有点急请帮忙！

为什么我在 Spring 中得到 IllegalArgumentException 无法将 String 类型的值转换为所需的 Product 类型？

我已经阅读了这个问题，因为我遇到了类似的异常：

我也看到了这个问题的答案，现在我的问题是：如何确定我是否有定义参数的类似问题（我个人认为这不是问题（只是直觉） )? 或者这是其他问题吗？

请帮忙

这是xml文件：

你为什么不向connectionFactory财产注入任何东西：

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

这必须更改为：

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

connectionFactory属性是类型javax.jms.ConnectionFactory（见：）JmsAccessor.setConnectionFactory()。

amqConnectionFactory工厂可以定义如下：

<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>

请发布您的弹簧配置详细信息（xml 文件）。现在，从日志中唯一可以明显看出的是您正在尝试将该属性 connectionFactory作为字符串注入。请确保您定义了一个带有 id 的 bean，connectionFactory并且它应该是 type javax.jms.ConnectionFactory，然后使用它来注入。

请发布xml配置。这将有助于进一步调试问题。

编辑：

根据您的输入，

我没有看到<property name="connectionFactory" ...任何地方定义的bean。您还提到它在其他一些环境中工作。请检查哪个 xml 文件包含此 bean 的定义，并确保该文件与您发布的 xml 一起由 spring 加载。
