cas5.2.6(3)自定义登录页面
环境：jdk1.8,tomcat8
1、把tomcat下（WEB-INF/classes/services）的services复制到resource下
如果项目中没有这个文件夹，请点击maven边上的刷新按钮
2、在services下新增mytheme-10000002.json、mytheme2-10000003.json文件
mytheme-10000002.json
{
"@class": "org.apereo.cas.services.RegexRegisteredService",
"serviceId": "^(https|imaps|http)://test.*",
"name": "mytheme",
"theme": "mytheme",
"id": 10000002,
"description": "自定义主题",
"evaluationOrder": 1000
}mytheme2-10000003.json
{
"@class": "org.apereo.cas.services.RegexRegisteredService",
"serviceId": "^(https|imaps|http)://test2.*",
"name": "mytheme2",
"theme": "mytheme2",
"id": 10000003,
"description": "自定义主题2",
"evaluationOrder": 1001
}id、evaluationOrder、theme这三个属性别和其他json文件里的重名
3、修改HTTPSandIMAPS-10000001.json，使其支持http
{
"@class" : "org.apereo.cas.services.RegexRegisteredService",
"serviceId" : "^(https|imaps|http)://.*",
"name" : "HTTPS and IMAPS",
"id" : 10000001,
"description" : "This service definition authorizes all application urls that support HTTPS and IMAPS protocols.",
"evaluationOrder" : 10000
}
前面三个json文件中都新增了http
4、在application.properties里新增cas.serviceRegistry.initFromJson=true,让json配置文件生效
5、新增mytheme.properties、mytheme2.properties文件
mytheme.properties
cas.css=/themes/mytheme/css/cas.css
cas.pageTitle=\u6d4b\u8bd5\u4e00\u4e0bmytheme2.properties
cas.css=/themes/mytheme2/css/cas.css
cas.pageTitle=\u6d4b\u8bd5\u4e00\u4e0b26、在resources新建如下目录
静态资源(js,css)存放目录为src/main/resources/static/[theme_name]
html资源存(thymeleaf)放目录为src/main/resources/templates/casLoginView.html
主题配置文件存放在src/main/resources并且命名为[theme_name].properties
主题页面html存放目录为src/main/resources/templates/[theme_name]
上面四行都是网上看到的，我把json文件里的theme属性改了也能正常使用（有大佬指导详细、具体的规则请联系我！！！）
mytheme/cas.css
h1 {
color: blue;
}mytheme2/cas.css
h1 {
color: pink;
}mytheme/casLoginView.html和mytheme2/casLoginView.html一样
7、修改application.properties
在application.properties里新增cas.theme.defaultThemeName=mythem
大致意思就是使得参数service开头为http的可以进行认证，http://后面的是test1开头使用mytheme主题，test2开头使用mytheme2主题
application.properties
