• Shiro与Spring整合


    Shiro引入Spring

           添加jar包/maven配置

    添加spring-shiro.xml配置文件

          <property name="securityManager" ref="securityManager"/>

    </beans>

    自定义Realm类MyRealm.java

    public class MyRealm extends AuthorizingRealm{

        @Resource

        private UserService userService;

        /**

         * 为当限前登录的用户授予角色和权

         */

        @Override

        protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {

           String userName=(String)principals.getPrimaryPrincipal();

           SimpleAuthorizationInfo authorizationInfo=new SimpleAuthorizationInfo();

           authorizationInfo.setRoles(userService.getRoles(userName));

           authorizationInfo.setStringPermissions(userService.getPermissions(userName));

           return authorizationInfo;

        }

        /**

         * 验证当前登录的用户

         */

        @Override

        protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {

           String userName=(String)token.getPrincipal();

               User user=userService.getByUserName(userName);

               if(user!=null){

                  AuthenticationInfo authcInfo=new SimpleAuthenticationInfo(user.getUserName(),user.getPassword(),"xx");

                  return authcInfo;

               }else{

                  return null;            

               }

        }

    }

    自定义角色过滤器AnyOfRolesAuthorizationFilter.java

           当一个角色有多个功能模块页面的权限时,会出现权限失效问题,无法配置,需要自己定义角色过滤器。

    public class AnyOfRolesAuthorizationFilter extends RolesAuthorizationFilter{

        @Override

        public boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue)

               throws IOException {

           Subject subject = getSubject(request, response);

            String[] rolesArray = (String[]) mappedValue;

            if (rolesArray == null || rolesArray.length == 0) {

                return true;

            }

            for (String roleName : rolesArray) {

                if (subject.hasRole(roleName)) {

                    return true;

                }

            }

           return false;

        }

    }
