Spring MVC @PathVariable with dot (.) is getting t

Question

This is continuation of question Spring MVC @PathVariable getting truncated

Spring forum states that it has fixed(3.2 version) as part of ContentNegotiationManager. see the below link.
https://jira.springsource.org/browse/SPR-6164
https://jira.springsource.org/browse/SPR-7632

In my application requestParameter with .com is truncated.

Could anyone explain me how to use this new feature? how is it configurable at xml?

Note: spring forum- #1 Spring MVC @PathVariable with dot (.) is getting truncated

Answer 1

If you are using Spring 3.2.x and <mvc:annotation-driven />, create this little 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;
    }
}

Then put this in your MVC config xml:

<bean class="spring.DoNotTruncateMyUrls" />

Answer 2

Finally I found solution in Spring Docs:

To completely disable the use of file extensions, you must set both of the following:

 useSuffixPatternMatching(false), see PathMatchConfigurer

 favorPathExtension(false), see ContentNegotiationConfigurer

Adding this to my WebMvcConfigurerAdapter implementation solved the problem:

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

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

Answer 3

/somepath/{variable:.+} works in Java requestMapping tag.

Answer 4

Here's an approach that relies purely on java configuration:

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;
    }
}

Answer 5

In Spring Boot, The Regular expression solve the problem like

@GetMapping("/path/{param1:.+}")

Answer 6

adding the ":.+" worked for me, but not until I removed outer curly brackets.

value = {"/username/{id:.+}"} didn't work

value = "/username/{id:.+}" works

Hope I helped someone :)
