我在Struts应用程序中运行JUNIT测试时收到java.lang.ExceptionInInitializerErr

Question

Error in console for all test cases i am running in STRUTS maven project:
testOverride(com.cisco.mcm.testcase.TestOverrides)  Time elapsed: 3.969 sec  <<< ERROR!
java.lang.ExceptionInInitializerError
    at com.cisco.servicesales.mcm.utils.MCMDataUtil.getDataSource(MCMDataUtil.java:55)
    at com.cisco.servicesales.mcm.utils.MCMDataUtil.getServices(MCMDataUtil.java:45)
    at com.cisco.mcm.dao.AccessManagementDAO.getUserData(AccessManagementDAO.java:83)

MCMDataUtil.java(line 55 ): 
public static DataSource getDataSource(String ConnectionPoolName) {
        System.out.println("Inside getDatasource...1");
        logger.info("Inside getDataSource Method");
        DataSource dataSource = null;   
        System.out.println(":Inside getDatasource...2");
line 55:        ApplicationContext context = SpringSingleton.getContext();
        System.out.println(":Inside getDatasource...3");

由于此错误，Bean 未实例化：

org.apache.maven.surefire.booter.SurefireBooter.main(SurefireBooter.java:980)

你能帮忙摆脱这个错误吗？我已经尝试了很长时间，但找不到任何解决方案。

Answer 1

如果您通过阅读异常的方式，有时它会告诉您有关嵌套异常的信息。如果您不习惯堆栈跟踪，则可能很难阅读这些内容。在这种情况下，根本原因是：

嵌套异常是java.lang.NoClassDefFoundError： oracle/security/pki/OracleWallet

这告诉我们 JVM 找不到要加载oracle.security.pki.OracleWallet，以便创建与数据库的连接。您的类路径上是否有oracle.security.pki.OracleWallet作为另一个 jar 的一部分？
