我的 Jersey CORS请求不适用于 POST，但适用于 GET 请求。 header 被映射到 Jersey 请求，如下面对同一资源的 GET 请求的屏幕截图所示。

但是，对以下方法执行 POST 操作会使我最终得到 XMLHttpRequest cannot load http://production.local/api/workstation。 Access-Control-Allow-Origin 不允许来源 http://workstation.local:81。

这是网络 Activity 的屏幕截图:

有关失败的 POST 请求的详细信息:

这是我的资源:

@Path("/workstation")
@Consumes({MediaType.APPLICATION_JSON})
@Produces({MediaType.APPLICATION_JSON})
public class WorkstationResource {

    @InjectParam
    WorkstationService workstationService;

    @POST
    public WorkstationEntity save (WorkstationEntity workstationEntity) {
        workstationService.save(workstationEntity);
        return workstationEntity;
    }

    @GET
    @Path("/getAllActive")
    public Collection<WorkflowEntity> getActive () {
        List<WorkflowEntity> workflowEntities = new ArrayList<WorkflowEntity>();
        for(Workflow workflow : Production.getWorkflowList()) {
            workflowEntities.add(workflow.getEntity());
        }
        return workflowEntities;
    }
}

我的 CORS 过滤器:

public class ResponseCorsFilter implements ContainerResponseFilter {

    @Override
    public ContainerResponse filter(ContainerRequest request, ContainerResponse response) {

        Response.ResponseBuilder responseBuilder = Response.fromResponse(response.getResponse());
        responseBuilder
                .header("Access-Control-Allow-Origin", "*")
                .header("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE, HEAD");

        String reqHead = request.getHeaderValue("Access-Control-Request-Headers");

        if(null != reqHead && !reqHead.equals(null)){
            responseBuilder.header("Access-Control-Allow-Headers", reqHead);
        }

        response.setResponse(responseBuilder.build());

        return response;
    }
}

我的主类中的 Jersey 配置:

//add jersey servlet support
ServletRegistration jerseyServletRegistration = ctx.addServlet("JerseyServlet", new SpringServlet());
jerseyServletRegistration.setInitParameter("com.sun.jersey.config.property.packages", "com.production.resource");
jerseyServletRegistration.setInitParameter("com.sun.jersey.spi.container.ContainerResponseFilters", "com.production.resource.ResponseCorsFilter");
jerseyServletRegistration.setInitParameter("com.sun.jersey.api.json.POJOMappingFeature", Boolean.TRUE.toString());
jerseyServletRegistration.setInitParameter("com.sun.jersey.config.feature.DisableWADL", Boolean.TRUE.toString());
jerseyServletRegistration.setLoadOnStartup(1);
jerseyServletRegistration.addMapping("/api/*");

最佳答案

虽然我认为这是一个 CORS 问题，但事实证明这是一个 Jersey 问题......

org.glassfish.grizzly.servlet.ServletHandler在第 256 行处理异常...

    FilterChainInvoker filterChain = getFilterChain(request);
    if (filterChain != null) {
        filterChain.invokeFilterChain(servletRequest, servletResponse);
    } else {
        servletInstance.service(servletRequest, servletResponse);
    }
} catch (Throwable ex) {
    LOGGER.log(Level.SEVERE, "service exception:", ex);
    customizeErrorPage(response, "Internal Error", 500);
}

在我的日志中，我只看到 service exception:之后什么都没有。当我调试这一行时，我最终看到错误 javax.servlet.ServletException: org.codehaus.jackson.map.JsonMappingException: Conflicting setter definitions for property "workflowProcess": com.production.model.entity.WorkstationEntity#setWorkflowProcess(1 params) vs com.production.model.entity.WorkstationEntity#setWorkflowProcess(1 params)这给了我一些我可以实际使用的东西。

关于java - Jersey CORS 为 GET 而不是 POST 工作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16718234/
