CLOB财产我有实体进口同类Maven的依赖,看起来像这样(简体)创建从JSON
@Entity
public class Person extends Base {
private String name;
private Clob biography;
//Getters and setters
我收到此JSON与POST方法
{"name":"John Doe",
"biography":"dragonborn"}
而且我得到了这个错误
"status": 400,
"error": "Bad Request",
"exception": "org.springframework.http.converter.HttpMessageNotReadableException",
"message": "Could not read document: Can not construct instance of java.sql.Clob,
problem: abstract types either need to be mapped to concrete types, have custom deserializer, or be instantiated with additional type information\n at
[Source: [email protected]; line: 2, column: 13] (through reference chain: com.example.Person[\"biography\"]);
nested exception is com.fasterxml.jackson.databind.JsonMappingException:
Can not construct instance of java.sql.Clob,

"path": "/persons"
如果“biography”是String,Person是cre ated。 如何将JSON属性转换为java.sql.Clob属性? 最好的解决方案将调整ObjectMapper,但我很乐意听到任何建议。谢谢!
