CAS (10) —— JBoss EAP 6.4下部署CAS时出现错误exception.message=Error decoding flow execution的解决办法
jboss版本: jboss-eap-6.4-CVE-2015-7501
jdk版本: 1.7.0_79
cas版本: cas 4.1.3
参考来源:
Nabble: exception.message=Error+decoding+flow+execution
CAS 4.1.1 - JDBC authentication, failed to deploy

问题描述
在CAS部署到jboss后台启动时会出现下面错误1，如果忽略此问题，在登录成功并且尝试重定会应用的页面时，会在重定向url后面加上&exception.message=Error+decoding+flow+execution字样，下面所描述的错误2。
1. Slf4jLogger

2. exception.message=
解决方案
在应用中去掉jboss容器自带的slf4j的依赖
1. 在路径<your_cas_server_webapp>/../webapp/WEB-INF/下
新建文件"jboss-deployment-structure.xml"
2. 文件配置如下
<jboss-deployment-structure>
<deployment>
<exclusions>
<module name="org.slf4j" />
<module name="org.slf4j.impl" />
<module name="org.slf4j.jcl-over-slf4j" />
<module name="org.slf4j.ext" />
</exclusions>
</deployment>
</jboss-deployment-structure>
3. 重新发布
扩展
依照以上方法就可以解决本文主要关注的两个问题，但是这种方案会使我们引入一个新的问题。在jboss启动的时候服务器仍然会报slf4j的错误SLF4J: Class path contains multiple SLF4J bindings.
14:09:52,144 ERROR [stderr] (ServerService Thread Pool -- 158)

尝试解决此问题
首先我们在<your_cas_server_webapp>的根目录下，从命令行运行，查看依赖树
/cas-server-webapp$mvn dependency:tree

经查看发现org.slf4j.impl.StaticLoggerBinder被打入了cas-server-core中，暂时不知道cas的核心开发何故为此，由于cas-server-core是核心jar，我们是否能够直接移除org.apache.logging.log4j:log4j-slf4j-impl:jar:2.3:runtime这个依赖？

如果去掉org.apache.logging.log4j:log4j-slf4j-impl:jar:2.3:runtime这个依赖在部署时会出错，可是目前的实现方式是显示的在slf4j中override掉原来的实现，实例化CAS自己的LogFactory
// Line:
private StaticLoggerBinder() {
this.loggerFactory = new CasLoggerFactory();
}
此问题待解
目前状态
网上很多文章介绍关于jaxb和jersey在jboss下使用方法，但是此处的警告消息warn并不会消除，这是当前6.4版本的一个bug，请参考JBEAP-69
