一,动态权限管理的优点和缺点
1,优点:
因为控制权限的数据保存在了mysql或其他存储系统中,
可以动态修改权限控制,无需改动代码和重启应用,
权限变更时灵活方便
2,缺点:
权限的设置需要保存在外部存储系统,
每次request时都需要查库处理,
高并发时影响效率

3,数据库:
建立各个表的sql:
CREATE TABLE `sys_user` (
`userId` int(11) NOT NULL AUTO_INCREMENT COMMENT 'id',
`userName` varchar(100) NOT NULL DEFAULT '' COMMENT '用户名',
`password` varchar(100) NOT NULL DEFAULT '' COMMENT '密码',
`nickName` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT '' COMMENT '昵称',
PRIMARY KEY (`userId`),
UNIQUE KEY `userName` (`userName`)
) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT='用户表'
INSERT INTO `sys_user` (`userId`, `userName`, `password`, `nickName`) VALUES
(1, 'lhd', '$2a$10$yGcOz3ekNI6Ya67tqQueS.raxyTOedGsv5jh2BwtRrI5/K9QEIPGq', '老刘'),
(2, 'admin', '$2a$10$yGcOz3ekNI6Ya67tqQueS.raxyTOedGsv5jh2BwtRrI5/K9QEIPGq', '管理员'),
(3, 'merchant', '$2a$10$yGcOz3ekNI6Ya67tqQueS.raxyTOedGsv5jh2BwtRrI5/K9QEIPGq', '商户老张');
CREATE TABLE `sys_user_role` (
`urId` int(11) NOT NULL AUTO_INCREMENT COMMENT 'id',
`userId` int(11) NOT NULL DEFAULT '0' COMMENT '用户id',
`roleName` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT '' COMMENT '角色id',
PRIMARY KEY (`urId`),
UNIQUE KEY `userId` (`userId`,`roleName`)
) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT='用户角色关联表'
INSERT INTO `sys_user_role` (`urId`, `userId`, `roleName`) VALUES
(1, 2, 'ADMIN'),
(2, 3, 'MERCHANT');
CREATE TABLE `sys_menu` (
`menuId` int(11) NOT NULL AUTO_INCREMENT,
`pattern` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci DEFAULT NULL,
PRIMARY KEY (`menuId`)
) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT='method'
INSERT INTO `sys_menu` (`menuId`, `pattern`) VALUES
(1, '/home/**'),
(2, '/login/**'),
(3, '/js/**'),
(4, '/admin/**'),
(5, '/merchant/**');
CREATE TABLE `sys_menu_role` (

`menuId` int(11) DEFAULT NULL,
`roleName` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci DEFAULT '' COMMENT 'role名字',

INSERT INTO `sys_menu_role` (`id`, `menuId`, `roleName`) VALUES
(1, 1, 'ALL'),
(2, 2, 'ALL'),
(3, 3, 'ALL'),
(4, 4, 'ADMIN'),
(5, 5, 'MERCHANT'),
(6, 5, 'ADMIN');
说明:sys_user表中,3个用户的密码都是111111,仅供演示使用,大家在生产环境中一定不要这样设置
四,java代码说明
1,WebSecurityConfig.java
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
private final static BCryptPasswordEncoder ENCODER = new BCryptPasswordEncoder();
@Resource
private UserLoginFailureHandler userLoginFailureHandler;//登录失败的处理类
@Resource
private UserLoginSuccessHandler userLoginSuccessHandler;//登录成功的处理类
@Resource
private UserLogoutSuccessHandler userLogoutSuccessHandler;//退出成功的处理类
@Resource
private UserAccessDeniedHandler userAccessDeniedHandler;//无权访问的处理类
@Resource
private SecUserDetailService secUserDetailService; //用户信息类,用来得到UserDetails
@Resource
private CustomFilterInvocationSecurityMetadataSource customFilterInvocationSecurityMetadataSource;
@Resource
private CustomAccessDecisionManager customAccessDecisionManager;
//指定加密的方式,避免出现:There is no PasswordEncoder mapped for the id "null"
@Bean
public PasswordEncoder passwordEncoder(){//密码加密类
return new BCryptPasswordEncoder();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
//通过数据库的配置,动态判断当前用户是否可以访问当前url
http.authorizeRequests()
.withObjectPostProcessor(new ObjectPostProcessor<FilterSecurityInterceptor>() {
@Override
public <O extends FilterSecurityInterceptor> O postProcess(O object) {
object.setSecurityMetadataSource(customFilterInvocationSecurityMetadataSource);
object.setAccessDecisionManager(customAccessDecisionManager);
return object;
}
});
//login
http.formLogin()
.loginPage("/login/login")
.loginProcessingUrl("/login/logined")//发送Ajax请求的路径
.usernameParameter("username")//请求验证参数
.passwordParameter("password")//请求验证参数
.failureHandler(userLoginFailureHandler)//验证失败处理
.successHandler(userLoginSuccessHandler)//验证成功处理
.permitAll(); //登录页面用户任意访问
//logout
http.logout()
.logoutUrl("/login/logout")
.logoutSuccessUrl("/login/logout")
.logoutSuccessHandler(userLogoutSuccessHandler)//登出处理
.deleteCookies("JSESSIONID")
.clearAuthentication(true)
.invalidateHttpSession(true)
.permitAll();
//其他任何请求,登录后可以访问
http.authorizeRequests().anyRequest().authenticated();
//accessdenied
http.exceptionHandling().accessDeniedHandler(userAccessDeniedHandler);//无权限时的处理
//user detail
http.userDetailsService(secUserDetailService);
}
@Resource
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(secUserDetailService).passwordEncoder(new PasswordEncoder() {
@Override
public String encode(CharSequence charSequence) {
return ENCODER.encode(charSequence);
}
//密码匹配,看输入的密码经过加密与数据库中存放的是否一样
@Override
public boolean matches(CharSequence charSequence, String s) {
return ENCODER.matches(charSequence,s);
}
});
}
}
2,CustomAccessDecisionManager.java
@Component
public class CustomAccessDecisionManager implements AccessDecisionManager {
//比较用户的权限和url所需要的权限,确定是否可以访问
@Override
public void decide(Authentication authentication, Object object, Collection<ConfigAttribute> configAttributes) throws AccessDeniedException, InsufficientAuthenticationException {
for (ConfigAttribute configAttribute : configAttributes) {
//如果是all,表示所有的都允许访问
if ("ALL".equals(configAttribute.getAttribute())) {
return;
}
//是否没有权限要求
if ("ROLE_def".equals(configAttribute.getAttribute())) {
if (authentication instanceof AnonymousAuthenticationToken) {
System.out.println("匿名用户");
throw new AccessDeniedException("权限不足,无法访问!");
} else {
System.out.println("其他类型用户,可以访问");
return;
}
}
Collection<? extends GrantedAuthority> authorities = authentication.getAuthorities();
for (GrantedAuthority authority : authorities) {
String userRole = authority.getAuthority();
//数据库中没有保存ROLE_,这里添加上
String menuRole = "ROLE_"+configAttribute.getAttribute();
if (userRole.equals(menuRole)) {
//System.out.println("进入应用系统");
return;
}
}
}
throw new AccessDeniedException("权限不足,无法访问!");
}
@Override
public boolean supports(ConfigAttribute attribute) {
return true;
}
@Override
public boolean supports(Class<?> clazz) {
return true;
}
}
用来判断当前用户是否有权限访问当前的url
3,CustomFilterInvocationSecurityMetadataSource.java
@Component
public class CustomFilterInvocationSecurityMetadataSource implements FilterInvocationSecurityMetadataSource {
AntPathMatcher pathMatcher = new AntPathMatcher();
@Autowired
private SysMenuService sysMenuService;
//得到所有的menu,
//查询出匹配当前url的所有role
@Override
public Collection<ConfigAttribute> getAttributes(Object object) throws IllegalArgumentException {
String requestUrl = ((FilterInvocation) object).getRequestUrl();
List<SysMenu> menus = sysMenuService.getMenus();
for (SysMenu menu : menus) {
if (pathMatcher.match(menu.getPattern(), requestUrl)) {
List<String> roles = menu.getRoles();
String[] roleStr = new String[roles.size()];
for (int i = 0; i < roles.size(); i++) {
roleStr[i] = roles.get(i);
}
return SecurityConfig.createList(roleStr);
}
}
return SecurityConfig.createList("ROLE_def");
}
@Override
public Collection<ConfigAttribute> getAllConfigAttributes() {
return null;
}
@Override
public boolean supports(Class<?> clazz) {
return true;
}
}
通过查询数据库得到匹配当前url的role
4,SecUser.java
public class SecUser extends User {
//用户id
private int userid;
//用户昵称
private String nickname;
public SecUser(String username, String password, Collection<? extends GrantedAuthority> authorities) {
super(username, password, authorities);
}
public SecUser(String username, String password, boolean enabled, boolean accountNonExpired, boolean credentialsNonExpired, boolean accountNonLocked, Collection<? extends GrantedAuthority> authorities) {
super(username, password, enabled, accountNonExpired, credentialsNonExpired, accountNonLocked, authorities);
}
public String getNickname() {
return nickname;
}
public void setNickname(String nickname) {
this.nickname = nickname;
}
public int getUserid() {
return userid;
}
public void setUserid(int userid) {
this.userid = userid;
}
}
spring security中User类的子类,增加了用户id和昵称,
需要保存到session中的信息,在这里扩展
目的是避免在每个页面上显示用户信息需要查数据库
5,SecUserDetailService.java
/**
* Created by liuhongdi on 2020/07/09.
*/
@Component("SecUserDetailService")
public class SecUserDetailService implements UserDetailsService{
@Resource
private SysUserService sysUserService;
@Override
public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
//查库
SysUser oneUser = sysUserService.getOneUserByUsername(s);//数据库查询 看用户是否存在
String encodedPassword = oneUser.getPassword();
Collection<GrantedAuthority> collection = new ArrayList<>();//权限集合
//用户权限:需要加 ROLE_
List<String> roles = oneUser.getRoles();
//System.out.println(roles);
for (String roleone : roles) {
GrantedAuthority grantedAuthority = new SimpleGrantedAuthority("ROLE_"+roleone);
collection.add(grantedAuthority);
}
//增加用户的userid,nickname
SecUser user = new SecUser(s,encodedPassword,collection);
user.setUserid(oneUser.getUserId());
user.setNickname(oneUser.getNickName());
return user;
}
}
6,UserAccessDeniedHandler.java
@Component("UserAccessDeniedHandler")
public class UserAccessDeniedHandler implements AccessDeniedHandler {
@Override
public void handle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse,
AccessDeniedException e) throws IOException, ServletException {
boolean isAjax = ServletUtil.isAjax();
//System.out.println("isajax:"+isAjax);
if (isAjax == true) {
ServletUtil.printRestResult(RestResult.error(ResponseCode.ACCESS_DENIED));
} else {
ServletUtil.printString(ResponseCode.ACCESS_DENIED.getMsg());
}
}
}
7,UserLoginFailureHandler.java
@Component("UserLoginFailureHandler")
public class UserLoginFailureHandler extends SimpleUrlAuthenticationFailureHandler {
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response,
AuthenticationException exception) throws IOException, ServletException {
//System.out.println("UserLoginFailureHandler");
ServletUtil.printRestResult(RestResult.error(ResponseCode.LOGIN_FAIL));
}
}
8,UserLoginSuccessHandler.java
@Component("UserLoginSuccessHandler")
public class UserLoginSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
//System.out.println("UserLoginSuccessHandler");
ServletUtil.printRestResult(RestResult.success(0,"登录成功"));
}
}
9,UserLogoutSuccessHandler.java
@Component("UserLogoutSuccessHandler")
public class UserLogoutSuccessHandler implements LogoutSuccessHandler{
@Override
public void onLogoutSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
httpServletRequest.getSession().invalidate();
ServletUtil.printRestResult(RestResult.success(0,"退出成功"));
}
}
10,WebInterceptor.java
@Component
public class WebInterceptor extends HandlerInterceptorAdapter {
//如果view不为空,把登录信息传递给模板
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) {
if (modelAndView != null) {
ModelMap modelMap = modelAndView.getModelMap();
SecUser currentUser = SessionUtil.getCurrentUser();
if (currentUser != null) {
modelMap.addAttribute("is_login","1");
modelMap.addAttribute("login_username",currentUser.getNickname());
} else {
modelMap.addAttribute("is_login","0");
modelMap.addAttribute("login_username","");
}
}
}
}
负责把传递页面公共部分显示的数据到模板

12,页面上用到的其他代码,可以移步github.com上查看
五,测试效果
1,访问首页:
http://127.0.0.1:8080/home/home
未登录时:
2,以普通用户lhd登录:
访问:管理员首页/商户首页,都会得到提示
无权访问
访问修改密码 页面,可以访问
3,以merchant用户登录:
role是MERCHANT
访问:管理员首页,提示:
无权访问
访问商户首页:可以访问
访问修改密码 页面,可以访问
4,以admin用户登录:
role是ADMIN
访问管理员首页:可以访问
访问商户首页:可以访问
访问修改密码 页面,可以访问
5,从mysql数据库sys_menu_role表中删除:meuid=5 rolename=ADMIN
这条记录,
则用admin登录后也不能再访问商户首页,
无权访问
无需重启应用
