我想部署一个生成JSON的jersey restful webservice。但我得到以下错误

14:08:26,743错误[org.jboss.MSC.service.fail](MSC服务线程1-9)MSC00001:无法启动服务jboss.deployment.unit.“rssample.war”.POST_MODULE:org.jboss.MSC.service.startService jboss.deployment.unit.“rssample.war”.POST_MODULE:org.jboss.as.server.deployment.deployment.deployment.deployment.deployment.deployment.start(ed:org.jboss.as.server.deployment.DeploymentUnitProcessingException:JBAS011232:只允许一个JAX-RS应用程序类。org.glassfish.jersey.server.resourceconfig org.glassfish.jersey.server.resourceconfig$wrappingresourceconfig org.jboss.as.jaxrs.deployment.jaxrsscanningprocessor.scan(jaxrsscanningprocessor.java:209)org.jboss.as.jaxrs.deployment.jaxrsscanningprocessor.deploy(jaxrsscanningprocessor.deploy(jaxrsscanningprocessor.105)

Here the problem is with multiple rest service implementations i.e., one is jboss rest implementation and another one is jersey.So here in this case , you may have to exclude the jaxrs of jboss by creating jboss-deployment-structure.xml file and excluding that.

Example of jboss-deployment-structure.xml 

    <jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
        <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
        <deployment>
            <dependencies>
                <module name="org.jboss.as.jpa"/>
                <module name="org.hibernate"/>

            </dependencies>
            <exclude-subsystems>
                <subsystem name="jaxrs" />

            </exclude-subsystems>
            <exclusions>
                <!-- <module name="org.jboss.as.jsf"/> -->
                <module name="org.jboss.as.jaxrs"/>
                <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider"/>
                <module name="com.fasterxml.jackson.core.jackson-annotations"/>
                <module name="com.fasterxml.jackson.core.jackson-databind"/>
                <module name="com.fasterxml.jackson.core.jackson-core"/>

            </exclusions>
        </deployment>
    </jboss-deployment-structure>
