Question

与标题一样，您是否知道有可能在@PathVariable下的春季为所有@RequestMapping设置全局正则表达式？例如：

@RequestMapping(value = "/view/{id:[a-z]{5}|[1-9]{7}}", method = RequestMethod.GET)
    @PreAuthorize("hasRole('XXXX')")
    public String viewId(@PathVariable String id, Model model) {
        ...
    }

我不想将regexp本地设置为{id:[a-z]{5}|[1-9]{7}}，但我想在可能的地方设置它。另外我有配置，我不想改变：

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = {"com.xxxx.yyy.zzz.controller.formatters"})
public class MediaPortalWebConfig extends WebMvcConfigurationSupport {
@Override
    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping requestMappingHandlerMapping = super.requestMappingHandlerMapping();
        requestMappingHandlerMapping.setUseSuffixPatternMatch(false);
        return requestMappingHandlerMapping;
    }
}

所以我知道setUseSuffixPatternMatch(false);的意思是什么，这必须保持弹簧配置。

您可以编写自定义路径匹配器，例如CustomRegexPathMatcher通过扩展默认AntPathMatcher并覆盖其doMatch方法，以便在对网址执行匹配时考虑您的正则表达式

比你想要的更像

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = {"com.xxxx.yyy.zzz.controller.formatters"})
public class MediaPortalWebConfig extends WebMvcConfigurationSupport {
@Override
    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping requestMappingHandlerMapping = super.requestMappingHandlerMapping();
        requestMappingHandlerMapping.setUseSuffixPatternMatch(false);
        requestMappingHandlerMapping.setPathMatcher(new CustomRegexPathMatcher());
        return requestMappingHandlerMapping;
    }
}

是否有可能在springMVC @PathVariable上设置全局正则表达式模式？
