tag as the annox:class
attribute resides might not work. That happend to me.

Use case:
Wanna insert custom annotation to fields in java class generated by JAXB
Problem:
Using Annotate plugin + JAXB [1], am able to successfully insert custom annotations but they are getting inserted at getter method rather than field. Morphia (mongo DB) annotations (that i actually want to insert) however can annotate only java fields [2].
My test xsd:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.1" xmlns:annox="http://annox.dev.java.net" jaxb:extensionBindingPrefixes="annox"> <xsd:element name="hoo" type="External" /> <xsd:complexType name="External"> <xsd:sequence> <xsd:element name="bar" type="xsd:string" /> <xsd:element name="hoobar" type="xsd:string" /> </xsd:sequence> </xsd:complexType> </xsd:schema>
My test binding xjb:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <jaxb:bindings version="2.1" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:annox="http://annox.dev.java.net" jaxb:extensionBindingPrefixes="annox"> <jaxb:bindings schemaLocation="external.xsd" node="/xs:schema"> <jaxb:bindings node="xs:complexType[@name='External']/xs:sequence/xs:element[@name='bar']"> <annox:annotate> <annox:annotate annox:class="java.lang.SuppressWarnings" impl="com.acme.foo.MyFieldBridge"> </annox:annotate> </annox:annotate> </jaxb:bindings>
My generated java snippet:
@XmlElement(required = true) protected String bar; @XmlElement(required = true) protected String hoobar; /** * Gets the value of the bar property. * * @return * possible object is * {@link String } * */ @SuppressWarnings({ }) public String getBar() { return bar; }
As you can see, i want to annotate "bar" field. Please advise. Ask for more if needed.
[1] Generate @Indexed annotation using Jaxb or HyperJaxb
[2] For sample see @Id annotation of Morphia -
