Runtime.getRuntime.exec中的ClassPathXmlApplicationContext

我使用spring在eclipse中开发一个web应用来处理依赖注入& maven要部署。 我正在努力使这个小代码工作:

public class MainExternal {


public static void main( String[] args ) throws Exception{


        @SuppressWarnings("resource")           ApplicationContext appContext = new ClassPathXmlApplicationContext( "classpath*:webConfiguration/applicationContext.xml");          ProjectBo projectBo                  = (ProjectBo) appContext.getBean("projectBo");

        System.out.println("-> Im 'in ");

        /************* PRINT OUT  *************/

        Project project = projectBo.findByNameOfStudy("Profiler");


        List<User> listUser = (List<User>) projectBo.findUsers(project);

        for (User myUser : listUser) {

                        System.out.println("User :"+myUser.getFirstname());

        }   
}

当我在eclipse中运行时,它可以工作。

但是,当我从我的网络应用程序中调用它时,它不起作用:

public void throwAnalyse(){

    System.out.println("->I call my function");

    try {

    String[] command= {"java","-cp", "/Users/JP/git/CleanOmicsTracer/target/CleanOmicsTracer.jar", "com.clb.genomic.lyon.external.MainExternal"};

    Process p = Runtime.getRuntime().exec(command);

    ////////////////////////////////////////////
    //test for remote command
    String line;
    BufferedReader bri = new BufferedReader(new InputStreamReader(p.getInputStream()));
    BufferedReader bre = new BufferedReader(new InputStreamReader(p.getErrorStream()));

            while ((line = bri.readLine()) != null) {
                System.out.println(line);
            }
            bri.close();

            while ((line = bre.readLine()) != null) {
                System.out.println(line);
            }
            bre.close();

     p.waitFor();

    } catch (IOException e) {  e.printStackTrace();

    } catch (InterruptedException e) {  e.printStackTrace(); }


    System.out.println("End of programme");
}

当我尝试从控制台执行时:

  

java -cp /Users/JP/git/CleanOmicsTracer/target/CleanOmicsTracer.jar   com.clb.genomic.lyon.external.MainExternal

它不再起作用并抛出:

  

线程“main”中的异常java.lang.NoClassDefFoundError:org / springframework / context / ApplicationContext   引起:java.lang.ClassNotFoundException:org.springframework.context.ApplicationContext       在java.net.URLClassLoader $ 1.run(URLClassLoader.java:202)       at java.security.AccessController.doPrivileged(Native Method)       在java.net.URLClassLoader.findClass(URLClassLoader.java:190)       at java.lang.ClassLoader.loadClass(ClassLoader.java:306)       在sun.misc.Launcher $ AppClassLoader.loadClass(Launcher.java:301)       在java.lang.ClassLoader.loadClass(ClassLoader.java:247)

将Spring jar文件添加到类路径中。对于主jar文件,你可以做

java -cp /path/to/CleanOmicsTracer.jar:spring-full-1.0.1.jar com.clb.genomic.lyon.external.MainExternal

如果您有多个JAR文件,则可以使用类路径通配符

java -cp /path/to/CleanOmicsTracer.jar:lib/* com.clb.genomic.lyon.external.MainExternal
