Spring ActiveMQ問題

Question

有點急請幫忙！

Why do I get IllegalArgumentException Cannot convert value of type String to required type Product, in Spring?

我已經閱讀了這個問題，因爲我得到了類似的例外：

<Feb 13, 2012 11:55:39 AM IST> <Warning> <HTTP> <BEA-101162> <User defined listener org.springframework.web.context.ContextLoaderListener failed: org.springframework.beans.factory.BeanCreationExceptio

我也看到了這個問題的答案，現在在我的情況的問題是： 怎麼辦我發現如果我有類似的定義參數的問題（我個人認爲這不是問題（只是直覺））？或者這是一些其他問題？

請幫助

下面是XML文件：

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

請發表您的Spring配置的詳細信息（XML文件）。現在只有從日誌中可以看出，你正在嘗試將字符串connectionFactory注入。請確保你定義了一個ID爲connectionFactory的bean，它應該是javax.jms.ConnectionFactory，然後用它來注入。

請發佈xml配置。這將有助於進一步調試該問題。

編輯：

根據您輸入，

我沒有看到定義爲<property name="connectionFactory" ...任何地方的bean。你也提到它在其他一些環境上的工作。請檢查哪個xml文件包含此bean的定義，並確保該文件在您發佈的xml中隨Spring一起加載。

Answer 2

你爲什麼不注射任何東西到connectionFactory屬性：

<property name="connectionFactory" value=""/> 

這有可能變爲：

<property name="connectionFactory" ref="amqConnectionFactory"/> 

connectionFactory屬性是javax.jms.ConnectionFactory類型（參見：JmsAccessor.setConnectionFactory()）。

amqConnectionFactory工廠可以被定義如下：

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:amq="http://activemq.apache.org/schema/core" 
    xsi:schemaLocation=" 
     http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
     http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd"> 

    <amq:connectionFactory id="amqConnectionFactory" brokerURL="vm://localhost" /> 

</beans>
