我的 Camunda 网络应用程序突然拒绝连接。当我执行 localhost:8080 时，我得到 ERR_CONNECTION_REFUSED by localhost
http://localhost:8081/ 正在运行(我的 Spring Boot 应用程序在其中提供 REST API)。

最佳答案
通过在 application.properties 中设置 server.port=8081，您将整个 http 服务器配置为监听端口 8081。因此 Web 应用程序将不可用在 8080 上。
从描述中我无法判断您的“Spring Boot Rest API”是如何配置的，但我认为它会干扰 camunda 网络应用程序，因为它使用相同的基本路径。
如果您的目标是在不同的 URL 下公开基于 Spring Data 的 API，那么设置不同的基本路径可能会解决问题。设置
spring.data.rest.basePath=/uniquetext
(可能还有 spring.data.rest.defaultMediaType = application/json)
并改为在此基本路径下访问您的 API。
如果这不能解决问题，在 src/main/resources 中包含一个 logback.xml 并根据您的需要调整日志级别可能有助于您诊断问题.示例:
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<!-- encoders are assigned the type ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<root level="debug">
<appender-ref ref="STDOUT" />
</root>
<logger name="org.apache.ibatis" level="info" />
<logger name="javax.activation" level="info" />
<logger name="org.springframework" level="info" />
<logger name="org.camunda" level="info" />
</configuration>
