如何将postgresql中的json列读取到java中？

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>版本号</version>
</dependency>

String sql = "SELECT json_column FROM table_name";
try (Connection connection = DriverManager.getConnection(url, username, password);
     Statement statement = connection.createStatement();
     ResultSet resultSet = statement.executeQuery(sql)) {
    while (resultSet.next()) {
        // 读取JSON列的值
        String jsonValue = resultSet.getString("json_column");
        // 在这里进行后续处理
    }
} catch (SQLException e) {
    e.printStackTrace();
}

ObjectMapper objectMapper = new ObjectMapper();
try {
    JsonNode jsonNode = objectMapper.readTree(jsonValue);
    // 在这里进行JSON数据的处理
} catch (JsonProcessingException e) {
    e.printStackTrace();
}
