spring - Spring 3.1 基于 Java 的配置——IllegalStateException

Question

我正在学习 Spring 教程，我有以下代码，使用基于 Java 的配置，但它不起作用。在我的类路径中，我有 Spring 3.1 jar，以及 asm-4.0.jar 和 cglib-2.2.2.jar。

MainApp.java：

package com.tutorialspoint;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.*;

public class MainApp {
    public static void main(String[] args) {
        ApplicationContext ctx = new AnnotationConfigApplicationContext(
                HelloWorldConfig.class);
        HelloWorld helloWorld = ctx.getBean(HelloWorld.class);
        helloWorld.setMessage("Hello World!");
        helloWorld.getMessage();
    }
}

HelloWorldConfig.java：

package com.tutorialspoint;

import org.springframework.context.annotation.*;

@Configuration
public class HelloWorldConfig {
    @Bean
    public HelloWorld helloWorld() {
        return new HelloWorld();
    }
}

HelloWorld.java：

package com.tutorialspoint;

public class HelloWorld {
    private String message;

    public void setMessage(String message) {
        this.message = message;
    }

    public void getMessage() {
        System.out.println("Your Message : " + message);
    }
}

错误代码：

当我第一次遇到这个问题时，我正在使用 cglib-2.1_3.jar 和 asm 3.1.jar。在我删除 asm 3.1.jar 并添加 asm-1.5.3.jar 后，它开始工作。

我将 asm jar 文件从 asm-4.0.jar 更改为 asm-3.3.jar，它起作用了。第一个 asm jar 和我使用的 cglib jar 之间一定有冲突。

我使用的是 cglib-2.1_3.jar 和 asm-1.5.3，在使用这个 jar 之后我的程序运行成功。

只需添加此答案，以防有人遇到我遇到的奇怪的极端案例问题。

当 Jar 文件未正确签名时，也会发生这种情况。
