@PathVariable和@RequestParam 异同

标签	说明	示范
@pathVariable("pageSize")	需要配合rest风格url使用，目的是接收rest Url中的参数	http://127.0.0.1:8082/hello/4
@RequestParam((value = "pageSize", required = false, defaultValue = "10"))	接收普通？后面携带的参数	http://127.0.0.1:8082/hello?pageSize=4

    @RequestMapping(value = "/hello/{pageSize}", method = RequestMethod.GET)
    public String say(@PathVariable("pageSize") String pageSize) {
        return pageSize;
    }

    @RequestMapping(value = "/hello", method = RequestMethod.GET)
    public String say2(@RequestParam(value = "pageSize", required = false, defaultValue = "10") String pageSize) {
        return pageSize;
    }
