Spring MVC-配置：找不到元素[default-servlet-handler]的BeanDefinitionParser

Question

i have a problem with Spring MVC.

An exception BeanDefinitionParsingException: Configuration problem: Cannot locate BeanDefinitionParser for element [default-servlet-handler]. If in the file beans.xml i have mvc:default-servlet-handler. If i remove it: no problem.

Answer 1

I'd like to see your xml, but barring that, it sounds like you simply have a classpath issue. Make sure spring-webmvc-VERSION.jar is in your classpath at runtime. If you are using maven, it would look something like this in your pom:

...
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>${your.spring.version}</version>
</dependency>
...

That jar contains the namespace utils, including the proper parser, for the <mvc:default-servlet-handler/> element (amongst others.)
