jackson-databind-nullable | JsonNullable wrapper class and Jackson module | JSON Processing library

it's not the first time this question was asked and i read a lot of article about this topic, but I can't solve this problem:

Field dataSource in de.foo.MariaDbConfig required a bean of type 'javax.sql.DataSource' that could not be found.

All my configurations are like in this articles. Code generation worked properly with a given ddl sql file. The database is a MariaDB. Why does this error keep appearing?

Config

I am trying to experiment by building some simple API's with apache camel. The request body for a post request is empty but camel doesn't return bad request instead it returns 201.

Here is what I do;

1. Generate classes from studentreg-api.yaml [This is a valid openapi 3 yaml document]
2. Using camel, spring boot to build REST endpoints Step
3. Configured camel rest endpoint with clientRequestValidation(true)
4. Start the server
5. Open /api-docs and validated if the mandatory attributes are marked appropriately
6. From postman made request to the POST endpoint with blank request body

Expected: 400 - Bad request Actual: 201

I couldn't figure out what is that I am missing.

I've searched Stack and google looking for an answer to no luck. So I'm hoping someone can help me here.

I have a Spring Boot API which is currently using Tomcat, now I've read about some of the performance improvements in Undertow so I wanted to give it a go and see for myself.

Now, I've removed my spring-boot-web-starter dependancy and added undertow however I'm getting the following errors in a few classes and I can't seem to find how to resolve them:

We are using the openapi-generator-maven-plugin version 5.0.1 to generate our APIs. I am trying to specify a request that includes a DTO and also a file.

The first weird thing is that the generated code doesn't use the DTO, it basically flattens the fields, so that the API expects each of the fields to be specified. However, we're not really too concerned about this issue, because we can just specify each field (although it would be nice if it worked as expected).

The problem that is killing us is that the generated classes for the API and the API Delegate are not consistent with each other. The generated API treats each of the fields as a String. However, the API Delegate treats them as Optional. So when we try to compile the code, the API gets a compile error because it's passing String to the Delegate, and the Delegate wants Optional.

Here is our POM, with the related dependencies and plugin config:

How can I disable JSR-303 annotation processing in springdoc for specific fields?

I have the following request class MyRequestTO where the field name is actually optional. The @NotBlank annotation is only applied to the unwrapped JsonNullable. This means the user is allowed to omit the field when sending MyRequestTO but if set it must not be blank. However the open api doc marks the name field as required. Changing the @Schema annotation to @Schema(type = "string", required = false) does not help.

I want to avoid a solution where I have to write my own annotation and make use of org.springdoc.core.customizers.OpenApiCustomiser. The desired solution should also work for other types like JsonNullable annotated with @NotNull.

Following is my build.gradle configuration:

I'm trying to test openapi codegenerator via gradle plugin. So, I have .yml file with documentation (ran it in https://editor.swagger.io/ , looks cool)

I've recently started using Avro and Kafka in my spring boot project. Now I've googled this and can't seem to find a straight answer.

When I build my war via my gradle build file, can I include the classes autogenerated from Avro schema?

Look at the war file when its exploded it doesnt seem to include those classes.

Here is my build.gradle file.

Many thanks for reading this question and if you have the time to help!

I'm having an issue with getting my Kafka / confluent spring boot with gradle project up and running. I originally had just a producer in this test project and everything was running well. I then added a Kafka consumer and now I get an exception on start up. Would anyone be able to spot the problem here:

Firstly this is the stacktrace
