SSM框架实现分页插件(利用分页插件实现的)

第一步:引入分页插件

<dependency>
   <groupId>com.github.pagehelper</groupId>
   <artifactId>pagehelper</artifactId>
   <version>4.1.5</version>
  </dependency>

第二步:在src/main/resourse下面新建一个sqlConfig.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>


<plugins>
<plugin interceptor="com.github.pagehelper.PageHelper"></plugin>
</plugins>
</configuration>

第三步:controller类

/**
     * 分页查询用户信息
     * @param pn 默认从第一页开始请求参数
     * @param model
     * @return
     */
    @RequestMapping("/showUser.do")
    public String getUsers(@RequestParam(value="pn",defaultValue="1")Integer pn,Model model){
        //从第一条开始每页查询五条数据
    PageHelper.startPage(pn, 5);
        List<User> users = userService.selectUser();
        System.out.println(users.size());
        //将用户信息放入PageInfo对象里
        PageInfo page = new PageInfo(users,5);
        model.addAttribute("pageInfo", page);
        model.addAttribute("userList",users);
        return "index";
    }

第四步:jsp页面

<div class="row">
            
            <div class="col-md-6">
                当前第：${pageInfo.pageNum}页，总共：${pageInfo.pages}页，总共：${pageInfo.total}条记录
            </div>

<div class="col-md-6">
                <nav aria-label="Page navigation">
                  <ul class="pagination">
                    <li><a href="${pageContext.request.contextPath}/showUser.do?pn=1">首页</a></li>
                    <c:if test="${pageInfo.hasPreviousPage }">
                         <li>
                          <a href="${path}/showUser.do?pn=${pageInfo.pageNum-1}" aria-label="Previous">
                            <span aria-hidden="true">«</span>
                          </a>
                        </li>
                    </c:if>

                    <c:forEach items="${pageInfo.navigatepageNums }" var="page_Num">
                        <c:if test="${page_Num == pageInfo.pageNum }">
                            <li class="active"><a href="#">${ page_Num}</a></li>
                        </c:if>
                        <c:if test="${page_Num != pageInfo.pageNum }">
                            <li><a href="${pageContext.request.contextPath}/showUser.do?pn=${ page_Num}">${ page_Num}</a></li>
                        </c:if>
                    </c:forEach>
                    <c:if test="${pageInfo.hasNextPage }">
                        <li>
                          <a href="${pageContext.request.contextPath}/showUser.do?pn=${pageInfo.pageNum+1}" aria-label="Next">
                            <span aria-hidden="true">»</span>
                          </a>
                        </li>
                    </c:if>
                    <li><a href="${pageContext.request.contextPath}/showUser.do?pn=${pageInfo.pages}">末页</a></li>
                  </ul>
                </nav>
            </div>
        </div>

  </div>
</div>

这就完成了利用分页插件实现分页功能.
