spring mvc 使用XStream返回xml下划线问题5

小弟今天用Spring mvc XStream 返回xml数据，发现给返回的pojo对象修改别名（改成有别名中有"_"）的问题：

返回的POJO对象：

返回到前端的XML数据：

按道理graphicId应该是以grapic_id作为名称，但是实际返回的是grapic__id两个下划线，这个问题如何解决，大家帮忙。感谢

Why do field names suddenly have double underscores in the generated XML?

XStream maps Java class names and field names to XML tags or attributes. Unfortunately this mapping cannot be 1:1, since some characters used for identifiers in Java are invalid in XML names. Therefore XStream uses an XmlFriendlyNameCoder to replace these characters with a replacement. By default this NameCoder uses an underscore as escape character and has therefore to escape the underscore itself also. You may provide a different configured instance of the XmlFriendlyNameCoder or a complete different implementation like the NoNameCoder to prevent name coding at all. However it is your responsibility then to ensure, that the resulting names are valid for XML.

1、1.4及以后
<bean id="marshaller" class="org.springframework.oxm.xstream.AnnotationXStreamMarshaller">
        <property name="streamDriver">
            <bean class="com.thoughtworks.xstream.io.xml.StaxDriver">
                <constructor-arg>
                    <bean class="com.thoughtworks.xstream.io.naming.NoNameCoder()">
                    </bean>
                </constructor-arg>
            </bean>
        </property>
    </bean>

2、1.4之前

    <bean id="marshaller" class="org.springframework.oxm.xstream.AnnotationXStreamMarshaller">
        <property name="streamDriver">
            <bean class="com.thoughtworks.xstream.io.xml.XppDriver">
                <constructor-arg>
                    <bean class="com.thoughtworks.xstream.io.xml.XmlFriendlyReplacer">
                        <constructor-arg index="0" value="_-"/>
                        <constructor-arg index="1" value="_"/>
                    </bean>
                </constructor-arg>
            </bean>
        </property>
    </bean>

3、注册到spring mvc
<mvc:annotation-driven>
<mvc:message-converters>
      <bean class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
<property name="marshaller" ref="marshaller" />
<property name="unmarshaller" ref="marshaller" />
</bean>
</mvc:message-converters>
</mvc:annotation-driven>

因为XStream用下划线当转义符。
你恐怕得自定义个NameCoder
