我正在尝试开发一个rest服务，使用蓝图、apache和apache rs，其中服务实现将由camel处理。

问题是剩下的端点似乎没有分配给骆驼。

这是我得到的例外：

启动Camel: CamelContext(blueprintContext)时发生错误，因为/crm上已经运行了一个端点。

我的蓝图如下：

<?xml version="1.0" encoding="UTF-8"?>

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jaxrs="http://cxf.apache.org/blueprint/jaxrs"
xmlns:cxf="http://cxf.apache.org/blueprint/core"
xmlns:camel="http://camel.apache.org/schema/blueprint"
xsi:schemaLocation="
  http://www.osgi.org/xmlns/blueprint/v1.0.0     http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
  http://cxf.apache.org/blueprint/jaxrs http://cxf.apache.org/schemas/blueprint/jaxrs.xsd
  http://cxf.apache.org/blueprint/core http://cxf.apache.org/schemas/blueprint/core.xsd
  http://camel.apache.org/schema/blueprint/camel-blueprint.xsd">


<jaxrs:server id="customerService" address="/crm" staticSubresourceResolution="true">
    <jaxrs:serviceBeans>
        <ref component-id="customerSvc"/>
    </jaxrs:serviceBeans>
    <jaxrs:features>
        <bean class="io.fabric8.cxf.endpoint.SwaggerFeature"/>
        <bean class="io.fabric8.cxf.endpoint.ManagedApiFeature"/>
    </jaxrs:features>
    <jaxrs:providers>
       <bean class="com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider"/>
    </jaxrs:providers>
</jaxrs:server>




<bean id="customerSvc" class="restfuse.CustomerService"/>

<cxf:bus>
    <cxf:features>
      <cxf:logging />
    </cxf:features>
</cxf:bus>



<camelContext id="blueprintContext" trace="false" xmlns="http://camel.apache.org/schema/blueprint">
<route customId="true" id="timerToLog">
    <from uri="cxfrs:bean:customerService"/>
    <setBody>
        <method ref="helloBean" method="hello"></method>
    </setBody>
    <log message="The message contains ${body}"/>
    <to uri="mock:result"/>
</route>

对于使用蓝图的cxf-rs web服务，我也有同样的问题。如果您尝试将camel cxf组件与cxf定义混合使用，那么当camel上下文开始时，它会尝试创建相同的cxf-rs两次，因此它以:启动Camel: CamelContext(blueprintContext)时发生的错误结束，因为已经有一个端点正在运行.

我设法解决了这个问题，将<from uri=cxfrs:bean:mybean>更改为<from uri=direct:start>，并修改jaxrs:servicebean，直接注入:start端点，并将接收到的对象作为主体发送。

这是我的代码：

blueprint.xml

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:camel="http://camel.apache.org/schema/blueprint"       
   xmlns:jaxrs="http://cxf.apache.org/blueprint/jaxrs"
   xmlns:cxf="http://cxf.apache.org/blueprint/core"
   xsi:schemaLocation="
   http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
   http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd
   http://camel.apache.org/schema/blueprint/cxf http://camel.apache.org/schema/cxf/camel-cxf-blueprint.xsd
   http://cxf.apache.org/blueprint/jaxrs http://cxf.apache.org/schemas/blueprint/jaxrs.xsd
   http://cxf.apache.org/blueprint/core http://cxf.apache.org/schemas/blueprint/core.xsd">


   <jaxrs:server id="rsAuthApiSvc" 
            address="http://localhost:9898/authservice"
            staticSubresourceResolution="true">
      <jaxrs:serviceBeans>
         <ref component-id="pmAuthService"/>
      </jaxrs:serviceBeans>
        <jaxrs:providers>
           <bean class="com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider"/>
       </jaxrs:providers>
   </jaxrs:server>

<bean id="pmAuthService" class="com.platamovil.platamovil.auth.rs.PMAuthService"/>

<camelContext trace="false" streamCache="true" id="authApiContext" xmlns="http://camel.apache.org/schema/blueprint">

    <route id="restApiRoute">
        <from uri="direct:start"/>
        <log message="received from WS: ${body}"/>
        <setBody>
            <constant>{"status":"OK"}</constant>
        </setBody>
    </route>

</camelContext>

pmAuthService豆

  public PMAuthMessage processAuthService(PMAuthMessage in_msg) throws Exception{       

      System.out.println("message arrived");
      return producer.requestBody(in_msg).toString()
  }
