You have to use @PathVariablein order to do this. Example:
你必须使用@PathVariable才能做到这一点。例子：
Jsp:
jsp：
<a href="<c:url value="/test/${object.argument}" />" >hello</a>
Controller:
控制器：
@RequestMapping(value = "/test/{argument}", method = RequestMethod.GET)
public String Controller(@PathVariable("argument") String argument) {
...
}

I have resolved the answer by creating a link:
我已经通过创建链接解决了答案：
<a href=".../test?argName=arg1" >hello</a>
Controller:
控制器：
@RequestMapping(value = "/test", method = RequestMethod.GET, params = {"argName"})
public String Controller(@RequestParam(value="argName", required = true, defaultValue = null) String argName) {
...
//Now do exciting things with variable argName
}
