Java 如何在SpringSOAPWeb服务中缓存JAXB上下文？

我们通过SpringInsight和NewRelic分析了我们的SpringSOAPWeb服务，超过60%的时间都用在Springjar上。我们猜测这与日志、jaxb上下文有关。我们正在公开soap ws

    <bean class="org.springframework.ws.soap.security.xwss.XwsSecurityInterceptor">
        <property name="policyConfiguration" value="/WEB-INF/securityPolicy.xml"/>
        <property name="callbackHandlers">
            <list> 
                <ref bean="callbackHandler"/>
            </list>
        </property>
    </bean>
</sws:interceptors>

<bean id="callbackHandler" class="org.springframework.ws.soap.security.xwss.callback.SimplePasswordValidationCallbackHandler">
    <property name="users">
        <props>
            </props>
    </property>
</bean>


<sws:static-wsdl id="employeeTransfer" location="/WEB-INF/wsdl/employeeTransfer.wsdl" />

我们还观察到，安全头占用了一些时间

    <bean class="org.springframework.ws.soap.security.xwss.XwsSecurityInterceptor">
        <property name="policyConfiguration" value="/WEB-INF/securityPolicy.xml"/>
        <property name="callbackHandlers">
            <list> 
                <ref bean="callbackHandler"/>
            </list>
        </property>
    </bean>
</sws:interceptors>

<bean id="callbackHandler" class="org.springframework.ws.soap.security.xwss.callback.SimplePasswordValidationCallbackHandler">
    <property name="users">
        <props>
            </props>
    </property>
</bean>


<sws:static-wsdl id="employeeTransfer" location="/WEB-INF/wsdl/employeeTransfer.wsdl" />

我们可以在SpringSOAPWeb服务中缓存JAXB上下文吗？或 还有其他提高SpringSOAPWeb服务性能的指标吗

    <bean class="org.springframework.ws.soap.security.xwss.XwsSecurityInterceptor">
        <property name="policyConfiguration" value="/WEB-INF/securityPolicy.xml"/>
        <property name="callbackHandlers">
            <list> 
                <ref bean="callbackHandler"/>
            </list>
        </property>
    </bean>
</sws:interceptors>

<bean id="callbackHandler" class="org.springframework.ws.soap.security.xwss.callback.SimplePasswordValidationCallbackHandler">
    <property name="users">
        <props>
            </props>
    </property>
</bean>


<sws:static-wsdl id="employeeTransfer" location="/WEB-INF/wsdl/employeeTransfer.wsdl" />

谢谢你的帮助

    <bean class="org.springframework.ws.soap.security.xwss.XwsSecurityInterceptor">

            <list> 
                <ref bean="callbackHandler"/>

实例化JAXBContext在执行时间方面是非常昂贵的操作。您应该定义一个具有单例作用域的Jaxb2Marshaller（在Spring3.0的OXM包中），以便在应用程序中只进行一次初始化。你能发布你的配置来看看你现在是怎么做的吗？“超过60%的时间都花在Springjar上了”，这并不能说明什么。它挂在哪个部件上，速度真的很慢，还是只有2ms的60%？你真的应该更具体，在哪些部分是缓慢的，你想优化。谢谢你的答复。总共需要7秒。但是，我们的java代码大约需要1.5秒。剩下的5.5秒用于spring框架的类。这是我们真正喜欢的配置文件或做一些事情来优化时间。我在您的配置中没有看到任何与Spring相关的bean。您是否在代码中手动初始化上下文？如果是，请发布相关的代码片段。
