SpringCloud与微服务Ⅶ --- Feign负载均衡

由 浪尽此生 提交于 2021-01-03 07:35:50
官方文档: https://projects.spring.io/spring-cloud/spring-cloud.html#spring-cloud-feign 一.Feign是什么 Feign 是一个声明式的Web客户端。它使编写Web服务客户端变得更容易,它的使用方法是定义一个接口,然后在上面添加注解,同时也支持JAX-RS标准的注解。Feign也支持可拔插式的编码器和解码器。SpringCloud对Feign进行了封装,使其支持了SpringMVC标准注解和HttpMessageConverts。Feign可以与Eureka和Ribbon组合使用以支持负载均衡。 二.Feign能做什么 Feign旨在编写Java Http客户端更加容易。 前面在使用Ribbon+RestTemplate时,利用RestTemplate对http请求的封装处理，形成了一套模板化的调用方法。但是实际开发中,由于对服务依赖的调用可能不止一处,往往一个接口会被多次调用,所以通常都会针对每个微服务自行封装一些客户端类来包装这些依赖服务的调用。所以,Feign在此基础上做了进一步封装,由他来帮助我们定义和实现依赖服务接口的定义。在Feign的实现下,我们只需要创建一个接口并使用注解的方式来配置它(以前是Dao接口上面标注Mapper注解,现在是一个微服务接口上面标注一个Feign即可)

Can't compile Artifactory 7.10.2

由 Deadly 提交于 2021-01-03 07:26:25
问题 After JFrog released the source code for Artifactory 7.10.2, I tried to build it, without success. The project seems to be a maven one (there is a pom.xml in the root project, so I guess so). From the root of the project I gave the usual mvn package , but this resulted in an error: $ mvn package [INFO] Scanning for projects... [ERROR] [ERROR] Some problems were encountered while processing the POMs: [FATAL] Non-resolvable parent POM for org.artifactory:artifactory-parent:7.10.2: Failure to

Alternative to sonar.analysis.mode parameter

由 雨燕双飞 提交于 2021-01-03 06:47:45
问题 I'm using Sonarqube 7.9 and Gitlab with a maven docker image that calls my Sonarqube using mvn --batch-mode verify sonar:sonar -DskipTests=true -Drevision=$REVISION_UNSTABLE $SONAR_OPTS -Dsonar.analysis.mode=issues . The thing is that the parameter sonar.analysis.mode is not used anymore since version 7.4 but I can't find out what parameter do I need to use instead. At the build development branch I just want to check the issues related to the code and I don't want to publish anything. Only
