问题遇到的现象和发生背景
我把项目注册了成一个服务到windows上一开始能读取到，过一段时间会出现读取不到或者读取到错误的配置，可能是因为断网或者电脑重启。
问题相关代码
这是我的xml文件配置
<service>
<!-- ID of the service. It should be unique across the Windows system-->
<id>collection-pro</id>
<!-- Display name of the service -->
<name>Java 程序</name>
<!-- Service description -->
<description>This service is a service created from a minimal configuration</description>
<!-- Path to the executable, which should be started -->
<executable>C:\java\jre1.8.0_191\bin\java</executable>
<arguments>-Xmx1024m -Dfile.encoding=utf-8 -jar collection-pro.jar --spring.application.name="***" --spring.cloud.nacos.config.prefix="***"</arguments>
</service>
这是我bootstrap配置
spring:
profiles:
active: @profile.name@
cloud:
nacos:
config:
# Nacos 认证用户
username: @config.username@
# Nacos 认证密码
password: @config.password@
# 命名空间 常用场景之一是不同环境的配置的区分隔离，例如开发测试环境和生产环境的资源（如配置、服务）隔离等
namespace: @config.namespace@
# 配置中心地址
server-addr: @config.server-addr@
# 配置对应的分组
group: @config.group@
# 配置文件后缀
file-extension: yaml
# prefix: '***'
refresh-enabled: true
discovery:
namespace: @config.namespace@
server-addr: @config.server-addr@
watch:
enabled: false
username: @config.username@
password: @config.password@
这是我配置文件的命名方式
***-prod.yaml
version
<spring-cloud-alibaba.version>2.2.3.RELEASE</spring-cloud-alibaba.version>
