Spring Cloud 加@EnableDiscoveryClient后一直说yml中的数据源url有问题?

@EnableDiscoveryClient
@SpringBootApplication
//指定扫描的mapper接口所在的包
@MapperScan(basePackages = {"com.study.eurekaclient.mapper"}, sqlSessionFactoryRef = "sqlSessionFactory")
//启动注解事务管理
@EnableTransactionManagement

sqlSessionFactoryBean.setDataSource(dataSource);
sqlSessionFactoryBean.setTypeAliasesPackage(TYPE_ALIASES_PACKAGE);
sqlSessionFactoryBean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources(MAPPER_LOCATION));
return sqlSessionFactoryBean.getObject();
}

SpringApplication.run(EurekaClientApplication.class, args);

自问自答一下吧,大家注意一下mybatis-spring和mybatis的版本就好了,着实是个坑啊(主要是不会用idea)

springcloud项目中 idea中编辑yml有些有提示,有些没有提示的问题

为什么有些是有提示,有些没有提示,比如spring开头的基本都有提示,但是eureka没有提示,还有spring开头的spring.jpa.properties.hibernate.dialect也没有提示,这是为什么呢? ![图片说明](https://img-ask.csdn.net/upload/201909/21/1569054823_37194.png)

springcloud config无法从git读取yml文件

MapPropertySource {name='https://github.com/LIUYC1995/SpringcloudConfig/respo/config-client-dev.yml'}]} 报错: Could not resolve placeholder 'foo' in value "${foo}" git文件后缀名改成properties 就可以了,但是用yml后缀config-client项目一启动就报错

springcloud config client 为什么一定要用bootstrap.yml

刚学习springcloud 发现springcloud config client 有一个bootstrap命名的文件, 于是改成application.yml 发现报错了, 网上搜了一下答案说是 bootstrap.yml文件优先级高于application.yml文件, 也说是boostrap用于应用程序上下文的引导阶段,但是不懂,既然先访问的是 springcloud config client文件肯定先加载其配置文件,就算配置成application.yml也没问题吧(还是弄不懂)?

SpringCloud Ribbon 通过配置文件配置负载均衡策略无效

在看SpringCloud官方文档的时候,发现Ribbon可以通过配置文件方式来修改负载均衡策略,但是实际测试不生效。 yml配置如下: ``` # 服务提供者应用名称 sc-ribbon-producer: ribbon: # 指定服务提供者负载均衡策略 NFLoadBalancerRuleClassName: com.netflix.loadbalancer.RandomRule ``` 实际测试中发现并没有使用随机策略,还是用的原始的轮询。 官方文档对应章节: https://springcloud.cc/spring-cloud-dalston.html#_customizing_the_ribbon_client_using_properties 希望大神帮提点一下。

学完一个电商项目以及springboot,在学SpringCloud之前应该学什么基础?

学完Spring boot了,但是spring cloud看不懂。比如yml文件,比如RestTemplate,以及JpaRepository<User,Long>讲师只是上来就讲,代码要这么写。但是从来不说这些都是什么。为什么这么写。所以我第一时间想到在学习Springcloud之前我是不是少学了某些基础性的东西? 我用的是51cto的教程。讲师给我的感觉就是:学生知道这些知识,他只是复述一遍学生应该掌握的东西。但我是第一次学,我根本不知道他要干什么。所以在这之前我应该先???

springcloud stream 下如何配置rocketmq双主双从模式

springcloud stream 下如何配置rocketmq双主双从模式

springcloudbus消息总线远程配置没有自动更新

最近在学习springcloud集成,在看到消息总线这块儿的时候照着网上的方法做了个测试,但是在访问localhost:端口号/actuator/bus-refresh这个接口以后,并没有获取到远程配置的更改,我客户端的controller类,也加了@Rescope这个注解,但是我的服务端的控制台我看返回的是 o.s.cloud.bus.event.RefreshListener : Received remote refresh request. Keys refreshed [] 这是不是服务端上就没有获取到更新的意思? 我还要自己在浏览器输入 localhost:12000/base-dev.yml 这个以后,控制台才能获取显示 Fetched for remote master and found 1 updates 好像消息总线服务端压根儿就没有生效,而且我服务端获取了消息后,客户端也没有发生变化,还是需要重启才能重新加载配置更改,请高人指点下,我是不是哪里配置或是依赖错了,谢谢。 我的springboot是2.2.4,springcloud是Hoxton.SR3,不知道是不是跟版本用的太新了有关系,因为配置上实在是看不出问题了,只是不生效,没有任何报错信息 服务端application.yml ``` server: port: 12000 spring: application: name: bus-server cloud: config: server: git: uri: ******** username: ****** password: ****** rabbitmq: host: 192.168.159.130 username: guest password: guest #暴露触发消息总线的地址 management: endpoints: web: exposure: include: 'bus-refresh' ``` 客户端bootstrap.yml ``` spring: cloud: config: name: base profile: dev label: master uri: http://127.0.0.1:12000 ``` 远程配置文件dev-base.yml ``` server: port: 9001 spring: application: name: bus-client datasource: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://127.0.0.1:3306/testclient?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false username: root password: root jpa: database: mysql show-sql: true rabbitmq: host: 192.168.159.130 username: guest password: guest eureka: client: service-url: defaultZone: http://127.0.0.1:6868/eureka/ instance: prefer-ip-address: true ``` pom.xml ``` <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-bus</artifactId> <version>2.2.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-bus-amqp</artifactId> <version>2.2.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> ```
