尽管您测试了类似的方法，请考虑复习 this Github issue, especially the last comment，我认为它会有所帮助。
一定要有合适版本的 JAXB 运行时。在您之前的问题中，Spring 似乎无法在您的类路径中找到合适的 JAXB 实现。对于您在依赖项 2.3.1 中指定的 jaxb-api 版本，请删除与 com.sun.xml.bind 相关的依赖项并包含以下依赖项：
implementation group: 'org.glassfish.jaxb', name: 'jaxb-runtime', version: '2.3.1'
最近的 org.glassfish.jaxb jaxb-runtime 版本，比如说 3.0.0，取决于 org.glassfish.jaxb jaxb-core 而后者又取决于 jakarta.xml.bind jakarta.xml.bind-api，Java EE 的基于 Eclipse Foundation 的 JAXB 实现。如果你想使用 org.glassfish.jaxb:jaxb-runtime:3.0.0 包括以下依赖项：
implementation group: 'jakarta.xml.bind', name: 'jakarta.xml.bind-api', version: '3.0.0'
而不是之前的 JAXB API 您定义的：
implementation group: 'javax.xml.bind', name: 'jaxb-api', version: '2.3.1'
请更改您的导入并仔细测试，我从未使用 Spring WebClient 和相关的 JAXB 编解码器对其进行测试。
关于 section 重复的问题，似乎 JAXB 正在尝试序列化 POJO 的字段和方法定义的属性。为避免该问题，请使用 @XmlAccessorType 注释显式定义访问类型。例如：
@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")
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;
}
}
Spring boot version 2.4.4
Java version 15
@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 启动 2.4.4 webclient 并尝试使用具有 XML 响应的服务。
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);
}

尽管您测试了类似的方法，请考虑复习 this Github issue, especially the last comment，我认为它会有所帮助。
一定要有合适版本的 JAXB 运行时。在您之前的问题中，Spring 似乎无法在您的类路径中找到合适的 JAXB 实现。对于您在依赖项 2.3.1 中指定的 jaxb-api 版本，请删除与 com.sun.xml.bind 相关的依赖项并包含以下依赖项：
implementation group: 'org.glassfish.jaxb', name: 'jaxb-runtime', version: '2.3.1'
最近的 org.glassfish.jaxb jaxb-runtime 版本，比如说 3.0.0，取决于 org.glassfish.jaxb jaxb-core 而后者又取决于 jakarta.xml.bind jakarta.xml.bind-api，Java EE 的基于 Eclipse Foundation 的 JAXB 实现。如果你想使用 org.glassfish.jaxb:jaxb-runtime:3.0.0 包括以下依赖项：
implementation group: 'jakarta.xml.bind', name: 'jakarta.xml.bind-api', version: '3.0.0'
而不是之前的 JAXB API 您定义的：
implementation group: 'javax.xml.bind', name: 'jaxb-api', version: '2.3.1'
请更改您的导入并仔细测试，我从未使用 Spring WebClient 和相关的 JAXB 编解码器对其进行测试。
关于 section 重复的问题，似乎 JAXB 正在尝试序列化 POJO 的字段和方法定义的属性。为避免该问题，请使用 @XmlAccessorType 注释显式定义访问类型。例如：
@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")
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;
}
}
