问题 I researched this and found this Answer on SO. I do however have the complementary question to this one: I have a set of filters, that i want to be applied to ALL requests, EXCEPT special cases (eg.: all paths except /mgmt/** and /error/**). This cannot be done using the same method presented in the linked answer, as I would add the filters to the default http-security Object, which would then apply for the special cases too. is there a thing like "negative matchers", allowing me to do

问题 My requirement is, I need to initialize some application resources when server is started in spring boot. In order to initialize those resources, I need bunch of properties. So, I have kept those properties in external property file and I am trying to read the properties in my custom listener when spring boot is started.

问题 My spring boot application throws connection timeout error, and it is never able to connect. The other interesting problem I see is, it is never picking up the connection timeout property defined in spring app properties. org.springframework.amqp.AmqpTimeoutException: java.util.concurrent.TimeoutException at org.springframework.amqp.rabbit.support.RabbitExceptionTranslator.convertRabbitAccessException(RabbitExceptionTranslator.java:74) ~[spring-rabbit-1.6.7.RELEASE.jar:na] at org

问题 We have several Spring Boot apps running as microservices. Each of them are running spring boot actuator to allow us to monitor /metrics, /env, /health, etc. On just one of these services the /env endpoint is returning data as XML when requested in the browser. Further, the XML is invalid, but what I really care about is getting the endpoint to return data in json. The reason the XML is invalid is because we are using Spring Cloud Config and the first element contains the GitHub URL which
