How can i insert json into Postgres via java code?

Answer 1

Thank you :).This really helped me to resolve the issue.

String json = "{ \"name\": \"Book the First\", \"author\": { \"first_name\": \"Priya\", \"last_name\": \"White\" } }";
         PGobject jsonObject = new PGobject();
         jsonObject.setType("json");
         jsonObject.setValue(json);
         PreparedStatement stmt=c.prepareStatement("insert into books values(2,?)");
         stmt.setObject(1, jsonObject);

Answer 2

I have another one doubt.How to split JSON key value pair and insert into postgreSql table's column.

For example my JSON looks like { "Name":"xyz" "salary":10000 }

I want to insert into separate columns Name and salary in Postgres.
