最后，我在Spring Docs中找到了解决方案:

要完全禁用文件扩展名，您必须同时设置以下两项: useSuffixPatternMatching(false)，参见PathMatchConfigurer favorpatheextension (false)，参见ContentNegotiationConfigurer

将此添加到我的WebMvcConfigurerAdapter实现解决了这个问题:

@Override
public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
    configurer.favorPathExtension(false);
}

@Override
public void configurePathMatch(PathMatchConfigurer matcher) {
    matcher.setUseSuffixPatternMatch(false);
}

据我所知，这个问题只出现在请求映射结束时的路径变量。

我们可以通过在requestmapping中定义regex插件来解决这个问题。

 /somepath/{variable:.+}

/ somepath /{变量:。+}适用于Java requestMapping标签。

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" />

下面是一种完全依赖java配置的方法:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;

@Configuration
public class MvcConfig extends WebMvcConfigurationSupport{

    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping handlerMapping = super.requestMappingHandlerMapping();
        handlerMapping.setUseSuffixPatternMatch(false);
        handlerMapping.setUseTrailingSlashMatch(false);
        return handlerMapping;
    }
}

在spring 4.2的路径名中包含电子邮件地址的完整解决方案是

<bean id="contentNegotiationManager"
    class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
    <property name="favorPathExtension" value="false" />
    <property name="favorParameter" value="true" />
    <property name="mediaTypes">
        <value>
            json=application/json
            xml=application/xml
        </value>
    </property>
</bean>
<mvc:annotation-driven
    content-negotiation-manager="contentNegotiationManager">
    <mvc:path-matching suffix-pattern="false" registered-suffixes-only="true" />
</mvc:annotation-driven>

将其添加到应用程序xml中
