（TypeConverterDelegate.java:529は） - [java.util.ArrayListの]コレクション型のコピーを作成できません -

Question

-であるように、元のコレクションを注入し、私はプログラムを持っている：

public static void main(String[] args) 
    { 
     ApplicationContext ctx = ServiceLocator.getApplicationContext(); <-- error 
.......} 

それは、以下のエラーメッセージがあります。私は[DEBUG]でJAVAから来ているようなこのエラーを取り除きたい。しかし、プログラムは引き続き実行できます。私はgoogleで検索しましたが、運はありません。私はまた、コードがどこに間違っているのか分からない。これを解決することは可能ですか？

com.xxxx.ServiceLocator.getApplicationContextで

（ServiceLocator.java:24）

package com.xxxx; 
     import org.springframework.beans.factory.BeanFactory; 
     import org.springframework.beans.factory.access.BeanFactoryLocator; 
     import org.springframework.beans.factory.access.BeanFactoryReference; 
     import org.springframework.context.ApplicationContext; 
     import org.springframework.context.access.ContextSingletonBeanFactoryLocator; 
     public class ServiceLocator { 
      private static ApplicationContext applicationContext; 

      protected ServiceLocator() { 
      } 

      public static ApplicationContext getApplicationContext() { 
       if (applicationContext == null) { 

        BeanFactoryLocator locator = ContextSingletonBeanFactoryLocator.getInstance("ApplicationContext.xml"); 
        BeanFactoryReference bfr = locator.useBeanFactory("applicationContext"); 
        BeanFactory factory = bfr.getFactory(); 
        applicationContext = (ApplicationContext) factory; 
       } 
       return applicationContext; 
      } 

     } 

applicationContext.xmlを

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"> 

    <bean id="applicationContext" 
     class="org.springframework.context.support.ClassPathXmlApplicationContext"> 
     <constructor-arg> 
      <list> 
       <value>ApplicationContext-properties.xml</value>

</beans>  

Answer 1

あなたのBean定義が正しくありません。

置き換える：

<bean id="applicationContext" class="org.springframework.context.support.ClassPathXmlApplicationContext"> 
    <constructor-arg value="ApplicationContext-properties.xml" /> 
    <constructor-arg value="ApplicationContext-log4j.xml" /> 
    <constructor-arg value="ApplicationContext-datasource.xml" /> 
</bean> 

と

<bean id="applicationContext" class="org.springframework.context.support.ClassPathXmlApplicationContext"> 
    <constructor-arg> 
     <list> 
      <value>ApplicationContext-properties.xml</value> 
      <value>ApplicationContext-log4j.xml</value> 
      <value>ApplicationContext-datasource.xml</value> 
     </list> 
    </constructor-arg> 
</bean>
