我正式对这个拦截器感到困惑。
我已将 Jersey 从 2.4.1 升级到 2.5.1，因为 Jersey/Oracle 修复了影响Swagger工作的包扫描错误。经过大量修改与我们基于 Spring 的服务器集成后，2.4.1 工作相对“正常”（spring-jersey3根本不工作。）现在自从升级到 2.5.1（现在是 2.6-SNAPSHOT）后，我收到每次我向与 API URL 模式匹配的任何内容发出请求时，都会出现以下错误。
我做了什么：
非常感谢帮助/解决方法/调试想法...除了废弃 Swagger、几天的工作和回滚到 2.4.1 之外，我什至不知道还能做什么

我试图了解 HK2 Factory 在 Jersey 应用程序中的实现。
目标：如何实现单例工厂？
// Below is the simple factory implementation
public class MyFactory implements Factory<SomeObject> {
private static final Logger logger = LoggerFactory.getLogger(MyFactory.class);
private final CloseableService closeService;
@Inject
public MyFactory(CloseableService closeService) {
this.closeService = closeService;
}
@Override
public MyFactory provide() {
logger.debug("provide object from MyFactory");
SomeObject objectFromFactory = new SomeObject();
this.closeService.add(() -> dispose(objectFromFactory));
return objectFromFactory;
}
@Override
public void dispose(SomeObject instance) {
// destroy instance
logger.debug("dispose object from MyFactory");
}
}
// and binding
bindFactory(MyFactory.class).to(SomeObject.class).in(Singelton.class);

Client client = null;
try {
URLConnectionClientHandler ch = new URLConnectionClientHandler(new ProxyConnectionFactory(proxyHost, proxyPort));
client = new Client(ch);
WebResource webResource = client.resource(url);
ClientResponse response = ((Builder) webResource.type("application/json").header(authKey, authCreds)).post(ClientResponse.class, input);
String output = (String) response.getEntity(String.class);
System.out.println(output);
if (response.getStatus() != 200) {
System.out.println("Status Failed, Status: " + response.getStatus());
}
else {
System.out.println("Connection Successful!");
//additional code
}
} catch (Exception e) {
System.out.println("Exception occurred");
} finally {
client.destroy();
}
在此代码片段中，ProxyConnectionFactory 是一个设置代理配置的类。它实现了 HttpURLConnectionFactory，这也是 jersey 1.x 接口。
我想使用JAX-RS构建RESTful Web服务(Jersey + Jackson,Jackson用于生成JSON).
我使用Glassfish 4.0作为服务器,netbeans作为IDE.
Web服务工作正常,但目前我没有任何身份验证.
所以现在我正在考虑散列密码的摘要验证,这样你就不需要以纯文本形式传输密码了.另外我想使用https,以便加密数据.
我理解了理论.但我不知道我怎么能用Glassfish在Netbeans中做到这一点.
我看到一些教程在glassfish的管理控制台中做了一些事情.但是,有没有办法在netbeans中做到这一点？我不能在部署应用程序时创建的netbeans中定义一个领域吗？
创建领域和东西之后.我想我需要在我的所有资源(WebServices)中注入某种经过身份验证的"用户"-Object.但我以前从未这样做过.我正在寻找一个很好的教程,它描述了我如何设置摘要认证,注入网络netbeans可以用netbeans做到这一点,这样我就能很好地理解它.
按照Up和在MaE,Jersey和Guice的AppEngine上运行的优秀步骤- 第3部分,除了将对象注入Jersey POJO之外,我已经能够完成所有工作.
我从该配置中唯一的区别是我也集成了Objectify,但这是有效的.
TestClass注入到HelloWorldServlet工作中的实例(单例),但注入POJO 的TestClass和SecondTest(RequestScoped)对象HeyResource总是如此null.
我怀疑HK2和Guice之间的互动应该归咎于此,但这是我与Guice , Jersey 和 HK2的第一个项目,所以我都在海上.
我的配置是:
我使用java/jetty自托管服务器和jersey-2 for java RESTful api.应用程序具有带有属性的application.properties文件.
ConfigurationPropertiesclass读取属性文件并将其加载到java.util.Properties类中.
Jetty服务器实例化以下列方式完成.
// Create and register resources
final ResourceConfig resourceConfig = new ApiServiceConfig()
.register(new DependencyInjectionBinder());
ServletContextHandler contextHandler = new ServletContextHandler(ServletContextHandler.SESSIONS);
contextHandler.setContextPath("/mydomain/api");
Server jettyServer = new Server(8585);
jettyServer.setHandler(contextHandler);
ServletHolder jerseyServlet = new ServletHolder(new ServletContainer(resourceConfig));
contextHandler.addServlet(jerseyServlet, "/*");
// Create web context. Can't use.
//WebApplicationContext webContext = getWebApplicationContext();
// Add web context to servlet event listener.
//contextHandler.addEventListener(new ContextLoaderListener(webContext));
try {
jettyServer.start();
jettyServer.join();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally …是否可以在响应中返回错误响应的验证注释消息？我认为这是可能的，但我注意到我们的项目没有给出详细的错误请求消息。
@NotNull(message="idField is required")
@Size(min = 1, max = 15)
private String idField;
如果发出缺少 idField 的请求，我希望看到“需要 idField”。我正在使用球衣 2.0。我看到的回应是这样的......
{
"timestamp": 1490216419752,
"status": 400,
"error": "Bad Request",
"message": "Bad Request",
"path": "/api/test"
}
这是我的 get API 返回员工列表。
@GET
@Produces(MediaType.APPLICATION_JSON)
@Path("/get")
public List<Employee> getEmployee() {
return employeeFacade.getAllEmployee();
}
我想Employee从ResponseEntity<String>.
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
//headers.setContentType(MediaType.APPLICATION_JSON);
Employee employee = new Employee();
HttpEntity<Employee> entity = new HttpEntity<Employee>(employee, headers);
ResponseEntity<String> result = restTemplate.exchange(uri, HttpMethod.GET, entity, String.class);
System.out.println("result:" + result);
如何使这项工作？
