标签 spring boot 1.5.4 集成 shiro+cas shiro cas 实现单点登陆权限控制栏目 Spring 繁體版

原文原文链接

1.安装cas-server-3.5.2css

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

下载地址：cas-server-3.5.2-release.zipjava

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

注意：github

输入 <tomcat_key> 的密钥口令

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

2.配置ehcache缓存web

<?xml version="1.0" encoding="UTF-8"?>
<ehcache updateCheck="false" name="shiroCache">

    <defaultCache
            maxElementsInMemory="10000"
            eternal="false"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            overflowToDisk="false"
            diskPersistent="false"
            diskExpiryThreadIntervalSeconds="120"
    />
</ehcache>

3.添加maven依赖spring

        <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注解数据库

@ServletComponentScan
@SpringBootApplication
public class Application {

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

5.配置shiro+casapache

package com.hdwang.config.shiroCas;

import org.apache.shiro.cas.CasFilter;
