将流引用关联到java组件mule

Question

我有一个主流，它以http端点开始，然后是一个实现接口的soap组件，然后是实现该接口的java组件1。现在，我想添加一个流引用，然后添加一个实现相同接口的java组件2。我遇到了"找不到入口"的问题我现在正在关注这个教程博客。mulesoft.org/mule-chool-invoking-component-methods-using-entry-point-resolvers/

下面是我的流程。

<flow name="CreateAccountFlow1" doc:name="CreateAccountFlow1"> 
    <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" 
            doc:name="HTTP" path="bank"/> 
    <cxf:jaxws-service doc:name="SOAP" serviceClass="com.essai2.AccountService"/> 
    <component class="com.essai2.AccountRequest" doc:name="Java"/> 
    <logger level="INFO" doc:name="Logger"/> 
    <flow-ref name="Projet2Flow1" doc:name="Flow Reference"/> 
    <component class="com.essai2.AccountResponse" doc:name="Java"/> 
    <logger level="INFO" doc:name="Logger"/> 
</flow>

有人能帮我吗？

Answer 1

In mule there are many ways to invoke a Java component.
1. Entry point resolver 
2. Implemnt mule Life Cycle API i.e callable
3. Invoke component.
when ever Mule finds Java component as message processors in a flow, tries to execute above three methods .
In the java component if you have created any methods with param same as mule message payload , Entry Point resolver is used.
eg :  class XYZ{
      method1(String s1){
      }
      method2(List<String> S2){
      }
}
If Mule Message Payload has type String then method1 is invoked, if message payload has List of String , method2 is invoked during run time.
2. If you can invoke the Java component in the flow irrespective of type of the payload, should implement Callable interface which overrides onCall() method.
for eg : class XYS implements Callable{
  @override 
  onCall(MuleEventConext muleEventConext){
} 
using MuleEvent Conext you can extract the payload and process it.
3. Using Invoke component, you can create the object of the Class and invoke explicitly the method with appropriate Parameters passed.
