如何在 SOAPHandler 中使用 spring bean

Question

我只想在 handleMessage() 方法中使用一个 spring bean，它在 handler-chain.xml 中调用。

这是我的经纪人-chain.xml:

<jaxws:bindings>
    <handler-chains xmlns="http://java.sun.com/xml/ns/javaee">
        <!-- ====================== -->
        <!-- service based handlers -->
        <!-- ====================== -->
        <handler-chain>
            <handler>
                <handler-name>CustomerHandler</handler-name>
                <handler-class>com.test.ws.handler.CustomerHandler</handler-class>
            </handler>
        </handler-chain>
    </handler-chains>
</jaxws:bindings>

这也是我的 CustomerHandler.java class:

public class CustomerHandler implements SOAPHandler<SOAPMessageContext> {

@Autowired
public ServiceInvokeUtil serviceInvokeUtil;

public Set<QName> getHeaders() {

    return null;
}

public void close(MessageContext context) {

}

public boolean handleFault(SOAPMessageContext context) {
    logSoapMessage(context);
    return false;
}

public boolean handleMessage(SOAPMessageContext context) {


    Boolean isRequest = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
    SOAPMessage soapMsg = context.getMessage();
    // if this is a request, true for outbound messages, false for inbound
    if (isRequest) {

        try {
            SOAPEnvelope soapEnv = soapMsg.getSOAPPart().getEnvelope();
            SOAPHeader soapHeader = soapEnv.getHeader();

            // if no header, add one
            if (soapHeader == null) {
                soapHeader = soapEnv.addHeader();
            }
            Boolean oa = serviceInvokeUtil.createRecord(SoapUtil.getRecordEntity());

            SOAPElement userContextHeader = ConsumerHeaderHelper.createUserContextHeader(context);
            soapHeader.addChildElement(userContextHeader);
            }
            soapMsg.saveChanges();




        } catch (SOAPException e) {
            System.err.println(e);
        }

    } else {

        try {
            SoapUtil.setSoapResponseHeader(soapMsg.getSOAPHeader());
        } catch (SOAPException e) {
            e.printStackTrace();
        }

    }
    logSoapMessage(context);
    return true;
}

这是我的 spring 配置 xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:tx="http://www.springframework.org/schema/tx" 
xmlns:context="http://www.springframework.org/schema/context"

<context:property-placeholder />

<bean id="serviceInvokeUtil" class="com.test.ws.util.ServiceInvokeUtil">
</bean>

当我调用 Web 服务时，spring bean serviceInvokeUtil 为空。如何在 handleMessage 方法中使用 serviceInvokeUtil class 作为 spring bean？

Answer 1

Spring 只有在控制实例创建时才会处理@Autowired 注解。换句话说，您的 CustomerHandler 必须是 bean 以及 ServiceInvokeUtil 才能强制 spring 自动装配它。

Answer 2

我将 SpringBeanAutowiringSupport 扩展到 CustomerHandler class 但它已解决。像这样： public class CustomerHandler extends SpringBeanAutowiringSupport implements SOAPHandler {.....
