Spring-GET URL中的斜线字符 [英] Spring - slash character in GET URL

问题描述

我有一个GET方法

@RequestMapping(
        value = "/path/{field}",
        method = RequestMethod.GET
)
public void get(@PathVariable String field) {
}

字段可以包含斜杠，例如"some/thing/else"，这将导致找不到路径.甚至可能是"//////////////"之类的东西.一些例子:

Field can contain slashes, like "some/thing/else" which results in the path not being found. It could even be something like "//////////////". Some examples:

www.something.com/path/field //works
www.something.com/path/some/thing
www.something.com/path///////////

我已经尝试过使用{field:.*}并使用％2F转义斜线，但是仍然无法达到该方法.有帮助吗?

I've tried with {field:.*} and escaping the slash with %2F but it still won't reach the method. Some help?

推荐答案

对于Spring Boot，我已经解决了这个问题.首先，您必须将Spring配置为允许编码的斜杠.

I've solved the problem, for Spring Boot. First you have to configure Spring to allow encoded slashes.

@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Bean
    public HttpFirewall allowUrlEncodedSlashHttpFirewall() {
        DefaultHttpFirewall firewall = new DefaultHttpFirewall();
        firewall.setAllowUrlEncodedSlash(true);
        return firewall;
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.httpFirewall(allowUrlEncodedSlashHttpFirewall());
    }
}

然后您需要从嵌入式tomcat中允许它:

Then you need to allow it from the embedded tomcat:

public class Application extends WebMvcConfigurerAdapter {

    public static void main(String[] args) {
        System.setProperty("org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH", "true");
        SpringApplication.run(Application.class, args);
    }

    @Override
    public void configurePathMatch(PathMatchConfigurer configurer) {
        UrlPathHelper urlPathHelper = new UrlPathHelper();
        urlPathHelper.setUrlDecode(false);
        configurer.setUrlPathHelper(urlPathHelper);
    }
}

尽管这可行，但最好的方法是只使用查询参数.

Although this works, the best way to do it is to just use query parameters instead.
