java - aop :aspectj-autoproxy has worked bad at applicationContext

Question

我是 Spring 的初学者，我在 applicationContext 中使用 aop:aspectj-autoproxy 时遇到问题。这让我很困惑。有目录图像: directory测试代码非常简单，我省略了'import'语句

applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">

    <context:component-scan base-package="schema2.*" />
    <aop:aspectj-autoproxy />

</beans>

Logger.java:

@Aspect
@Component
public class Logger{
    @Before("execution(* schema2.manager.*(..))")
    public void before(JoinPoint joinPoint){
        System.out.println("The Method: " + joinPoint.getSignature().getName());
    }
}

BookShopDao.java:

public interface BookShopDao{
    int findBookPriceByIsbn(String isbn);
    void updateBookStock(String isbn) throws RuntimeException;
    void updateUserAccount(String username, int price);
}

BookShopDaoImpl.java:

@Repository("bookShopDao")
public class BookShopDaoImpl implements BookShopDao{
    @Override
    public int findBookPriceByIsbn(String isbn) {
        return 0;
    }
    @Override
    public void updateBookStock(String isbn) throws RuntimeException {
    }
    @Override
    public void updateUserAccount(String username, int price) {
    }
}

BookShopService.java:

public interface BookShopService {
    void purchase(String book_isbn, String user_name);
}

BookShopServiceImpl.java:

@Service("bookShopService")
public class BookShopServiceImpl implements BookShopService{
    @Override
    public void purchase(String book_isbn, String user_name) {
    }
}

启动.java

public class Start {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        BookShopService server = (BookShopService) context.getBean("bookShopService");
        server.purchase("123", "John");
    }
}

问题:

 Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'bookShopDao' defined in file [C:\Users\qiang\Desktop\spring\spring2\out\production\spring2\schema2\manager\BookShopDaoImpl.class]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: warning no match for this type name: schema2.manager [Xlint:invalidAbsoluteTypeName]
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'bookShopDao' defined in file [C:\Users\qiang\Desktop\spring\spring2\out\production\spring2\schema2\manager\BookShopDaoImpl.class]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: warning no match for this type name: schema2.manager [Xlint:invalidAbsoluteTypeName]

但是如果我删除

aop:aspectj-autoproxy

在applicationContext.xml中，它变得没有问题，并且它已经丢失了@before日志记录

Answer 1

我已经找到答案了，我没有仔细检查...

@Before("execution(* schema2.manager.*(..))") should be changed to @Before("execution(* schema.manager*.*(..))")

我的项目库已导入“aspectj/lib”整个目录，我也不知道为什么会导致问题，这很奇怪。
