Removes use of JAXB API via jackson-dataformat-xml. Reference Transition from Java EE to Jakarta EE #26041 (comment) .
Getting rid of the JAXB API will make ShardingSphere JDBC Core work out of the box under Spring Boot OSS 3/Quarkus 3/Micronaut Framework 4/Helidon 3 with Jakarta EE 9+. The only limitation is XA distributed transactions. This will completely resolve javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath. #26896.
I know there are quite a few breaking changes on Jackson 3.0. But the problems caused by https://github.com/FasterXML/jackson/wiki/Jackson-Release-3.0 appear to be much smaller than those caused by Jakarta EE 9. And Jackson 3.0 hasn't been released yet.
Revisiting Revise JAXB and javax dependencies in ShardingSphere #16863. I verified on OpenJDK 17.0.9 that shardingsphere-transaction-xa-narayana does not require JAXB at all.
Removes GraalVM Reachability Metadata for org.glassfish.jaxb:jaxb-runtime:2.3.1 which is no longer needed. Passed the test of ./mvnw -PnativeTestInShardingSphere -T1C -e clean test. For Improve GraalVM Reachability Metadata and corresponding nativeTest related unit tests #29052 .
The reason I don't use xstream is because it requires a lot of json entries for the GraalVM Reachability Metadata. Reference How to reduce the amount of metadata when there are a lot of reflections in the code. oracle/graalvm-reachability-metadata#232.
Explicitly introduce com.fasterxml.jackson.datatype:jackson-datatype-jdk8 to adapt to Jackson 2.16.0. Otherwise an error is thrown.

...in/java/org/apache/shardingsphere/mode/repository/standalone/jdbc/sql/JDBCRepositorySQL.java

 @Getter
 public final class JDBCRepositorySQL {

-    @XmlAttribute(required = true)
+    @JacksonXmlProperty(isAttribute = true)


We lost required here? Is there no such property with JacksonXmlProperty?

There is no direct equivalent.

Unfortunately XML is special: due to structure being what it is, empty Element looks either as "Object with no properties" or "empty String".

In Required attribute of @JsonProperty is ignored when deserializing from XML FasterXML/jackson-dataformat-xml#538, the Jackson maintainer has a different opinion on required than the JAXB API. Should I use @JsonProperty to mark required and then set it as follows?

final XmlMapper xmlMapper = new XmlMapper(); xmlMapper.configure(DeserializationFeature.FAIL_ON_MISSING_CREATOR_PROPERTIES, true);

I'm not sure how the JAXB API handles the required attribute.

In my local unit test, jaxb-runtime does not throw an exception for empty elements, but gets null values normally like jackson-dataformat-xml. required seems to be just for IDE censorship.

OK, I see. It could be better to open an issue since we need more investigation.

I opened Without setting @JsonCreator for the POJO, the required attribute in @JsonProperty is not checked FasterXML/jackson-dataformat-xml#625 .

A PR for testing is at Check specific properties when deserializing XML file #29577 .
