在Controller的一个方法中添加 int a = 10/0; 使调用方法时产生异常。

    | @GetMapping(value = “/pageTeacher/{current}/{limit}”)
    public R pageListTeacher(@ApiParam(name = “current”, value = “当前页码”, required = true)
    @PathVariable Long current,
    @ApiParam(name = “limit”, value = “每页记录数”, required = true)
    @PathVariable Long limit){
    int a = 10/0;
    Page pageTeacher = new Page<>(current,limit);
    //调用 page() 方法时候，底层封装，把分页所有数据封装到 pageTeacher
    eduTeacherService.page(pageTeacher, null);

    1. **long **total = pageTeacher.getTotal();//总记录数<br />    List<EduTeacher> records = pageTeacher.getRecords();//数据的list集合<br />    **return **R.ok().data(**"total"**,total).data(**"rows"**,records);<br />} |

    在Swagger 中测试上述方法：
    得到结果
