4.1.1 常见问题表现

---

一、nacos的安装与配置

--- 有空再补充

二、nacos注册中心 2.1 对接步骤

pom文件引入nacos依赖

        
            com.alibaba.cloud
            spring-cloud-starter-alibaba-nacos-discovery
            2.0.4.RELEASE
        

添加启动配置

spring:
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
        namespace: ee601b91-4269-4452-bd5f-5010e78b69d8
        service: nacos_service
        group: dev_nacos
        register-enabled: true

启动工程，在nacos界面看到启动的服务

 

三、nacos配置中心 3.1 实验结果

先说结果，需要验证过程的可参看后面的代码和配置再次验证

• 1、nacos可同时加载多个配置，共享配置 spring.cloud.nacos.config.shared-configs 以数组的形式添加配置；
• 2、nacos配置生效的优先级。nacos加载的配置当中，由配置 spring.cloud.nacos.config.name 指定的配置为最高优先级，共享配置 spring.cloud.nacos.config.shared-configs 当中配置的的加载按照添加的顺序加载，即相同的配置项，顺序靠后的覆盖顺序靠前的。
• 3、nacos配置中心当中添加配置时的data id命名需与配置格式相对应。例如：配置格式选择yaml，那data id的命名结尾需要以 .yaml 结尾，否则将获取不到对应的配置。

3.2 对接步骤

引入nacos依赖

        
            com.alibaba.cloud
            spring-cloud-starter-alibaba-nacos-config
            2.0.4.RELEASE
        

添加启动配置

spring:
  cloud:
    nacos:
      config:
        server-addr: 127.0.0.1:8848
        namespace: ee601b91-4269-4452-bd5f-5010e78b69d8
        name: nacos_service
        group: dev_nacos
        file-extension: yaml
        shared-configs:
          - data-id: mysql.yaml
            group: dev_nacos
            refresh: true
          - data-id: priority.yaml
            group: dev_nacos
            refresh: true

nacos配置内容

nacos_service.yaml：

service:
  name: nacos_service_test
config:
  priority: 1

mysql.yaml

spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:336/nacos?characterEncoding=utf8
    username: root
    password: 123456

config:
  priority: 2
  priority2: 2

priority.yaml

config:
  priority: 3
  priority2: 3

接口代码

ConfigController.java

@RestController
@RequestMapping("config")
@RefreshScope
public class ConfigController {

    @Value(value = "${service.name}")
    private String serviceName;
    @Value(value = "${spring.datasource.url}")
    private String dataSourceUrl;
    @Value(value = "${spring.datasource.username}")
    private String dataSourceUsername;
    @Value(value = "${spring.datasource.password}")
    private String dataSourcePassword;
    @Value(value = "${config.priority}")
    private Integer configPriority;
    @Value(value = "${config.priority2}")
    private Integer configPriority2;

    @GetMapping(value = "/get",produces = "application/json")
    public String get() {
        return toString();
    }

    @Override
    public String toString() {
        return "{" +
                "\"serviceName\": \"" + serviceName + '\"' +
                ", \"dataSourceUrl\": \"" + dataSourceUrl + '\"' +
                ", \"dataSourceUsername\": \"" + dataSourceUsername + '\"' +
                ", \"dataSourcePassword\": \"" + dataSourcePassword + '\"' +
                ", \"configPriority\": " + configPriority +
                ", \"configPriority2\": " + configPriority2 +
                "}";
    }
}

工程启动后，接口返回的结果

四、遇到的问题 4.1 版本不对应导致的问题

在添加了nacos的pom文件依赖后，工程启动如出现以下几种异常，通常是alibaba与spring cloud、springboot版本不对应导致的

版本对应关系可到官方github查看：nacos版本说明https://github.com/alibaba/spring-cloud-alibaba/wiki/%E7%89%88%E6%9C%AC%E8%AF%B4%E6%98%8E本文截取部分对应截图贴在下方
