Java 无法加载配置类

下面是关于如何使用Spring的教程，根据提供的示例，我得到以下异常：

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);
    }
}

MainApp.java

package com.tutorialspoint;

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

public class MainApp {
    public static void main(String[] args) {
        @SuppressWarnings("resource")
        ApplicationContext ctx = new AnnotationConfigApplicationContext(
                HelloWorldConfig.class);

        HelloWorld helloWorld = ctx.getBean(HelloWorld.class);

        helloWorld.setMessage("Hello World!");
        helloWorld.getMessage();
    }
}

另外，我说“尽管我尝试了这个解决方案，但它没有起作用”，我的意思是返回了完全相同的错误。

因此，我想说，您提到的另一个解决方案有不同的问题。 即使最后显示的异常与您的相同。 但正如您在stacktrace中看到的，源代码是SecurityException

*无法加载配置类*-错误是后遗症

我想您的项目中的代码签名有问题 或者，由于字节码操作，签名被破坏

附言： 有时，在项目中引用SignedLib和UnsignedLib时，也会发生这种情况。

---

在这种情况下，请从已签名的LIB中删除签名。

运行此项目所需的所有JAR： 1 org.springframework.core-3.0.1.RELEASE-A.jar 2 spring-context-3.0.4.RELEASE.jar 3 org.springframework.beans-3.0.1.RELEASE-A.jar 4 commons-logging-1.1.1.jar 5 asm-3.3.1.jar 6 cglib-2.2.2.jar

要获取这些JAR，可以直接将下载的JAR添加到项目中，或者在pom.xml中提供以下依赖项，以便为您自动下载它们

    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>3.0.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>3.0.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.1.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>3.0.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>cglib</groupId>
            <artifactId>cglib</artifactId>
            <version>2.2.2</version>
        </dependency>
    </dependencies>

如果maven settings.xml文件尚未存在，请将其添加到maven settings.xml文件中：

    <profiles>
        <profile>
            <id>SPRINGLEARN</id>
            <activation>
                <jdk>1.8</jdk>
            </activation>
            <repositories>
                <repository>
                    <id>thirdPartyRepo</id>
                    <name>Third party repository</name>
                    <url>https://repo.spring.io/libs-release/</url>
                    <layout>default</layout>
                    <snapshotPolicy>always</snapshotPolicy>
                </repository>
            </repositories>
            <pluginRepositories>
                <pluginRepository>
                    <id>thirdPartyPluginRepo</id>
                    <name>Third party plugin repository</name>
                    <url>https://repo.spring.io/libs-release/</url>
                    <layout>default</layout>
                    <snapshotPolicy>always</snapshotPolicy>
                </pluginRepository>
            </pluginRepositories>
        </profile>
    </profiles>

在此之后，只需运行您的项目。 -右键单击项目->运行方式->Maven clean -右键单击项目->运行方式->Maven安装

---

-右键单击您的项目->运行方式->Java应用程序

您使用的Java版本是什么？当使用诸如ASM.Spring版本之类的字节码操纵库时，这可能会有所不同？他们现在正在对一些字节码操作进行着色处理。@drembert JavaSE-1。7@chrylis很抱歉，这是Spring工具套件版本，我使用的IDE是为了使用Spring。Spring版本是4.0.2。如何从已签名的libs中删除签名？使用任何Zip Archiver打开Jar，编辑Manifest file Meta Inf文件夹，并删除Java类具有签名信息的所有行。。。此外，您还可以删除Meta Inf文件夹中的*.rsa文件。签名信息是什么样子的？这样地？Name:org/springframework/context/weaving/AspectJWeavingEnabler.class SHA1摘要：l50iHSxP9TMDMpK9ncKZNZuDX4M=是，删除所有这些条目以删除签名信息。同时删除meta-inf目录中的sf和dsa文件。我已经这样做了，但是系统现在声明无法解析导入org.springframework.context。
