java - jaxb 解码器将值读取为 0

Question

JAXBContext jaxbContext = JAXBContext.newInstance(BatchwisePricingJob.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();

StringReader reader = new StringReader(batchprice.toString());

BatchwisePricingJob batch = (BatchwisePricingJob) jaxbUnmarshaller.unmarshal(reader);
ArrayList<Price> pricingOfProduct = batch.getPricingOfProduct();

int i = 0;
for (Price price : pricingOfProduct) {
    i++;
    System.out.println("customer id:" + i + " " + price.getCustomerId());
    System.out.println("material id:" + i + " " + price.getMaterialId());
}

还为 getter/setter 提供了 @XmlElement 注释，但随后它抛出了 Illegalannotationexceptions

Class has two properties of the same name "customerId"

如果 XML 文档与您的映射不匹配，则解码的值将为 null。最简单的方法是填充对象模型，然后将其编码以查看与当前映射相对应的 XML。如果所需名称与默认名称不同，您可以使用 @XmlElement 和 @XmlAttribute 指定要映射到的名称。

如果您映射该字段及其相应的属性，您将看到以下异常。以下文章将为您提供帮助:http://blog.bdoughan.com/2011/06/using-jaxbs-xmlaccessortype-to.html
