My requirement is that , I need to build a web client and a RMI desktop application , which connects to a RESTful web service to conduct crud operation. I only need to use the web application to view the data in the database , but the desktop application needs to be able to conduct CRUD operations. The above provided diagram is the architecture I need to follow to develop my application. For

我的Spring Cloud（七）：Feign 声明式接口调用

一、什么是Feign Feign也是去实现负载均衡，但是它的使用要比Ribbon更加简化，它实际上是基于Ribbon进行了封装，让我们可以通过调用接口的方式实现负载均衡。Feign和Ribbon都是由Netflix提供的，Feign是一个声明式、模板化的Web Service客户端，它简化了开发者编写Web服务客户端的操作，开发者可以通过简单的接口和注解来调用HTTP API，使得开发变得更加简化、快捷。Spring Cloud Feign也是基于Netflix Feign的二次开发，它整合了Ribbon和Hystrix，具有可插拔、基于注解、负载均衡、服务熔断等一系列的便捷功能，也就是说我们在实际开发中可以用Feign来取代Ribbon。 相比较于Ribbon+RestTemplate的方式，Feign大大简化了代码的开发，Feign支持多种注解，包括Feign注解、JAX-RS注解、Spring MVC注解等，Spring Cloud对Feign进行了优化，整合了Ribbon和Eureka，从而让Feign使用更加方便。 二、Ribbon和Feign的区别 Ribbon是一个通用的HTTP客户端工具，Feign是基于Ribbon实现的。 三、Feign的优点 1.Feign是一个声明式的Web Service客户端。 2.支持Feign注解、Spring MVC注解、JAX

JAX-RS 方式的 RESTful Web Service 开发

Web Service 目前在风格上有两大类，一个是基于 SOAP 协议，一个是完全遵循 HTTP 协议规范的RESTful 风格。 SOAP 方式的 web service 已经很成熟了，应用也很广，已经成为 Web Service 的工业标准。不过 RESTful Web Service 现在势头越来越猛，特别是其灵活性以及与 Ajax 的完美结合，让人爱不释手，很有必要了解一下。 RESTful 就是一种架构风格，是对 HTTP 协议的完全遵循。像是人们经历了无止境的对 HTTP 引申、扩展之路后的一种回归，让 web service 开发者重新做回 HTTP 协议的信徒。 RESTful 倡导用 HTTP 协议中的 verb 与实际数据操作的增删改查相对应，如 HTTP 中的 PUT 、 GET 、 POST 、DELETE 分别对应 web 系统中数据的改、查、增、删的操作。当然 RESTful 支持的 http verb 还不仅限于上述 4 个，还有像其他的 HEAD,OPTION ……等，不过上述 4 个已经够我们日常使用了。 目前 Web Service 的框架很多，不过我只用过 CXF ，所以我还是以 apache-cxf2.2.2 为例介绍一下 RESTful Web Service 的开发。 比较常见的 RESTful Web Service 的发布有 JAX

Validating JAX-RS resources and methods (IBM JAX-RS implementation) using bean validation on Websphere Application Server 8.5.5

问题 I am using IBM JAX-RS implementation to develop my REST APIs. I am looking to include validation of resource method parameters using Bean Validation (annotations) support provided in JAX-RS 2.0. I know that Jersey implementation supports this feature (https://jersey.java.net/documentation/latest/bean-validation.html). Is there a similar support available with IBM JAX-RS implementation on WAS 8.5.5? If so could you please direct me to some tutorial on how to accomplish this? I am specifically

JAX-RS writer interceptor works for every response even with NameBinding

问题 I need to intercept a response from the server that was generated for a specific API call and change it. I used the JAX-RS 'WriterInterceptor' for this and I have created a NameBinding as well. But the server is intercepting every response out from the server. What am I doing wrong here? Shown below is the code I have tried. Why is the name binding does not work? (I have verified that when calling other API resources the particular method that I have use name binding is not called.) Name

jersey and jax-rs RI2 - missing HttpServerFactory

问题 I have a simple project to test JAX-RS services. Yesterday I downloaded jersey-1.7.1 and used com.sun.jersey.api.container.httpserver.HttpServerFactory and com.sun.net.httpserver.HttpServer to create a http server to test my services from inside eclipse (w/o a heavy weight container) Today, I downloaded the latest jersey jars (jaxrs-ri) and the HttpServerFactory is missing. Looks like they removed the class between 1.7.1 => 2.0 but I cannot find it in deprecated section. I see grizzly2

Mapping specific constraint validator to specific ContraintViolationException in Jersey

由 自古美人都是妖i 提交于 2020-02-08 02:37:19
问题 I am trying to create a custom validator and mapped it into a specific constraintViolationException. The reason is I want to create different custom exception for different constraint. For example, if a user is not found in the database, a not found violationException is triggered, while if the user has invalid username, a bad response violationException will be executed instead. @Retention(RUNTIME) @Target({ FIELD, METHOD }) @Constraint(validatedBy = UserNotValidValidator.class) public

JAX-RS and unknown query parameters

由 萝らか妹 提交于 2020-02-02 02:43:11
问题 I have a Java client that calls a RESTEasy (JAX-RS) Java server. It is possible that some of my users may have a newer version of the client than the server. That client may call a resource on the server that contains query parameters that the server does not know about. Is it possible to detect this on the server side and return an error? I understand that if the client calls a URL that has not been implemented yet on the server, the client will get a 404 error, but what happens if the
