对我来说

@GetMapping(path = "/a/{variableName:.+}")

确实工作，但只有当你也编码的“点”在你的请求url为“%2E”，然后它工作。但要求URL都是…虽然有效，但这不是“标准”编码。感觉像是一个bug:|

另一种类似于“后斜杠”的方法是移动带有点“inline”ex的变量:

@GetMapping(path = "/{variableName}/a")

现在所有的点都将被保留，不需要修改。

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;
    }
}

Spring 4的更新:从4.0.1开始，你可以使用PathMatchConfigurer(通过你的WebMvcConfigurer)。

@Configuration
protected static class AllResources extends WebMvcConfigurerAdapter {

    @Override
    public void configurePathMatch(PathMatchConfigurer matcher) {
        matcher.setUseRegisteredSuffixPatternMatch(true);
    }

}


@Configuration
public class WebConfig implements WebMvcConfigurer {

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

在xml中，它是(https://jira.spring.io/browse/SPR-10163):

<mvc:annotation-driven>
    [...]
    <mvc:path-matching registered-suffixes-only="true"/>
</mvc:annotation-driven>

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

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);
}

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").
