我正在使用JAXB 2.0 JDK 6将XML实例解组到POJO中。解组对象时,JAXB不调用setter
为了添加一些自定义验证,我将验证调用插入到属性的setter中,但尽管它是私有的,但似乎unmarshaller不会调用setter,而是直接修改私有字段。
对于我而言,每次取消编组调用都会针对此特定字段进行自定义验证,这一点至关重要。
我该怎么办?
代码:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "LegalParams", propOrder = {
"value"
})
public class LegalParams {
private static final Logger LOG = Logger.getLogger(LegalParams.class);
@XmlTransient
private LegalParamsValidator legalParamValidator;
public LegalParams() {
try {
WebApplicationContext webApplicationContext = ContextLoader.getCurrentWebApplicationContext();
LegalParamsFactory legalParamsFactory = (LegalParamsFactory) webApplicationContext.getBean("legalParamsFactory");
HttpSession httpSession = SessionHolder.getInstance().get();
legalParamValidator = legalParamsFactory.newLegalParamsValidator(httpSession);
}
catch (LegalParamsException lpe) {
LOG.warn("Validator related error occurred while attempting to construct a new instance of LegalParams");
throw new IllegalStateException("LegalParams creation failure", lpe);
}
catch (Exception e) {
LOG.warn("Spring related error occurred while attempting to construct a new instance of LegalParams");
throw new IllegalStateException("LegalParams creation failure", e);
}
}
@XmlValue
private String value;
/**
* Gets the value of the value property.
*
* @return
* possible object is
* {@link String }
*
*/
public String getValue() {
return value;
}
/**
* Sets the value of the value property.
*
* @param value
* allowed object is
* {@link String }
* @throws TestCaseValidationException
*
*/
public void setValue(String value) throws TestCaseValidationException {
legalParamValidator.assertValid(value);
this.value = value;
}
}
谢谢你的诀窍:) – Yaneeve 2010-04-22 11:43:59
