问题实例化 bean - 验证错误

Question

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。

问题是在执行这些行时，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

有谁知道问题出在哪里？非常感谢

Bean 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>

类

[...]
package myproject.myclass;
[...]
public class ImageStorageService implements IImageStorageService {
private IRunQueryService    runQueryService;
private IObjectService                              objectService;
private IDataDictionaryService                      dataDictionaryService;
private ImagesUploadStatus                          status;

[...]
public File writePdfFile(String idPlico, String userId) throws Exception {
    return writePdfFile(idPlico, userId, false, 0, 0, 0.0, null);
}

@Override
public File writePdfFile(String idFascicolo, String userId, boolean discardBlankPages, int verticalOffset,
        int horizontalOffset, double threshold, IObject fileInfo) throws Exception {
    File pdfFile;
    [...]
    //pdfFile Elaboration
    [...]
    return pdfFile;
    }
    [...]
}

完整的堆栈跟踪

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