我想创建一个对象并将其保存到数据库
Log l = new Log();
l.setTimestamp("creation_date", Util.getCurrentTimestamp());
l.setString("app_name", "name");
l.setString("log_type", "type");
l.setLong("user_id", 9l);
l.setLong("module_element_id", 9);
l.set("info", JsonHelper.toJsonString("{}"));
l.save();
我尝试过多次尝试,但总是得到这个错误:
ERROR: column "info" is of type jsonb but expression is of type character varying
如何插入jsonb?
编辑(DDL):
- 表:public.log
- DROP TABLE public.log;
CREATE TABLE public.log
(
id bigint NOT NULL DEFAULT nextval('log_id_seq'::regclass),
creation_date timestamp without time zone,
app_name text,
log_type text,
user_id bigint,
module_element_type bigint,
info jsonb,
CONSTRAINT log_pkey PRIMARY KEY (id)
)
WITH (
OIDS=FALSE
);
ALTER TABLE public.log
OWNER TO postgres;

目前框架中缺少此实现。它已在https://github.com/javalite/activejdbc/issues/640中报告过。如果您可以帮助跟踪Postgres文档中所有与PreparedStatement一起使用此语法的Postgres数据类型:
UPDATE my_table SET status = ?::status_type WHERE id = ?
然后,我将能够快速为PostgreSQL方言实现它:https://github.com/javalite/activejdbc/blob/master/activejdbc/src/main/java/org/javalite/activejdbc/dialects/PostgreSQLDialect.java
