springmvc+shiro+maven 实现登录认证与权限授权管理
Shiro 是Shiro 是一个 Apache 下的一开源项目项目,旨在简化身份验证和授权。
1:shiro的配置,通过maven加入shiro相关jar包
2 :在web.xml中添加shiro过滤器
3: springmvc中对shiro配置

4 :自定义Realm编码
public class CustomRealm extends AuthorizingRealm {
// 设置realm的名称
@Override
public void setName(String name) {
super.setName("customRealm");
}
@Autowired
private AdminUserService adminUserService;
/**
* 认证
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
// token中包含用户输入的用户名和密码
// 第一步从token中取出用户名
String userName = (String) token.getPrincipal();
// 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
//SimpleAuthenticationInfo authcInfo = new SimpleAuthenticationInfo(adminUser, password,ByteSource.Util.bytes(salt), this.getName());
return authcInfo;
}
/**
* 授权,只有成功通过doGetAuthenticationInfo方法的认证后才会执行。
*/
@Override
jSCBmfprotected 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
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:
maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="false" diskPersistent="false" diskExpiryThreadIntervalSeconds="120" /> 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 CustomFormjSCBmfAuthenticationFilter代码,认证之前调用,可用于验证码校验 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); } } 在此符上验证码jsp界面的代码 validatecode.jsp <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ page import="java.util.Random"%> <%@ page import="java.io.OutputStream"%> <%@ page import="java.awt.Color"%> <%@ page import="java.awt.Font"%> <%@ page import="java.awt.Graphics"%> <%@ page import="java.awt.image.BufferedImage"%> <%@ page import="javax.imageio.ImageIO"%> <% int width = 60; int height = 32; //create the imagjSCBmfe BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); Graphics g = image.getGraphics(); // set the background color g.setColor(new Color(0xDCDCDC)); g.fillRect(0, 0, width, height); // draw the border g.setColor(Color.black); g.drawRect(0, 0, widthjSCBmf - 1, height - 1); // create a random instance to generate the codes Random rdm = new Random(); String hash1 = Integer.toHexString(rdm.nextInt()); // make some confusion for (int i = 0; i < 50; i++) { int x = rdm.nextInt(width); int y = rdm.nextInt(height); g.drawOval(x, y, 0, 0); } // generate a random code String capstr = hash1.substring(0, 4); //将生成的验证码存入session session.setAttribute("validateCode", capstr); g.setColor(new Color(0, 100, 0)); g.setFont(new Font("Candara", Font.BOLD, 24)); g.drawString(capstr, 8, 24); g.dispose(); //输出图片 response.setContentType("image/jpeg"); out.clear(); out = pageContext.pushBody(); OutputStream strm = response.getOutputStream(); ImageIO.write(image, "jpeg", strm); strm.close(); %> 7.登录控制器方法 /** * 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 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 @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 <%@ taglib uri="http://shiro.apache.org/tags" prefix="shiro"%> 采用shiro标签对权限进行处理 我拥有超级的增删改查权限额 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 @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 @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; } 总结 以上所述是给大家介绍的springmvc+shiro+maven 实现登录认证与权限授权管理,希望对大家有所帮助,如果大家有任何疑问请给我留言,会及时回复大家的。在此也非常感谢大家对我们网站的支持!
maxElementsInMemory="10000"
eternal="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
overflowToDisk="false"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="120"
/>
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
CustomFormjSCBmfAuthenticationFilter代码,认证之前调用,可用于验证码校验
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);
}
}
在此符上验证码jsp界面的代码 validatecode.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ page import="java.util.Random"%>
<%@ page import="java.io.OutputStream"%>
<%@ page import="java.awt.Color"%>
<%@ page import="java.awt.Font"%>
<%@ page import="java.awt.Graphics"%>
<%@ page import="java.awt.image.BufferedImage"%>
<%@ page import="javax.imageio.ImageIO"%>
<%
int width = 60;
int height = 32;
//create the imagjSCBmfe
BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
Graphics g = image.getGraphics();
// set the background color
g.setColor(new Color(0xDCDCDC));
g.fillRect(0, 0, width, height);
// draw the border
g.setColor(Color.black);
g.drawRect(0, 0, widthjSCBmf - 1, height - 1);
// create a random instance to generate the codes
Random rdm = new Random();
String hash1 = Integer.toHexString(rdm.nextInt());
// make some confusion
for (int i = 0; i < 50; i++) {
int x = rdm.nextInt(width);
int y = rdm.nextInt(height);
g.drawOval(x, y, 0, 0);
}
// generate a random code
String capstr = hash1.substring(0, 4);
//将生成的验证码存入session
session.setAttribute("validateCode", capstr);
g.setColor(new Color(0, 100, 0));
g.setFont(new Font("Candara", Font.BOLD, 24));
g.drawString(capstr, 8, 24);
g.dispose();
//输出图片
response.setContentType("image/jpeg");
out.clear();
out = pageContext.pushBody();
OutputStream strm = response.getOutputStream();
ImageIO.write(image, "jpeg", strm);
strm.close();
%>
7.登录控制器方法
/**
* 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
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
@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
<%@ taglib uri="http://shiro.apache.org/tags" prefix="shiro"%>
采用shiro标签对权限进行处理
我拥有超级的增删改查权限额
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
@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
@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;
}
总结
