[Failed to convert property value of type 'java.lang.String' to required type 'java.util.Date' for property 'beginTime';

依照https://stackoverflow.com/questions/23702041/failed-to-convert-property-value-of-type-java-lang-string-to-required-type-java文章所说：

加上如下注解：

@DateTimeFormat(pattern = "dd/MM/yyyy")
@Temporal(TemporalType.DATE)

具体代码如下

@Data
public class WrongAnswerRecordParam extends BasicParam{
    private Byte source;

    @NotNull(message="用户ID不能为空")
    private Long userId;
    private Long wrongAnswerId;
    private Long wrongAnswerTagId;
    private Long questionId;
    private Byte taskId;
    private Long groupId;
    private Integer subjectId;
    private String comment;
    private Long tagId;
    private Byte type;
    private Date updateTime;
    private Date createTime;

    @DateTimeFormat(pattern = "yyyy-MM-dd")
    private Date beginTime;

    @DateTimeFormat(pattern = "yyyy-MM-dd")
    private Date endTime;
}

解决
