I want a user and password setup that jgit can use without the need to generate a temp

pom父工程dependencyManagement中的jar包在子工程中不写版本号无法引入的问题

由 空扰寡人 提交于 2019-12-09 19:35:40
1.遇到的问题： 本人用的idea，然后在导入别人的项目的时候，pom文件中没有报错了，但是在maven栏目中jar包却一直报红，是因为我没写版本的原因吗？不对呀，我的父工程下已经写了springboot的版本了呀， 难道父工程本身就没有引入进来吗？ 像这种的jar包好多报红的，@SpringBootApplication都无法引入，更别说其他的注解了，都是一个样。 2.解决的办法： 原因是由于spring-cloud-dependencies包的版本问题，应当将版本由Finchley.SR1更改为Finchley.RELEASE，之后更新一下包问题就解决了。 <dependencies> <!-- springCloud --> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Finchley.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> <dependencies> 将version版本改一下就好了， Finchley.RELEASE是正式版的。 还是自己不细心吧，不过最好还是用正式的，用着放心

How to fine-tune the Spring Cloud Feign client?

由 回眸只為那壹抹淺笑 提交于 2019-12-09 13:19:12
问题 The Spring Cloud doc says: If Hystrix is on the classpath, by default Feign will wrap all methods with a circuit breaker. That's good but how do I configure the Hystrix options to ignore certain exceptions? I've an ErrorDecoder implementation that maps HTTP status code to exceptions. If I put @HystrixCommand on the method, does Feign honor that? Our requirement is to log various details about every HTTP call made out to dependencies. Currently I've a decorated RestTemplate that does this.

Unreachable security context using Feign RequestInterceptor

由 空扰寡人 提交于 2019-12-09 12:50:13
问题 The goal is to attach some data from security context using RequestInterceptor, but the problem, that the calling SecurityContextHolder.getContext().getAuthentication() always returns null even though it is not null (I am sure 100%). As I understand that's because the Interceptor is created and is being run in other thread. How could I solve this problem and get actual data from security context? My service: @FeignClient(value = "api", configuration = { FeignConfig.class }) public interface

What's the difference between zookeeper vs spring cloud config server?

由 柔情痞子 提交于 2019-12-09 08:58:58
问题 What's the difference between zookeeper vs spring cloud config server? They both store configurations in server and make them available to clients. When should one be used over the other? 回答1: What's the difference between zookeeper vs spring cloud config server? With the Spring Cloud Config Server you have a central place to manage external properties for applications across all environments. The concepts on config server map identically to the Spring Environment and PropertySource
