• springboot整合shiro应用


    1、Shiro是Apache下的一个开源项目,我们称之为Apache Shiro。它是一个很易用与Java项目的的安全框架,提供了认证、授权、加密、会话管理,与spring Security 一样都是做一个权限的安全框架,但是与Spring Security 相比,在于 Shiro 使用了比较简单易懂易于使用的授权方式。shiro属于轻量级框架,相对于security简单的多,也没有security那么复杂。所以我这里也是简单介绍一下shiro的使用。

    2、非常简单;其基本功能点如下图所示:

     

    Authentication身份认证/登录,验证用户是不是拥有相应的身份;

    Authorization授权,即权限验证,验证某个已认证的用户是否拥有某个权限;即判断用户是否能做事情,常见的如:验证某个用户是否拥有某个角色。或者细粒度的验证某个用户对某个资源是否具有某个权限;

    Session Manager会话管理,即用户登录后就是一次会话,在没有退出之前,它的所有信息都在会话中;会话可以是普通JavaSE环境的,也可以是如Web环境的;

    Cryptography加密,保护数据的安全性,如密码加密存储到数据库,而不是明文存储;

    Web SupportWeb支持,可以非常容易的集成到Web环境;

    Caching:缓存,比如用户登录后,其用户信息、拥有的角色/权限不必每次去查,这样可以提高效率;

    Concurrencyshiro支持多线程应用的并发验证,即如在一个线程中开启另一个线程,能把权限自动传播过去;

    Testing提供测试支持;

    Run As允许一个用户假装为另一个用户(如果他们允许)的身份进行访问;

    Remember Me记住我,这个是非常常见的功能,即一次登录后,下次再来的话不用登录了。

    记住一点,Shiro不会去维护用户、维护权限;这些需要我们自己去设计/提供;然后通过相应的接口注入给Shiro即可。

    3、这里我就简单介绍一下springboot和shiro整合与基本使用。

      1)目录结构

      2)需要的基础包:pom.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            <dependency>

            </dependency>
        </dependencies>
    
    </project>

      3)基本配置application.yml  

    server:
      port: 8082
    spring:
      datasource:
        driver-class-name: com.mysql.jdbc.Driver
        url: jdbc:mysql://localhost:3306/spring_shiro?useUnicode=true&amp;characterEncoding=UTF-8
        username: root
        password: root
        type: com.alibaba.druid.pool.DruidDataSource
      jpa:
        show-sql: true
        hibernate:
          ddl-auto: update
      http:
        encoding:
          charset: utf-8
          enabled: true

      4)这里我们基本需要3个实体,用户,角色和权限

      (1)角色:User.class

    @Entity
    public class User {
    
        @Id
        @GeneratedValue(strategy = GenerationType.AUTO)
        private Long id;
        @Column(unique = true)
        private String name;
        private Integer password;
        @OneToMany(cascade = CascadeType.ALL,mappedBy = "user")
        private List<Role> roles;
    
        public Long getId() {
            return id;
        }
    
        public void setId(Long id) {
            this.id = id;
        }
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public List<Role> getRoles() {
            return roles;
        }
    
        public void setRoles(List<Role> roles) {
            this.roles = roles;
        }
    
        public Integer getPassword() {
            return password;
        }
    
        public void setPassword(Integer password) {
            this.password = password;
        }
    }

      注:这里我只考虑一个用户对多个角色,不考虑多对多的关系

      (2)角色:Role.class

    @Entity
    public class Role {
    
        @Id
        @GeneratedValue(strategy = GenerationType.AUTO)
        private Long id;
        private String roleName;
        @ManyToOne(fetch = FetchType.EAGER)
        private User user;
        @OneToMany(cascade = CascadeType.ALL,mappedBy = "role")
        private List<Permission> permissions;
    
        public Long getId() {
            return id;
        }
    
        public void setId(Long id) {
            this.id = id;
        }
    
        public String getRoleName() {
            return roleName;
        }
    
        public void setRoleName(String roleName) {
            this.roleName = roleName;
        }
    
        public User getUser() {
            return user;
        }
    
        public void setUser(User user) {
            this.user = user;
        }
    
        public List<Permission> getPermissions() {
            return permissions;
        }
    
        public void setPermissions(List<Permission> permissions) {
            this.permissions = permissions;
        }
    }

      (3)权限:Permission.class

    @Entity
    public class Permission {
    
        @Id
        @GeneratedValue(strategy = GenerationType.AUTO)
        private Long id;
        private String permission;
        @ManyToOne(fetch = FetchType.EAGER)
        private Role role;
    
        public Long getId() {
            return id;
        }
    
        public void setId(Long id) {
            this.id = id;
        }
    
        public String getPermission() {
            return permission;
        }
    
        public void setPermission(String permission) {
            this.permission = permission;
        }
    
        public Role getRole() {
            return role;
        }
    
        public void setRole(Role role) {
            this.role = role;
        }
    }

       5)然后就是配置对应的验证,以及过滤条件

      (1)验证,以及权限的添加MyShiroRealm.class

    //实现AuthorizingRealm接口用户用户认证
    public class MyShiroRealm extends AuthorizingRealm{
    
        //用于用户查询
        @Autowired
        private ILoginService loginService;
    
        //角色权限和对应权限添加
        @Override
        protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
            //获取登录用户名
            String name= (String) principalCollection.getPrimaryPrincipal();
            //查询用户名称
            User user = loginService.findByName(name);
            //添加角色和权限
            SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
            for (Role role:user.getRoles()) {
                //添加角色
                simpleAuthorizationInfo.addRole(role.getRoleName());
                for (Permission permission:role.getPermissions()) {
                    //添加权限
                    simpleAuthorizationInfo.addStringPermission(permission.getPermission());
                }
            }
            return simpleAuthorizationInfo;
        }
    
        //用户认证
        @Override
        protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
            //加这一步的目的是在Post请求的时候会先进认证,然后在到请求
            if (authenticationToken.getPrincipal() == null) {
                return null;
            }
            //获取用户信息
            String name = authenticationToken.getPrincipal().toString();
            User user = loginService.findByName(name);
            if (user == null) {
                //这里返回后会报出对应异常
                return null;
            } else {
                //这里验证authenticationToken和simpleAuthenticationInfo的信息
                SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(name, user.getPassword().toString(), getName());
                return simpleAuthenticationInfo;
            }
        }
    }

      (2)过滤配置:ShiroConfiguration.class

    @Configuration
    public class ShiroConfiguration {
    
        //将自己的验证方式加入容器
        @Bean
        public MyShiroRealm myShiroRealm() {
            MyShiroRealm myShiroRealm = new MyShiroRealm();
            return myShiroRealm;
        }
    
        //权限管理,配置主要是Realm的管理认证
        @Bean
        public SecurityManager securityManager() {
            DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
            securityManager.setRealm(myShiroRealm());
            return securityManager;
        }
    
        //Filter工厂,设置对应的过滤条件和跳转条件
        @Bean
        public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) {
            ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
            shiroFilterFactoryBean.setSecurityManager(securityManager);
            Map<String,String> map = new HashMap<String, String>();
            //登出
            map.put("/logout","logout");
            //对所有用户认证
            map.put("/**","authc");
            //登录
            shiroFilterFactoryBean.setLoginUrl("/login");
            //首页
            shiroFilterFactoryBean.setSuccessUrl("/index");
            //错误页面,认证不通过跳转
            shiroFilterFactoryBean.setUnauthorizedUrl("/error");
            shiroFilterFactoryBean.setFilterChainDefinitionMap(map);
            return shiroFilterFactoryBean;
        }
    
        //加入注解的使用,不加入这个注解不生效
        @Bean
        public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
            AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
            authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
            return authorizationAttributeSourceAdvisor;
        }
    }

      6)接下来就是数据访问层、业务层、以及控制层

      (1)数据层:BaseRepository.class,UserRepository.class,RoleRepository.class

    @NoRepositoryBean
    public interface BaseRepository<T,I extends Serializable> extends PagingAndSortingRepository<T,I>,JpaSpecificationExecutor<T>{
    
    }
    public interface UserRepository extends BaseRepository<User,Long>{
        User findByName(String name);
    }
    public interface RoleRepository extends BaseRepository<Role,Long> {
    
    }

      (2)业务层:LoginServiceImpl.class

    @Service
    @Transactional
    public class LoginServiceImpl implements ILoginService {
    
        @Autowired
        private UserRepository userRepository;
        @Autowired
        private RoleRepository roleRepository;
    
        //添加用户
        @Override
        public User addUser(Map<String, Object> map) {
            User user = new User();
            user.setName(map.get("username").toString());
            user.setPassword(Integer.valueOf(map.get("password").toString()));
            userRepository.save(user);
            return user;
        }
    
        //添加角色
        @Override
        public Role addRole(Map<String, Object> map) {
            User user = userRepository.findOne(Long.valueOf(map.get("userId").toString()));
            Role role = new Role();
            role.setRoleName(map.get("roleName").toString());
            role.setUser(user);
            Permission permission1 = new Permission();
            permission1.setPermission("create");
            permission1.setRole(role);
            Permission permission2 = new Permission();
            permission2.setPermission("update");
            permission2.setRole(role);
            List<Permission> permissions = new ArrayList<Permission>();
            permissions.add(permission1);
            permissions.add(permission2);
            role.setPermissions(permissions);
            roleRepository.save(role);
            return role;
        }
    
        //查询用户通过用户名
        @Override
        public User findByName(String name) {
            return userRepository.findByName(name);
        }
    }

      (3)控制层:LoginResource.class

    @RestController
    public class LoginResource {
    
        @Autowired
        private ILoginService loginService;
    
        //退出的时候是get请求,主要是用于退出
        @RequestMapping(value = "/login",method = RequestMethod.GET)
        public String login(){
            return "login";
        }
    
        //post登录
        @RequestMapping(value = "/login",method = RequestMethod.POST)
        public String login(@RequestBody Map map){
            //添加用户认证信息
            Subject subject = SecurityUtils.getSubject();
            UsernamePasswordToken usernamePasswordToken = new UsernamePasswordToken(
                    map.get("username").toString(),
                    map.get("password").toString());
            //进行验证,这里可以捕获异常,然后返回对应信息
            subject.login(usernamePasswordToken);
            return "login";
        }
    
        @RequestMapping(value = "/index")
        public String index(){
            return "index";
        }
    
        //登出
        @RequestMapping(value = "/logout")
        public String logout(){
            return "logout";
        }
    
        //错误页面展示
        @RequestMapping(value = "/error",method = RequestMethod.POST)
        public String error(){
            return "error ok!";
        }
    
        //数据初始化
        @RequestMapping(value = "/addUser")
        public String addUser(@RequestBody Map<String,Object> map){
            User user = loginService.addUser(map);
            return "addUser is ok! 
    " + user;
        }
    
        //角色初始化
        @RequestMapping(value = "/addRole")
        public String addRole(@RequestBody Map<String,Object> map){
            Role role = loginService.addRole(map);
            return "addRole is ok! 
    " + role;
        }
    
        //注解的使用
        @RequiresRoles("admin")
        @RequiresPermissions("create")
        @RequestMapping(value = "/create")
        public String create(){
            return "Create success!";
        }
    }

      注:这里对于注解的使用,在最后一个很重要!

     7)shiro的使用基本上就是这样子了,主要是权限的控制,其他的主要是做跳转和切换使用

     8)最后配上数据库信息:结合控制层观看

    user:

    role:

    permission:
