java - 使用 Spring 从命令行运行 Java cron 时出错

Question

当从 eclipse 作为独立应用程序运行时，这一切都有效。

我的Java主要方法:

public static void main(String[] args) throws MessagingException, IOException, RequestErrorFault, UnexpectedErrorFault, ServerErrorFault {
        ApplicationContext context = new FileSystemXmlApplicationContext("src" + File.separator + "main" + File.separator + "webapp" + File.separator + "WEB-INF" + File.separator + "spring" + File.separator + "appServlet" + File.separator + "cron-context.xml");

        CheckStatus checkStatus = context.getBean(CheckStatus.class);


        List<Integer> requestIds = checkStatus.getRequests(); 
        checkStatus.processRequests(requestIds);
    }

输出:

java -cp /html/myProj/API/target/classes:/html/myProj/API/target/API-1.0.0-BUILD-SNAPSHOT/WEB-INF/lib  com.api.spring.management.CheckStatus
Error: A JNI error has occurred, please check your installation and try again

我已传入类路径上的 lib 文件夹，其中所有 spring jar 都存在。我也尝试通过 mvnexec:java 运行它，但似乎都不起作用。

除此之外:

Try with java -cp "/html/myProj/API/target/classes:/html/myProj/API/target/API-1.0.0-BUILD-SNAPSHO‌​T/WEB-INF/lib/" com.api.spring.management.CheckStatus. (note the / at the end) – Tunaki

事实证明，我的一个依赖项没有设置为在 war 中导出，所以在我修复后，一切都正常了。
