CXF中使用dataBinding时遇到异常的解决办法

      不罗嗦，直接问题描述：我在使用java优先的方式写CXF服务时，因为用到了Map类型，所以想到使用CXF框架非默认的Aegis数据绑定方式。但是按照我自以为的方式配置的bean文件，在发布时遇到了异常：

异常摘要

nested exception is org.springframework.beans.NotWritablePropertyException:
Invalid property 'dataBinding' of bean class [org.apache.cxf.jaxws.spring.EndpointDefinitionParser$SpringEndpointImpl]: Bean property 'dataBinding' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

 

我原来的配置文件为：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws"
	xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

	<import resource="classpath:META-INF/cxf/cxf.xml" />
	<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
	<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

	
	<jaxws:endpoint id="LabsQuerying" implementor="rc.yuzone.services.LabsQueryImpl"
		address="/LabsQueryingService">
		<jaxws:dataBinding>
			<bean class="org.apache.cxf.aegis.databinding.AegisDatabinding" />
		</jaxws:dataBinding>
	</jaxws:endpoint>

</beans>

 

      后来谷歌了好久，终于在一张已经被删了的网页中（还好有快照功能）找到了灵感，我修改了配置文件，用了另一种绑定方式：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws"
	xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

	<import resource="classpath:META-INF/cxf/cxf.xml" />
	<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
	<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

	
	<jaxws:endpoint id="LabsQuerying" implementor="rc.yuzone.services.LabsQueryImpl"
		address="/LabsQueryingService">
		<jaxws:serviceFactory>
			<bean class="org.apache.cxf.jaxws.support.JaxWsServiceFactoryBean">
				<property name="dataBinding" ref="aegisBean" />
				<property name="serviceConfigurations">
					<list>
						<bean class="org.apache.cxf.jaxws.support.JaxWsServiceConfiguration" />
						<bean class="org.apache.cxf.aegis.databinding.AegisServiceConfiguration" />
						<bean class="org.apache.cxf.service.factory.DefaultServiceConfiguration" />
					</list>
				</property>
			</bean>
		</jaxws:serviceFactory>
	</jaxws:endpoint>
	<bean id="aegisBean" class="org.apache.cxf.aegis.databinding.AegisDatabinding"/>

</beans>

 

    如此修改以后再部署，Spring就不报错了，至少可以部署成功了。至于是否影响后续的开发，还有待时间检验；至于为什么，再研究吧。

至于原理， 我的blog 里面有一些关于CXF configuration的介绍

不知道用的CXF是什么版本， 通过 <jaxws:endpoint>来配置DataBinding 应该是没有问题的。
我在CXF2.2 上实验是没有问题。

这是具体的例子，包括了服务器端和客户端的配置。

<beans xmlns="http://www.springframework.org/schema/beans"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:jaxws="http://cxf.apache.org/jaxws"
      xmlns:cxf="http://cxf.apache.org/core"
      xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

    <!-- comment this bean to disable schema validation in the client -->

    <jaxws:client name="{http://apache.org/hello_world_soap_http}SoapPort"
        createdFromAPI="true">
        <jaxws:properties>
            <entry key="schema-validation-enabled" value="true" />
        </jaxws:properties>
        <jaxws:dataBinding>
        	<bean class="org.apache.cxf.xmlbeans.XmlBeansDataBinding"/>
        </jaxws:dataBinding>
    </jaxws:client>

    <jaxws:endpoint name="{http://apache.org/hello_world_soap_http}SoapPort"
        wsdlLocation="wsdl/hello_world.wsdl"
        createdFromAPI="true">
        <jaxws:properties>
            <entry key="schema-validation-enabled" value="true" />
        </jaxws:properties>
        <jaxws:dataBinding>
        	<bean class="org.apache.cxf.xmlbeans.XmlBeansDataBinding"/>
        </jaxws:dataBinding>
    </jaxws:endpoint>

</beans>
