需要有Spring的环境 ssj/项目
因为spring集成类shrio框架,所以导shiro和spring的集成包,如果要测试还是导上测试包,我这没导测试包
<!-- shiro(权限框架)的支持包 --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-all</artifactId> <version>1.4.0</version> <type>pom</type> </dependency> <!-- shiro与Spring的集成包 --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.4.0</version> </dependency>
3.2 web.xml
中配置代理过滤器<!-- shiro的过滤器(帮我们拦截请求)-》什么事情都不做 Delegating:授(权); 把(工作、权力等)委托(给下级); 选派(某人做某事) Proxy:代理 -> 需要通过名称(shiroFilter)去找真正的过滤器 --> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <init-param> <param-name>targetFilterLifecycle</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
public class MyRealm extends AuthorizingRealm { //授权认证功能就写在这里面 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { //获取授权对象 SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo(); //从getRoles()方法中获取角色并放且放到授权对象中,getRoles()方法在下面 Set<String> roles = getRoles(); authorizationInfo.setRoles(roles); //从getPerms()方法中获取权限并放且放到授权对象中,getPerms()方法在下面 Set<String> perms = getPerms(); authorizationInfo.setStringPermissions(perms); return authorizationInfo; } /** * 假设这里获取到当前用户的角色 */ private Set<String> getRoles(){ Set<String> roles = new HashSet<>(); roles.add("admin"); roles.add("it"); return roles; } /** * 假设这里获取到当前用户的权限 */ private Set<String> getPerms(){ Set<String> perms = new HashSet<>(); perms.add("employee:index"); return perms; } /** * 记住:如果这个方法返回null,就代表是用户名错误,shiro就会抛出:UnknownAccountException */ //身份认证(登录)就写在这里面 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { //1.拿到令牌(UsernamePasswordToken) UsernamePasswordToken token = (UsernamePasswordToken)authenticationToken; //2.拿到用户名,判断这个用户是否存在 // 2.1 拿到传过来的用户名 String username = token.getUsername(); // 2.2 根据用户名从getUsers()方法中拿到密码,getUsers()方法在下面 String password = this.getUsers(username); // 2.3 如果没有拿到密码(没有通过用户名拿到相应的用户->用户不存在) if(password==null){ return null; } //记住:我们只在正常完成这里的功能,shiro会判断密码是否正确 //3.返回 AuthenticationInfo这个对象 /** * 咱们创建对象需要传的参数:SimpleAuthenticatinInof(4个参数顺序解释) * Object principal:主体(可以乱写) -> 登录成功后,你想把哪一个对象存下来 * Object credentials:凭证(就是密码) -> 数据库中的密码 * credentials(密码)Salt:盐值 * String realmName : realm的名称(可以乱写) */ //拿到咱们的盐值对象(ByteSource) ByteSource salt = ByteSource.Util.bytes("itsource"); SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(username,password,salt,"myRealm"); return authenticationInfo; } /** * 假设这里是根据用户名进行的查询 * MD5:e10adc3949ba59abbe56e057f20f883e * MD5+10次:4a95737b032e98a50c056c41f2fa9ec6 * MD5+10次+itsource:831d092d59f6e305ebcfa77e05135eac */ public String getUsers(String username){ if("admin".equals(username)){ return "831d092d59f6e305ebcfa77e05135eac"; }else if("zhang".equals(username)){ return "123"; } return null; } }
/** * 用于返回下面的这些值(这里的值是有顺序的:LinkedHashMap) * <value> /login = anon /s/permission.jsp = perms[user:index] /** = authc </value> 这里修改后要重新启动tomcat */ public class ShiroFilterMapFactory { public Map<String,String> createMap(){ Map<String,String> map = new LinkedHashMap<>(); //anon:需要放行的路径 map.put("/login","anon"); //perms:权限拦截 map.put("/s/permission.jsp","perms[employee:index]"); //authc:拦截 map.put("/**","authc"); return map; } }
applicationContext-shiro.xml
的配置applicationContext.xml
中引入它 <import resource="classpath:applicationContext-shiro.xml" />
