see https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-4.0-Migration-Guide#aop-starter-pom

and replace spring-boot-starter-test by spring-boot-starter-webmvc-test
(which brings in spring-boot-starter-test as transitive dependency)

https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-4.0-Migration-Guide#deprecated-starters
https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-4.0-Migration-Guide#test-code

as it does not appear to do anything

as mentioned in https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-4.0-Migration-Guide#test-code

cannot find this in spring-data-commons release notes, but see e.g. spring-projects/spring-data-neo4j@1c11be9

and fix corresponding RestTemplateBuilder import
and replace deprecated setConnectionTimeout and setReadTimeout calls

https://docs.spring.io/spring-boot/3.4/api/java/org/springframework/boot/web/client/RestTemplateBuilder.html

bringing in the metrics and sparql proxy

pulling in fixes to metrics config and default profile

pulling in the updated cors config and the fix for removed .apply() method in SecurityConfig

…Server

these have been moved from org.springframework.boot.test.autoconfigure.web to two different packages

…onding metrics imports

see spring-projects/spring-boot#50788

because spring-boot-starter-actuator already pulls that in
https://github.com/spring-projects/spring-boot/blob/2edca39504f8e9c2943262d3e60ba34b0e7751ac/starter/spring-boot-starter-actuator/build.gradle#L25

it is not used, and also gives rise to the following error in spring-boot 4:
incompatible types: org.springframework.http.HttpHeaders cannot be converted to java.util.Map<java.lang.String,java.util.List<java.lang.String>>

class has been moved to org.springframework.boot.resttestclient package in spring-boot 4

because org.springframework.boot.http.client.ClientHttpRequestFactorySettings has been removed, apparently

…alueMap

pulling in the checkstyle rule to allow long URls in inline comments

was listed under 'Test' dependencies, but does not specify the test scope

This is available via spring-boot starters (jetty?), but we depend heavily on this package and import explicitly from it, so better make the dependency explicit.
The package version is managed by spring boot.
https://docs.spring.io/spring-boot/appendix/dependency-versions/coordinates.html

for compatibility with spring-boot 4 (spring 7)

because @SpringBootTest no longer provides the TestRestTemplate bean, as mentioned in the migration guide:
https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-4.0-Migration-Guide#using-webclient-or-testresttemplate-and-springboottest

we import directly from the jackson packages in many places, so the dependency should be explicit instead of only transitive

this is the only use of @nullable in the fdp

to get rid of the nullpointerexceptions in tests, like:

Cannot invoke "org.fairdatateam.fairdatapoint.entity.schema.MetadataSchema.getTargetClasses()"
    because the return value of "java.util.Map.get(Object)" is null at
    org.fairdatateam.fairdatapoint.service.resource.ResourceDefinitionTargetClassesCache.lambda$computeCache$2(ResourceDefinitionTargetClassesCache.java:84)

pulling in DRY project versioning and some dependency updates

alternative would be something like:

```java
@configuration
public class MongoClientConfig extends AbstractMongoClientConfiguration {

    @value("${spring.mongodb.database}")
    private String databaseName;

    @OverRide
    protected void configureClientSettings(MongoClientSettings.Builder builder) {
        builder.uuidRepresentation(UuidRepresentation.STANDARD);
    }

    @OverRide
    protected @nonnull String getDatabaseName() {
        return databaseName;
    }
}
```

…onCreator

fixes the "Cannot map `null` into type `boolean`" error

also see FasterXML/jackson-databind#5318 and https://github.com/FasterXML/jackson/wiki/Jackson-Release-3.0#jackson-databind

* change MetadataSchemaDraftDTO.abstractSchema boolean to Boolean

  this fixes the following error: "Cannot map null into type boolean (set DeserializationFeature.FAIL_ON_NULL_FOR_PRIMITIVES to 'false' to allow)"

* replace ObjectMapper by JsonMapper with new builder api

  - fix corresponding imports: com.fasterxml.jackson moved to tools.jackson except for com.fasterxml.jackson.annotation
  - replace JsonProcessingException by JacksonException
  - replace MappingJackson2HttpMessageConverter by JacksonJsonHttpMessageConverter

while we're at it

because the original method is deprecated for removal

because it is imported everywhere in the code, but was only included transitively (implicitly)
