我的主要课程：

public class SpringDemo {
    public static void main(String[] args) {
        final ApplicationContext applicationContext = new ClassPathXmlApplicationContext("knights-aop.xml");
        final Knight braveKnight = (Knight) applicationContext.getBean("knight");
        braveKnight.embarkOnQuest();

我还试着加上：aopalliance.jar

Answer 1

确保你的pom中有以下内容。xml文件：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aop</artifactId>
    <version>${springframework.version}</version>
</dependency>

根据你的错误堆栈跟踪。

原因：java。lang.NoClassDefFoundError:org/aopalliance/aop/Advice

以下是强制性的

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjrt</artifactId>
    <version>${aspectj.version}</version>
</dependency>
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>${aspectj.version}</version>
</dependency>

当然，您必须为Spring和AOP设置或配置每个版本。

后来我才意识到，您没有使用Maven，即使在Maven Central Repository中，您也可以根据我在上面分享的依赖项下载所需的JAR

Answer 2

与com进行交叉检查。springsource。组织。aopalliance-X.X.X.jar

Answer 3

看起来您只是将aopalliancejar添加到IDE（Eclipse？）的构建类路径中。这就解释了IDE没有显示错误，并接受构建应用程序。但实际上，还必须将其添加到运行类路径中。

根据您使用的IDE，另一个菜单可能允许配置它。但是如果你想在IDE之外运行它，你必须把jar放在你的普通类路径中，或者把它和其他现有的jar放在一起，或者（更好）改变你的用户或系统类路径来包括包含jar的文件夹。

如果你需要，如果我知道你的系统，我可以详细说明...
