mybatisplus分页插件

1.在配置类中添加分页插件

@Configuration
@EnableTransactionManagement
@MapperScan("xxx.xxx.xxx.xxx")
public class MybatisPlusConfig {
    /**
     * 分页插件
     */
    @Bean
    public PaginationInterceptor getPaginationInterceptor(){
        return new PaginationInterceptor();
    }
 
}

2.创建测试类进行方法的调用

@SpringBootTest
public class MybatisPlusTest {
 
    @Autowired
    private UserMapper userMapper;
 
    @Test
    public void selectByPage(){
        Page userPage = new Page<>(2,3);
        userMapper.selectPage(userPage,null);
        List records = userPage.getRecords();
        records.forEach(System.out::println);
        System.out.println(userPage.getCurrent());
        System.out.println(userPage.getPages());
        System.out.println(userPage.getSize());
        System.out.println(userPage.getTotal());
        System.out.println(userPage.hasNext());
        System.out.println(userPage.hasPrevious());
    }
}
