七、spring boot 1.5.4 集成shiro+cas，实现单点登录和权限控制

1.安装cas-server-3.5.2

官网：https://github.com/apereo/cas/releases/tag/v3.5.2

下载地址：cas-server-3.5.2-release.zip

安装参考文章：http://blog.csdn.net/xuxuchuan/article/details/54924933

注意：

输入 <tomcat_key> 的密钥口令

(如果和密钥库口令相同, 按回车) ,这里直接回车，也采用keystore密码changeit，否则tomcat启动报错！

2.配置ehcache缓存

<?xml version="1.0" encoding="UTF-8"?>
<ehcache updateCheck="false" name="shiroCache"><defaultCachemaxElementsInMemory="10000"eternal="false"timeToIdleSeconds="120"timeToLiveSeconds="120"overflowToDisk="false"diskPersistent="false"diskExpiryThreadIntervalSeconds="120"/>
</ehcache>

3.添加maven依赖

        <dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-spring</artifactId><version>1.2.4</version></dependency><dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-ehcache</artifactId><version>1.2.4</version></dependency><dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-cas</artifactId><version>1.2.4</version></dependency>

4.启动类添加@ServletComponentScan注解

@ServletComponentScan
@SpringBootApplication
public class Application {
public static void main(String[] args){SpringApplication.run(Application.class,args);}
}

5.配置shiro+cas
