springboot整合mybatis分页插件

1.springboot版本为2.0.1，数据库为mysql，引入pagehelper的pom依赖

<!--mybatis分页插件--> 
         <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper-spring-boot-starter</artifactId>
            <version>1.2.3</version>
        </dependency>

如果引入不兼容版本，启动报错

2.不要另外配置，使用默认配置即可。

@RequestMapping("/list")
    public PageInfo<BaseRole> pageByExample(BaseRole record,int page,int limit){
        PageHelper.startPage(page, limit);
        List<BaseRole> list = service.selectAll(record);
        PageInfo<BaseRole> pageInfo = new PageInfo<BaseRole>(list);
        return pageInfo;
        
    }

3.请求如下

http://localhost:8080/list?page=1&limit=2

结果如下

    "pageNum": 1,
    "pageSize": 2,
    "size": 2,
    "startRow": 1,
    "endRow": 2,
