我可以在SpringMVC的RequestMapping中为路径变量设置默认值吗？

Question

是否有可能在SpringMVC中为@PathVariable设置默认值？

 @RequestMapping(value = {"/core/organization/{pageNumber}", "/core/organization"} , method = RequestMethod.GET)
    public String list(@PathVariable Integer pageNumber, ModelMap modelMap) {

在这种情况下.如果我访问没有pageNumber的页面,我想将默认值设置为1.

那可能吗？

Answer 1

无法设置默认值，但您可以创建两种方法：

@RequestMapping(value = {"/core/organization/{pageNumber}", "/core/organization"} , method = RequestMethod.GET)
    public String list(@PathVariable Integer pageNumber, ModelMap modelMap){
...
}


@RequestMapping(value = {"/core/organization/", "/core/organization"} , method = RequestMethod.GET)
    public String list(@PathVariable Integer pageNumber, ModelMap modelMap){
Integer pageNumber=defaultvalue;
...
}
