grails - 如何解决该异常；由ClassCastException引起:com.sun.proxy。$ Proxy31无法转换为javax.ws.rs.Produces

Question

我正在开发一个spring-data-neo4j项目，该项目是由Java开发的，但是为了提高生产率，我想更改为grails。我将以下applicationContext.xml内容复制到grails applicationContext.xml中:

    <!--Custom Configuration-->
    <context:annotation-config/>
    <context:spring-configured/>
<!--    <context:component-scan base-package="com.turingmac">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>-->

    <!-- Neo4j configuration (creates Neo4jTemplate) -->
    <neo4j:config graphDatabaseService="graphDatabaseService"/>
    <bean id="graphDatabaseService" class="org.springframework.data.neo4j.rest.SpringRestGraphDatabase" scope="singleton">
        <constructor-arg index="0" value="http://localhost:7474/db/data"/>
    </bean>

    <neo4j:repositories base-package="com.turingmac.repository"/>
    <tx:annotation-driven mode="proxy"/>

但是我得到了这个错误:

ERROR context.GrailsContextLoader - Error executing bootstraps: Error creating bean with name 'org.springframework.data.neo4j.config.Neo4jConfiguration#0': Cannot resolve reference to bean 'graphDatabaseService' while setting bean property 'graphDatabaseService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'graphDatabaseService' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.data.neo4j.rest.SpringRestGraphDatabase]: Constructor threw exception; nested exception is java.lang.ClassCastException: com.sun.proxy.$Proxy31 cannot be cast to javax.ws.rs.Produces Message: Error creating bean with name 'org.springframework.data.neo4j.config.Neo4jConfiguration#0': Cannot resolve reference to bean 'graphDatabaseService' while setting bean property 'graphDatabaseService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'graphDatabaseService' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.data.neo4j.rest.SpringRestGraphDatabase]: Constructor threw exception; nested exception is java.lang.ClassCastException: com.sun.proxy.$Proxy31 cannot be cast to javax.ws.rs.Produces Caused by BeanInstantiationException: Could not instantiate bean class [org.springframework.data.neo4j.rest.SpringRestGraphDatabase]: Constructor threw exception; nested exception is java.lang.ClassCastException: com.sun.proxy.$Proxy31 cannot be cast to javax.ws.rs.Produces Caused by ClassCastException: com.sun.proxy.$Proxy31 cannot be cast to javax.ws.rs.Produces

我尝试了很多方法，例如升级springframework版本，添加额外的jar，这是行不通的。
