java - Mule - 在 Mule 流中设置 spring 对象调用的属性

Question

我正在使用 Mule 3.3.CE

我有一个名为 SpringObject 的类，它实现了 Callable 接口(interface)

package com.threads.test;

import org.mule.api.MuleEventContext;
import org.mule.api.lifecycle.Callable;

public class SpringObject implements Callable {

    private String someData;
    public String getSomeData() {
        return someData;
    }

    public void setSomeData(String someData) {
        this.someData = someData;
    }

    @Override
    public Object onCall(MuleEventContext eventContext) throws Exception {
        System.out.println("CALL SPRING --->>"+someData);

        return eventContext.getMessage();
    }

}    

我的流程是

<http:connector name="httpConnectorEntryPoint" doc:name="HTTP\HTTPS"/>

<spring:beans xmlns="http://www.springframework.org/schema/beans">
<spring:bean id="component" name="component" class="com.threads.test.SpringObject" lazy-init="false">   
</spring:bean>
</spring:beans>
<flow name="TestThreadsFlow1" doc:name="TestThreadsFlow1">
    <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8099" path="m" connector-ref="httpConnectorEntryPoint" doc:name="HTTP"/>
        <set-payload value="#[&quot;ExitA&quot;]" doc:name="Set Payload"/>
        <component doc:name="Java">
            <spring-object bean="component">
                <property key="someData" value="Information"/>
            </spring-object>
        </component>
    </flow>

问题是当我运行流程并使用 http 连接器时，控制台显示

调用 Spring --->>null

代替

CALL SPRING --->>信息

可能是什么？

Answer 1

您可以尝试在流程外配置您的 spring bean，如下所示:

<spring:bean id="component" name="component"
    class="com.threads.test.SpringObject" lazy-init="false">
    <spring:property name="someData" value="Information" />
</spring:bean>

and inside the flow do:

<component>
    <spring-object bean="component" />
</component>
