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;
    }
}
