如何在Spring Data JPA中使用Example返回包含特定字符串的记录

Question

我正在尝试使用JpaRepository返回名称字段中包含特定字符串的任何记录。 我用http://localhost:8080/teacher?name=Poppy

给控制器打电话

这是我的程序：

if 'PixelData' in dataset:
      rows = int(dataset.Rows)
      cols = int(dataset.Columns)
  y=rows
  x=cols
  p=np.array(data)
  fig = Figure(figsize=(6,6))
  a = fig.add_subplot(111)
  a.plot(p, range(2+y))

教师实体：

Sub fillLeads()
'
' fillLeads Macro
    Last = Cells(Rows.Count, "B").End(xlUp).Row
    cellValue = Range("B2").Value
    openingParen = InStr(cellValue, "(")
    closingParen = InStr(cellValue, ")")
    enclosedValue = Mid(cellValue, openingParen + 1, closingParen - openingParen - 1)
    For i = Last To 2 Step -1
        Cells(i, "C").Value = enclosedValue
    Next i
End Sub

教师资料库：

@RestController
@RequestMapping("/teacher")
public class TeacherController {

    @Autowired
    private TeacherRepository teacherRepository;

    @GetMapping
    public List<Teacher> findAll(@RequestParam(name = "name") String strName) {

        Teacher teacherExample = new Teacher();
        teacherExample.setName(strName); //strName = "Poppy"

        Example<Teacher> example = Example.of(teacherExample);

        List<Teacher> teachers = teacherRepository.findAll(example);
        return teachers;  //the result are : [], I expected Ms. Poppy

    }
}

Data.Sql

@Entity
public class Teacher {
    @Id
    private String id;

    private String name;
    Getter & Setter here..
}

我的其他控制器给我正确的结果。

@Repository
interface TeacherRepository extends JpaRepository<Teacher, String> {

}

谢谢
