Spring aop:config

Question

我刚开始使用 Spring 框架...首先出现这个错误

The prefix aop for element aop config is not bound

然后我将以下内容添加到 Spring.xml

<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:tx="http://www.springframework.org/schema/tx"
    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/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

现在还是有错误

Error occured processing XML 'org/springframework/aop/aspectj/AspectJMethodBeforeAdvice'

这是我的完整 xml 文件

请帮忙！我完全不知道。我有几个库文件。我不知道他们到底是做什么的。是否缺少图书馆？是什么导致了这些错误？我该如何解决？

Answer 1

(...) 是为切入点指定参数（零个或多个）的不正确方式。尝试在切入点表达式中用 (..) 替换。

Answer 2

使用spring需要很多库文件。 Aspectjrt、Aspectj-weaver、aop-alliance 是一些，我们没有得到 spring 依赖 jar 文件。我们已经成功下载并添加到基于运行 spring 的应用程序的类路径中。
