Question

这是我的骡子流：

HTTP =＆gt; 记录器 =＆gt; SOAP（CXF） =＆gt;成功之前[ JAVA ] =＆gt;的记录器

春天：

<spring:beans>
    <spring:bean id="propertyConfigurer"
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <spring:property name="locations">
            <spring:list>
                <spring:value>test.properties</spring:value>
            </spring:list>
        </spring:property>
    </spring:bean>
    <spring:bean id="testIntegration"
        class="x.x.x.IntegrationClass" init-method="init">
        <spring:property name="url" value="${destiny.url}" />
        <spring:property name="username" value="${message.username}" />
        <spring:property name="password" value="${message.password}" />
    </spring:bean>
</spring:beans>

流速：

    <http:inbound-endpoint exchange-pattern="request-response"
        host="localhost" port="8087" doc:name="HTTP" />
    <logger message="#[message.payloadAs(java.lang.String)]" level="INFO" doc:name="Logger"/>

    <cxf:jaxws-service doc:name="Test service"
        serviceClass="dynamics.file.request.Requests" />

    <until-successful maxRetries="3"
        secondsBetweenRetries="60" doc:name="Until Successful" synchronous="true">
        <component doc:name="Java">
            <spring-object bean="testIntegration" />
        </component>
    </until-successful>
    <logger message="#[message.payloadAs(java.lang.String)]" level="INFO"
        doc:name="Logger" />
</flow>

Java组件返回一个String（XML但是String），当我使用until-successful时，它显示了这个错误：

Exception thrown inside until-successful org.mule.component.ComponentException: Component that caused exception is: DefaultJavaComponent{Flow_test.component.1805940825}. Message payload is of type: String

有了这个错误，我想我在这里需要任何参数但如果我错了就纠正我：

public void init()
{

    NtlmAuthenticator authenticator = new NtlmAuthenticator(username,password);
    Authenticator.setDefault(authenticator);

    Requestsservice = new Requests();
    clntprt = service.getSolicitudesPort();

    Client client = ClientProxy.getClient(cliente);
    HTTPConduit http = (HTTPConduit) client.getConduit();

    HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
    httpClientPolicy.setAllowChunking(false);

    http.setClient(httpClientPolicy);

    BindingProvider provider = (BindingProvider) clntprt;
    provider.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
                    url);
}

更新

我有init方法，我有实现的方法（例如，这些都有，但还有更多）：

@WebMethod(operationName = "CancelCte", action = "urn:microsoft-dynamics-schemas/codeunit/Requests:CancelCte")
@RequestWrapper(localName = "CancelCte", targetNamespace = "urn:microsoft-dynamics-schemas/codeunit/Requests", className = "x.x.Requests.CancelCte")
@ResponseWrapper(localName = "CancelCte_Result", targetNamespace = "urn:microsoft-dynamics-schemas/codeunit/Requests", className = "x.x.Requests.CancelCteResult")
@WebResult(name = "return_value", targetNamespace = "urn:microsoft-dynamics-schemas/codeunit/Requests")
public String CancelCte(
        @WebParam(name = "xmlInput", targetNamespace = "urn:microsoft-dynamics-schemas/codeunit/Requests") String xmlInput) 
{
    return client.CancelCte(xmlInput);
}

@WebMethod(operationName = "newCte", action = "urn:microsoft-dynamics-schemas/codeunit/Requests:newCte")
@RequestWrapper(localName = "newCte", targetNamespace = "urn:microsoft-dynamics-schemas/codeunit/Requests", className = "x.x.Requests.newCte")
@ResponseWrapper(localName = "newCte_Result", targetNamespace = "urn:microsoft-dynamics-schemas/codeunit/Requests", className = "x.x.Requests.newCteResult")
@WebResult(name = "return_value", targetNamespace = "urn:microsoft-dynamics-schemas/codeunit/Requests")
public String newCte(
        @WebParam(name = "xmlInput", targetNamespace = "urn:microsoft-dynamics-schemas/codeunit/Requests") String xmlInput) 
{
    return client.newCte(xmlInput);
}

像现在一样，自动使用必要的方法。

根据您提供的部分信息，我只能说问题的根源在于：

<spring-object bean="testIntegration" />

基于：Component that caused exception is: DefaultJavaComponent{Flow_test.component.1805940825}

主要问题是Mule无法找到调用自定义组件的方法：有两种方法可以使用String，这可以防止Mule选择合适的＆＃34 ;切入点＆＃34;。解决此问题的两种解决方案：

在调用组件之前，使用方法名称设置名为method的属性作为其值，
使用invoke消息处理器直接调用所需的方法。

作为旁注，似乎此组件执行出站HTTP调用：通常您希望使用Mule HTTP来执行此操作，而不是在自定义代码中执行此操作。首先，您将这些交互隐藏在自定义代码中：查看Mule配置的人不知道涉及到出站HTTP呼叫。此外，Mule本身不会知道，因此无法对这些自定义HTTP调用执行诸如一般生命周期和错误管理，统计信息等任何操作。
