Shiro筆記（三）授權

一、授權方式

1.編程式:

1 Subject subject=SecurityUtils.getSubject(); 2 if(subject.hasRole("root")){ 3 //有權限 4 } else { 5 //無權限 6 }

2.注解式：

1 @RequiresRoles("admin") 2 public void hello(){ 3 //有權限才執行 4 }

3.JSP標簽：

1 <shiro:hasRole name="root"> 2 3 <!--有權限--> 4 </shiro:hasRole>

?

二、授權

1.基于角色的訪問控制

規則：用戶名=密碼，角色1，角色2......

shiro-role.ini文件：

1 [users] 2 tang=123,role1,role2 3 wang=321,role1

核心代碼：

1 /** 2 * @author Tang Jiujia 3 * @since 2017-10-16 4 */ 5 public class RoleTest extends BaseTest{ 6 7 @Test 8 public void testHasRole(){ 9 login("src/main/shiro-role.ini","tang","123"); 10 Subject subject= SecurityUtils.getSubject(); 11 Assert.assertTrue(subject.hasRole("role1")); 12 Assert.assertTrue(subject.hasAllRoles(Arrays.asList("role1","role2"))); 13 boolean[] hasRoles = subject.hasRoles(Arrays.asList("role1", "role2", "role3")); 14 15 for (int i=0;i<3;i++){ 16 if (hasRoles[i]==true){ 17 System.out.println("We have role"+(i+1)); 18 }else { 19 System.out.println("We don't have role"+(i+1)); 20 } 21 } 22 } 23 } 1 //checkRole與前面的hasRole不同的地方在于判斷為假時會拋UnauthorizedException 2 @Test(expected = UnauthorizedException.class) 3 public void testCheckRole(){ 4 login("src/main/shiro-role.ini","tang","123"); 5 Subject subject= SecurityUtils.getSubject(); 6 subject.checkRole("role1"); 7 subject.checkRoles("role1","role5"); 8 }

?

2.基于資源的訪問控制

規則：用戶名=密碼，角色1，角色2 ? ? ? ? ? ?角色=權限1，權限2

1 [users] 2 tang=123,role1,role2 3 wang=321,role2 4 [roles] 5 role1=root:create,root:add,root:update 6 role2=root:delete,root:update

核心代碼：

1 /** 2 * @author Tang Jiujia 3 * @since 2017-10-16 4 */ 5 public class PermissionTest extends BaseTest{ 6 7 @Test 8 public void testIsPermission(){ 9 login("src/main/shiro-permission.ini","tang","123456"); 10 Subject subject = SecurityUtils.getSubject(); 11 if (subject.isPermitted("root:add1")) { 12 System.out.println("have add"); 13 } else { 14 System.out.println("do not have add"); 15 } 16 if (subject.isPermitted("root:update")) System.out.println("Have update permission"); 17 } 18 19 @Test 20 public void testCheckPermission(){ 21 login("src/main/shiro-permission.ini","tang","123456"); 22 Subject subject = SecurityUtils.getSubject(); 23 subject.checkPermission("root:add"); 24 } 25 }
