泽西岛子资源定位器错误 [英] Jersey Sub-Resource Locators Error
问题描述
我正在尝试使用Grails 2.3.7的 JSR-311插件。我使用0.10版本,因为我认为0.11需要Grails 2.4。
我使用了 generate-resource
命令为我的域类 Product
创建一个终点。创建两个资源类, ProductCollectionResource
和 ProductResource
。我调整了一下,但基本上它们看起来像这样:
$ b ProductCollectionResource
(''application / json'])
@Produces(['application / json']
@Consumes(['application / json']) ])
class ProductCollectionResource {
$ b $ def productResourceService
@Path('{id}')
@GET
ProductResource getResource(@ PathParam('id')Long id){
ProductResource(productResourceService:productResourceService,id:id)
}
$ GET
响应readAll(@QueryParam( max)Integer max,@QueryParam(offset)整数偏移){
ok productResourceService.readAll(max,offset)
}
}
ProductResource
@Consumes(['application / json'])
@Produces(['application / json'])
class ProductResource {
$ b $ def productResourceService
def id
@GET
Response read(){
ok productResourceService.read(id)
}
}
$ b $readAll
方法在ProductCollectionResource
正常工作 - 当我打开它时,我得到一个产品列表,但是当我试图通过id访问特定产品时(在/ api / products / 123
),我得到以下错误:由MessageException引发:Java类com.myapp.ProductResource的消息正文写入程序和未找到Java类型com.myapp.ProductResource和MIME媒体类型application / json

所以它看起来像是试图编组我的
ProductResource
类到JSON,我认为这并不是我想要的。我认为它应该调用ProductResource.read()
方法,并将返回值从该方法编组为JSON。 h2_lin>解决方案
我对Grails没有任何经验,但是从纯粹的泽西岛的角度来看,你看看你在这里得到什么
<$ p $ ($ {
$ {
$ {$ b $ {
$ c>
这是资源方法(端点)。因此, ProductsResource
将被视为响应主体,就像任何其他资源方法一样。
您似乎是试图使用子资源定位器功能,转发到 ProductsResource
类。为此,子资源定位器( getResource
)不应该有 @HttpMethod
注释。这是区分资源方法和子资源定位器的因素之一。
因此,只需删除 I'm trying to get the JSR-311 plugin working with Grails 2.3.7. I'm using version 0.10, because I think 0.11 requires Grails 2.4. I've used the ProductCollectionResource ProductResource The So it looks like it's trying to marshall my I have no experience in Grails whatsoever, but from a pure Jersey standpoint, look at what you got here This is resource method (endpoint). So the You seem to be trying to use the sub-resource locator functionality, forwarding to the So just remove the 这篇关于泽西岛子资源定位器错误的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋! @GET
来自 getResource
方法。 @GET
已由 ProductsResource $中的
read()
方法建立c $ c>,这就是所谓的。
generate-resource
command to create an end point for my domain class Product
. Two resource classes are created, ProductCollectionResource
and ProductResource
. I've tweaked them a bit, but essentially they look like this:@Path('/api/products')
@Consumes(['application/json'])
@Produces(['application/json'])
class ProductCollectionResource {
def productResourceService
@Path('{id}')
@GET
ProductResource getResource(@PathParam('id') Long id) {
new ProductResource(productResourceService: productResourceService, id:id)
}
@GET
Response readAll(@QueryParam("max") Integer max, @QueryParam("offset") Integer offset) {
ok productResourceService.readAll(max, offset)
}
}
@Consumes(['application/json'])
@Produces(['application/json'])
class ProductResource {
def productResourceService
def id
@GET
Response read() {
ok productResourceService.read(id)
}
}
readAll
method in ProductCollectionResource
works fine - when I hit it, I get back a list of products, however when I try to access a specific product by id (on /api/products/123
), I get the following error:Caused by MessageException: A message body writer for Java class com.myapp.ProductResource, and Java type class com.myapp.ProductResource, and MIME media type application/json was not found

ProductResource
class to JSON, which I think isn't really what I want. I think it should be invoking the ProductResource.read()
method, and marshalling the returned value from that method to JSON.@Path('{id}')
@GET
ProductResource getResource(@PathParam('id') Long id) {
ProductsResource
will be treated as the response body, just like any other resource method.ProductsResource
class. For that to work, the sub-resource locator (getResource
) should not have an @HttpMethod
annotation. That's one of the factors that differentiates a resource method from a sub-resource locator.@GET
from the getResource
method. The @GET
is already established by the read()
method in the ProductsResource
, which is what will be called.
