技术栈 : SpringBoot + shiro + jpa + freemark ，因为篇幅原因，这里只贴了部分代码说明，完整项目地址 : https://github.com/EalenXie/shiro-rbac-system
1 . 新建一个项目名为shiro-rbac-system，pom.xml加入基本依赖 :

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

基本的数据对象关系 :
一个用户对应一个或者多个角色。
一个角色对应一个或者多个权限。
一个权限对应能够访问对应的API或url资源。
1 . RBAC基本实体关系，Permission类(权限资源) :
/**
* Created by EalenXie on 2019/3/25 11:15.
* <p>
* 权限许可（Permission) 操作 及其能访问url 权限对应一个url地址
*/
@Entity
@Table(name = "system_shiro_permission")
public class Permission extends BaseEntity {
@Column(unique = true)
private String name; //权限名 唯一
@Column(unique = true)
private String url; //访问地址信息 唯一
private String description; //描述信息
//省略getter/setter
}
2 . Role类(用户角色)，一个角色拥有一个或者多个权限 :
/**
* Created by EalenXie on 2019/3/25 11:18.
* <p>
* 角色(Role) 角色下面对应多个权限
*/
@Entity
@Table(name = "system_shiro_role")
public class Role extends BaseEntity {
@Column(unique = true)
private String name; //角色名 唯一
private String description; //描述信息
@ManyToMany(fetch= FetchType.EAGER)
private List<Permission> permissions; //一个用户角色对应多个权限
//省略getter/setter
}
3 . User类(用户)，一个用户拥有一个或者多个角色 :
/**
* Created by EalenXie on 2019/3/25 11:01.
* <p>
* 用户表(User) 用户下面对应多个角色
*/
@Entity
@Table(name = "system_shiro_user")
public class User extends BaseEntity {
@Column(unique = true)
private String username;//用户名 唯一
private String password;//用户密码
private String passwordSalt;//用户密码加密盐值
@ManyToMany(fetch = FetchType.EAGER)
private List<Role> roles;//用户角色 一个用户可能有一个角色，也可能有 多个角色
//省略getter/setter
}
2 . 基本配置信息 :
1 . 配置应用的基本信息，application.yml :
server:
port: 8082
spring:
application:
name: shiro-rbac-system
resources:
static-locations: classpath:/
freemarker:
template-loader-path: classpath:/templates/
suffix: .html
content-type: text/html
charset: UTF-8
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/yourdatabase?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf-8&useSSL=true
username: yourname
password: yourpass
jpa:
# show-sql: true
hibernate:
ddl-auto: update
open-in-view: false # 禁用 OSIV <Spring Boot中默认启用了OSIV(Open Session in View)>
http:
encoding:
charset: utf-8
enabled: true
2 . 配置JPA，基本的数据库访问Dao。
public interface PermissionRepository extends JpaRepository<Permission, Integer> {
Permission findByName(String name);
}
public interface RoleRepository extends JpaRepository<Role, Integer> {
Role findByName(String name);
}
public interface UserRepository extends JpaRepository<User, Integer> {
User findByUsername(String username);
}
3 . 配置shiro，基于角色访问控制权限的核心Realm，UserAuthRealm :
@Component
public class UserAuthRealm extends AuthorizingRealm {
@Resource
private UserRepository userRepository;
/**
* 权限核心配置 根据数据库中的该用户 角色 和 权限
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
User user = (User) principals.getPrimaryPrincipal();
for (Role role : user.getRoles()) { //获取 角色
authorizationInfo.addRole(role.getName()); //添加 角色
for (Permission permission : role.getPermissions()) { //获取 权限
authorizationInfo.addStringPermission(permission.getName());//添加 权限
}
}
return authorizationInfo;
}
/**
* 用户登陆 凭证信息
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
String username = (String) token.getPrincipal();
User user = userRepository.findByUsername(username);
if (user == null) return null;
String credentials = user.getPasswordSalt() + user.getUsername() + user.getPasswordSalt();//自定义加盐 salt + username + salt
return new SimpleAuthenticationInfo(
user, //用户名
user.getPassword(), //密码
ByteSource.Util.bytes(credentials), //加密
getName() //realm name
);
}
/**
* 设置 realm的 HashedCredentialsMatcher
*/
@PostConstruct
public void setHashedCredentialsMatcher() {
this.setCredentialsMatcher(hashedCredentialsMatcher());
}
/**
* 凭证匹配 : 指定 加密算法,散列次数
*/
@Bean
public HashedCredentialsMatcher hashedCredentialsMatcher() {
HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher();
hashedCredentialsMatcher.setHashAlgorithmName("md5");//散列算法:这里使用MD5算法;
hashedCredentialsMatcher.setHashIterations(1024);//散列的次数，比如散列两次，相当于 md5(md5(""));
return hashedCredentialsMatcher;
}
}
4 . shiro核心配置,包含基本过滤器策略，注解支持等。
/**
* Created by EalenXie on 2019/3/25 15:12.
*/
@Configuration
public class ShiroConfig {
@Resource
private PermissionRepository permissionRepository;
@Resource
private UserAuthRealm userAuthRealm;
/**
* 配置 资源访问策略 . web应用程序 shiro核心过滤器配置
*/
@Bean
public ShiroFilterFactoryBean factoryBean(SecurityManager securityManager) {
ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();
factoryBean.setSecurityManager(securityManager);
factoryBean.setLoginUrl("/login");//登录页
factoryBean.setSuccessUrl("/index");//首页
factoryBean.setUnauthorizedUrl("/unauthorized");//未授权界面;
factoryBean.setFilterChainDefinitionMap(setFilterChainDefinitionMap()); //配置 拦截过滤器链
return factoryBean;
}
/**
* 配置 SecurityManager,可配置一个或多个realm
*/
@Bean
public SecurityManager securityManager() {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
securityManager.setRealm(userAuthRealm);
// securityManager.setRealm(xxxxRealm);
return securityManager;
}
/**
* 开启shiro 注解支持. 使以下注解能够生效 :
* 需要认证 {@link org.apache.shiro.authz.annotation.RequiresAuthentication RequiresAuthentication}
* 需要用户 {@link org.apache.shiro.authz.annotation.RequiresUser RequiresUser}
* 需要访客 {@link org.apache.shiro.authz.annotation.RequiresGuest RequiresGuest}
* 需要角色 {@link org.apache.shiro.authz.annotation.RequiresRoles RequiresRoles}
* 需要权限 {@link org.apache.shiro.authz.annotation.RequiresPermissions RequiresPermissions}
*/
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
return authorizationAttributeSourceAdvisor;
}
/**
* 配置 拦截过滤器链. map的键 : 资源地址 ; map的值 : 所有默认Shiro过滤器实例名
* 默认Shiro过滤器实例 参考 : {@link org.apache.shiro.web.filter.mgt.DefaultFilter}
*/
private Map<String, String> setFilterChainDefinitionMap() {
Map<String, String> filterMap = new LinkedHashMap<>();
//注册 数据库中所有的权限 及其对应url
List<Permission> allPermission = permissionRepository.findAll();//数据库中查询所有权限
for (Permission p : allPermission) {
filterMap.put(p.getUrl(), "perms[" + p.getName() + "]"); //拦截器中注册所有的权限
}
filterMap.put("/static/**", "anon"); //公开访问的资源
filterMap.put("/open/api/**", "anon"); //公开接口地址
filterMap.put("/logout", "logout"); //配置登出页,shiro已经帮我们实现了跳转
filterMap.put("/**", "authc"); //所有资源都需要经过验证
return filterMap;
}
}
5 . 用于授权相关注解进行测试的API RestController。AuthorizationApiFacade :
/**
* Created by EalenXie on 2019/3/26 16:46.
* 授权相关API 测试
*/
@RestController
public class AuthorizationApiFacade {
/**
* 需要 验证 才能访问的api
*/
@RequestMapping("/requiresAuthentication")
@RequiresAuthentication
public Map<String, String> requiresAuthentication() {
Map<String, String> result = new HashMap<>();
result.put("msg", "Require Authentication : 需要认证 测试, 能够访问此接口");
return result;
}
/**
* 需要 用户 身份才能访问的api
*/
@RequiresUser
@RequestMapping("/requiresUser")
public Map<String, String> requiresUser() {
Map<String, String> result = new HashMap<>();
result.put("msg", "Require User : 需要用户 测试, 能够访问此接口");
return result;
}
/**
* 需要 Guest 身份才能访问的api
*/
@RequiresGuest
@RequestMapping("/requiresGuest")
public Map<String, String> requiresGuest() {
Map<String, String> result = new HashMap<>();
result.put("msg", "Require Guest : 需要认证 测试, 能够访问此接口");
return result;
}
/**
* 需要 administrator 角色才能访问的api
*/
@RequiresRoles("administrator")
@RequestMapping("/requiresRoles")
public Map<String, String> requiresRoles() {
Map<String, String> result = new HashMap<>();
result.put("msg", "require Roles : 该用户具有 administrator 角色, 能够访问此接口");
return result;
}
/**
* 需要 add 权限才能访问的api
*/
@RequiresPermissions("add")
@RequestMapping("/requiresPermissionsAdd")
public Map<String, String> requiresPermissionsAdd() {
Map<String, String> result = new HashMap<>();
result.put("msg", "require Permissions : 该用户具有 add 权限 , 能够访问此接口");
return result;
}
/**
* 需要 delete 权限才能访问的api
*/
@RequiresPermissions("delete")
@RequestMapping("/requiresPermissionsDelete")
public Map<String, String> requiresPermissionsDelete() {
Map<String, String> result = new HashMap<>();
result.put("msg", "require Permissions : 该用户具有 delete 权限 , 能够访问此接口");
return result;
}
/**
* 公开接口
*/
@RequestMapping(value = "/open/api/sayHello", method = RequestMethod.POST)
public Map<String, String> sayHello() {
Map<String, String> result = new HashMap<>();
result.put("msg", "这个是公开接口,谁都可以访问");
return result;
}
}
进行测试，用户登陆(zhangsan)测试，zhangsan只具有user角色，只有部分权限。
登陆成功后，进入到首页。
访问，/add 则跳转到 新增页面
访问/delete，因为没有权限会跳转到未授权页面。
zhangsan只能调用自己拥有角色和权限的api :
没有相关角色和权限的api不能调用 :
