springboot整合shiro(新手教程)

咱们也就不多哔哔，直接开始
我先放我自己写的项目结构

第一步: 想啥了，肯定是先创建一个springboot的项目

第二步:配置pom文件

<dependency>
			<groupId>org.apache.shiro</groupId>
			<artifactId>shiro-spring</artifactId>
			<version>1.4.0</version>
</dependency>

<!-- 注解工具，更加方便的使用log -->
<dependency>
			<groupId>org.projectlombok</groupId>
			<artifactId>lombok</artifactId>
			<optional>true</optional>
</dependency>

第三步:登录控制器

这是登录ajax跳的方法,就照着图片上敲就行了

第四步：创建用户认证授权方法类

public class CustomRealm extends AuthorizingRealm {

    @Autowired
    private LoginService loginService;

    @Override  //这边是权限认证
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        String name = (String) principals.getPrimaryPrincipal();
        UserInfo userInfo = new UserInfo(0,name,"","",null);
        UserInfo user = loginService.getUserByName(userInfo);

        //添加角色和权限
        SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();

        for (Role role : user.getRoles()) {

            //添加角色
            simpleAuthorizationInfo.addRole(role.getRoleName());

            //添加权限
            for (Permissions permissions : role.getPermissions()) {
                simpleAuthorizationInfo.addStringPermission(permissions.getPermissionsName());
            }

        }
        return simpleAuthorizationInfo;
    }

    @Override   //这里是登录认证
    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();

        UserInfo userInfo = new UserInfo(0,name,"","",null);
        UserInfo user = loginService.getUserByName(userInfo);

        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.getUserpwd().toString(), getName());
            return simpleAuthenticationInfo;
        }
    }
}

第五步：shiro配置类

@Configuration
public class ShiroConfig {

    @Bean
    @ConditionalOnMissingBean
    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator defaultAAP = new DefaultAdvisorAutoProxyCreator();
        defaultAAP.setProxyTargetClass(true);
        return defaultAAP;
    }

    //将自己的验证方式加入容器
    @Bean
    public CustomRealm myShiroRealm() {
        CustomRealm customRealm = new CustomRealm();
        return customRealm;
    }

    //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<>();

        //登出
        //map.put("/logout", "logout");

        /**
         * anon 匿名用户可以访问
         * user:认证用户可访问
         * perms:对应权限可访问
         * role:对应角色可访问
         */

        /**
         * 配置statics下面静态文件可以访问
         */
        map.put("/statics/**", "anon");

        map.put("/login", "anon");

        /**
         * 对所有请求认证，这一步必须放在后面，不然会有问题
         */
        map.put("/**", "authc");

        //登录
        shiroFilterFactoryBean.setLoginUrl("/");

        //登录成功之后，允许跳首页的控制器方法
        shiroFilterFactoryBean.setSuccessUrl("/index");

        //错误页面，认证不通过跳转
        //shiroFilterFactoryBean.setUnauthorizedUrl("/error");

        //添加配置
        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;
    }
}

第六步：异常类

@ControllerAdvice
@Slf4j
public class MyExceptionHandler {
    @ExceptionHandler
    public String ErrorHandler(AuthorizationException e) {
        log.error("没有通过权限验证！", e);
        return "my_error";
    }
}

按着我的一步一步的照着敲就可以了，我也是第一次学习shiro，所以写的比较糟糕
所以我这边放出我学习的链接，这里面作者讲的很详细，而且还有附带demo
