java - com.fasterxml.jackson.databind.exc.MismatchedInputException : Can not deserialize instance of object out of START_ARRAY token

获取MismatchedInputException。在这里搜索了很多问题,但发现JSONMappingException居多。我不明白它们是相同还是不同。实体如下:@Entity@Table@NamedQueries({@NamedQuery(name="User.findAll",query="SELECTuFROMUseru"),@NamedQuery(name="User.findByEmail",query="SELECTuFROMUseruWHEREu.email=:pEmail")})publicclassUser{@Id@GenericGenerator(name="i

nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException:【问题解决】
