我得到以下错误:
这是堆栈跟踪:

我已经声明了一个空的Application类:
public class ScenarioPlannerApp extends Application{}
我使用以下简单的web服务与URL http://localhost:9050/scenarioplanner/api/models/:
资源代码是:
@Path("")
public class ModelController
{
@GET
@Path("/models/")
@Produces(MediaType.APPLICATION_JSON)
public Response getModels() throws Exception {
ModelService modelService = null;
List<CarModelData> models;
models = modelService.getModelDetails();
logger.debug("Webservice Name [/models/] execution completed with HTTP status OK [200]");
//return Responsestatus(Status.OK).entity(models).build();
return Response
.status(Status.OK)
.entity(models)
.build();
}
我已经阅读了许多关于堆栈溢出的答案，但无法解决此错误。我花了一整天的时间试图调试这个错误，但徒劳无益!
任何帮助将高度重视和赞赏!!
固定应用程序路径
用@ApplicationPath:
Application的类@ApplicationPath("/api")
public class ScenarioPlannerApp extends Application {
...
}
固定资源路径
用/models作为值，用@Path注释ModelController类。在这种情况下，getModels()方法不需要@Path注释:
@Path("/models")
public class ModelController {
@GET
@Produces(MediaType.APPLICATION_JSON)
public Response getModels() throws Exception {
...
}
}
@Path注释指定了资源。创建资源方法
您很可能需要向ModelController资源类添加更多方法。请看下面的例子:
要在/api/models上处理POST请求的方法，可以有以下配置:
@POST
@Consumes(MediaType.APPLICATION_JSON)
public Response createModel(Model model) throws Exception {
...
}
要有一个方法在/api/models/{id}上处理GET请求，您可以有以下命令:
@GET
@Path("/{id}")
@Produces(MediaType.APPLICATION_JSON)
public Response getModel(@PathParam("id") Long id) throws Exception {
...
}
@Path注释指定资源的子资源。
这个问题我已经解决了。这就是我需要做的:
@Path("")
public class ModelController
{
@GET
@Path("/models/")
@Produces(MediaType.APPLICATION_JSON)
public Response getModels() throws Exception {
return Response
.status(Status.OK)
.entity(models)
.build();
}
在上面的代码中，
I had to change the path @Path("") to @Path("/api")
就是这样! !
休息一切都很好!
对于那些正在从2迁移他们的Resteasy版本的人。X到3。X或4.X.
路径匹配算法在JAX-RS 2.0中发生了变化，变得非常严格。
为了让您继续使用您的现有方法的@Path，您必须启用resteasy.wider.request.matching Resteasy配置。
web . xml
<context-param>
<param-name>resteasy.wider.request.matching</param-name>
<param-value>true</param-value>
</context-param>
