This implementation looks up the JDBC DataSource using JNDI. The * JNDI name of the datasource, backing table and mapped columns used by this * class can be overridden by adding settings in <code>jspwiki.properties</code>. * </p> * <p> * Configurable properties are these: * </p> * <table> * <tr> <thead> * <th>Property</th> * <th>Default</th> * <th>Definition</th> * <thead> </tr> * <tr> * <td><code>jspwiki.userdatabase.datasource</code></td> * <td><code>jdbc/UserDatabase</code></td> * <td>The JNDI name of the DataSource</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.table</code></td> * <td><code>users</code></td> * <td>The table that stores the user profiles</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.attributes</code></td> * <td><code>attributes</code></td> * <td>The CLOB column containing the profile's custom attributes, stored as key/value strings, each separated by newline.</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.created</code></td> * <td><code>created</code></td> * <td>The column containing the profile's creation timestamp</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.email</code></td> * <td><code>email</code></td> * <td>The column containing the user's e-mail address</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.fullName</code></td> * <td><code>full_name</code></td> * <td>The column containing the user's full name</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.loginName</code></td> * <td><code>login_name</code></td> * <td>The column containing the user's login id</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.password</code></td> * <td><code>password</code></td> * <td>The column containing the user's password</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.modified</code></td> * <td><code>modified</code></td> * <td>The column containing the profile's last-modified timestamp</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.uid</code></td> * <td><code>uid</code></td> * <td>The column containing the profile's unique identifier, as a long integer</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.wikiName</code></td> * <td><code>wiki_name</code></td> * <td>The column containing the user's wiki name</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.lockExpiry</code></td> * <td><code>lock_expiry</code></td> * <td>The column containing the date/time when the profile, if locked, should be unlocked.</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.roleTable</code></td> * <td><code>roles</code></td> * <td>The table that stores user roles. When a new user is created, a new * record is inserted containing user's initial role. The table will have an ID * column whose name and values correspond to the contents of the user table's * login name column. It will also contain a role column (see next row).</td> * </tr> * <tr> * <td><code>jspwiki.userdatabase.role</code></td> * <td><code>role</code></td> * <td>The column in the role table that stores user roles. When a new user is * created, this column will be populated with the value * <code>Authenticated</code>. Once created, JDBCUserDatabase does not use * this column again; it is provided strictly for the convenience of * container-managed authentication services.</td> * </tr> * </table> * <p> * This class hashes passwords using SHA-1. All of the underying SQL commands * used by this class are implemented using prepared statements, so it is immune * to SQL injection attacks. * </p> * <p> * This class is typically used in conjunction with a web container's JNDI * resource factory. For example, Tomcat provides a basic * JNDI factory for registering DataSources. To give JSPWiki access to the JNDI * resource named by <code></code>, you would declare the datasource resource * similar to this: * </p> * <blockquote><code><Context ...><br/> * ...<br/> * <Resource name="jdbc/UserDatabase" auth="Container"<br/> * type="javax.sql.DataSource" username="dbusername" password="dbpassword"<br/> * driverClassName="org.hsql.jdbcDriver" url="jdbc:HypersonicSQL:database"<br/> * maxActive="8" maxIdle="4"/><br/> * ...<br/> * </Context></code></blockquote> * <p> * To configure JSPWiki to use JDBC support, first create a database * with a structure similar to that provided by the HSQL and PostgreSQL * scripts in src/main/config/db. If you have different table or column * names you can either alias them with a database view and have JSPWiki * use the views, or alter the WEB-INF/jspwiki.properties file: the * jspwiki.userdatabase.* and jspwiki.groupdatabase.* properties change the * names of the tables and columns that JSPWiki uses. * </p> * <p> * A JNDI datasource (named jdbc/UserDatabase by default but can be configured * in the jspwiki.properties file) will need to be created in your servlet container. * JDBC driver JARs should be added, e.g. in Tomcat's <code>lib</code> * directory. For more Tomcat JNDI configuration examples, see <a * href="http://tomcat.apache.org/tomcat-7.0-doc/jndi-resources-howto.html"> * http://tomcat.apache.org/tomcat-7.0-doc/jndi-resources-howto.html</a>. * Once done, restart JSPWiki in the servlet container for it to read the * new properties and switch to JDBC authentication. * </p> * <p> * JDBCUserDatabase commits changes as transactions if the back-end database * supports them. If the database supports transactions, user profile changes * are saved to permanent storage only when the {@link #commit()} method is * called. If the database does <em>not</em> support transactions, then * changes are made immediately (during the {@link #save(UserProfile)} method), * and the {@linkplain #commit()} method no-ops. Thus, callers should always * call the {@linkplain #commit()} method after saving a profile to guarantee * that changes are applied. * </p> * * @since 2.3 */ public class JDBCUserDatabase extends AbstractUserDatabase { private static final String NOTHING = ""; public static final String DEFAULT_DB_ATTRIBUTES = "attributes"; public static final String DEFAULT_DB_CREATED = "created"; public static final String DEFAULT_DB_EMAIL = "email"; public static final String DEFAULT_DB_FULL_NAME = "full_name"; public static final String DEFAULT_DB_JNDI_NAME = "jdbc/UserDatabase"; public static final String DEFAULT_DB_LOCK_EXPIRY = "lock_expiry"; public static final String DEFAULT_DB_MODIFIED = "modified"; public static final String DEFAULT_DB_ROLE = "role"; public static final String DEFAULT_DB_ROLE_TABLE = "roles"; public static final String DEFAULT_DB_TABLE = "users"; public static final String DEFAULT_DB_LOGIN_NAME = "login_name"; public static final String DEFAULT_DB_PASSWORD = "password"; public static final String DEFAULT_DB_UID = "uid"; public static final String DEFAULT_DB_WIKI_NAME = "wiki_name"; public static final String PROP_DB_ATTRIBUTES = "jspwiki.userdatabase.attributes"; public static final String PROP_DB_CREATED = "jspwiki.userdatabase.created"; public static final String PROP_DB_EMAIL = "jspwiki.userdatabase.email"; public static final String PROP_DB_FULL_NAME = "jspwiki.userdatabase.fullName"; public static final String PROP_DB_DATASOURCE = "jspwiki.userdatabase.datasource"; public static final String PROP_DB_LOCK_EXPIRY = "jspwiki.userdatabase.lockExpiry"; public static final String PROP_DB_LOGIN_NAME = "jspwiki.userdatabase.loginName"; public static final String PROP_DB_MODIFIED = "jspwiki.userdatabase.modified"; public static final String PROP_DB_PASSWORD = "jspwiki.userdatabase.password"; public static final String PROP_DB_UID = "jspwiki.userdatabase.uid"; public static final String PROP_DB_ROLE = "jspwiki.userdatabase.role"; public static final String PROP_DB_ROLE_TABLE = "jspwiki.userdatabase.roleTable"; public static final String PROP_DB_TABLE = "jspwiki.userdatabase.table"; public static final String PROP_DB_WIKI_NAME = "jspwiki.userdatabase.wikiName"; private DataSource m_ds = null; private String m_deleteUserByLoginName = null; private String m_deleteRoleByLoginName = null; private String m_findByEmail = null; private String m_findByFullName = null; private String m_findByLoginName = null; private String m_findByUid = null; private String m_findByWikiName = null; private String m_renameProfile = null; private String m_renameRoles = null; private String m_updateProfile = null; private String m_findAll = null; private String m_findRoles = null; private String m_insertProfile = null; private String m_insertRole = null; private String m_attributes = null; private String m_email = null; private String m_fullName = null; private String m_lockExpiry = null; private String m_loginName = null; private String m_password = null; private String m_uid = null; private String m_wikiName = null; private String m_created = null; private String m_modified = null; private boolean m_supportsCommits = false; /** * Looks up and deletes the first {@link UserProfile} in the user database * that matches a profile having a given login name.
