将 java 从 1.8.0_77 更新到 1.8.0_121 后，JAXB 不会解组

问题描述

昨天我更新了标题中发布的java，现在JAXB不再解析xml了.所有对象都只是空，似乎没有设置.

Yesterday I updated java like posted in the title, now JAXB doesn't parse xml anymore. All objects are simply null, nothing seems to be set.

鉴于此 POJO - ListMatchingProductsResponse

Given this POJO - ListMatchingProductsResponse

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "ListMatchingProductsResponse", propOrder = {
        "listMatchingProductsResult",
        "responseMetadata"
})
@XmlRootElement(name = "ListMatchingProductsResponse")
public class ListMatchingProductsResponse {
    @XmlElement(name = "ListMatchingProductsResult")
    private ListMatchingProductsResult listMatchingProductsResult;
    @XmlElement(name = "ResponseMetadata")
    private ResponseMetadata responseMetadata;
    @XmlAttribute(name = "xmlns")
    private String xmlns;

    public String getXmlns() {
        return xmlns;
    }

    public void setXmlns(String xmlns) {
        this.xmlns = xmlns;
    }


    /**
     * Get the value of ListMatchingProductsResult.
     *
     * @return The value of ListMatchingProductsResult.
     */
    public ListMatchingProductsResult getListMatchingProductsResult() {
        return listMatchingProductsResult;
    }

    /**
     * Set the value of ListMatchingProductsResult.
     *
     * @param listMatchingProductsResult The new value to set.
     */
    public void setListMatchingProductsResult(ListMatchingProductsResult listMatchingProductsResult) {
        this.listMatchingProductsResult = listMatchingProductsResult;
    }

    /**
     * Get the value of ResponseMetadata.
     *
     * @return The value of ResponseMetadata.
     */
    public ResponseMetadata getResponseMetadata() {
        return responseMetadata;
    }

    /**
     * Set the value of ResponseMetadata.
     *
     * @param responseMetadata The new value to set.
     */
    public void setResponseMetadata(ResponseMetadata responseMetadata) {
        this.responseMetadata = responseMetadata;
    }
}

还有 ListMatchingProductsResult

And the ListMatchingProductsResult

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name="ListMatchingProductsResult", propOrder={
    "products"
})
@XmlRootElement(name = "ListMatchingProductsResult")
public class ListMatchingProductsResult {

    @XmlElement(name="Products")
    private ProductList products;

    /**
     * Get the value of Products.
     *
     * @return The value of Products.
     */
    public ProductList getProducts() {
        return products;
    }

    /**
     * Set the value of Products.
     *
     * @param products
     *            The new value to set.
     */
    public void setProducts(ProductList products) {
        this.products = products;
    }

    /**
     * Check to see if Products is set.
     *
     * @return true if Products is set.
     */
    public boolean isSetProducts() {
        return products != null;
    }


    @Override
    public String toString() {
        return MoreObjects.toStringHelper(this)
                .add("products", products)
                .toString();
    }
}

我用它来解组:

String s = getResult();
// s is the expected xml string
ListMatchingProductsResponse m = JAXB.unmarshal(new StringReader(s), ListMatchingProductsResponse.class);
log.info(m); // ListMatchingProductsResponse@7164e54
log.info(m.getListMatchingProductsResult()); // null

我有点不知所措，因为我没有看到任何原因，也没有在更新日志中找到有关 JAXB 的任何更改.

I'm a bit lost as I don't see any kind of reason for this, nor did I find any changes regarding JAXB in the changelog.

我在这里做错了什么?

到目前为止，以下答案并没有解决我的问题

The following answers didn't solve my issue so far

JAXB 配置因集合从 JDK 1.7 升级到 JDK 1.8 u05 而被破坏

解组 jaxB 不起作用，对象为空

使用 JAXB 解组不起作用

更新

我现在已将以下依赖项包含到我的项目中

I now have included the following dependency to my project

group: 'org.jvnet.jaxb2.maven2', name: 'maven-jaxb2-plugin', version: '0.13.1'

它再次工作.这么新的问题——为什么会这样?121 java 版本中是否缺少某些内容/错误?

and it works again. So new question - why is that? Is there something missing / a bug in the 121 java release?
