春天的Aspectj

Question

当我尝试在春天自动连接方面时，我收到以下错误

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"/>

.....

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

---

如果我添加该行，我会得到以下结果

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

Answer 1

您的标签中有名称空间声明吗？像这样的事情：

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

Answer 2

我遇到了同样的问题，并通过如下安排命名空间和 schemalocation 解决了它：

    <?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 uri:s，为 xmlns:aop 声明的一个和为 xsd 文件

HTH声明的一个

Answer 3

您可以在 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

Answer 4

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

Answer 5

请下载 aspectj jar 并将其相应地复制到 eclipse 插件和功能文件夹中，将您的项目转换为 aspectj 项目。

当你这样做时，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。
