java - Spring构造函数注入(inject)错误

Question

我的应用程序上下文中的 bean 出现以下错误:

Related cause: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'businessLogicContext' d efined in class path resource [activemq-jms-consumer.xml]: Unsatisfied dependency expressed through constructor argument  with index 0 of type [java.lang.String]: Could not convert constructor argument value of type [java.util.ArrayList] to required type [java.lang.String]: Failed to convert value of type [java.util.ArrayList] to required type [java.lang.Stri ng]; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [java.util.ArrayList] to requi red type [java.lang.String]: no matching editors or conversion strategy found

这是我的 bean :

<bean id="businessLogicContext" class="org.springframework.context.support.ClassPathXmlApplicationContext" depends-on="resolveProperty">
         <constructor-arg index="0">
            <list>
               <value>jms-applicationContext.xml</value>
               <value>jms-managerBeanContext.xml</value>
               <value>jms-daoContext.xml</value>
               <value>jms-serviceContext.xml</value>
          </list>       
         </constructor-arg>
    </bean>

我不知道出了什么问题，我在 google 上搜索了如何通过构造函数注入(inject)来注入(inject)字符串数组，我上面的方法似乎没问题。

Answer 1

构造函数需要一个 String 或 String[] 类型，而您正试图注入(inject)一个 ArrayList。
