Question

将字符串反序列化为对象时遇到错误。

org.opentest4j.MultipleFailuresError：多次失败（2次失败） com.fasterxml.jackson.databind.exc.InvalidDefinitionException：无法 构造java.time.LocalDate的实例（没有创建者，如默认 构造，存在）：无字符串参数构造函数/工厂方法 从[来源：(字符串）

的字符串值（'2020-05-20'）反序列化

JSON

 {
       "studentId":57,
       "JoinedDate":"31-12-2019",
       "DOB":"08-06-1998"  

    }
型号

public class Student{

    private long studentId ;

    private LocalDate JoinedDate;

    private LocalDate DOB ;

    public long getStudentId() {
        return studentId;
    }

    public void setStudentId(long studentId) {
        this.studentId = studentId;
    }

    public LocalDate getJoinedDate() {
        return JoinedDate;
    }

    public void setJoinedDate(LocalDate joinedDate) {
        JoinedDate = joinedDate;
    }

    public LocalDate getDOB() {
        return DOB;
    }

    public void setDOB(LocalDate dOB) {
        DOB = dOB;
    }
单元测试类

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Main.class)
@WebAppConfiguration
public class StudentTest{


private Student student;
private ObjectMapper jsonObjectMapper;
@Before
public void setUp() throws IOException {

    jsonObjectMapper = new ObjectMapper();
    jsonObjectMapper.setDateFormat(new SimpleDateFormat("dd-MM-yyyy"));
    studentJson = IOUtils.toString(getClass().getResourceAsStream(CommonTestConstants.StudentPath+ "/Student.json"));


student = jsonObjectMapper.readValue(studentJson , Student.class);
}
任何人请指教
