春季引导版本2.4.4 Java版本15

代码语言：javascript
运行
复制
@Bean
    public WebClient webClient() {
        return WebClient.builder().baseUrl(BASE_URL)
                .defaultHeaders(header -> header.setBasicAuth("test",
                        "testpwd"))
                .clientConnector(new ReactorClientHttpConnector(HttpClient.newConnection()))
                .exchangeStrategies(ExchangeStrategies.builder().codecs(configurer -> {
                    configurer.defaultCodecs().jaxb2Encoder(new Jaxb2XmlEncoder());
                    configurer.defaultCodecs().jaxb2Decoder(new Jaxb2XmlDecoder());
                }).build()).build();
        
    }

使用Spring 2.4.4 webclient并尝试使用XML来使用该服务。

代码语言：javascript
运行
复制
public Mono<ServerResponse> retrieveServices() {

        // Headers can be passed here or while building the client
        Mono<DirectoryOfService> serviceMono = webClient
             .get().uri("/api/v1/test/services")
            .header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_XML_VALUE)
            .accept(MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML)
            .retrieve().bodyToMono(DirectoryOfService.class);

    }

错误：-

尽管您测试了类似的方法，但请考虑一下这个吉特布问题，特别是最后评论，我认为这是有帮助的。

也一定要有JAXB运行时的适当版本。在前面的问题中，Spring似乎无法在类路径中找到合适的JAXB实现。对于您在依赖项中指示的jaxb-api版本，2.3.1，请删除与com.sun.xml.bind相关的依赖项，并包括以下一个：

代码语言：javascript
运行
复制
implementation group: 'org.glassfish.jaxb', name: 'jaxb-runtime', version: '2.3.1'

最近的org.glassfish.jaxb jaxb-runtime版本，比如3.0.0，依赖于org.glassfish.jaxb jaxb-core，而后者又依赖于基于jakarta.xml.bind jakarta.xml.bind-api的Java的JAXB实现。如果要使用org.glassfish.jaxb:jaxb-runtime:3.0.0，请包括以下依赖项：

代码语言：javascript
运行
复制
implementation group: 'jakarta.xml.bind', name: 'jakarta.xml.bind-api', version: '3.0.0'

而不是之前定义的JAXB：

代码语言：javascript
运行
复制
implementation group: 'javax.xml.bind', name: 'jaxb-api', version: '2.3.1'

请更改您的导入，并对其进行仔细的测试，我从未用SpringWebClient和相关的JAXB代码对其进行测试。

关于section重复的问题，JAXB似乎试图序列化您的POJO的字段和方法定义的属性。为了避免这个问题，使用@XmlAccessorType注释显式定义访问类型。例如：

代码语言：javascript
运行
复制
@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;
    }

}
代码语言：javascript
运行
复制
@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;
    }

}
代码语言：javascript
运行
复制
@XmlRootElement(name = "Test")
@XmlAccessorType(XmlAccessType.FIELD)
public class Test {

    @XmlElement(name = "Name")
    private String name;
    @XmlElement(name = "Code")
    private String code;
    @XmlElement(name = "Replicate")
    private int replicate;
    @XmlElement(name = "ValidFrom")
    private Date validFrom;
    @XmlElement(name = "Includes")
    private String includes;
    @XmlElement(name = "Currency")
    private String currency;
    @XmlElement(name = "NonDiscountable")
    private boolean nonDiscountable;

    public String getName() {
        return name;
    }

    
    public void setName(String name) {
        this.name = name;
    }

    
    public String getCode() {
        return code;
    }

    
    public void setCode(String code) {
        this.code = code;
    }

    
    public int getReplicate() {
        return replicate;
    }

    
    public void setReplicate(int replicate) {
        this.replicate = replicate;
    }

    
    public Date getValidFrom() {
        return validFrom;
    }

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

    
    public String getIncludes() {
        return includes;
    }

    
    public void setIncludes(String includes) {
        this.includes = includes;
    }

    
    public String getCurrency() {
        return currency;
    }

    
    public void setCurrency(String currency) {
        this.currency = currency;
    }

    
    public boolean isNonDiscountable() {
        return nonDiscountable;
    }

    
    public void setNonDiscountable(boolean nonDiscountable) {
        this.nonDiscountable = nonDiscountable;
    }
