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
<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"xmlns:th="http://www.thymeleaf.org"><head><meta charset="UTF-8" /><title>Users</title><metacontent='width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no'name='viewport' /><meta th:replace="head-cssjs" /></head><body class="skin-blue"><div class="wrapper"><!-- Content Wrapper.

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;import org.com.sample.form.UsersInputForm;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.MessageSource;import org.springframework.data.domain.Page;import org.springframework.data.domain.Pageable;import org.springframework.data.web.PageableDefault;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.validation.BindingResult;import org.springframework.web.bind.annotation.ModelAttribute;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;@Controller@RequestMapping("/sample/users")public class UsersController {private static final Logger logger = LoggerFactory.getLogger(UsersController.class);private static final int DEFAULT_PAGEABLE_SIZE = 10;@AutowiredUsersFacade usersFacade;@AutowiredMessageSource messageSource;@RequestMapping(value = "/show", method = { RequestMethod.GET, RequestMethod.POST })public String selectAllUser(@PageableDefault(page = 0, size = DEFAULT_PAGEABLE_SIZE) Pageable pageable,Model model) {// List<Users> userList = usersFacade.selectByExample(new// UsersExample());Map<String, Object> map = new HashMap<String, Object>();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<Users> 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<String, Object> map = new HashMap<String, Object>();map.put("start_line", pageable.getOffset() + 1);map.put("end_line", (pageable.getPageNumber() + 1) * pageable.getPageSize());map.put("orderByClause", "username asc");map.put("form", form);Page<Users> 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";}@ModelAttributepublic 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。
