boot-actuator | 基于SpringBoot2.0 实现的jvm远程监工图形化工具，可以同时监控多个web应用 , 支持远程监控 | Runtime Evironment library

I'm currently working on a microservices application for my internship using Consul for service discovery and feign clients for communicating between the services. When we started working on the existing project which already was built using microservices, we upgraded Spring boot to 2.4.3 & cloud to 2020.0.1, so that we could make use of Java 15 to use records instead of normal classes for dtos. The problem we have now is that, whenever we make a call to a composite service, that will try to retrieve data from multiple services (for example users and teams service), that we get the following stacktrace:

I am trying to run my Spring Boot application in debug mode (the normal run works fine), but it fails. I have tried to switch ports, I have killed all Tomcat processes and generally I have spent a lot of hours trying to solve it unsuccessfully. I work on Ubuntu. My JDK is 1.8.0_292.

The output is the following :

I am puzzled to solve this com.fasterxml.jackson.dataformat.xml.XmlMapper error with Java 11. I want to use XmlMapper only from jackson dependency and that's why excluded from springboot starter web , still cannot figure how to resolve it's dependency. providing as much details as possible -

build.gradle

We have an existing application which is working fine with the SpringBoot 2.2.2.RELEASE. Now we tried to upgrade it to the SpringBoot 2.4.2 version and application is not getting started and throws the following error. In the classpath I could see only one spring-webmvc-5.3.2.jar file.

Below is the pom.xml for the referance:

I have three entities Blog, Comments, ParentChildComment. Comment is mapped using ManyToOne relationship to Blog. ParentChildComment has two columns to store id value of parent_comment and child_comment (this is done to store the info regarding which comment is a reply to another one) and both these columns are mapped using OneToOne relationship to Comment table which I guess is the sourcee of problem. PROBLEM When deleting a blog, comments are deleted due to cascade delete, but the parent_child table is still referncing to table comments which throw error org.springframework.dao.DataIntegrityViolationException: could not execute statement; SQL [n/a]; constraint [fkf3i44d11sgikshmo17q4fq1a4]; nested exception is org.hibernate.exception.ConstraintViolationException The whole trace :

I'am working on a AWS Fargate Cluster setup with Pulumi and my current program already successfully creates a Cluster incl. Fargate Tasks that run a public accessible container image. My image is based on Spring Boot (project code on GitHub):

I can't access to my usersList: if I don't add a user first I can't user neither of the other paths of my controller. here, I can't get my users list unless I add a user first and I am using postgres DB then if I add a user everything else works and it brings me all the users in the database the error that I got

I am attempting to use hibernate validators with SpringBoot and Tomcat and yet continue to get this error

I have a spring boot app that I upgraded from v2.2.x to now be v2.4.3.

I saw in their documentation that there is a new actuator endpoint of /startup, however it does not exist when I start my app.

There is no special requirement according to their documentation here

I am using spring-boot-admin-starter-client v2.4.3 which provides spring-boot-actuator v2.4.3, and i even have management.endpoint.startup.enabled=true in my application.properties file.

Has anyone else used this version of spring boot and gotten this actuator enpoint to work?
