STS Spring Project: Why is that HelloWorld example not working?
提问by achingfingers
I am new to Spring and currently trying the following Hello World examplefrom the book ProSpring3:
我是 Spring 的新手，目前正在尝试ProSpring3 一书中的以下Hello World 示例：
package com.tutorials.prospring3.ch2;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class HelloWorldSpringDI {
public static void main(String[] args) {
// Initialize Spring ApplicationContext
ApplicationContext ctx = new ClassPathXmlApplicationContext(
"META-INF/spring/app-context.xml");
MessageRenderer mr = ctx.getBean("renderer", MessageRenderer.class);
mr.render();
}
}
The ClassPathXmlApplicationContext instantiation is marked as the following error: "The constructor ClassPathXmlApplicationContext(String) refers to the missing type BeansException"
ClassPathXmlApplicationContext 实例化被标记为以下错误：“构造函数 ClassPathXmlApplicationContext(String) 引用了缺少的类型 BeansException”
In addiation, when running the application the IDE displays a build path problem:"Archive for required library: 'C:/Users/Admin/.m2/repository/org/springframework/spring-beans/3.0.6.RELEASE/spring-beans-3.0.6.RELEASE.jar' in project 'ch2' cannot be read or is not a valid ZIP file"
此外，在运行应用程序时，IDE 显示构建路径问题：“所需库的存档：'C:/Users/Admin/.m2/repository/org/springframework/spring-beans/3.0.6.RELEASE/spring-项目 'ch2' 中的 beans-3.0.6.RELEASE.jar' 无法读取或不是有效的 ZIP 文件"
As the spring-beans.jar (to which the BeansException class belongs) is part of my Maven Dependenciesi wonder how that could happen.
由于 spring-beans.jar（BeansException 类所属）是我的Maven 依赖项的一部分，我想知道这是怎么发生的。
Has anyone a suggestion how to solve that problem?
有没有人建议如何解决这个问题？
Thanks in advance!
提前致谢！

try to open the archive C:/Users/Admin/.m2/repository/org/springframework/spring-beans/3.0.6.RELEASE/spring-beans-3.0.6.RELEASE.jarwith an application like WinZip. If that application indicates that the archive is corrupted as well, you should delete it and try again. (delete the entire C:/Users/Admin/.m2/repository/org/springframework/spring-beans/3.0.6.RELEASEdirectory and all its contents).
On the next build of your project, the archive will be downloaded again. If it still does not work and you are connecting to a local repository, you should contact the administrator.
尝试C:/Users/Admin/.m2/repository/org/springframework/spring-beans/3.0.6.RELEASE/spring-beans-3.0.6.RELEASE.jar使用 WinZip 等应用程序打开存档。如果该应用程序表明存档也已损坏，则应将其删除并重试。（删除整个C:/Users/Admin/.m2/repository/org/springframework/spring-beans/3.0.6.RELEASE目录及其所有内容）。在项目的下一次构建中，将再次下载存档。如果它仍然不起作用并且您正在连接到本地存储库，您应该联系管理员。

Look like the dependency is missing from your project's classpath. To resolve it
看起来您的项目的类路径中缺少依赖项。解决它
Right click on your project
Navigate to **Maven**
Click on **Update project**
If it does not resolve this problem then
如果它不能解决这个问题，那么
Go to the path
去路径
C:/Users/Admin/.m2/repository/org/springframework/ and delete the folder named as
spring-beans
C:/Users/Admin/.m2/repository/org/springframework/ 并删除名为的文件夹
spring-beans
Now again Right click on your project
Navigate to **Maven**
Click on **Update project**
It will update/add the orphan/missing dependency of your project
它将更新/添加项目的孤立/缺失依赖项

I konw your problem have out of date, i just want to help someone who gets the same problem, as i got the same problem and finished it.It's easy,just add the org.springframework.beans.jar to your project.
我知道你的问题已经过时了，我只是想帮助遇到同样问题的人，因为我遇到了同样的问题并完成了它。很简单，只需将 org.springframework.beans.jar 添加到您的项目中。

Two causes:
两个原因：
- The issue could be with the corrupted Spring JARs . Remove the existing Spring dependancies Add dependencies from : http://mvnrepository.com/artifact/org.springframework/spring-beans/5.0.0.M5It ll solve the issue.
- 问题可能与损坏的 Spring JAR 有关。删除现有的 Spring 依赖项从以下位置添加依赖项：http: //mvnrepository.com/artifact/org.springframework/spring-beans/5.0.0.M5它将解决问题。
2.The indirect dependancies for beans are not sufficiently added.
2.对bean的间接依赖添加不充分。
Add the dependancies .
添加依赖项。

Go to :C:\Users(user_name(or)admin_name).m2\repository\org\springframework
转到 :C:\Users(user_name(or)admin_name).m2\repository\org\springframework
Now, delete spring-beans and spring-expression folder.
现在，删除 spring-beans 和 spring-expression 文件夹。
Go to :Eclipse and then update the project by right clicking on the project maven>update project. Eclipse will download the required files.ISSUE SOLVED :-)
转到：Eclipse，然后通过右键单击项目 maven>update project 来更新项目。Eclipse 将下载所需的文件。问题已解决 :-)

I had the same issue when I was working with 4.2.2.RELEASE version of Spring, once I changed it to 4.2.0.RELEASE, the error dispeared. I hope this can help in your case too.
当我使用 4.2.2.RELEASE 版本的 Spring 时，我遇到了同样的问题，一旦我将其更改为 4.2.0.RELEASE，错误就会消失。我希望这对你的情况也有帮助。
