REST函数中的两个以上参数导致Jersey 2.0/JAXB 2.2中的ModelValidationException

Question

我有一个问题，我真的无法摆脱。我正在使用嵌入在Eclipse中的玻璃鱼4.0以及JAXB 2.2和泽西岛2.0。我想创建一个REST接口，其中泽西调用的函数需要两个参数。例如，两个路径参数或 JAXB 和一个路径参数的混合。无论哪种方式，我总是得到一个模型验证例外与泽西岛。在函数中只注入一个参数效果很好，但我至少需要两个，有时甚至更多。

我发现这个帖子是关于多部分表单数据的Jersey 2注入源的，但我认为这不是我的解决方案，因为我正在处理GET、POST甚至PUT，不想使用表单数据。最后，不管我使用PUT、POST还是get，我总是得到相同的错误。当然，我可以使用

@Context UriInfo info;

信息，并使用例如

long portID = new Long(uriInfo.getPathParameters().get("portid").get(0));

看来我必须通过玻璃鱼激活某个功能才能激活这个功能。

这是我的代码的一个例子，它不工作

@PUT
@Path("/networkelements/{neid: [0-9]+}/ports/clients/{portid: [0-9]+}")
@Consumes(MediaType.APPLICATION_XML)
public Response fullyUpdateClientPort(@PathParam("neid") long neID, @PathParam("portid") long portID, Ports ports){
    // TODO: Implement REST functionality
    return Response.status(Response.Status.OK).entity("Port(s) fully updated").build();
}

一个很好的例子:

@GET
@Path("/networkelements/{neid: [0-9]+}/ports/clients/")
@Produces(MediaType.APPLICATION_XML)
public Ports getClientPorts(@PathParam("neid") Long neID){
    // TODO: Implement REST functionality
    Ports ports = new Ports();
    for (AbstractPort port : this.data.getPortList()) {
        DebugLogger.get().log(Level.INFO, port.getPortName());
    }
    ports.setPorts(this.data.getPortList());
    return ports;
}

编辑：这些是我得到的例外

编辑编号2：

我现在发现，不幸的是，我在URL中的参数没有被自动解码。我已经通过谷歌搜索了很多，但我还没有发现，如果我必须单独激活的东西，新泽西或Glassfish自动到这一点。通过UriInfo获取这些参数可以很好地工作，并且是目前唯一的解决方法。

当初始化 API 时出现问题时，通常会引发此异常。不一定是导致异常弹出的请求。

尝试查看容器通用日志。尽可能多地评论初始化部分，直到它起作用。尝试思考初始化期间是否执行了一些代码。
