java - Spring aop :config

Question

我是 Spring 框架的新手...首先出现了这个错误

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">

现在仍然有错误

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

这是我完整的 xml 文件

请帮忙!我完全不知道。我有一些库文件。我不知道他们具体做什么。是否缺少库？是什么导致了这些错误？我该如何修复它？

Answer 1

使用spring需要大量的库文件。 Aspectjrt、Aspectj-weaver、aop-alliance 是其中一些，我们没有将其作为 Spring 依赖 jar 文件获得。我们已经下载并添加到类路径以成功运行基于 spring 的应用程序。
