Solution

  • Although you tested similar approaches, please, consider review this Github issue, especially the last comment, I think it can be helpful.

    Be sure to have an appropriate version of the JAXB runtime as well. In your previous issues it looks like Spring was unable to find a suitable JAXB implementation in your classpath. For the version of the jaxb-api that you indicated in your dependencies, 2.3.1, please, remove the dependencies related with com.sun.xml.bind and include the following one:

    implementation group: 'org.glassfish.jaxb', name: 'jaxb-runtime', version: '2.3.1'
    

    The recent org.glassfish.jaxb jaxb-runtime versions, say 3.0.0, depends on org.glassfish.jaxb jaxb-core which in turn depends on jakarta.xml.bind jakarta.xml.bind-api, the Eclipse Foundation based JAXB implementation for Java EE. If you want to use org.glassfish.jaxb:jaxb-runtime:3.0.0 include the following dependency:

    implementation group: 'jakarta.xml.bind', name: 'jakarta.xml.bind-api', version: '3.0.0'
    

    instead of the previous JAXB API one you defined:

    implementation group: 'javax.xml.bind', name: 'jaxb-api', version: '2.3.1'
    

    Please, change your imports in consequence and test it carefully, I never tested it with Spring WebClient and the related JAXB codecs.

    Regarding the problem with the section repetition, it seems that JAXB is trying to serialize both field and methods defined properties of your POJOs. To avoid the problem, explicitly define the access type using the @XmlAccessorType annotation. For example:

    @XmlRootElement(name="DirectoryOfService")
    @XmlAccessorType(XmlAccessType.FIELD)
    public class DirectoryOfService {
    
        @XmlElementRef(name = "Section")
        private Section section;
    
        
        public Section getSection() {
            return section;
        }
    
        public void setSection(Section section) {
            this.section = section;
        }
    
    }
    
    @XmlRootElement(name="Section")
    @XmlAccessorType(XmlAccessType.FIELD)
    public class Section {
    
        @XmlElementRef(name = "Test")
        private List<Test> test;
        @XmlAttribute(name = "Name")
        private String name;
        //public String text;
    
        public List<Test> getTest() {
            return test;
        }
    
        
        public void setTest(List<Test> test) {
            this.test = test;
        }
    
        
        public String getName() {
            return name;
        }
    
        
        public void setName(String name) {
            this.name = name;
        }
    
    }
    
    @XmlRootElement(name = "Test")
    @XmlAccessorType(XmlAccessType.FIELD)
    public class Test {
    
        @XmlElement(name = "Name")
        private String name;
        @XmlElement(name = "Code")

        public void setValidFrom(Date validFrom) {
            this.validFrom = validFrom;
        }
    
        
        public String getIncludes() {

        }
    
        
        public void setIncludes(String includes) {
