Spring can't find configuration in path
提问by Arturas M
well I'm runnning this code and it cant' find the springconfig4.xml file:
好吧，我正在运行此代码，但找不到 springconfig4.xml 文件：
package com.nortal.pirs.test.independant;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test4 {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("/com/nortal/pirs/beans/springconfig4.xml");
BeanFactory factory = context;
Test3 instance = (Test3) factory.getBean("Test3");
instance.run();
}
}
I mean I was kind of expecting it not to work, because in Java it never works when you try to use a path that is not in your current package. However as many Spring tutorials I've seen, they all show this way of specifying the configuration file.
我的意思是我有点期待它不起作用，因为在 Java 中，当您尝试使用不在当前包中的路径时，它永远不会起作用。然而，正如我所看到的许多 Spring 教程，它们都展示了这种指定配置文件的方式。
Now my springconfig4.xml is in my applications' src/com/nortal/pirs/beans folder. So how do I specify it so that it can be found here?
现在我的 springconfig4.xml 位于我的应用程序的 src/com/nortal/pirs/beans 文件夹中。那么我如何指定它以便可以在这里找到它？
The current Test4 class is located in src/com/nortal/pirs/test/independant folder.
当前的 Test4 类位于 src/com/nortal/pirs/test/independant 文件夹中。

Or is the problem somewhere else maybe?
或者可能是其他地方的问题？

Exception says it is not finding a class, not Spring context xml
异常表示它没有找到一个类，而不是 Spring 上下文 xml

please add asm dependency
请添加 asm 依赖项
<dependency>
<groupId>org.springframework</groupId>
<artifactId>org.springframework.asm</artifactId>
<version>3.1.0.RELEASE</version>
</dependency>

Your stacktrace points this:
您的堆栈跟踪指出：
java.lang.ClassNotFoundException: org.springframework.asm.ClassVisitor
You need to download the spring-asm-3.1.2.RELEASE.jarfile from the maven repo(supposing that you are using spring 3.1.2) or if you are using maven, edit your pom.xmlfile and add the next lines:
您需要从maven 存储库下载spring-asm-3.1.2.RELEASE.jar文件（假设您使用的是 spring 3.1.2），或者如果您使用的是 maven，请编辑您的文件并添加下一行：pom.xml
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-asm</artifactId>
<version>3.1.2.RELEASE</version>
</dependency>
Also, this line:
此外，这一行：
ApplicationContext context = new ClassPathXmlApplicationContext("/com/nortal/pirs/beans/springconfig4.xml");
Has an error, the path must not start with a trailing /., so the path to the file becomes: "com/nortal/pirs/beans/springconfig4.xml".
有错误，路径不能以/.开头，所以文件路径变成："com/nortal/pirs/beans/springconfig4.xml".
The ClassPathResource javadocstates that it will be removed anyways:
在使用ClassPathResource的javadoc说，它会被删除反正：
Create a new ClassPathResource for ClassLoader usage. A leading slash will be removed, as the ClassLoader resource access methods will not accept it.
为 ClassLoader 使用创建一个新的 ClassPathResource。前导斜杠将被删除，因为 ClassLoader 资源访问方法将不接受它。

Just add the spring-asm-3.1.2.RELEASE.jar file. Place it in your lib folder.
只需添加 spring-asm-3.1.2.RELEASE.jar 文件。把它放在你的 lib 文件夹中。
回答by vikky
For the above problem as mentioned above these jars are missing namely 1.org.springframework.asm-3.0.1.RELEASE-A.jar 2.org.springframework.expression-3.0.1.RELEASE-A.jar or Add all the core Jars of Springso that any new programmer can Run all basic level programs.
对于上面提到的上述问题，这些 jar 丢失即 1.org.springframework.asm-3.0.1.RELEASE-A.jar 2.org.springframework.expression-3.0.1.RELEASE-A.jar 或添加所有Spring 的核心 Jars以便任何新程序员都可以运行所有基本级别的程序。
There is no need of below line in your program. insted of that you can use contextinsted of factoryin the above program.
您的程序中不需要以下行。insted的，你可以使用上下文insted的的工厂在上面的程序。
BeanFactory factory = context
BeanFactory 工厂 = 上下文
We usually use ApplicationContextinsted of BeanFactory. Even if you use BeanFactory there will be no effect for the program.
我们通常使用BeanFactory 的ApplicationContext插入。即使您使用 BeanFactory 也不会对程序产生任何影响。
