@PathVariable will cut off the last point [SPR-14678]

mashuai opened SPR-14678 and commented

When use @PathVariable like

@RequestMapping(value = "/test/{test}", method = RequestMethod.GET)
   @ResponseBody
   public String test(@PathVariable("test") String test, HttpServletResponse response) throws IOException {
       System.out.println(test);
       return test;
   }

if let the test like 1.0.0.0.1 the test wil be 1.0.0.0 not expect

This is expected behavior, and there are several ways to get around that.
You can read up about that in #12288.

You could add a regexp in your mapping pattern:

@RequestMapping(value = "/test/{test:.+}", method = RequestMethod.GET)

Or you can configure the file extensions that should be considered for content negotiation and turn the suffix pattern matching off for your whole application:

@Configuration
public class MyMvcConfiguration extends WebMvcConfigurerAdapter {
  @Override
  public void configurePathMatch(PathMatchConfigurer configurer) {
    configurer. setUseRegisteredSuffixPatternMatch(false);
  }

  @Override
  public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
    // register here the extension/mediaType with configurer.mediaType(...)
  }
}
