我想从我的项目中启动一些外部java类或jar。但我想从我的网络应用程序项目中使用Bo类。我想在我的主类中加载它们但我得到一些奇怪的错误。
我运行一个干净的安装来获得一个.war和一个带有maven的.jar。直到一切正常。
为了获得带有依赖关系的.jar，我使用：
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>com.clb.genomic.lyon.external.MainExternal</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-my-jar-with-dependencies</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
在我的战争中，我有一个通过Runtime.getRuntime.exec调用主类的bean。
public void throwAnalyse(){
System.out.println("->I call my function");
try {
String[] command= {"java","-jar", "/Users/JP/git/CleanOmicsTracer/target/CleanOmicsTracer-jar-with-dependencies.jar"};
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");
}
我的主要课程：
public class MainExternal {
public static void main( String[] args ) throws Exception{
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());
}
}
这是我得到的错误......
