JDK17 + Spring Boot Starter Web 服务：在模块路径或类路径中未找到 JAXB-API 的实现

Question

我有一个简单的 spring 启动应用程序，我想向 SOAP 端点发送请求。不幸的是，每次我尝试这样做时，我都会收到：javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath。我非常有信心我拥有所有必需的库，但我不知道为什么会这样

我正在使用 JDK17

openjdk 17.0.2 2022-01-18
OpenJDK Runtime Environment Temurin-17.0.2+8 (build 17.0.2+8)
OpenJDK 64-Bit Server VM Temurin-17.0.2+8 (build 17.0.2+8, mixed mode, sharing)

我的 build.gradle 看起来像这样：

implementation("org.springframework.boot:spring-boot-starter-web-services:2.6.6")
implementation('jakarta.xml.bind:jakarta.xml.bind-api:3.0.1')
implementation('org.glassfish.jaxb:jaxb-runtime:3.0.2')
implementation('com.fasterxml.jackson.dataformat:jackson-dataformat-xml:2.13.2')

我的代码如下所示：

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import jakarta.xml.bind.JAXBElement;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import org.springframework.ws.client.core.support.WebServiceGatewaySupport;
import org.springframework.ws.soap.client.core.SoapActionCallback;
import javax.xml.datatype.DatatypeConfigurationException;
import javax.xml.datatype.DatatypeFactory;



@Component
public class MyClient extends WebServiceGatewaySupport {

    XmlMapper xmlMapper = new XmlMapper();

    public MyClient() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        marshaller.setContextPath(CONTEXT_PATH);

        this.setMarshaller(marshaller);
        this.setUnmarshaller(marshaller);
        this.setDefaultUri(API_URL);
    }

 void myMethod(){
...
// AT THIS MOMENT I RECEIVE THE EXCEPTION
        var response = (MyResponseClass) getWebServiceTemplate()
            .marshalSendAndReceive(
                request,
                new SoapActionCallback(CALLBACK_URI)
            );
...
{

如何解决？

spring 尚不支持 Jakarta EE9 - 您需要等待 spring6 - https://spring.io/blog/2021/09/02/a-java-17-and-jakarta-ee-9-baseline-for-spring-framework-6

你应该使用

implementation('jakarta.xml.bind:jakarta.xml.bind-api:2.3.3')
implementation('org.glassfish.jaxb:jaxb-runtime:2.3.6')
