Spring REST @RequestMapping extract incorrectly if value contains ‘.’
Problem
See following Spring REST example, if a request such as “http://localhost:8080/site/google.com
” is submitted, Spring returns “google“. Look like Spring treats “.” as file extension, and extract half of the parameter value.
SiteController.java
package com.mkyong.web.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/site")
public class SiteController {
@RequestMapping(value = "/{domain}", method = RequestMethod.GET)
public String printWelcome(@PathVariable("domain") String domain,
ModelMap model) {
model.addAttribute("domain", domain);
return "domain";
}
}
Solution
To fix it, make @RequestMapping
supports regular expression, add “.+
“, it means match anything. Now, Spring will return “google.com“.
SiteController.java
package com.mkyong.web.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/site")
public class SiteController {
@RequestMapping(value = "/{domain:.+}", method = RequestMethod.GET)
public String printWelcome(@PathVariable("domain") String domain,
ModelMap model) {
model.addAttribute("domain", domain);
return "domain";
}
}
what about the # ?
