项目部署 - 解决报错：The matching wildcar

2020-09-17  本文已影响0人  程序猿蛋蛋哥

传统SpringMVC框架开发的后端应用，部署服务器时，报错，服务启动不起来。

主要错误信息摘录如下：

ERROR [org.springframework.web.servlet.DispatcherServlet] - Context initialization failed
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 33 in XML document from ServletContext resource [/WEB-INF/config/spring-mvc.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 33; columnNumber: 29; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'mvc:annotation-driven'.
...
Caused by: org.xml.sax.SAXParseException; lineNumber: 33; columnNumber: 29; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'mvc:annotation-driven'.
...

错误解析

主要错误信息为：The matching wildcard is strict, but no declaration can be found for element 'mvc:annotation-driven'.

意思是没有声明<mvc:annotation-driven>的命名空间。

但是，查了SpringMVC配置文件，有声明<mvc>相关的命名空间。

其实问题的根源是：

例如：

<?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:mvc="http://www.springframework.org/schema/mvc"  
    xsi:schemaLocation="http://www.springframework.org/schema/beans    
                        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd    
                        http://www.springframework.org/schema/context    
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd    
                        http://www.springframework.org/schema/mvc    
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
</beans>

解决方法

配置文件中声明的各命名空间版本保持一致，且与使用的Spring jar包版本一致。

<?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:mvc="http://www.springframework.org/schema/mvc"  
    xsi:schemaLocation="http://www.springframework.org/schema/beans    
                        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd    
                        http://www.springframework.org/schema/context    
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd    
                        http://www.springframework.org/schema/mvc    
                        http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">
                        注意：上面版本改为3.1
</beans>
