Question

我遇到了一个spring bean配置问题（r3.2.2）。应用程序在weblogic 10.3.5上运行，在项目启动时，我在下面的stacktrace中得到以下内容。在阅读其他一些帖子时，必须有一个数组构造函数。

任何人都知道为什么我会得到这个堆栈跟踪？

谢谢

我的xml配置：

   <!-- custom marshaller to make union of 2 interfaces -->
    <bean id="union.marshaller" class="be.test.jaxb.MergedJaxb2Marshaller">
        <constructor-arg>
            <array>
                <ref bean="m1.marshaller"/>
                <ref bean="m2.marshaller"/>
                <ref bean="m3.marshaller"/>
            </array>
        </constructor-arg>
    </bean>

我的课程：

package be.test.jaxb;

import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import org.springframework.util.Assert;

public class MergedJaxb2Marshaller
  extends Jaxb2Marshaller
{
  private static final String COLON = ":";

  public MergedJaxb2Marshaller(Jaxb2Marshaller... marshallers)
  {
    Assert.notNull(marshallers, "marshallers not valid [null]");
    setContextPath(toMergedContextPath(marshallers));
  }

  private String toMergedContextPath(Jaxb2Marshaller... marshallers)
  {
    Assert.notNull(marshallers, "marshallers not valid [null]");
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < marshallers.length; i++) {
      if (i == 0) {
        sb.append(marshallers[i].getContextPath());
      } else {
        sb.append(":").append(marshallers[i].getContextPath());
      }
    }
    return sb.toString();
  }
}

我在发布此问题时已尝试使用列表（Declaring an array of objects in a Spring bean context）。但后来我得到以下内容：

引起：java.lang.NoSuchMethodError：org.springframework.util.xml.DomUtils.getChildElements（Lorg / w3c / dom / Element;）Ljava / util / List; 在org.springframework.ws.config.InterceptorsBeanDefinitionParser.parse（InterceptorsBeanDefinitionParser.java:52）
