Spring Boot + Vue + Shiro 实现前后端分离，写得太好了！ (qq.com)
1.OPTIONS请求不带'Authorization'请求头字段：
前后端分离项目中，由于跨域，会导致复杂请求，即会发送preflighted request，这样会导致在GET／POST等请求之前会先发一个OPTIONS请求，但OPTIONS请求并不带shiro的'Authorization'字段（shiro的Session），即OPTIONS请求不能通过shiro验证，会返回未认证的信息。
解决方法：给shiro增加一个过滤器，过滤OPTIONS请求
public class CORSAuthenticationFilter extends FormAuthenticationFilter {
private static final Logger logger = LoggerFactory.getLogger(CORSAuthenticationFilter.class);
public CORSAuthenticationFilter() {
super();
}
@Override
public boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) {
//Always return true if the request's method is OPTIONSif (request instanceof HttpServletRequest) {
if (((HttpServletRequest) request).getMethod().toUpperCase().equals("OPTIONS")) {
return true;
}
}
return super.isAccessAllowed(request, response, mappedValue);
}
@Override
protected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws Exception {
HttpServletResponse res = (HttpServletResponse)response;
res.setHeader("Access-Control-Allow-Origin", "*");
res.setStatus(HttpServletResponse.SC_OK);
res.setCharacterEncoding("UTF-8");
PrintWriter writer = res.getWriter();
Map<String, Object> map= new HashMap<>();
map.put("code", 702);
map.put("msg", "未登录");
writer.write(JSON.toJSONString(map));
writer.close();
return false;
}
}
贴一下我的config文件：
@Configuration
public class ShiroConfig {
@Bean
public Realm realm() {
return new DDRealm();
}
@Bean
public CacheManager cacheManager() {
return new MemoryConstrainedCacheManager();
}
/**
* cookie对象;
* rememberMeCookie()方法是设置Cookie的生成模版，比如cookie的name，cookie的有效时间等等。
* @return
*/
@Bean
public SimpleCookie rememberMeCookie(){
//System.out.println("ShiroConfiguration.rememberMeCookie()");
//这个参数是cookie的名称，对应前端的checkbox的name = rememberMe
SimpleCookie simpleCookie = new SimpleCookie("rememberMe");
//<!-- 记住我cookie生效时间30天 ,单位秒;-->
simpleCookie.setMaxAge(259200);
return simpleCookie;
}
/**
* cookie管理对象;
* rememberMeManager()方法是生成rememberMe管理器，而且要将这个rememberMe管理器设置到securityManager中
* @return
*/
@Bean
public CookieRememberMeManager rememberMeManager(){
//System.out.println("ShiroConfiguration.rememberMeManager()");
CookieRememberMeManager cookieRememberMeManager = new CookieRememberMeManager();
cookieRememberMeManager.setCookie(rememberMeCookie());
//rememberMe cookie加密的密钥 建议每个项目都不一样 默认AES算法 密钥长度(128 256 512 位)
cookieRememberMeManager.setCipherKey(Base64.decode("2AvVhdsgUs0FSA3SDFAdag=="));
return cookieRememberMeManager;
}
@Bean
public SecurityManager securityManager() {
DefaultWebSecurityManager sm = new DefaultWebSecurityManager();
sm.setRealm(realm());
sm.setCacheManager(cacheManager());
//注入记住我管理器
sm.setRememberMeManager(rememberMeManager());
//注入自定义sessionManager
sm.setSessionManager(sessionManager());
return sm;
}
//自定义sessionManager
@Bean
public SessionManager sessionManager() {
return new CustomSessionManager();
}
public CORSAuthenticationFilter corsAuthenticationFilter(){
return new CORSAuthenticationFilter();
}
@Bean(name = "shiroFilter")
public ShiroFilterFactoryBean getShiroFilterFactoryBean(SecurityManager securityManager) {
ShiroFilterFactoryBean shiroFilter = new ShiroFilterFactoryBean();
shiroFilter.setSecurityManager(securityManager);
//SecurityUtils.setSecurityManager(securityManager);
Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
//配置不会被拦截的链接，顺序判断
filterChainDefinitionMap.put("/", "anon");
filterChainDefinitionMap.put("/static/js/**", "anon");
filterChainDefinitionMap.put("/static/css/**", "anon");
filterChainDefinitionMap.put("/static/fonts/**", "anon");
filterChainDefinitionMap.put("/login/**", "anon");
filterChainDefinitionMap.put("/corp/call_back/receive", "anon");
//authc:所有url必须通过认证才能访问，anon:所有url都可以匿名访问
filterChainDefinitionMap.put("/**", "corsAuthenticationFilter");
shiroFilter.setFilterChainDefinitionMap(filterChainDefinitionMap);
//自定义过滤器
Map<String, Filter> filterMap = new LinkedHashMap<>();
filterMap.put("corsAuthenticationFilter", corsAuthenticationFilter());
shiroFilter.setFilters(filterMap);
return shiroFilter;
}
/**
* Shiro生命周期处理器 * @return
*/
@Bean
public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
return new LifecycleBeanPostProcessor();
}
/**
* 开启Shiro的注解(如@RequiresRoles,@RequiresPermissions),需借助SpringAOP扫描使用Shiro注解的类,并在必要时进行安全逻辑验证 * 配置以下两个bean(DefaultAdvisorAutoProxyCreator(可选)和AuthorizationAttributeSourceAdvisor)即可实现此功能 * @return
*/
@Bean
@DependsOn({"lifecycleBeanPostProcessor"})
public DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator() {
DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
advisorAutoProxyCreator.setProxyTargetClass(true);
return advisorAutoProxyCreator;
}
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
return authorizationAttributeSourceAdvisor;
}
}
2.设置session失效时间
shiro session默认失效时间是30min，我们在自定义的sessionManager的构造函数中设置失效时间为其他值
public class CustomSessionManager extends DefaultWebSessionManager {
private static final Logger logger = LoggerFactory.getLogger(CustomSessionManager.class);
private static final String AUTHORIZATION = "Authorization";
private static final String REFERENCED_SESSION_ID_SOURCE = "Stateless request";
public CustomSessionManager() {
super();
setGlobalSessionTimeout(DEFAULT_GLOBAL_SESSION_TIMEOUT * 48);
}
@Override
protected Serializable getSessionId(ServletRequest request, ServletResponse response) {
String sessionId = WebUtils.toHttp(request).getHeader(AUTHORIZATION);//如果请求头中有 Authorization 则其值为sessionId
if (!StringUtils.isEmpty(sessionId)) {
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE, REFERENCED_SESSION_ID_SOURCE);
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, sessionId);
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID, Boolean.TRUE);
return sessionId;
} else {
//否则按默认规则从cookie取sessionId
return super.getSessionId(request, response);
}
}
}
五、部署项目
前端项目部署主要分两种方法：
1.将前端项目打包（npm run build）成静态资源文件，放入后端，一起打包。后端写一个Controller返回前端界面（我使用Vue开发的是单页面应用），但是这样其实又将前后端耦合在一起了，不过起码做到前后端分离开发，方便开发的目的已经达成，也初步达成了要求，由于项目的需要，我是这样做的，并且免去了跨域问题。
@RequestMapping(value = {"/", "/index"}, method = RequestMethod.GET)
public String index() {
return "/index";
}
2.将前端工程另启一个服务（tomcat，nginx，nodejs），这样有跨域的问题。
说一下我遇到的问题：
nginx反向代理，导致当访问无权限的页面时，shiro 302到unauth的controller，访问的地址是https，重定向地址是http，导致了无法访问。
不使用shiro的 shiroFilter.setLoginUrl("/unauth");
当页面无权限访问时，我们在过滤器里直接返回错误信息，不利用shiro自带的跳转。看过滤器中的onAccessDenied函数
public class CORSAuthenticationFilter extends FormAuthenticationFilter {
private static final Logger logger = LoggerFactory.getLogger(CORSAuthenticationFilter.class);
public CORSAuthenticationFilter() {
super();
}
@Override
public boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) {
//Always return true if the request's method is OPTIONS
if (request instanceof HttpServletRequest) {
if (((HttpServletRequest) request).getMethod().toUpperCase().equals("OPTIONS")) {
return true;
}
}
return super.isAccessAllowed(request, response, mappedValue);
}
@Override
protected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws Exception {
HttpServletResponse res = (HttpServletResponse)response;
res.setHeader("Access-Control-Allow-Origin", "*");
res.setStatus(HttpServletResponse.SC_OK);
res.setCharacterEncoding("UTF-8");
PrintWriter writer = res.getWriter();
Map<String, Object> map= new HashMap<>();
map.put("code", 702);
map.put("msg", "未登录");
writer.write(JSON.toJSONString(map));
writer.close();
return false;
}
}
