我有以下问题：我有一个 bean（名为 ImageStorageService），我想使用以下代码在 servlet 中实例化该 bean

WebApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(httpSession
            .getServletContext());
IImageStorageService dataService = (IImageStorageService) context
            .getBean("ImageStorageService");

显然 bean 类实现了 IImageStorageService。

问题是当执行这些行时，会抛出以下错误：

java.lang.VerifyError: (class: myproject/myclass/ImageStorageService, method: writePdfFile signature: (Ljava/lang/String;Ljava/lang/String;Lmyproject/myobjects/IObject;)Ljava/io/File;) Call to wrong initialization method

有谁知道是哪个问题？非常感谢

豆声明

<bean id="ImageStorageService" scope="session"
    destroy-method="clean"
    class="myproject.myclass.ImageStorageService">
    <property name="objectService" ref="SuperUserObjectService" />
    <property name="dataDictionaryService" ref="DataDictionaryService" />
    <property name="runQueryService" ref="RunQueryService" />
    <property name="status" ref="ImagesUploadStatus" />
</bean>

显然不是一个长期的解决方案，但您可以通过添加-noverify到命令行来绕过类验证。您可能还想尝试进行干净的构建。
