之前项目鉴权一直使用的Shiro，那是在Spring MVC里面使用的比较多，而且都是用XML来配置，用Shiro来做权限控制相对比较简单而且成熟，而且我一直都把Shiro的session放在mongodb中，这个比较符合mongodb的设计初衷，而且在分布式项目中mongodb也作为一个中间层，用来很好很方便解决分布式环境下的session同步的问题。
自从SpringBoot问世之后我的项目基本上能用SpringBoot的就会用SpringBoot，用MAVEN做统一集中管理也很方便，虽然SpringBoot也提供了一套权限安全框架Spring Security，但是相对来说还是不是太好用，所以还是用Shiro来的方便一点，SpringBoot集成Shiro要比Spring MVC要简单的多，至少没有一堆XML配置，看起来更清爽，那么接下来我们就开始集成。
第一步必然是在MAVEN中先添加Shiro和mongo的依赖，我用的Shiro版本是
<shiro.version>1.2.3</shiro.version>
添加依赖：
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>${shiro.version}</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-web</artifactId>
<version>${shiro.version}</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>${shiro.version}</version>
</dependency>
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>3.0.0</version>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
<version>1.7.0.RELEASE</version>
</dependency>
然后在application.xml或yml中配置mongodb
spring.data.mongodb.host=127.0.0.1
spring.data.mongodb.port=27017
spring.data.mongodb.database=SHIRO_INFO
配置完成之后我们开始正式写Shiro认证的代码，先自定义一个鉴权realm，继承自AuthorizingRealm
public class ShiroDbRealm extends AuthorizingRealm {
/**
* 用户信息操作
*/
private SystemUserService systemUserService;
public ShiroDbRealm() {}
public ShiroDbRealm(SystemUserService systemUserService) {
this.systemUserService = systemUserService;
}
/**
* 授权信息
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
SimpleAuthorizationInfo info = (SimpleAuthorizationInfo) ShiroKit.getShiroSessionAttr("perms");
if (null != info && !CollectionUtils.isEmpty(info.getRoles())
&& !CollectionUtils.isEmpty(info.getStringPermissions())) {
return info;
}
return null;
}
/**
* 认证信息
*/
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authcToken)
throws AuthenticationException {
UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
String userName = token.getUsername();
if (userName != null && !"".equals(userName)) {
SystemUser key = new SystemUser();
key.setLoginName(token.getUsername());
key.setPassword(String.valueOf(token.getPassword()));
SystemUser user = systemUserService.login(key);
if (user != null) {
Subject userTemp = SecurityUtils.getSubject();
userTemp.getSession().setAttribute("userId", user.getId());
userTemp.getSession().setAttribute("userName", user.getUserName());
return new SimpleAuthenticationInfo(user.getLoginName(), user.getPassword(), getName());
}
}
return null;
}
}
存储session进mongodb的Repository和实现：
public interface ShiroSessionRepository {
/**
*
* @param session
*/
void saveSession(Session session);
......
}
MongoDBSessionRepository.java
public class MongoDBSessionRepository implements ShiroSessionRepository {
private MongoTemplate mongoTemplate;
public MongoDBSessionRepository() {}
public MongoDBSessionRepository(MongoTemplate mongoTemplate) {
this.mongoTemplate = mongoTemplate;
}
@Override
public void saveSession(Session session) {
if (session == null || session.getId() == null) {
return;
}
SessionBean bean = new SessionBean();
bean.setKey(getSessionKey(session.getId()));
bean.setValue(SerializeUtil.serialize(session));
bean.setPrincipal(null);
bean.setHost(session.getHost());
bean.setStartTimestamp(session.getStartTimestamp());
bean.setLastAccessTime(session.getLastAccessTime());
bean.setTimeoutTime(getTimeoutTime(session.getStartTimestamp(), session.getTimeout()));
mongoTemplate.insert(bean);
}
......
}
ShiroSessionDAO.java
public class ShiroSessionDAO extends AbstractSessionDAO {
/**
* 日志记录器
*/
private static final Logger log = LoggerFactory.getLogger(ShiroSessionDAO.class);
/**
* 数据库存储
*/
private ShiroSessionRepository shiroSessionRepository;
/**
*
* @return
*/
public ShiroSessionRepository getShiroSessionRepository() {
return shiroSessionRepository;
}
/**
*
* @param shiroSessionRepository
*/
public void setShiroSessionRepository(ShiroSessionRepository shiroSessionRepository) {
this.shiroSessionRepository = shiroSessionRepository;
}
@Override
public void update(Session session) throws UnknownSessionException {
getShiroSessionRepository().updateSession(session);
}
@Override
public void delete(Session session) {
if (session == null) {
log.error("session can not be null,delete failed");
return;
}
Serializable id = session.getId();
if (id != null) {
getShiroSessionRepository().deleteSession(id);
}
}
@Override
public Collection<Session> getActiveSessions() {
return getShiroSessionRepository().getAllSessions();
}
@Override
protected Serializable doCreate(Session session) {
Serializable sessionId = this.generateSessionId(session);
this.assignSessionId(session, sessionId);
getShiroSessionRepository().saveSession(session);
return sessionId;
}
@Override
protected Session doReadSession(Serializable sessionId) {
return getShiroSessionRepository().getSession(sessionId);
}
}
OK！所有基础类已经完成，最后写一个config用来全部初始化和配置Shiro
@Configuration
public class ShiroConfig {
@Resource
private MongoTemplate mongoTemplate;
@Resource
private SystemUserService systemUserService;// 这是用来判断用户名和密码的service
@Bean
public ShiroFilterFactoryBean shiroFilter(DefaultWebSecurityManager securityManager) {
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
shiroFilterFactoryBean.setSecurityManager(securityManager);
shiroFilterFactoryBean.setLoginUrl("/login");
shiroFilterFactoryBean.setSuccessUrl("/index");
shiroFilterFactoryBean.setUnauthorizedUrl("/403");
// 拦截器.
Map<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>();
filterChainDefinitionMap.put("/static/**", "anon");
filterChainDefinitionMap.put("/ajaxLogin", "anon");
filterChainDefinitionMap.put("/libs/**", "anon");
filterChainDefinitionMap.put("/images/**", "anon");
filterChainDefinitionMap.put("/logout", "logout");
filterChainDefinitionMap.put("/**", "authc");
shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
return shiroFilterFactoryBean;
}
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(
DefaultWebSecurityManager securityManager) {
AuthorizationAttributeSourceAdvisor adv = new AuthorizationAttributeSourceAdvisor();
adv.setSecurityManager(securityManager);
return adv;
}
@Bean
public DefaultWebSecurityManager securityManager(DefaultWebSessionManager sessionManager,
ShiroDbRealm myShiroRealm) {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
// 设置realm.
securityManager.setRealm(myShiroRealm);
securityManager.setSessionManager(sessionManager);
return securityManager;
}
/**
* 身份认证realm; (这里传递systemUserService给自定义的ShiroDbRealm初始化)
*
* @return
*/
@Bean
public ShiroDbRealm myShiroRealm() {
ShiroDbRealm myShiroRealm = new ShiroDbRealm(systemUserService);
return myShiroRealm;
}
@Bean
public DefaultWebSessionManager sessionManager(ShiroSessionDAO shiroSessionDao) {
DefaultWebSessionManager sessionManager = new DefaultWebSessionManager();
sessionManager.setGlobalSessionTimeout(1800000l);
sessionManager.setDeleteInvalidSessions(true);
sessionManager.setSessionValidationSchedulerEnabled(true);
sessionManager.setSessionDAO(shiroSessionDao);
sessionManager.setSessionIdCookieEnabled(true);
SimpleCookie cookie = new SimpleCookie(ShiroHttpSession.DEFAULT_SESSION_ID_NAME);
cookie.setHttpOnly(true);
cookie.setMaxAge(1800000);
sessionManager.setSessionIdCookie(cookie);
return sessionManager;
}
@Bean
public ShiroSessionDAO shiroSessionDao(MongoDBSessionRepository shiroSessionRepository) {
ShiroSessionDAO dao = new ShiroSessionDAO();
dao.setShiroSessionRepository(shiroSessionRepository);
return dao;
}
@Bean
MongoDBSessionRepository shiroSessionRepository() {
MongoDBSessionRepository resp = new MongoDBSessionRepository(mongoTemplate);
return resp;
}
}
好了，大功告成，这里只是一个简单的配置，代码也是我从项目里面节选和修改过的，至于在controller里面怎么使用，怎么做不同权限的鉴权工作那就在自己的代码里面实现就行。
