Eclipse中的Spring Classpath问题

Question

I'm trying to set up a Spring application to run in eclipse for the first time. I'm running it at as a standalone java application. The app builds without any errors but when I go to execute it, I get a ClassNotFoundException with the following stack trace:

DataLoadService [Java Application]

It's happening on this line of code:

ApplicationContext context=new ClassPathXmlApplicationContext("classpath:spring.xml");

spring.xml gets moved into the class/ folder during the build process so I tried adding the class folder to the launch configuration (see screenshot).

I'm working with eclipse 3.7.2 and spring 3.1.1

Answer 1

Check the spring libs. This issue is about the project build path and configuration.

Answer 2

I don't know spring but the following is suspicious:

ApplicationContext context=new ClassPathXmlApplicationContext("classpath:spring.xml");

Perhaps it should be

ApplicationContext context=new ClassPathXmlApplicationContext("spring.xml");

For example, in this question the usage is

ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

Unless your file is actually called classpath:spring.xml , not sprint.xml , but I doubt that.
