尽管对于答案(对于插入部分)而言为时已晚,但我希望对其他人可能有用:
在HashMap中获取键/值对:
Map<String, String> hstoreMap = new HashMap<>();hstoreMap.put("key1", "value1");hstoreMap.put("key2", "value2");PGobject jsonbObj = new PGobject();jsonbObj.setType("json");jsonbObj.setValue("{"key" : "value"}");使用以下方式之一将它们插入PostgreSQL:
1)
jdbcTemplate.update(conn -> { PreparedStatement ps = conn.prepareStatement( "INSERT INTO table (hstore_col, jsonb_col) VALUES (?, ?)" ); ps.setObject( 1, hstoreMap ); ps.setObject( 2, jsonbObj );});2)
jdbcTemplate.update("INSERT INTO table (hstore_col, jsonb_col) VALUES(?,?)", new Object[]{ hstoreMap, jsonbObj }, new int[]{Types.OTHER, Types.OTHER});3)在POJO中设置hstoreMap / jsonbObj(Map类型的hstoreCol和jsonbObjCol类型为PGObject)
BeanPropertySqlParameterSource sqlParameterSource = new BeanPropertySqlParameterSource( POJO );sqlParameterSource.registerSqlType( "hstore_col", Types.OTHER );sqlParameterSource.registerSqlType( "jsonb_col", Types.OTHER );namedJdbcTemplate.update( "INSERT INTO table (hstore_col, jsonb_col) VALUES (:hstoreCol, :jsonbObjCol)", sqlParameterSource );
并获得价值:
(Map<String, String>) rs.getObject( "hstore_col" ));((PGobject) rs.getObject("jsonb_col")).getValue();
