java - 不使用 Spring 时出现 Spring 异常

Question

我在让 CDI 与 JAX-WS Web 服务实现配合使用时遇到问题。然而，在尝试调试此问题时，我在日志中看到一个我无法理解的异常。日志，异常(exception)情况是(第 5 行以“[警告]”开头:

Launching defaultServer (WebSphere Application Server 8.5.5.6/wlp-1.0.9.cl50620150610-1749) on Java HotSpot(TM) 64-Bit Server VM, version 1.7.0_79-b15 (en_US)

我很困惑为什么会加载任何 Spring 类。我根本没有使用Spring。这是 JAX-WS Web 服务的纯 Java 7 实现。以下是我的实现类:

package path.not.important.external.service;

import java.util.List;

import javax.inject.Inject;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.xml.soap.SOAPException;

import org.apache.commons.collections4.CollectionUtils;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

import path.not.important.external.domain.DemographicBean;
import path.not.important.external.domain.ErrorInfo;
import path.not.important.external.domain.SubmissionValidationResults;
import path.not.important.internal.client.FileSubmissionServiceHandler;
import path.not.important.rules.submission.BRSubmissionService;
import path.not.important.internal.SubmissionFormData;
import path.not.important.plugin.IResult;
import path.not.important.plugin.SubmissionResult;

@WebService(serviceName="eNC3BusinessWebService")
public class eNC3BusinessWebServiceImpl
{

    @WebMethod
    public SubmissionValidationResults xmlValidation(String xml, String submissionType, String schemaVersion)
            throws SOAPException
    {
        logger.info("--- Validating Incomming Form XML ---");

        logger.info("Received Payload: XML [" + xml + "]");
        logger.info("SubmissionType [" + submissionType + "]");
        logger.info("SchemaVersion [" + schemaVersion + "]");

        return results;
    }

    @WebMethod
    public SubmissionValidationResults flatFileValidation(String filename, byte[] file) throws SOAPException
    {
        logger.info("--- Converting and Validating Incomming Form Flat File ---");

        logger.info("Validating flat file: " + filename);
        logger.info("file size: " + file.length);
        logger.info("file: " + file.toString());

        return results;
    }

    @WebMethod
    public String finalNC3FormSubmission(DemographicBean demographicData, List<SubmissionFormData> nc3,
            List<SubmissionFormData> irsW2, List<SubmissionFormData> irs1099) throws SOAPException
    {
        logger.info("Executing final submission of website form data...");

        return messageID;
    }

    @Inject
    private FileSubmissionServiceHandler fileSubmissionServiceHandler;

    @Inject
    private BRSubmissionService brSubmissionService;

    public static final Logger logger = LogManager.getLogger(eNC3BusinessWebServiceImpl.class);
}

我不知道我的 CDI 问题和此问题是否相关，但我正在尝试消除导致该问题的任何其他原因。我的 CDI 问题记录如下: JAX-WS and CDI not working together on WAS Liberty Profile 8.5.5.6

Answer 1

好的，我终于找出了问题的原因。这也回答了我的另一个问题。

CDI 正在加载名为 BRSubmissionService 的对象。 CDI 加载被 spring 异常中断。并且由于 CDI 无法完成，因此剩余的 CDI 注入(inject)不会发生，并且我的 FileSubmissionService 对象未加载，导致我的空指针异常。

解决方案是修复 BRSubmissionService 对象内的 spring 错误，该对象位于另一个 jar 中，不幸的是我从另一个开发人员那里继承了该错误。这就是生活。
