Question

我使用的是Intellij，我的源类是main.com.coding，我的资源文件是main.com.testing。我把spring.xml文件放在我的资源文件中。

我的测试类在test.com.coding中，我的测试资源文件是test.com.testing。

我尝试在我的主要课程中执行这样的代码：

 public static void main(String[] args) throws Exception {
    ApplicationContext context = new ClassPathXmlApplicationContext(args[0]);

在我的单元测试中，当我尝试测试方法时，我尝试了这个并且args [0]是我的弹簧文件：

@Test
public void testMain() throws Exception {
    DataMain data = new DataMain();
    String[] a = {"/config.context.xml","sample.text","output.text" };
    data.main(a);
}

这就是config.context.xml里面的内容：

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE beans PUBLIC  "-//SPRING//DTD BEAN//EN"
        "http://www.springframework.org/dtd/spring-beans.dtd">
 <beans>

另外，我的lib路径中有spirng.jar。我想知道他们找不到我的文件有什么问题。我的事件试图通过主要的方法传递绝对路径，如：

public static void main(String[] args) throws Exception {
    String absPath = //absolute path of spring file for args[0]
    ApplicationContext context = new ClassPathXmlApplicationContext(absPath );

这是我得到的错误：

添加commons-logging.jar，您的错误就会得到解决。

另外我建议您使用maven，因为它会在内部解析所有依赖项。

ClassPathXmlApplicationContext的NoClassDefFoundError？
