springboot整合Pagehelper分页插件-CFANZ编程社区

2.在pom文件中引入Pagehelper分页插件

<!-- 分页插件 -->
<dependency>
    <groupId>com.github.pagehelper</groupId>
    <artifactId>pagehelper-spring-boot-starter</artifactId>
    <version>1.2.5</version>
</dependency>

3.配置分页插件，打开application.properties，添加如下几行配置信息

#分页插件
pagehelper.helper-dialect=mysql
pagehelper.params=count=countSql
pagehelper.reasonable=true
pagehelper.support-methods-arguments=true

在contoller中使用分页功能

@Controller
public class PersonController {
    @Autowired
    private PersonService personService;
 
    @GetMapping("/getAllPerson")
    public String getAllPerson(Model model,@RequestParam(defaultValue = "1",value = "pageNum") Integer pageNum){
        PageHelper.startPage(pageNum,5);
        List<Person> list = personService.getAllPerson();
        PageInfo<Person> pageInfo = new PageInfo<Person>(list);
        model.addAttribute("pageInfo",pageInfo);
        return "list";
    }
}

前端代码

    <meta charset="UTF-8">
    <title>Title</title>

            <th>age</th>
        </tr>
        <tr th:each="person:${pageInfo.list}">
            <td th:text="${person.id}"></td>
            <td th:text="${person.name}"></td>
            <td th:text="${person.sex}"></td>
            <td th:text="${person.age}"></td>
        </tr>
    </table>
    <p>当前 <span th:text="${pageInfo.pageNum}"></span> 页,总 <span th:text="${pageInfo.pages}"></span> 页,共 <span th:text="${pageInfo.total}"></span> 条记录</p>
    <a th:href="@{/getAllPerson}">首页</a>
    <a th:href="@{/getAllPerson(pageNum=${pageInfo.hasPreviousPage}?${pageInfo.prePage}:1)}">上一页</a>
    <a th:href="@{/getAllPerson(pageNum=${pageInfo.hasNextPage}?${pageInfo.nextPage}:${pageInfo.pages})}">下一页</a>
