在上面的配置中每次开启了sessionManager都会出问题在这里将它注释掉了。
其次，上面中的配置也是将credentialsMatcher没有加入了，这种方式适用于没有对密码进行处理的情况。
其中CustomRealm的配置是重点。
4 自定义Realm编码
CustomRealm如下：
1 public class CustomRealm extends AuthorizingRealm {
2 // 设置realm的名称
3 @Override
4 public void setName(String name) {
5 super.setName(“customRealm”);
6 }
7
8 @Autowired
9 private AdminUserService adminUserService; 10
11 /** 12 * 认证 13 */ 14 @Override 15 protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { 16
17 // token中包含用户输入的用户名和密码 18 // 第一步从token中取出用户名 19 String userName = (String) token.getPrincipal(); 20 // 第二步：根据用户输入的userCode从数据库查询 21 TAdminUser adminUser = adminUserService.getAdminUserByUserName(userName); 22 // 如果查询不到返回null 23 if (adminUser == null) {// 24 return null; 25 } 26 // 获取数据库中的密码 27 String password = adminUser.getPassword(); 28 /** 29 * 认证的用户,正确的密码 30 */ 31 AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(adminUser, password, this.getName()); 32 //MD5 加密+加盐+多次加密 33 //<span style=“color:#ff0000;”>SimpleAuthenticationInfo authcInfo = new SimpleAuthenticationInfo(adminUser, password,ByteSource.Util.bytes(salt), this.getName());</span>
34 return authcInfo; 35 } 36
37 /** 38 * 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>
39 */ 40 @Override 41 protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) { 42 // 从 principals获取主身份信息 43 // 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）， 44 TAdminUser activeUser = (TAdminUser) principals.getPrimaryPrincipal(); 45 // 根据身份信息获取权限信息 46 // 从数据库获取到权限数据 47 TAdminRole adminRoles = adminUserService.getAdminRoles(activeUser); 48 // 单独定一个集合对象 49 List<String> permissions = new ArrayList<String>(); 50 if (adminRoles != null) { 51 permissions.add(adminRoles.getRoleKey()); 52 } 53 // 查到权限数据，返回授权信息(要包括 上边的permissions) 54 SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo(); 55 // 将上边查询到授权信息填充到simpleAuthorizationInfo对象中 56 simpleAuthorizationInfo.addStringPermissions(permissions); 57 return simpleAuthorizationInfo; 58 } 59
60 // 清除缓存 61 public void clearCached() { 62 PrincipalCollection principals = SecurityUtils.getSubject().getPrincipals(); 63 super.clearCache(principals); 64 } 65 }
5 缓存配置
ehcache.xml代码如下：
1 <ehcache updateCheck=“false” name=“shiroCache”>
2 <defaultCache
3 maxElementsInMemory=“10000”
4 eternal=“false”
5 timeToIdleSeconds=“120”
6 timeToLiveSeconds=“120”
7 overflowToDisk=“false”
8 diskPersistent=“false”
9 diskExpiryThreadIntervalSeconds=“120”
10 />
11 </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
CustomFormAuthenticationFilter代码，认证之前调用，可用于验证码校验
1 public class CustomFormAuthenticationFilter extends FormAuthenticationFilter {
2 // 原FormAuthenticationFilter的认证方法
3 @Override
4 protected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws Exception {
5 // 在这里进行验证码的校验
6
7 // 从session获取正确验证码
8 HttpServletRequest httpServletRequest = (HttpServletRequest) request;
9 HttpSession session = httpServletRequest.getSession(); 10 // 取出session的验证码（正确的验证码） 11 String validateCode = (String) session.getAttribute(“validateCode”); 12
13 // 取出页面的验证码 14 // 输入的验证和session中的验证进行对比 15 String randomcode = httpServletRequest.getParameter(“randomcode”); 16 if (randomcode != null && validateCode != null && !randomcode.equals(validateCode)) { 17 // 如果校验失败，将验证码错误失败信息，通过shiroLoginFailure设置到request中 18 httpServletRequest.setAttribute(“shiroLoginFailure”, “randomCodeError”); 19 // 拒绝访问，不再校验账号和密码 20 return true; 21 } 22 return super.onAccessDenied(request, response); 23 } 24 }
在此符上验证码jsp界面的代码
validatecode.jsp
1 <%@ page language=“java” contentType=“text/html; charset=UTF-8”
2 pageEncoding=“UTF-8”%>
3 <%@ page import=“java.util.Random”%>
4 <%@ page import=“java.io.OutputStream”%>
5 <%@ page import=“java.awt.Color”%>
6 <%@ page import=“java.awt.Font”%>
7 <%@ page import=“java.awt.Graphics”%>
8 <%@ page import=“java.awt.image.BufferedImage”%>
9 <%@ page import=“javax.imageio.ImageIO”%>
10 <% 11 int width = 60; 12 int height = 32; 13 //create the image 14 BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); 15 Graphics g = image.getGraphics(); 16 // set the background color 17 g.setColor(new Color(0xDCDCDC)); 18 g.fillRect(0, 0, width, height); 19 // draw the border 20 g.setColor(Color.black); 21 g.drawRect(0, 0, width - 1, height - 1); 22 // create a random instance to generate the codes 23 Random rdm = new Random(); 24 String hash1 = Integer.toHexString(rdm.nextInt()); 25 // make some confusion 26 for (int i = 0; i < 50; i++) { 27 int x = rdm.nextInt(width); 28 int y = rdm.nextInt(height); 29 g.drawOval(x, y, 0, 0); 30 } 31 // generate a random code 32 String capstr = hash1.substring(0, 4); 33 //将生成的验证码存入session 34 session.setAttribute(“validateCode”, capstr); 35 g.setColor(new Color(0, 100, 0)); 36 g.setFont(new Font(“Candara”, Font.BOLD, 24)); 37 g.drawString(capstr, 8, 24); 38 g.dispose(); 39 //输出图片 40 response.setContentType(“image/jpeg”); 41 out.clear(); 42 out = pageContext.pushBody(); 43 OutputStream strm = response.getOutputStream(); 44 ImageIO.write(image, “jpeg”, strm); 45 strm.close(); 46 %>
7.登录控制器方法
1 /**
2 * 到登录界面
3 *
4 * @return
5 * @throws Exception 6 */
7 @RequestMapping(“login.do”)
8 public String adminPage(HttpServletRequest request) throws Exception { 9 // 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
10 String exceptionClassName = (String) request.getAttribute(“shiroLoginFailure”); 11 // 根据shiro返回的异常类路径判断，抛出指定异常信息
12 if (exceptionClassName != null) { 13 if (UnknownAccountException.class.getName().equals(exceptionClassName)) { 14 // 最终会抛给异常处理器
15 throw new CustomJsonException(“账号不存在”); 16 } else if (IncorrectCredentialsException.class.getName().equals(exceptionClassName)) { 17 throw new CustomJsonException(“用户名/密码错误”); 18 } else if (“randomCodeError”.equals(exceptionClassName)) { 19 throw new CustomJsonException(“验证码错误 “); 20 } else { 21 throw new Exception();// 最终在异常处理器生成未知错误
22 } 23 } 24 // 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 25 // 登陆失败还到login页面
26 return “admin/login”; 27 }
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 AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(adminUser, password, this.getName()); 2 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 @RequestMapping(“index.do”)
2 public String index(Model model) { 3 //从shiro的session中取activeUser
4 Subject subject = SecurityUtils.getSubject(); 5 //取身份信息
6 TAdminUser adminUser = (TAdminUser) subject.getPrincipal(); 7 //通过model传到页面
8 model.addAttribute(“adminUser”, adminUser);
9 return “admin/index”; 10 }
9.在jsp页面中控制权限
先引入shiro的头文件
1 2 <%@ taglib uri=”http://shiro.apache.org/tags“ prefix=”shiro”%>
采用shiro标签对权限进行处理
1
2 <shiro:hasPermission name=”curd”>
3
4 我拥有超级的增删改查权限额 5
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 @RequestMapping(“/queryInfo.do”) 2 @RequiresPermissions(“q”)//执行需要”q”权限
3 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+6次加密为例
1 @RequestMapping(“updatePassword.do”)
2 @ResponseBody
3 public String updateAdminUserPassword(String newPassword) { 4 // 从shiro的session中取activeUser
5 Subject subject = SecurityUtils.getSubject(); 6 // 取身份信息
7 TAdminUser adminUser = (TAdminUser) subject.getPrincipal(); 8 // 生成salt,随机生成
9 SecureRandomNumberGenerator secureRandomNumberGenerator = new SecureRandomNumberGenerator(); 10 String salt = secureRandomNumberGenerator.nextBytes().toHex(); 11 Md5Hash md5 = new Md5Hash(newPassword, salt, 6); 12 String newMd5Password = md5.toHex(); 13 // 设置新密码
14 adminUser.setPassword(newMd5Password); 15 // 设置盐
16 adminUser.setSalt(salt); 17 adminUserService.updateAdminUserPassword(adminUser); 18 return newPassword; 19 }
ok!编码完成后对此WEB程序跑一下，截图符几张：
