我正在尝试在 jdbc 中测试 SCRAM-SHA-256。
public static void main(String[] args) throws SQLException {
String url = "jdbc:postgresql://192.168.56.101:1521/gisdb";
Properties props = new Properties();
props.setProperty("user", "pguser");
String scram = "SCRAM-SHA-256$4096:QNTBYMpbvZjbOx5RLM7rvA==$tuBD7Ek7niK8jyiuwjCGLH2EurqMNoIaclZhOXohyik=:2b0Ow951/1OPKsqzaGLWPyT+wVIXOs9dvY8TF2eTCVM=";
props.setProperty("password", scram);
// props.setProperty("password", "*******");
Connection conn = DriverManager.getConnection(url, props);
String databaseProductVersion = conn.getMetaData().getDatabaseProductVersion();
System.out.println(databaseProductVersion);
}
我的
pg_hba.conf
:hostssl all all 192.168.0.0/16 scram-sha-256
#hostssl all all 192.168.0.0/16 trust
select rolname,rolpassword from pg_authid;
它显示: rolname | rolpassword

当我在 java 代码中使用
scram-sha-256
加密密码字符串或 prue 密码进行连接时,在日志文件中,它显示 FATAL: password authentication failed for user "pguser"
。当我在
trust
中将方法更改为 pg_hba.conf
时,它起作用了。如何使用
scram-sha-256
方法进行密码连接?我的 JDBC 驱动程序版本是
postgresql-42.2.12.jar
最佳答案
您必须提供明文密码,而不是 SCRAM 哈希。
