我们首先来看具体的报错：

翻译成大白话就是：org.springframework.data.domain.PageRequest，他初始化失败。那么问题就是org.springframework.data.domain.PageRequest是什么，在哪里？

我截取的是easycode插件自动生成的controller层代码

>     /**
>      * 分页查询
>      *
>      * @param tbAction 筛选条件
>      * @param pageRequest      分页对象
>      * @return 查询结果
>      */
>     @GetMapping
>     public ResponseEntity<Page<TbAction>> queryByPage(TbAction tbAction, PageRequest pageRequest) {
>         return ResponseEntity.ok(this.tbActionService.queryByPage(tbAction, pageRequest));
>     }

可以看到在queryByPage方法中要求我们传入两个参数 ，一个是实体类，一个就是PageRequest。

由于我们没有进行PageRequest相关的配置，自然就会报错。

鉴于easycode的分页查询有点复杂，我的业务中目前不需要这个，后面需要了再来弄，如果你的业务需要，请移步其他博主。

如果只是想测试数据库连接，我们可以用其他方法，不用这个分页查询

> [http://localhost:8080/helpwork/tbAction][http_localhost_8080_helpwork_tbAction]/1

比如上面的就是根据id查数据，并非分页查询

自然是能够查询成功的
