Apache Camel-Spring Rest端点参考

Question

I have an application using camel rest component. Originally, I use camel version v2.17.0 and every rest endpoint returns http return code 200 when call.

One day when I update my application's camel version to v2.18.0 (without any other change), all rest endpoint returns http return code 404 when call. The same case happens for v2.18.4 and v2.19.0.

I doubt whether there is a change in rest endpoint path reference via Spring. Is anyone know how to correct my setup? The workaround I am using is to move hardcode String back to Spring which does not fit my intention.

Spring setup for Rest Service

<endpoint id="httpAppRouteBuildRemainPath" uri="#{commonUtilService.getEpUtil().getHTTPAppJsonBuildRemainPath()}" />
<endpoint id="httpSysRouteBuildRemainPath" uri="#{commonUtilService.getEpUtil().getHTTPSysJsonBuildRemainPath()}" />
<endpoint id="httpJsonBuildManagementRouteEndPoint" uri="#{commonUtilService.getEpUtil().getHTTPJsonBuildManagementRouteEndpointPath()}" />

<rest path="#commonUtilService.getEpUtil().getHTTPJsonManagementRestPath()">
        <put uri="ref:httpAppRouteBuildRemainPath" id="appHttpRouteReceiver">
                <to uri="ref:httpJsonBuildManagementRouteEndPoint"/>
        </put>
        <put uri="ref:httpSysRouteBuildRemainPath" id="sysHttpRouteReceiver">
                <to uri="ref:httpJsonBuildManagementRouteEndPoint"/>
        </put>
</rest>

Java Setup

public String getHTTPJsonManagementRestPath() {
        return "/worker/json";
}

public String getHTTPAppJsonBuildRemainPath() {
        return "/app/build";
}

public String getHTTPSysJsonBuildRemainPath() {
        return "/sys/build";
}

Update

I change the spring setup to

<rest path="/worker/json">
    <put uri="/app/build" id="appHttpRouteReceiver">
        <to uri="ref:httpJsonBuildManagementRouteEndPoint"/>
    </put>
    <put uri="ref:httpSysRouteBuildRemainPath" id="sysHttpRouteReceiver">
        <to uri="ref:httpJsonBuildManagementRouteEndPoint"/>
    </put>
</rest>
