後臺通過mybatis外掛pageHelper實現分頁查詢

先上效果圖

maven地址

                <dependency>
			<groupId>com.github.pagehelper</groupId>
			<artifactId>pagehelper-spring-boot-starter</artifactId>
			<version>1.2.3</version>
		</dependency>

controller

@RequestMapping("/index")
    public String index(Model model,Integer pageNumber){
        if (pageNumber == null){
            pageNumber = 1;
        }
        PageHelper.startPage(pageNumber,3);
        List<ScoreReport> list = this.scoreReportService.getPageList();
        PageInfo<ScoreReport> pageInfo = new PageInfo<>(list);
        model.addAttribute("pageInfo",pageInfo);
        return "score";
    }
 

 PageHelper.startPage()方法下需要就應該是查詢語句

大概意思就是我要開始查詢了，準備分頁吧

前臺頁面網上參考地址找不到了

上js程式碼

<div style="float: right;">
    <div style="float: right;">
        當前${pageInfo.pageNum}頁,共${pageInfo.pages }頁,總${pageInfo.total }條記錄
    </div>
    <div>
        <ul class="pagination">
            <!--
                1.pageContext.request.contextPath表示當前專案路徑，採用的是絕對路徑表達方式。一般為http:localhost:8080/專案名 。
                2.首頁，末頁的邏輯：pn=1訪問第一次，pn=${pageInfo.pages}訪問最後一頁
              -->
            <li>
                <a href="${pageContext.request.contextPath}/index?pageNumber=1">首頁</a>
            </li>
            <!-- 如果還有前頁就訪問當前頁碼-1的頁面， -->
            <c:if test="${pageInfo.hasPreviousPage}">
                <li>
                    <a href="${pageContext.request.contextPath}/index?pageNumber=${pageInfo.pageNum-1}" aria-label="Previous">
                        <span aria-hidden="true">&laquo;</span>
                    </a>
                </li>
            </c:if>
            <li>
                <!--遍歷所有導航頁碼，如果遍歷的頁碼頁當前頁碼相等就高亮顯示，如果相等就普通顯示  -->
                <c:forEach items="${pageInfo.navigatepageNums }" var="page_Nums">
                <c:if test="${page_Nums==pageInfo.pageNum }">
            <li class="active"><a href="#">${page_Nums}</a></li>
            </c:if>
            <c:if test="${page_Nums!=pageInfo.pageNum }">
                <li ><a href="${pageContext.request.contextPath}/index?pageNumber=${page_Nums}">${page_Nums}</a></li>
            </c:if>
            </c:forEach>
            </li>
            <!-- 如果還有後頁就訪問當前頁碼+1的頁面， -->
            <c:if test="${pageInfo.hasNextPage}">
                <li>
                    <a href="${pageContext.request.contextPath}/index?pageNumber=${pageInfo.pageNum+1}" aria-label="Next">
                        <span aria-hidden="true">&raquo;</span>
                    </a>
                </li>
            </c:if>
            <li><a href="${pageContext.request.contextPath}/index?pageNumber=${pageInfo.pages}">末頁</a></li>
        </ul>
    </div>
</div>
