准备，下载eighth.zip并导入到eclipse，下载地址http://pan.baidu.com/s/1c2GaAFA。
同时，请导入Limy插件，Limy(eclipse_plugin).zip。下载完成后解压到eclipse的dropins目录下即可以使用。下载地址http://pan.baidu.com/s/1o6spOJS。(eclipse_plugins\Limy(eclipse_plugin).zip)
1,新规messages.properties(请使用Limy编辑)
I0000001=没有检索到结果。2，修改users.html
Users
Users
3,修改UsersController.java
package org.com.sample.controller;
import java.util.HashMap;
import java.util.Locale;
import java.util.Map;
import org.com.common.paging.PagenationHelper;
import org.com.sample.dataset.Users;
import org.com.sample.facade.UsersFacade;

@Controller
@RequestMapping("/sample/users")
public class UsersController {
private static final Logger logger = LoggerFactory.getLogger(UsersController.class);
private static final int DEFAULT_PAGEABLE_SIZE = 10;
@Autowired

@Autowired

@RequestMapping(value = "/show", method = { RequestMethod.GET, RequestMethod.POST })
public String selectAllUser(@PageableDefault(page = 0, size = DEFAULT_PAGEABLE_SIZE) Pageable pageable,
Model model) {
// List userList = usersFacade.selectByExample(new

Map map = new HashMap();
map.put("start_line", pageable.getOffset() + 1);
map.put("end_line", (pageable.getPageNumber() + 1) * pageable.getPageSize());
map.put("orderByClause", "username asc");
map.put("form", new UsersInputForm());
Page page = usersFacade.selectUserListForPaging(map, pageable);
PagenationHelper ph = null;
if (page != null) {
ph = new PagenationHelper(page.getNumber(), page.getSize(), page.getTotalPages());
} else {
model.addAttribute("sysMsg", messageSource.getMessage("I0000001", null, Locale.getDefault()));
}
model.addAttribute("page", page);
model.addAttribute("ph", ph);
return "sample/users/users";
}
@RequestMapping(value = "/doSearch", method = { RequestMethod.GET, RequestMethod.POST })
public String doSearch(UsersInputForm form, BindingResult result,
@PageableDefault(page = 0, size = DEFAULT_PAGEABLE_SIZE) Pageable pageable, Model model) {
Map map = new HashMap();
map.put("start_line", pageable.getOffset() + 1);
map.put("end_line", (pageable.getPageNumber() + 1) * pageable.getPageSize());

PagenationHelper ph = null;
if (page != null) {
ph = new PagenationHelper(page.getNumber(), page.getSize(), page.getTotalPages());
} else {
model.addAttribute("sysMsg", messageSource.getMessage("I0000001", null, Locale.getDefault()));
}
model.addAttribute("page", page);
model.addAttribute("ph", ph);
return "sample/users/users";
}
@ModelAttribute
public UsersInputForm getUsersInputForm() {
return new UsersInputForm();
}
}
4, 启动项目，输入URL，http://localhost:8888/sample/users/show
输入检索条件进行检索。
