java - 如何从 SOAP 逻辑处理程序获取有效负载对象

Question

我正在学习如何在 JAX-WS SOAP Web 服务中创建逻辑处理程序。在这里，我试图获取有效负载数据并希望打印该数据以进行测试。但我遇到了问题。

这是我的LogincalHandler代码

public class HelloMessengerLogicalHandler implements LogicalHandler<LogicalMessageContext> {

    public void close(MessageContext ctx) {
    }

    public boolean handleFault(LogicalMessageContext ctx) {
        return false;
    }

    public boolean handleMessage(LogicalMessageContext ctx) {
        Boolean outbound = (Boolean) ctx.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
        if(outbound) {
            LogicalMessage message = ctx.getMessage();
            //Source payload = message.getPayload();
            JAXBContext jaxbContext;
            try {
                jaxbContext = JAXBContext.newInstance(Person.class);
                Object jaxbPayload = message.getPayload(jaxbContext);
                System.out.println(jaxbPayload);
            } catch (JAXBException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }

        return true;
    }
}

这是我的网络服务代码:

@WebService
@HandlerChain(file = "handler-chain.xml")
public class HelloMessenger {
    public Person getPerson(String name) {
        return new Person(name);
    }
}

这是我的Person类:

public class Person {

    // Default Constructor & Getters, Setters
    private String name;

    public Person(String name) {
        this.name = name;
    }
    @Override
    public String toString() {
        return "Person [name=" + name + "]";
    }
}

当我发布代码并访问网络服务时，出现以下异常:

javax.xml.ws.WebServiceException: javax.xml.bind.MarshalException

我是新手，我的理解是有效负载对象是 Person，因此它应该在日志中显示 person 对象，但我看到了此错误。

请解释此错误指示什么以及如何在逻辑处理程序中获取有效负载数据？

Answer 1

源负载 = message.getPayload();

然后使用 xmltransformation 或其他方式将 DomSource 对象转换为字符串，它将为您提供有效负载。
