Spring Boot: avoiding PathVariable parameters getting truncated on dots

Using the @PathVariable on a Spring Boot controller, if a value contains a dot (‘.’) the value after the dot will be truncated. This happen since Spring MVC considers anything after the last dot as a file extension by default.

In order to avoid to getting truncated values it can be disabled this Spring MVC “feature” setting to false the useSuffixPatternMatch option through the PathMatchConfigurer:

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.PathMatchConfigurer;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

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

This configuration works for me with Spring Boot 1.2.2.
