这是问题的延续
Spring MVC @PathVariable被截断
Spring论坛声明它已经固定(3.2版本)作为ContentNegotiationManager的一部分。请看下面的链接。
https://jira.springsource.org/browse/SPR-6164
https://jira.springsource.org/browse/SPR-7632
在我的应用程序中,带有。com的requestParameter被截断了。
谁能告诉我如何使用这个新功能?如何在xml中配置它?

Spring MVC @PathVariable带点(.)会被截断
如果您正在使用Spring 3.2+,那么下面的解决方案将有所帮助。这将处理所有的url,所以肯定比在请求URI映射中应用regex模式更好。喜欢/ somepath /{变量:。+}
在xml文件中定义一个bean
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
<property name="useSuffixPatternMatch" value="false"/>
<property name="useRegisteredSuffixPatternMatch" value="true"/>
</bean>
标志的用法可以在文档中找到。我把剪报解释一下
解释useRegisteredSuffixPatternMatch据说可以解决这个问题。来自类中的java文档
If enabled, a controller method mapped to "/users" also matches to
"/users.json" assuming ".json" is a file extension registered with the
provided {@link #setContentNegotiationManager(ContentNegotiationManager)
contentNegotiationManager}. This can be useful for allowing only specific
URL extensions to be used as well as in cases where a "." in the URL path
can lead to ambiguous interpretation of path variable content, (e.g. given
"/users/{user}" and incoming URLs such as "/users/john.j.joe" and
"/users/john.j.joe.json").
如果您正在使用Spring 3.2。x和<mvc:annotation-driven />,创建这个小BeanPostProcessor:
package spring;
public final class DoNotTruncateMyUrls implements BeanPostProcessor {
@Override
public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
if (bean instanceof RequestMappingHandlerMapping) {
((RequestMappingHandlerMapping)bean).setUseSuffixPatternMatch(false);
}
return bean;
}
@Override
public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
return bean;
}
}
然后把这个放在你的MVC配置xml中:
<bean class="spring.DoNotTruncateMyUrls" />
