Hello I am new to Spring. This code gives nullpointerexception.
@ContextConfiguration("classpath:org/activiti/spring/test/gal_example/springTest-context.xml")
public class SpringTest{
ProcessEngine processEngine;
@Autowired
ApplicationContext applicationContext;
void initializeProcessEngine() {
System.out.println(" " + applicationContext);
processEngine = applicationContext.getBean(ProcessEngine.class);
System.out.println(" " + processEngine);
}
public static void main(String[] args) {
new SpringTest().initializeProcessEngine();
}
}
but this code works fine
public class SpringTest{
ProcessEngine processEngine;
void initializeProcessEngine() {
ClassPathXmlApplicationContext applicationContext =
new ClassPathXmlApplicationContext("org/activiti/spring/test/gal_example/springTest-context.xml");
System.out.println(" " + applicationContext);
processEngine = applicationContext.getBean(ProcessEngine.class);
System.out.println(" " + processEngine);
}
public static void main(String[] args) {
new SpringTest().initializeProcessEngine();
}
}
what went wrong?Thank you–
