JDBC写入postgresql json格式出现以下错误:
Caused by: org.postgresql.util.PSQLException: ERROR: column "stu_json" is of type json but expression is of type character varying
建议:You will need to rewrite or cast the expression.
解决方案:
在连接参数中加入:&stringtype=unspecified
用于把JSON类型当STRING类型存储
或者使用PGobject对象来传输
PGobject pgobject = new PGobject();
pgobject.setType("json");
pgobject.setValue(jsonString);
