public class JdbcDaoImpl extends org.springframework.jdbc.core.support.JdbcDaoSupport implements UserDetailsService, org.springframework.context.MessageSourceAware
UserDetailsService implementation which retrieves the user details (username, password, enabled flag, and authorities) from a database using JDBC queries.

Default Schema

A default database schema is assumed, with two tables "users" and "authorities".

The Users table

This table contains the login name, password and enabled status of the user.
Column
username
password
enabled

The Authorities Table

Column
username
authority
If you are using an existing schema you will have to set the queries usersByUsernameQuery and authoritiesByUsernameQuery to match your database setup (see DEF_USERS_BY_USERNAME_QUERY and DEF_AUTHORITIES_BY_USERNAME_QUERY).

In order to minimise backward compatibility issues, this implementation doesn't recognise the expiration of user accounts or the expiration of user credentials. However, it does recognise and honour the user enabled/disabled column. This should map to a boolean type in the result set (the SQL type will depend on the database you are using). All the other columns map to Strings.

Group Support

Support for group-based authorities can be enabled by setting the enableGroups property to true (you may also then wish to set enableAuthorities to false to disable loading of authorities directly). With this approach, authorities are allocated to groups and a user's authorities are determined based on the groups they are a member of. The net result is the same (a UserDetails containing a set of GrantedAuthoritys is loaded), but the different persistence strategy may be more suitable for the administration of some applications.

When groups are being used, the tables "groups", "group_members" and "group_authorities" are used. See DEF_GROUP_AUTHORITIES_BY_USERNAME_QUERY for the default query which is used to load the group authorities. Again you can customize this by setting the groupAuthoritiesByUsernameQuery property, but the format of the rows returned should match the default.

    • getUsersByUsernameQuery

      public String getUsersByUsernameQuery()

    • initDao

      protected void initDao() throws org.springframework.context.ApplicationContextException
      Overrides:
      initDao in class org.springframework.dao.support.DaoSupport
      Throws:
      org.springframework.context.ApplicationContextException

    • loadUserByUsername

      public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException
      Description copied from interface: UserDetailsService
      Locates the user based on the username. In the actual implementation, the search may possibly be case sensitive, or case insensitive depending on how the implementation instance is configured. In this case, the UserDetails object that comes back may have a username that is of a different case than what was actually requested..
      Specified by:
      loadUserByUsername in interface UserDetailsService
      Parameters:
      username - the username identifying the user whose data is required.
      Returns:
      a fully populated user record (never null)
      Throws:
      UsernameNotFoundException - if the user could not be found or the user has no GrantedAuthority

    • loadUsersByUsername

      protected List<UserDetails> loadUsersByUsername(String username)
      Executes the SQL usersByUsernameQuery and returns a list of UserDetails objects. There should normally only be one matching user.

    • loadUserAuthorities

      protected List<GrantedAuthority> loadUserAuthorities(String username)
      Loads authorities by executing the SQL from authoritiesByUsernameQuery.
      Returns:
      a list of GrantedAuthority objects for the user

    • loadGroupAuthorities

      protected List<GrantedAuthority> loadGroupAuthorities(String username)
      Loads authorities by executing the SQL from groupAuthoritiesByUsernameQuery.
      Returns:
      a list of GrantedAuthority objects for the user

    • createUserDetails

      protected UserDetails createUserDetails(String username, UserDetails userFromUserQuery, List<GrantedAuthority> combinedAuthorities)
      Can be overridden to customize the creation of the final UserDetailsObject which is returned by the loadUserByUsername method.
      Parameters:
      username - the name originally passed to loadUserByUsername
      userFromUserQuery - the object returned from the execution of the
      combinedAuthorities - the combined array of authorities from all the authority loading queries.
      Returns:
      the final UserDetails which should be used in the system.

    • setAuthoritiesByUsernameQuery

      public void setAuthoritiesByUsernameQuery(String queryString)
      Allows the default query string used to retrieve authorities based on username to be overridden, if default table or column names need to be changed. The default query is DEF_AUTHORITIES_BY_USERNAME_QUERY; when modifying this query, ensure that all returned columns are mapped back to the same column positions as in the default query.
      Parameters:
      queryString - The SQL query string to set

    • getAuthoritiesByUsernameQuery

      protected String getAuthoritiesByUsernameQuery()

    • setGroupAuthoritiesByUsernameQuery

      public void setGroupAuthoritiesByUsernameQuery(String queryString)
      Allows the default query string used to retrieve group authorities based on username to be overridden, if default table or column names need to be changed. The default query is DEF_GROUP_AUTHORITIES_BY_USERNAME_QUERY; when modifying this query, ensure that all returned columns are mapped back to the same column positions as in the default query.
      Parameters:
      queryString - The SQL query string to set

    • setRolePrefix

      public void setRolePrefix(String rolePrefix)
      Allows a default role prefix to be specified. If this is set to a non-empty value, then it is automatically prepended to any roles read in from the db. This may for example be used to add the ROLE_ prefix expected to exist in role names (by default) by some other Spring Security classes, in the case that the prefix is not already present in the db.
      Parameters:
      rolePrefix - the new prefix

    • getRolePrefix

      protected String getRolePrefix()

    • setUsernameBasedPrimaryKey

      public void setUsernameBasedPrimaryKey(boolean usernameBasedPrimaryKey)
      If true (the default), indicates the getUsersByUsernameQuery() returns a username in response to a query. If false, indicates that a primary key is used instead. If set to true, the class will use the database-derived username in the returned UserDetails. If false, the class will use the loadUserByUsername(String) derived username in the returned UserDetails.
      Parameters:
      usernameBasedPrimaryKey - true if the mapping queries return the username String, or false if the mapping returns a database primary key.

    • isUsernameBasedPrimaryKey

      protected boolean isUsernameBasedPrimaryKey()

    • setUsersByUsernameQuery

      public void setUsersByUsernameQuery(String usersByUsernameQueryString)
      Allows the default query string used to retrieve users based on username to be overridden, if default table or column names need to be changed. The default query is DEF_USERS_BY_USERNAME_QUERY; when modifying this query, ensure that all returned columns are mapped back to the same column positions as in the default query. If the 'enabled' column does not exist in the source database, a permanent true value for this column may be returned by using a query similar to 
       "select username,password,'true' as enabled from users where username = ?"
      Parameters:
      usersByUsernameQueryString - The query string to set
