春天的看点答案

【问题标题】：Aspectj in spring春天的看点
【发布时间】：2009-08-20 06:26:25
【问题描述】：

当我尝试在 spring 中自动连接 aspectj 时出现以下错误

org.xml.sax.SAXParseException: The prefix "aop" for element "aop:aspectj-autoproxy" is not bound.

我的 appContext.xml 条目看起来像 .....

<aop:aspectj-autoproxy/>

<bean id="helloFromAspectJ" class="com.cvs.esps.aspect.logging.TestAspect"/>

.....

有关如何消除此错误的一些帮助.. 不幸的是，站点 http://forum.springsource.org 被网络防火墙阻止.. 任何快速帮助将不胜感激。

如果我添加行，这就是我得到的结果

<bean id="loggerProxy" class="org.springframework.aop.aspectj.annotation.AnnotationAwareAspectJAutoProxyCreator" />

【问题讨论】：

标签： java spring aop aspectj spring-aop

【解决方案1】：

你的标签中有命名空间声明吗？像这样的：

<beans 
xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop"
...>

【讨论】：

springframework.org/schema/aop springframework.org/schema/aop/spring-aop.xsd 我在appContext.xml中添加了这两行
你的意思是你有他们，但仍然没有工作？或者您已经添加了它们并且现在可以添加它们？
请注意 xsi:schemaLocation 项目的顺序确实很重要：每个命名空间 URI 后面都应该跟着它的 XSD 位置。见stackoverflow.com/questions/10062186/…

【解决方案2】：

我遇到了同样的问题，并通过如下安排命名空间和架构位置来解决它：

    <?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:p="http://www.springframework.org/schema/p"
        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-3.0.xsd 
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd 
            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"
        default-destroy-method="destroy"
        default-init-method="afterPropertiesSet"
        default-autowire="byName"
>

请注意，schemalocation 包含两个 uri:s，一个为 xmlns:aop 声明的，另一个为 xsd 文件声明

【解决方案3】：

你可以在你的xml文件中定义AOP的命名空间......

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

复制并粘贴 aop 行

【讨论】：

【解决方案4】：

您有 aop 的命名空间声明，但也缺少 aop 的 xsi:schemaLocation。检查“上下文”模式使用情况（它也出现在 schemaLocation 中）

【讨论】：

【解决方案5】：

请将您的项目转换为aspectj 项目，方法是下载aspectj jar 并将它们复制到相应的eclipse 插件和功能文件夹中。

当你这样做然后重新启动Eclipse，右键单击项目，你会在那里找到一些aspecj Tools选项，然后你可以转换为aspectj，选择源为aspectj。
