Spring annotation configuration java.lang.NoClassDefFoundError: org/objectweb/asm/util/TraceClassVisitor
提问by Gleeb
i am trying to run a very simple Spring application with java configuration. i am getting the following exception and i dont understand why. as far as i can tell i have all the required dependencies
我正在尝试使用 java 配置运行一个非常简单的 Spring 应用程序。我收到以下异常，我不明白为什么。据我所知，我拥有所有必需的依赖项
public static void main(String[] args) { System.out.println( "Hello World from main!" ); ApplicationContext ctx = new AnnotationConfigApplicationContext(AppConfig.class); HelloWorld helloWorld = ctx.getBean(HelloWorld.class); System.out.println( helloWorld.getMessage() ); }
public static void main(String[] args) { System.out.println( "Hello World from main!" ); ApplicationContext ctx = new AnnotationConfigApplicationContext(AppConfig.class); HelloWorld helloWorld = ctx.getBean(HelloWorld.class); System.out.println( helloWorld.getMessage() ); }
The exception occures at - AnnotationConfigApplicationContext function call
异常发生在 - AnnotationConfigApplicationContext 函数调用
worth mentioning: I have the following dependency in my POM.XML file.
值得一提的是：我的 POM.XML 文件中有以下依赖项。
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-asm</artifactId> <version>${org.springframework.version}</version> </dependency>
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-asm</artifactId> <version>${org.springframework.version}</version> </dependency>
And the exception:

I actually don't really know what solved the problem, but I did go to some tutorial website that does the same thing and just copied their pom file dependencies. I still don't understand what was missing.
我实际上并不知道是什么解决了问题，但我确实去了一些做同样事情的教程网站，只是复制了他们的 pom 文件依赖项。我仍然不明白缺少什么。
In any case Balint Bako might be right with his answer but i am not sure, i got it solved by the time I got back to StackOverflow.
无论如何，Balint Bako 的回答可能是正确的，但我不确定，当我回到 StackOverflow 时我已经解决了。
Here is the pom file
这是pom文件

As per exception it seems that ASM related jar is missing. You can add asm-all
根据例外情况，似乎缺少与 ASM 相关的 jar。您可以添加 asm-all
<dependency>
<groupId>asm</groupId>
<artifactId>asm-all</artifactId>
<version>2.1</version>
</dependency>

You need spring-core too.
你也需要弹簧芯。
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${org.springframework.version}</version>
</dependency>
