似乎调用XStream将对象转换为XML是正确的，但是忽略了@XStreamAlias注释。是否需要进一步配置才能使其正常工作？

解决了这个问题。带注释的类需要显式地标识给XStreamMarshaller

<property name="defaultViews">
    <list>
        <bean
        class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />

        <bean class="org.springframework.web.servlet.view.xml.MarshallingView">
            <constructor-arg>
                <bean class="org.springframework.oxm.xstream.XStreamMarshaller">
                    <property name="annotatedClasses">
                        <array>
                            <value>com.example.myapp.model.Person</value>
                        </array>
                    </property></bean>
            </constructor-arg>
        </bean>
    </list>
</property>

<property name="defaultViews">
    <list>
        <bean
        class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />

        <bean class="org.springframework.web.servlet.view.xml.MarshallingView">
            <constructor-arg>
                <bean class="org.springframework.oxm.xstream.XStreamMarshaller">
                    <property name="annotatedClasses">
                        <array>
                            <value>com.example.myapp.model.Person</value>
                        </array>
                    </property></bean>
            </constructor-arg>
        </bean>
    </list>
</property>

com.example.myapp.model.Person

我试图解决同样的问题（尽管是在Spring Boot项目中），并找到了另一个选择：

自动检测旋转

<property name="defaultViews">
    <list>
        <bean
        class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />

        <bean class="org.springframework.web.servlet.view.xml.MarshallingView">
            <constructor-arg>
                <bean class="org.springframework.oxm.xstream.XStreamMarshaller">
                    <property name="annotatedClasses">
                        <array>
                            <value>com.example.myapp.model.Person</value>
                        </array>
                    </property></bean>
            </constructor-arg>
        </bean>
    </list>
</property>

xstreamMarshaller.setAutodetectAnnotations(true);

，将上述行添加到Application.java
 根据XStream文档
<property name="defaultViews">
    <list>
        <bean
        class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />

        <bean class="org.springframework.web.servlet.view.xml.MarshallingView">
            <constructor-arg>
                <bean class="org.springframework.oxm.xstream.XStreamMarshaller">
                    <property name="annotatedClasses">
                        <array>
                            <value>com.example.myapp.model.Person</value>
                        </array>
                    </property></bean>
            </constructor-arg>
        </bean>
    </list>
</property>

您必须使用
xstream.processAnnotations（MyPOJO.class）
您不也希望元素是元素吗？同样，XStream（）.setAutodetectAnnotations（true）也可以工作（对于非Spring项目）。
<property name="defaultViews">
    <list>
        <bean
        class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />

        <bean class="org.springframework.web.servlet.view.xml.MarshallingView">
            <constructor-arg>
                <bean class="org.springframework.oxm.xstream.XStreamMarshaller">
                    <property name="annotatedClasses">
                        <array>
                            <value>com.example.myapp.model.Person</value>
                        </array>
                    </property></bean>
            </constructor-arg>
        </bean>
    </list>
</property>
