public class CustomRealm extends AuthorizingRealm {

// 第二步:根据用户输入的userCode从数据库查询
TAdminUser adminUser = adminUserService.getAdminUserByUserName(userName);
// 如果查询不到返回null
if (adminUser == null ) { //
return null ;
}
// 获取数据库中的密码
String password = adminUser.getPassword();
/**
* 认证的用户,正确的密码
*/
AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(adminUser, password, this .getName());
//MD5 加密+加盐+多次加密
//<span style="color:#ff0000;">SimpleAuthenticationInfo authcInfo = new SimpleAuthenticationInfo(adminUser, password,ByteSource.Util.bytes(salt), this.getName());</span>
return authcInfo;

/**
* 授权,只有成功通过<span style="font-family: Arial, Helvetica, sans-serif;">doGetAuthenticationInfo方法的认证后才会执行。</span>
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
// 从 principals获取主身份信息
// 将getPrimaryPrincipal方法返回值转为真实身份类型(在上边的doGetAuthenticationInfo认证通过填充到SimpleAuthenticationInfo中身份类型),
TAdminUser activeUser = (TAdminUser) principals.getPrimaryPrincipal();
// 根据身份信息获取权限信息
// 从数据库获取到权限数据
TAdminRole adminRoles = adminUserService.getAdminRoles(activeUser);
// 单独定一个集合对象
List<String> permissions = new ArrayList<String>();
if (adminRoles != null ) {
permissions.add(adminRoles.getRoleKey());
}
// 查到权限数据,返回授权信息(要包括 上边的permissions)
SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
// 将上边查询到授权信息填充到simpleAuthorizationInfo对象中
simpleAuthorizationInfo.addStringPermissions(permissions);
return simpleAuthorizationInfo;
}
// 清除缓存
public void clearCached() {
PrincipalCollection principals = SecurityUtils.getSubject().getPrincipals();
super .clearCache(principals);
}
}

5 缓存配置
ehcache.xml代码如下:
1

11
|
<ehcache updateCheck= "false" name= "shiroCache" >
<defaultCache
maxElementsInMemory= "10000"
eternal= "false"
timeToIdleSeconds= "120"
timeToLiveSeconds= "120"
overflowToDisk= "false"
diskPersistent= "false"
diskExpiryThreadIntervalSeconds= "120"
/>
</ehcache>
|
通过使用ehache中就避免第次都向服务器发送权限授权(doGetAuthorizationInfo)的请求。
6.自定义表单编码过滤器

public class CustomFormAuthenticationFilter extends FormAuthenticationFilter {
// 原FormAuthenticationFilter的认证方法
@Override
protected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws Exception {
// 在这里进行验证码的校验
// 从session获取正确验证码
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
HttpSession session = httpServletRequest.getSession();
// 取出session的验证码(正确的验证码)
String validateCode = (String) session.getAttribute( "validateCode" );
// 取出页面的验证码
// 输入的验证和session中的验证进行对比
String randomcode = httpServletRequest.getParameter( "randomcode" );
if (randomcode != null && validateCode != null && !randomcode.equals(validateCode)) {
// 如果校验失败,将验证码错误失败信息,通过shiroLoginFailure设置到request中
httpServletRequest.setAttribute( "shiroLoginFailure" , "randomCodeError" );
// 拒绝访问,不再校验账号和密码
return true ;
}
return super .onAccessDenied(request, response);
}
}

/**
* 到登录界面
*
* @return
* @throws Exception
*/
@RequestMapping ( "login.do" )
public String adminPage(HttpServletRequest request) throws Exception {
// 如果登陆失败从request中获取认证异常信息,shiroLoginFailure就是shiro异常类的全限定名
String exceptionClassName = (String) request.getAttribute( "shiroLoginFailure" );
// 根据shiro返回的异常类路径判断,抛出指定异常信息
if (exceptionClassName != null ) {
if (UnknownAccountException. class .getName().equals(exceptionClassName)) {
// 最终会抛给异常处理器
throw new CustomJsonException( "账号不存在" );
} else if (IncorrectCredentialsException. class .getName().equals(exceptionClassName)) {
throw new CustomJsonException( "用户名/密码错误" );
} else if ( "randomCodeError" .equals(exceptionClassName)) {
throw new CustomJsonException( "验证码错误 " );
} else {
throw new Exception(); // 最终在异常处理器生成未知错误
}
}
// 此方法不处理登陆成功(认证成功),shiro认证成功会自动跳转到上一个请求路径
// 登陆失败还到login页面
return "admin/login" ;
}
|
8.用户回显Controller
当用户登录认证成功后,CustomRealm在调用完doGetAuthenticationInfo时,通过
1
2
|
AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(adminUser, password, this .getName());
return authcInfo;
|
SimpleAuthenticationInfo构造参数的第一个参数传入一个用户的对象,之后,可通过Subject subject = SecurityUtils.getSubject();中的subject.getPrincipal()获取到此对象。所以需要回显用户信息时,我这样调用的
1
2
3
4
5
6
7
8
9
10
|
@RequestMapping ( "index.do" )
public String index(Model model) {
//从shiro的session中取activeUser
Subject subject = SecurityUtils.getSubject();
//取身份信息
TAdminUser adminUser = (TAdminUser) subject.getPrincipal();
//通过model传到页面
model.addAttribute( "adminUser" , adminUser);
return "admin/index" ;
}
|
9.在jsp页面中控制权限
先引入shiro的头文件
1
2
|
<!-- shiro头引入 -->
<%@ taglib uri= "http://shiro.apache.org/tags" prefix= "shiro" %>
|
采用shiro标签对权限进行处理
1
2
3
4
5
|
<!-- 有curd权限才显示修改链接,没有该 权限不显示,相当 于 if (hasPermission(curd)) -->
<shiro:hasPermission name= "curd" >
<BR />
我拥有超级的增删改查权限额
</shiro:hasPermission>
|
10.在Controller控制权限
通过@RequiresPermissions注解,指定执行此controller中某个请求方法需要的权限
1
2
3
|
@RequestMapping ( "/queryInfo.do" )
@RequiresPermissions ( "q" ) //执行需要"q"权限
public ModelAndView queryItems(HttpServletRequest request) throws Exception { }
|
11.MD5加密加盐处理
这里以修改密码为例,通过获取新的密码(明文)后通过MD5加密+加盐+3次加密为例
1

|
@RequestMapping ( "updatePassword.do" )
@ResponseBody
public String updateAdminUserPassword(String newPassword) {
// 从shiro的session中取activeUser
Subject subject = SecurityUtils.getSubject();
// 取身份信息
TAdminUser adminUser = (TAdminUser) subject.getPrincipal();
// 生成salt,随机生成
SecureRandomNumberGenerator secureRandomNumberGenerator = new SecureRandomNumberGenerator();
String salt = secureRandomNumberGenerator.nextBytes().toHex();
Md5Hash md5 = new Md5Hash(newPassword, salt, 3 );
String newMd5Password = md5.toHex();
// 设置新密码
adminUser.setPassword(newMd5Password);
// 设置盐
adminUser.setSalt(salt);
adminUserService.updateAdminUserPassword(adminUser);
return newPassword;
}
