SpringBoot整合Pagehelper

1、导入依赖

		<dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper-spring-boot-starter</artifactId>
            <version>1.4.1</version>
        </dependency>
<!--        mysql8.0-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>

<!--        mybatis-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.3</version>
        </dependency>

2、编写yml文件

pagehelper:
  helper-dialect: mysql
  params: countSql
  reasonable: true
  support-methods-arguments: true

3、编写controller

@GetMapping("/types")
    public String types(@RequestParam(value = "pageNum",defaultValue = "1") Integer pageNum,
                        Model model){
		# 设置Pagehelper初始化 默认一页10条
        PageHelper.startPage(pageNum,10);
        # 查询所有对象
        List<Type> typelist = typeService.getAllType();
        # 将查询出来的对象放入pageinfo对象中封装保存
        PageInfo<Type> pageInfo = new PageInfo<>(typelist);
        # 将数据回显到网页上
        model.addAttribute(pageInfo);
        return "admin/types";
    }

4、前端代码

<tr>
                <th colspan="7">
                    <div class="ui inverted divided stackable grid">
                        <div class="two wide column" align="center">
                            <div class="item"><a th:href="@{/admin/types}">首页</a></div>
                        </div>
                        <div class="two wide column" align="center">
                            <div class="item"><a
                                    th:href="@{/admin/types(pageNum=${pageInfo.hasPreviousPage}?${pageInfo.prePage}:1)}">上一页</a>
                            </div>
                        </div>

                        <div class="eight wide m-text-thin column" align="center">
                            <p>第 <span th:text="${pageInfo.pageNum}"></span> 页，共 <span
                                    th:text="${pageInfo.pages}"></span> 页，有 <span
                                    th:text="${pageInfo.total}"></span> 个分类</p>
                        </div>

                        <div class="two wide column" align="center">
                            <div class="item"><a
                                    th:href="@{/admin/types(pageNum=${pageInfo.hasNextPage}?${pageInfo.nextPage}:${pageInfo.pages})}">下一页</a>
                            </div>
                        </div>
                        <div class="two wide column" align="center">
                            <div class="item"><a th:href="@{/admin/types(pageNum=${pageInfo.pages})}">尾页</a>
                            </div>
                        </div>
                    </div>
                </th>
            </tr>
