我的班级结构如下：

@XmlRootElement(name = "storage")
@XmlType(propOrder = {
        "entries"
})
@XmlAccessorType(XmlAccessType.FIELD)
public class A {
    @XmlElement(name = "configuration")
    private Set<ClassB> entries;
    ...
}

@XmlRootElement(name = "configuration")
@XmlType(propOrder = {
        "name",
        "entries"
})
@XmlAccessorType(XmlAccessType.FIELD)
public class B {
    private String name;
    @XmlElement(name = "configurationEntry")
    private Set<ClassC> entries;
    ...
}

@XmlRootElement(name = "configurationEntry")
@XmlType(propOrder = {
        "property1",
        "property2",
        "property3"
})
@XmlAccessorType(XmlAccessType.FIELD)
public class C {
    private String property1;
    private String property2;
    private String property3;
    ...
}

当我使用 Jersey 制作 XML 时，当我尝试访问根容器（A 类）时得到以下输出。我不知道为什么有标签而不是标签。

<Bes>
    <configuration>
        <name>Name1</name>
        <configurationEntry>
            <property1>...</property1>
            <property2>...</property2>
            <property3>...</property2>
        </configurationEntry>
        <configurationEntry>
            <property1>...</property1>
            <property2>...</property2>
            <property3>...</property2>
        </configurationEntry>
    </configuration>
    <configuration>
        <name>Name2</name>
        <configurationEntry>
            <property1>...</property1>
            <property2>...</property2>
            <property3>...</property2>
        </configurationEntry>
        <configurationEntry>
            <property1>...</property1>
            <property2>..</property2>
            <property3>...</property2>
        </configurationEntry>
    </configuration>
</Bes>

当我尝试访问 ClassB 容器之一时，我得到以下信息。（与以前类似的问题），而不是我得到并且没有包含标签。

<Aes>
    <configurationEntry>
        <property1>...</property1>
        <property2>...</property2>
        <property3>...</property2>
    </configurationEntry>
    <configurationEntry>
        <property1>...</property1>
        <property2>...</property2>
        <property3>...</property2>
    </configurationEntry>
<Aes>

唯一能按预期工作的是最低级别的 C 类

<configurationEntry>
    <property1>...</property1>
    <property2>...</property2>
    <property3>...</property2>
</configurationEntry>

为了清楚起见，我想要的输出如下：

访问存储（A 类）容器时：

<storage>
    <configuration>
        <name>Name1</name>
        <entries>
            <configurationEntry>
                <property1>...</property1>
                <property2>...</property2>
                <property3>...</property2>
            </configurationEntry>
            <configurationEntry>
                <property1>...</property1>
                <property2>...</property2>
                <property3>...</property2>
            </configurationEntry>
        </entries>
    </configuration>
    <configuration>
        <name>Name2</name>
        <entries>
            <configurationEntry>
                <property1>...</property1>
                <property2>...</property2>
                <property3>...</property2>
            </configurationEntry>
            <configurationEntry>
                <property1>...</property1>
                <property2>..</property2>
                <property3>...</property2>
            </configurationEntry>
        </entries>
    </configuration>
</storage>

访问二级容器 B 类时，我想要以下内容：

<configuration>
    <name>Name1</name>
    <entries>
        <configurationEntry>
            <property1>...</property1>
            <property2>...</property2>
            <property3>...</property2>
        </configurationEntry>
        <configurationEntry>
            <property1>...</property1>
            <property2>...</property2>
            <property3>...</property2>
        </configurationEntry>
    </entries>
</configuration>

C类是可以的：

<configurationEntry>
    <property1>...</property1>
    <property2>...</property2>
    <property3>...</property2>
</configurationEntry>

因为我看到标签<Bes>并且<Aes>在 A 类和 B 类中。我觉得你已经定义了根元素。我的意思是 A 类和 B 类是另一个类的子集。检查这个，因为 xml 只能有一个根元素。如果是这样，那么类 A 和 B 中的根元素是无效的。我没有看到类中定义的 xml 有任何问题。欲了解更多信息，请访问http://java.dzone.com/articles/jaxb-and-root-elements

没关系，我是个白痴。-.-'

在我的客户端代码中，出于某种原因，我分别检索Set<B>andSet<C>而不是Aand B。
