《Spring实战》-- 'cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element' 错误的解决办法
在Eclipse中新建了一个maven项目学习Spring,在 service.xml 中配置 Spring,想要学习‘面向切面的Spring’,service.xml 内容如下:
<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/shema/aop"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:c="http://www.springframework.org/schema/c"
xsi:schemaLocation="
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
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
">
<bean id="audience" class="proxy.Audience" />
<aop:config>
<aop:aspect ref="audience">
<aop:around
pointcut="execution(** concert.Performance.perform(..))"
method="watchPerformance(ProceedingJoinPoint)" />
</aop:aspect>
</aop:config>
</beans>
结果写 <aop: ** > 的时候,没有代码提示,而且总是出现错误提示:
Multiple annotations found at this line:
- cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element
'aop:config'.
如图所示:
网上搜索解决方案,看到类似的问题是 xsi:schemaLocation 中的 url 没有配置好。思来想去,可能是因为自己在 <beans > 中的url没有写正确,就Ctrl+F 搜索‘http://www.springframework.org/schema/’,匹配的字符串就会背景高亮显示。发现果然是因为 “xmlns:aop="http://www.springframework.org/shema/aop" 没有写正确 --- shema 应该是 schema。
改正以后就好了。ヾ(@▽@)ノ
