自己根据shiro 源码捣鼓了一个shiro-spring ， 弄上来也给大家看看，其实只是对源码稍加修改，不知道怎么部署源码的同学可以看看，eclipse 项目。
一、在web.xml中添加shiro过滤器
<!-- Shiro Filter is defined in the spring application context: -->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<init-param>
<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
二、在applicationContext.xml 加入 shiro 配置，另外配置相关数据库连接
<?xml version="1.0" encoding="UTF-8"?>

/s/login = anon
# allow WebStart to pull the jars for the swing app:
/*.jar = anon
# everything else requires authentication:
/** = authc
</value>
</property>
</bean>
</beans>
三、实现JdbcRealm 重写认证方法，另外好像有几种不同Realm ，没细研究，有研究的同学可以补充下。
public class SaltAwareJdbcRealm extends JdbcRealm {
private static final Logger log = LoggerFactory.getLogger(SaltAwareJdbcRealm.class);
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
UsernamePasswordToken upToken = (UsernamePasswordToken) token;
String username = upToken.getUsername();
// Null username is invalid
if (username == null) {
throw new AccountException("Null usernames are not allowed by this realm.");
}
Connection conn = null;
AuthenticationInfo info = null;
try {
conn = dataSource.getConnection();
String password = getPasswordForUser(conn, username);
if (password == null) {
throw new UnknownAccountException("No account found for user [" + username + "]");
}
SimpleAuthenticationInfo saInfo = new SimpleAuthenticationInfo(username, password, getName());
/**
* This (very bad) example uses the username as the salt in this sample app. DON'T DO THIS IN A REAL APP!
*
* Salts should not be based on anything that a user could enter (attackers can exploit this). Instead
* they should ideally be cryptographically-strong randomly generated numbers.
*/
saInfo.setCredentialsSalt(ByteSource.Util.bytes(username));
info = saInfo;
} catch (SQLException e) {
final String message = "There was a SQL error while authenticating user [" + username + "]";
if (log.isErrorEnabled()) {
log.error(message, e);
}
// Rethrow any SQL errors as an authentication exception
throw new AuthenticationException(message, e);
} finally {
JdbcUtils.closeConnection(conn);
}
return info;
}
private String getPasswordForUser(Connection conn, String username) throws SQLException {
PreparedStatement ps = null;
ResultSet rs = null;
String password = null;
try {
ps = conn.prepareStatement(authenticationQuery);
ps.setString(1, username);
// Execute query
rs = ps.executeQuery();
// Loop over results - although we are only expecting one result, since usernames should be unique
boolean foundResult = false;
while (rs.next()) {
// Check to ensure only one row is processed
if (foundResult) {
throw new AuthenticationException("More than one user row found for user [" + username + "]. Usernames must be unique.");
}
password = rs.getString(1);
foundResult = true;
}
} finally {
JdbcUtils.closeResultSet(rs);
JdbcUtils.closeStatement(ps);
}
return password;
}
}
四、剩下的就是登录调用啦。
public class LoginController extends SimpleFormController {
private static transient final Logger log = LoggerFactory.getLogger(LoginController.class);
protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object cmd, BindException errors) throws Exception {
LoginCommand command = (LoginCommand) cmd;
UsernamePasswordToken token = new UsernamePasswordToken(command.getUsername(), command.getPassword());
try {
SecurityUtils.getSubject().login(token);
} catch (AuthenticationException e) {
log.debug("Error authenticating.", e);
errors.reject("error.invalidLogin", "The username or password was not correct.");
}
if (errors.hasErrors()) {
return showForm(request, response, errors);
} else {
return new ModelAndView(getSuccessView());
}
}
}
五、另外这个例子中还有一个通过Session来保存值的功能，通过key,value的方式来存的，登录之后大家可以看到。代码就不贴了，说白了就没什么意思了，大家自己看吧。
六、关于初始化数据
程序启动时有初始化数据代码，但是好像有点问题，而且没有判断是否存在，重启就报错了，在这里我就把SQL贴出来。
create table users ( username varchar(255) primary key, password varchar(255) not null); create table roles ( role_name varchar(255) primary key); create table user_roles ( username varchar(255) not null, role_name varchar(255) not null, constraint user_roles_uq unique ( username, role_name)); create table roles_permissions ( role_name varchar(255) not null, permission varchar(255) not null, primary key (role_name, permission)); 插入数据方法在 org.apache.shiro.samples.spring.BootstrapDataPopulator.afterPropertiesSet() 已经被我屏了，取消屏蔽，再启动 TOMCAT 之后。然后再屏掉吧。不然重启要出错。
关于包什么的，我截个图，大家自己导，难找的包我已经附上了。
