spring数组注入问题

Question

[code="java"]
package com.spdb.conf;

public class ChangeRptConf {
private String[] orgIdArray;

public String[] getOrgIdArray() {
    return orgIdArray;
}

public void setOrgIdArray(String[] orgIdArray) {
    this.orgIdArray = orgIdArray;
}

}

[/code]

[code="xml"]

[/code]

测试代码
[code="java"]
ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");

    ChangeRptConf conf = (ChangeRptConf) ctx.getBean("changeRptConfBean");

    String[] x = conf.getOrgIdArray();
    for (int i = 0; i < x.length; i++) {
        System.out.println(x[i]);
    }

[/code]

具体报错：
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'changeRptConfBean' defined in class path resource [applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert property value of type [java.util.ArrayList] to required type [java.lang.String[]] for property 'orgIdArray'; nested exception is java.lang.IllegalArgumentException: Original must not be null

难道是bean配置有问题吗？
