篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了007 整合spring相关的知识，希望对你有一定的参考价值。
一 .概述
在这里我们不去说shiro的web支持,我们直接进入spring的整合.然后再依次讲解shiro的一些特性.
二 .环境的配置

</init-param>
</filter>

<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
我们重点配置了一个shiro的过滤器.
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager"></property> <!-- 配置登录页面 --> <property name="loginUrl" value="/login"></property> <!-- 配置未授权页面的路径 --> <property name="unauthorizedUrl" value="/unan.jsp"></property> <!-- 配置登录成功的页面 --> <property name="successUrl" value="/WEB-INF/success.jsp"></property> <!-- 配置过滤器链 这是shiro的web配置的核心 --> <property name="filterChainDefinitions"> <value> /login=anon /js/**=anon /**=authc </value> </property> </bean> <!-- 配置安全管理器 --> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="realm" ref="realm"></property> <property name="cacheManager" ref="cacheManager"></property> </bean> <!-- 配置自定义的realm --> <bean id="realm" class="com.trek.realm.ShiroRealm"> </bean>
上面是shiro的核心配置.
我们可以看到我们重点配置了一个Filter.
然后shiro就是按照这个核心的过滤器完成整个权限的认证过程.
然后我们将之前的Shiro的SecurityManager设置到Shiro之中.
三 .核心代码
@ResponseBody @RequestMapping(value="/login",method=RequestMethod.POST) public Map<String,Object> checkUsernameAndPassword(String username ,String password) { //init Subject subject = SecurityUtils.getSubject(); UsernamePasswordToken token = new UsernamePasswordToken(username,password); //json Map<String,Object> json = new HashMap<String,Object>(); try { subject.login(token); //login json.put("status", Boolean.TRUE); } catch (AuthenticationException e) { logger.error("{}账号,密码为{}验证出现错误",username,password); json.put("status", Boolean.FALSE); json.put("msg", e.getMessage()); } return json ; }
public class ShiroRealm extends AuthorizingRealm{ private static final Logger logger = LoggerFactory.getLogger(ShiroRealm.class); @Autowired private UserDAO userdao; @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { UsernamePasswordToken utoken = (UsernamePasswordToken) token; String username = utoken.getUsername(); String password = new String(utoken.getPassword()); User user = userdao.selectUserByUsername(username); if(user == null) { throw new UnknownAccountException("账号不正确!"); } if(user.getLocked() == Boolean.TRUE) { throw new LockedAccountException("账号被锁定!"); } //密码校验 SimpleHash hash = new SimpleHash("MD5",username , user.getSalt(),1); if(!user.getPassword().equals(hash.toString())) { throw new IncorrectCredentialsException("密码不正确"); } SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user ,password ,getName() ); return info; } @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) { logger.info("开始授权....."); //从PrincipalCollection 中获取主体信息 //这个主体信息是认证时创建出来的. User user = (User) principals.getPrimaryPrincipal(); Integer userid = user.getId(); Set<Role> roles = userdao.selectAllRoleByUserId(userid); Set<Permission> pers = userdao.selectAllPermissionByUserId(userid); //创建返回信息 SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(); //设置角色信息 if(roles != null && roles.size()>0) { Set<String> roleStrings = new HashSet<String>(); for(Role role : roles) { roleStrings.add(role.getRolename()); } info.setRoles(roleStrings); } //设置权限信息 if(pers != null && pers.size()>0) { Set<String> perStrings = new HashSet<String>(); for(Permission per : pers) { perStrings.add(per.getPername()); } info.setStringPermissions(perStrings); } return info; }
至于表结构就是基本的RBAC表.
