How can I serve static content from CXF / JAX-RS with my rest API mapped to root context?

阅读更多关于 How can I serve static content from CXF / JAX-RS with my rest API mapped to root context?

问题 I have a rest API using CXF to implement JAX-RS where the REST endpoints are directly on the root context. For example if my root context is localhost:8080/myservice And my endpoints are: localhost:8080/myservice/resource1 localhost:8080/myservice/resource2 But I want to serve static content like this: localhost:8080/myservice/docs/swagger.json In my web.xml I'd like to do something like this: <servlet-mapping> <servlet-name>CXFServlet</servlet-name> <url-pattern>/*</url-pattern> </servlet

Feign源码学习

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> feign介绍 Feign是一款java的Restful客户端组件，Feign使得 Java HTTP 客户端编写更方便。Feign 灵感来源于Retrofit, JAXRS-2.0和WebSocket。feign在github上有近3K个star，是一款相当优秀的开源组件，虽然相比Retrofit的近30K个star，逊色了太多，但是spring cloud集成了feign，使得feign在java生态中比Retrofit使用的更加广泛。 feign的基本原理是在接口方法上加注解，定义rest请求，构造出接口的动态代理对象，然后通过调用接口方法就可以发送http请求，并且自动解析http响应为方法返回值，极大的简化了客户端调用rest api的代码。官网的示例如下： interface GitHub { @RequestLine("GET /repos/{owner}/{repo}/contributors") List<Contributor> contributors(@Param("owner") String owner, @Param("repo") String repo); } static class Contributor { String login; int contributions;

问题 Having a hard time trying to protect an existing CXF JAX-RS service with Kerberos authentication. I went through what seems to be the reference documentation : http://cxf.apache.org/docs/jaxrs-kerberos.html but it did not help much. I'm actually trying to configure Tomcat+CXF to reproduce this kind of Apache configuration (which works) : <Directory /var/www/> AuthType Kerberos KrbServiceName HTTP/fqdn@realm Krb5Keytab /path/to/file.keytab Require valid-user </Directory> jaas.conf and krb5

jax-rs ContextResolver<T> undestanding

阅读更多关于 jax-rs ContextResolver undestanding

问题 But I was trying to understand the usage of Providers in jax-rs. But was not able to understand how ContextResolver can be used. Can someone explain this with some basic example? 回答1: You will see it being used a lot in resolving a serialization context object. For example an ObjectMapper for JSON serialization. For example @Provider @Produces(MediaType.APPLICATION_JSON) public static JacksonContextResolver implements ContextResolver<ObjectMapper> { private final ObjectMapper mapper; public

JAX RS Jersey Schema Validation

阅读更多关于 JAX RS Jersey Schema Validation

问题 How to configure schema validation for JAX-RS RESTFul services? We are using XSD to define the models, and JAXB to generate the java models. 回答1: This is how it's done automatically in ReXSL: XslResolver#addXsdValidatorToMarshaller() (pay attention to the highlighted method). In a nutshell, you need to use setSchema() of your JAXB Marshaller . 来源： https://stackoverflow.com/questions/3886653/jax-rs-jersey-schema-validation
