/**
*
* Implementation of UserDatabase that persists {@link DefaultUserProfile}
* objects to a JDBC DataSource, as might typically be provided by a web
* container. 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 jspwiki.properties.
*
*
* Configurable properties are these:
*
*
*
* Property
* Default
* Definition
*
*
* jspwiki.userdatabase.datasourcejdbc/UserDatabaseThe JNDI name of the DataSource
*
*
* jspwiki.userdatabase.tableusersThe table that stores the user profiles
*
*
* jspwiki.userdatabase.attributesattributesThe CLOB column containing the profile's custom attributes, stored as key/value strings, each separated by newline.
*
*
* jspwiki.userdatabase.createdcreatedThe column containing the profile's creation timestamp
*
*
* jspwiki.userdatabase.emailemailThe column containing the user's e-mail address
*
*
* jspwiki.userdatabase.fullNamefull_nameThe column containing the user's full name
*
*
* jspwiki.userdatabase.loginNamelogin_nameThe column containing the user's login id
*
*
* jspwiki.userdatabase.passwordpasswordThe column containing the user's password
*
*
* jspwiki.userdatabase.modifiedmodifiedThe column containing the profile's last-modified timestamp
*
*
* jspwiki.userdatabase.uiduidThe column containing the profile's unique identifier, as a long integer
*
*
* jspwiki.userdatabase.wikiNamewiki_nameThe column containing the user's wiki name
*
*
* jspwiki.userdatabase.lockExpirylock_expiryThe column containing the date/time when the profile, if locked, should be unlocked.
*
*
* jspwiki.userdatabase.roleTablerolesThe 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).
*
*
* jspwiki.userdatabase.roleroleThe column in the role table that stores user roles. When a new user is
* created, this column will be populated with the value
* Authenticated. Once created, JDBCUserDatabase does not use
* this column again; it is provided strictly for the convenience of
* container-managed authentication services.
*
*
*
* 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.
*
*
* 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
* <Context ...>
* ...
* <Resource name="jdbc/UserDatabase" auth="Container"
* type="javax.sql.DataSource" username="dbusername" password="dbpassword"
* driverClassName="org.hsql.jdbcDriver" url="jdbc:HypersonicSQL:database"
* maxActive="8" maxIdle="4"/>
* ...
* </Context>
*
* 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.
*
*
* 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 lib
* directory. For more Tomcat JNDI configuration examples, see
* http://tomcat.apache.org/tomcat-7.0-doc/jndi-resources-howto.html.
* Once done, restart JSPWiki in the servlet container for it to read the
* new properties and switch to JDBC authentication.
*
*
* JDBCUserDatabase commits changes as transactions if the back-end database
* supports them. Changes are made immediately (during the {@link #save(UserProfile)} method).
*
*
* @since 2.3
