xmpp with openfire之四 扩展的AuthProvider

上一篇中提到jdbcAuthProvider.passwordType提供了三种方式

如果你的密码加密规则不是这三种方式，可以自己进行扩充

首先，下载openfire的源码
http://www.igniterealtime.org/downloads/source.jsp

打开org.jivesoftware.openfire.auth.JDBCAuthProvider
Java代码

/**
* The JDBC auth provider allows you to authenticate users against any database
* that you can connect to with JDBC. It can be used along with the
* {@link HybridAuthProvider hybrid} auth provider, so that you can also have
* XMPP-only users that won't pollute your external data.<p>
*
* To enable this provider, set the following in the system properties:
* <ul>
* <li><tt>provider.auth.className = org.jivesoftware.openfire.auth.JDBCAuthProvider</tt></li>
* </ul>
*
* You'll also need to set your JDBC driver, connection string, and SQL statements:
*
* <ul>
* <li><tt>jdbcProvider.driver = com.mysql.jdbc.Driver</tt></li>
* <li><tt>jdbcProvider.connectionString = jdbc:mysql://localhost/dbname?user=username&password=secret</tt></li>
* <li><tt>jdbcAuthProvider.passwordSQL = SELECT password FROM user_account WHERE username=?</tt></li>
* <li><tt>jdbcAuthProvider.passwordType = plain</tt></li>
* <li><tt>jdbcAuthProvider.allowUpdate = true</tt></li>
* <li><tt>jdbcAuthProvider.setPasswordSQL = UPDATE user_account SET password=? WHERE username=?</tt></li>
* </ul>
*
* The passwordType setting tells Openfire how the password is stored. Setting the value
* is optional (when not set, it defaults to "plain"). The valid values are:<ul>
* <li>{@link PasswordType#plain plain}
* <li>{@link PasswordType#md5 md5}
* <li>{@link PasswordType#sha1 sha1}
* </ul>

看以看到通过读取PASSWORDTYPE配置
Java代码





JiveGlobals.migrateProperty("jdbcAuthProvider.passwordType"); 。。。。。 。。。。。 。。。。。 passwordType = PasswordType.plain; try { passwordType = PasswordType.valueOf( JiveGlobals.getProperty("jdbcAuthProvider.passwordType", "plain")); } catch (IllegalArgumentException iae) { Log.error(iae); }

JiveGlobals.migrateProperty("jdbcAuthProvider.passwordType");
。。。。。
。。。。。
。。。。。
passwordType = PasswordType.plain;
try {
passwordType = PasswordType.valueOf(
JiveGlobals.getProperty("jdbcAuthProvider.passwordType", "plain"));
}
catch (IllegalArgumentException iae) {
Log.error(iae);
}

进行密码的验证
Java代码





if (passwordType == PasswordType.md5) {
password = StringUtils.hash(password, "MD5");
}
else if (passwordType == PasswordType.sha1) {
password = StringUtils.hash(password, "SHA-1");
}
if (!password.equals(userPassword)) {
throw new UnauthorizedException();
}

if (passwordType == PasswordType.md5) {

}
else if (passwordType == PasswordType.sha1) {
password = StringUtils.hash(password, "SHA-1");
}
if (!password.equals(userPassword)) {
throw new UnauthorizedException();

编译后将此class加入到lib/openfire.jar中即可

当然不要忘记 将系统属性中
provider.auth.className,改成你自已的Provider
*上述代码例子中是org.yxsoft.openfire.plugin.BFMPAuthProvider
jdbcAuthProvider.passwordType，改成你自己定义的枚举值
*上述代码例子中是bfmp
