Mybatisplus分页插件的使用

一、加依赖:

1   <dependency>
2             <groupId>com.baomidou</groupId>
3             <artifactId>mybatis-plus</artifactId>
4             <version>${mybatis-plus.version}</version>
5   </dependency>

二、加配置:

1  <plugins>
2         <!-- 分页查询插件 -->
3         <plugin interceptor="com.baomidou.mybatisplus.plugins.PaginationInterceptor">
4             <property name="dialectType" value="mysql" />
5         </plugin>
6  </plugins>

 三、controller使用:

1     @PostMapping("orderlist.api")
2     @ApiOperation(value = "分页查询", produces = MediaType.APPLICATION_JSON_VALUE)
3     public Object memberOrderlist(@RequestBody DriverDto dto, HttpServletRequest request, HttpServletResponse response) {
4       Page<BizOrderlist> page = new Page<BizOrderlist>(dto.getPage() == null ? 1 : dto.getPage() , dto.getPageSize() == null ? 15 : dto.getPageSize()); //初始化分页条数,如果传入的值为空在默认第一页,15条。
5       Parameter orderparameter = new Parameter(getService(), "getOrderlist").setParam(page,params); //在servie中获取list,传递分页Page和查询参数
6       Page<BizOrderlist>  orderList = (Page<BizOrderlist>) provider.execute(orderparameter).getResult();    

四、service中使用:

1  public Page<BizOrderlist> getOrderlist(Page<BizOrderlist> page,Map<String, Object> params) {
2         
3         List<BizOrderlist> orderlist = (List<BizOrderlist>) ((OrderListMapper) mapper).getOrderList(page,param1,params2,params3);
4         page = page.setRecords(orderlist);  //查出的list调用setRecords
5         return page;

五、Mapper:

1   public interface OrderListMapper extends BaseMapper<BizOrderlist> {
2 
3     List<BizOrderlist> getOrderList(Pagination  page,@Param("param1") Double param1...........);
