After Upgrading Spring-boot version, we are having circular depenencies problems. So
I want to see this with the current version of Spring-boot 2.2.13.RELEASE
So I added the following config to my application.yml.
spring.main.allow-circular-references = false
The problem is that it gives me an "Unknown property 'spring.main.allow-circular-references'"?
Is it Normal?
Kind regards,
If you are in a YML, the "normal" way to declare this property is like this:
spring:
main:
allow-circular-references: true
The default value since the last Spring version is false, so if you want to boot you need to start you need to set it to true (and fix it ;) )

I was wondering if we can supply a custom attribute (a key to be in application.properties file), I know for sure that -Dserver.port=8080 works, and overrides the property value, but server.port is a spring boot's expected property value.
How about something other than that, for example a jdbc connection string or service name? does -Ddb.service.name=dbservice work?
Yes, any property can be set via system property. You can use -D or -- notation. There are also a variety of property sources Spring Boot uses:
https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html
I see following in Spring Boot application.properties file. What is it doing here:
spring.datasource.password = ${DB_PASSWD:password}
It means try resolving DB_PASSWD property. If found, use it's value. If not, use the default provided value password. In short:
${property:defaultValue}
The property value is looked up from property sources registered in Spring context, see Environment.getProperty() and #PropertySource.
Spring Boot here. What are the possible values that one can specify for the management.trace.include property in application.properties, what are this property's default values, and where is all of this documented (pro tip: it's not!)?
For Spring Boot 2.1.0 it is:
org.springframework.boot.actuate.trace.http.Include
To see its values, see (enum constansts are processed by Spring - AUTHORIZATION_HEADER becomes authorization-header):
https://docs.spring.io/spring-boot/docs/2.1.0.RELEASE/api/org/springframework/boot/actuate/trace/http/Include.html#enum.constant.summary
Default value can be found here:
https://docs.spring.io/spring-boot/docs/2.1.0.RELEASE/reference/html/common-application-properties.html
Twas: org.springframework.boot.actuate.trace.TraceProperties.Include
I have a Spring Boot Hystrix dashboard application where in a .property file I am trying to define some key/value pair(s) ― as per tutorial: https://exampledriven.wordpress.com/2016/07/05/spring-cloud-hystrix-example/
I am getting error when adding property eureka.client.healthcheck.enabled = true. The editor complains with:
Unknown property 'eureka.client.healthcheck'
Please, help me to find out the correct dependency, or if I am missing anything else.
I am trying to set the hibernate.id.new_generator_mappings property in order to use SequenceStyleGenerator, as I'm getting deprecation warnings for SequenceHiLoGenerator after upgrading to Spring Boot 1.4.0.RELEASE.
I tried adding the following entry to application.yaml but it has no effect:
spring:
jpa:
hibernate:
id:
new_generator_mappings: true
I also tried converting to application.properties file:
spring.jpa.hibernate.id.new_generator_mappings=true
Stepping through the JpaProperties class I can see where it's trying to parse the hibernate.id.new_generator_mappings property, but it is missing.
Is this a bug in Spring Boot, or do I have something configured incorrectly?
The correct setting, per the upgrade guide is:
spring.jpa.hibernate.use-new-id-generator-mappings
