shiro springboot 會話管理

一概要

Shiro提供了完整的企業(yè)級會話管理功能，不依賴于底層容器（如Tomcat）赋续，不管是J2SE還是J2EE環(huán)境都可以使用干奢，提供了會話管理，會話事件監(jiān)聽糯彬，會話存儲/持久化凭语，容器無關(guān)的集群，失效/過期支持撩扒，對Web的透明支持似扔，SSO單點登錄的支持等特性吨些。即直接使用 Shiro 的會話管理可以直接替換如 Web 容器的會話管理。

shiro-redis開源項目已經(jīng)很好的將shiro與redis整合到一起炒辉，實現(xiàn)了將session存入redis豪墅，可以方便的用于session共享實現(xiàn)集群部署。

主要涉及到緩存跟session的配置

二使用步驟

導(dǎo)入依賴

配置Reids緩存管理器

將緩存信息保存到Redis中

<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="java" cid="n15" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Monaco, Consolas, "Andale Mono", "DejaVu Sans Mono", monospace; margin-top: 0px; margin-bottom: 20px; font-size: 0.9rem; display: block; break-inside: avoid; text-align: left; white-space: normal; background: rgb(51, 51, 51); position: relative !important; padding: 10px 10px 10px 30px; width: inherit; color: rgb(184, 191, 198); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">@Bean
public RedisCacheManager cacheManager(){
RedisCacheManager redisCacheManager = new RedisCacheManager();
redisCacheManager.setRedisManager(redisManager());
//redis中針對不同用戶緩存
redisCacheManager.setPrincipalIdFieldName("username");
//用戶權(quán)限信息緩存時間
redisCacheManager.setExpire(200000);
return redisCacheManager;
}</pre>

配置RedisSessionDAO

SessionDAO的作用是為Session提供CRUD并進行持久化的一個shiro組件

<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="java" cid="n19" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Monaco, Consolas, "Andale Mono", "DejaVu Sans Mono", monospace; margin-top: 0px; margin-bottom: 20px; font-size: 0.9rem; display: block; break-inside: avoid; text-align: left; white-space: normal; background: rgb(51, 51, 51); position: relative !important; padding: 10px 10px 10px 30px; width: inherit; color: rgb(184, 191, 198); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">@Bean
