Insert custom annotation in java 'field' using annotate plugin + JAXB (upon xsd -> java)
提问by Hari
Use case:
用例：
Wanna insert custom annotation to fields in java class generated by JAXB
想在 JAXB 生成的 java 类中的字段中插入自定义注释
Problem:
问题：
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].
使用 Annotate 插件 + JAXB [1]，能够成功插入自定义注释，但它们是在 getter 方法而不是字段中插入的。Morphia (mongo DB) 注释（我实际上想要插入）但是只能注释 java 字段 [2]。
My test xsd:
我的测试 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:
我的测试绑定 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:
我生成的java片段：
@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.
如您所见，我想注释“bar”字段。请指教。如果需要，请询问更多。
[1] Generate @Indexed annotation using Jaxb or HyperJaxb
[2] For sample see @Id annotation of Morphia
[1]使用 Jaxb 或 HyperJaxb 生成 @Indexed 注释
[2] 示例参见 Morphia 的 @Id 注释

Ok, you figured it out yourself. Use <annox:annotate target="field">to annotate a field. Other options are:
好吧，你自己想出来了。使用<annox:annotate target="field">注释字段。其他选项是：
- setter
- setter-parameter
- getter
- field
- class
- 二传手
- 设置参数
- 吸气剂
- 场地
- 班级
See the documentation.
请参阅文档。

Just one more thing: you need to put the fieldattribute to the outer <annox:annotate>tag:
还有一件事：您需要将field属性放在外部<annox:annotate>标签中：
<annox:annotate target="field">
<annox:annotate annox:class="java.lang.SuppressWarnings"/>
</annox:annotate>
Putting it to the same tag as the annox:classattribute resides might not work. That happend to me.
将它放在与annox:class属性所在的标签相同的标签中可能不起作用。那发生在我身上。
