零) 代码

import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping(value = "/c")
public class TestController {

	@ResponseBody
	@RequestMapping(value = "/t1", method = RequestMethod.GET)
	// http://localhost:8080/c/t1?page.page=2&page.size=50&page.sort=email&page.sort.dir=desc
	public Object test1(Pageable pageable) {
		PageRequest p = (PageRequest) pageable;
		System.out.println(p.getPageNumber() + " " + p.getPageSize() + " " + p.getSort());
		return "OK";
	}
	
	@ResponseBody
	@RequestMapping(value = "/t2/{id}", method = RequestMethod.GET)
	// http://localhost:8080/c/t2/1
	public Object test2(@PathVariable("id") User user) {
		return user;
	}

}

一) Web Pagination
代码参考上面的 test1()
这需要一个WebArgumentResolver实现，这个接口我还第一次注意，MethodArgumentResolver用过，两者用法大同小异。

二) Domain class web binding for Spring MVC
代码参考上面 test2()
与Web Pagination 不同，这里不是使用的WebArgumentResolver或MethodArgumentResolver,而是注册PropertyEditor，
注册时这两个bean放在root上下文之中
