apache shiro整合struts2+spring+mybatis简单demo

robin

先上一段shiro中获取数据源的代码，Demo见附件

public class AuthenticationRealm extends AuthorizingRealm {

    private static final Logger log = LoggerFactory.getLogger(AuthenticationRealm.class);
   
    @Autowired
private UserMapper userMapper;
   
    @Autowired
    private RoleMapper roleMapper;
   
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        UsernamePasswordToken upToken = (UsernamePasswordToken) token;
        String username = upToken.getUsername();
//        char[] password = upToken.getPassword();
//        log.debug(String.valueOf(password));
        // Null username is invalid
        if (username == null) {
            throw new AccountException("用户名不能为空!");
        }
        SimpleAuthenticationInfo info = null;
       try{
       String password =  userMapper.getPassword(username);
       if (password == null) {

           throw new AuthenticationException(message, e);
       }
