Shiro
Shiro 主要分为 安全认证 和 接口授权 两个部分，其中的核心组件为 Subject、 SecurityManager、 Realms，公共部分 Shiro 都已经为我们封装好了，我们只需要按照一定的规则去编写响应的代码即可…
Subject 表示主体，将用户的概念理解为当前操作的主体，它即可以是一个通过浏览器请求的用户，也可能是一个运行的程序，外部应用与 Subject 进行交互，记录当前操作用户。Subject 代表当前用户的安全操作，SecurityManager 则管理所有用户的安全操作。
SecurityManager 即安全管理器，对所有的 Subject 进行安全管理，并通过它来提供安全管理的各种服务（认证、授权等）
Realm 充当了应用与数据安全间的 桥梁 或 连接器。当对用户执行认证（登录）和授权（访问控制）验证时，Shiro 会从应用配置的 Realm 中查找用户及其权限信息。
1.导入shiro依赖
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.4.0</version>
</dependency>
<!-- hiro-redis插件用于实现:将用户信息交给redis管理 -->
<dependency>
<groupId>org.crazycake</groupId>
<artifactId>shiro-redis</artifactId>
<version>2.8.24</version>
</dependency>
2.shiro配置类

filterChainDefinitionMap.put("/static/**", "anon");
filterChainDefinitionMap.put("/*.html", "anon");
filterChainDefinitionMap.put("/ajaxLogin", "anon");
filterChainDefinitionMap.put("/login", "anon");
filterChainDefinitionMap.put("/**", "authc");
// 配置shiro默认登录界面地址，前后端分离中登录界面跳转应由前端路由控制，后台仅返回json数据
shiroFilterFactoryBean.setLoginUrl("/unauth");
// 登录成功后要跳转的链接
// shiroFilterFactoryBean.setSuccessUrl("/index");

shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
return shiroFilterFactoryBean;

3.安全认证和权限验证的核心，自定义Realm
import com.google.gson.JsonObject;
import com.test.cbd.service.UserService;
import com.test.cbd.vo.SysPermission;
import com.test.cbd.vo.SysRole;
import com.test.cbd.vo.UserInfo;
import org.apache.commons.beanutils.BeanUtils;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.util.ByteSource;
import springfox.documentation.spring.web.json.Json;
import javax.annotation.Resource;
import java.util.HashSet;
import java.util.Set;
public class MyShiroRealm extends AuthorizingRealm {
@Resource
private UserService userInfoService;
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals){
// // 权限信息对象info,用来存放查出的用户的所有的角色（role）及权限（permission）
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
Session session = SecurityUtils.getSubject().getSession();
UserInfo user = (UserInfo) session.getAttribute("USER_SESSION");
// 用户的角色集合
Set<String> roles = new HashSet<>();
roles.add(user.getRoleList().get(0).getRole());
authorizationInfo.setRoles(roles);
return authorizationInfo;
}
/*主要是用来进行身份认证的，也就是说验证用户输入的账号和密码是否正确。*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token)
throws AuthenticationException {
// System.out.println("MyShiroRealm.doGetAuthenticationInfo()");
// 获取用户的输入的账号.
String username = (String) token.getPrincipal();
// System.out.println(token.getCredentials());
// 通过username从数据库中查找 User对象，如果找到，没找到.
// 实际项目中，这里可以根据实际情况做缓存，如果不做，Shiro自己也是有时间间隔机制，2分钟内不会重复执行该方法
UserInfo userInfo = userInfoService.findByUsername(username);
// Subject subject = SecurityUtils.getSubject();
// Session session = subject.getSession();
// session.setAttribute("role",userInfo.getRoleList());
// System.out.println("----->>userInfo="+userInfo);
if (userInfo == null) {
return null;
}
if (userInfo.getState() == 1) { //账户冻结
throw new LockedAccountException();
}
String credentials = userInfo.getPassword();
System.out.println("credentials="+credentials);
ByteSource credentialsSalt = ByteSource.Util.bytes(username);
SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
userInfo.getUserName(), //用户名
credentials, //密码
credentialsSalt,
getName() //realm name
);
Session session = SecurityUtils.getSubject().getSession();
session.setAttribute("USER_SESSION", userInfo);
return authenticationInfo;
}
}
4.全局异常处理器
import com.alibaba.fastjson.support.spring.FastJsonJsonView;
import org.apache.shiro.authz.UnauthenticatedException;
import org.apache.shiro.authz.UnauthorizedException;
import org.springframework.web.servlet.HandlerExceptionResolver;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.HashMap;
import java.util.Map;
/**
* Created by Administrator on 2017/12/11.
* 全局异常处理
*/
public class MyExceptionHandler implements HandlerExceptionResolver {
public ModelAndView resolveException(HttpServletRequest httpServletRequest,
HttpServletResponse httpServletResponse, Object o, Exception ex) {
ModelAndView mv = new ModelAndView();
FastJsonJsonView view = new FastJsonJsonView();
Map<String, Object> attributes = new HashMap<String, Object>();
if (ex instanceof UnauthenticatedException) {
attributes.put("code", "1000001");
attributes.put("msg", "token错误");
} else if (ex instanceof UnauthorizedException) {
attributes.put("code", "1000002");
attributes.put("msg", "用户无权限");
} else {
attributes.put("code", "1000003");
attributes.put("msg", ex.getMessage());
}
view.setAttributesMap(attributes);
mv.setView(view);
return mv;
}
}
5.因为现在的项目大多都是前后端分离的，所以我们需要实现自己的session管理
import org.apache.shiro.web.servlet.ShiroHttpServletRequest;
import org.apache.shiro.web.session.mgt.DefaultWebSessionManager;
import org.apache.shiro.web.util.WebUtils;
import org.springframework.util.StringUtils;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import java.io.Serializable;
public class MySessionManager extends DefaultWebSessionManager {
private static final String TOKEN = "token";
private static final String REFERENCED_SESSION_ID_SOURCE = "Stateless request";
public MySessionManager() {
super();
}
@Override
protected Serializable getSessionId(ServletRequest request, ServletResponse response) {
String id = WebUtils.toHttp(request).getHeader(TOKEN);
//如果请求头中有 token 则其值为sessionId
if (!StringUtils.isEmpty(id)) {
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE, REFERENCED_SESSION_ID_SOURCE);
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, id);
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID, Boolean.TRUE);
return id;
} else {
//否则按默认规则从cookie取sessionId
return super.getSessionId(request, response);
}
}
}
6.控制器
import com.alibaba.fastjson.JSONObject;
import com.test.cbd.vo.UserInfo;
import io.swagger.annotations.Api;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.IncorrectCredentialsException;
import org.apache.shiro.authc.LockedAccountException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authz.annotation.RequiresRoles;
import org.apache.shiro.crypto.hash.SimpleHash;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.util.ByteSource;
import org.springframework.web.bind.annotation.*;
import javax.servlet.http.HttpServletRequest;
import java.net.InetAddress;
@Slf4j
@Api(value="shiro测试",description="shiro测试")
@RestController
@RequestMapping("/")
public class ShiroLoginController {
/**
* 登录测试
* @param userInfo
* @return
*/
@RequestMapping(value = "/ajaxLogin", method = RequestMethod.POST)
@ResponseBody
public String ajaxLogin(UserInfo userInfo) {
JSONObject jsonObject = new JSONObject();
UsernamePasswordToken token = new UsernamePasswordToken(userInfo.getUserName(), userInfo.getPassword());
Subject subject = SecurityUtils.getSubject();
try {
subject.login(token);
jsonObject.put("token", subject.getSession().getId());
jsonObject.put("msg", "登录成功");
} catch (IncorrectCredentialsException e) {
jsonObject.put("msg", "密码错误");
} catch (LockedAccountException e) {
jsonObject.put("msg", "登录失败，该用户已被冻结");
} catch (AuthenticationException e) {
jsonObject.put("msg", "该用户不存在");
} catch (Exception e) {
e.printStackTrace();
}
return jsonObject.toString();
}
/**
* 鉴权测试
* @param userInfo
* @return
*/
@RequestMapping(value = "/check", method = RequestMethod.GET)
@ResponseBody
@RequiresRoles("guest")
public String check() {
JSONObject jsonObject = new JSONObject();
jsonObject.put("msg", "鉴权测试");
return jsonObject.toString();
}
}
常用注解
@RequiresGuest 代表无需认证即可访问，同理的就是 /path=anon
@RequiresAuthentication 需要认证，只要登录成功后就允许你操作
@RequiresPermissions 需要特定的权限，没有则抛出 AuthorizationException
@RequiresRoles 需要特定的橘色，没有则抛出 AuthorizationException
7.以上就是shiro登陆和鉴权的主要配置和类，下面补充一下其他信息。
①application.properties中shiro-redis相关配置：
spring.redis.shiro.host=127.0.0.1 spring.redis.shiro.port=6379 spring.redis.shiro.timeout=5000 spring.redis.shiro.password=123456
②因为数据是模拟的，所以在登陆认证的时候，并没有通过数据库查用户信息，可以通过以下方式模拟加密后的密码：
/**
* 生成测试用的md5加密的密码
* @param args
*/
public static void main(String[] args) {
String hashAlgorithmName = "md5";
String credentials = "123456";//密码
int hashIterations = 1024;
ByteSource credentialsSalt = ByteSource.Util.bytes("root");//账号
String obj = new SimpleHash(hashAlgorithmName, credentials, credentialsSalt, hashIterations).toHex();
System.out.println(obj);
}
上面obj的结果是b1ba853525d0f30afe59d2d005aad96c
③登陆认证的findByUsername方法，模拟到数据库查询用户信息，实际是自己构造的数据，偷偷懒。
public UserInfo findByUsername(String userName){
SysRole admin = SysRole.builder().role("admin").build();
List<SysPermission> list=new ArrayList<SysPermission>();
SysPermission sysPermission=new SysPermission("read");
SysPermission sysPermission1=new SysPermission("write");
list.add(sysPermission);
list.add(sysPermission1);
admin.setPermissions(list);
UserInfo root = UserInfo.builder().userName("root").password("b1ba853525d0f30afe59d2d005aad96c").credentialsSalt("123").state(0).build();
List<SysRole> roleList=new ArrayList<SysRole>();
roleList.add(admin);
root.setRoleList(roleList);
return root;
}
8.结果演示
输入正确的账号密码时，返回信息如下：
故意输错密码时，返回信息如下：
鉴权时，如果该用户没有角色：
