我正在尝试使用Spring启动服务器注册Spring启动客户端。我在spring boot client中添加了context-path。在没有上下文路径的情况下，它可以在服务器中成功注册。
使用自定义上下文路径，它成功注册了客户端，但显示状态为down且找不到404。
以下是我的application.properties：
server.contextPath: /api
spring.application.name: Order-Service
eureka.client.serviceUrl.defaultZone: ${EUREKA_URI:http://localhost:8180/eureka}
spring.boot.admin.url: http://localhost:1111
management.security.enabled: false
spring.boot.admin.username: admin
spring.boot.admin.password: admin123
server.port: 8081
在注册客户端时，我遇到以下例外情况：
