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

    15:28:30,587 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/cas].[cas]] (http-/0.0.0.0:8443-3) JBWEB000236: Servlet.service() for servlet cas threw exception: java.lang.ClassNotFoundException: org.slf4j.impl.Slf4jLogger from [Module "deployment.cas.war:main" from Service Module Loader]at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:213) [jboss-modules.jar:1.3.6.Final-redhat-1]at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:459) [jboss-modules.jar:1.3.6.Final-redhat-1]at org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:408) [jboss-modules.jar:1.3.6.Final-redhat-1]at org.jboss.modules.ConcurrentClassLoader.performLoadClass(ConcurrentClassLoader.java:389) [jboss-modules.jar:1.3.6.Final-redhat-1]at org.jboss.modules.ConcurrentClassLoader.loadClass(ConcurrentClassLoader.java:134) [jboss-modules.jar:1.3.6.Final-redhat-1]at java.lang.Class.forName0(Native Method) [rt.jar:1.7.0_79]at java.lang.Class.forName(Class.java:274) [rt.jar:1.7.0_79]at java.io.ObjectInputStream.resolveClass(ObjectInputStream.java:625) [rt.jar:1.7.0_79]at org.hibernate.internal.util.SerializationHelper$CustomObjectInputStream.resolveClass(SerializationHelper.java:369) [hibernate-core-4.3.10.Final.jar:4.3.10.Final]at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1612) [rt.jar:1.7.0_79]at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1517) [rt.jar:1.7.0_79]at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1771) [rt.jar:1.7.0_79]at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1350) [rt.jar:1.7.0_79]

解决方案

在应用中去掉jboss容器自带的slf4j的依赖

1. 在路径/../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)SLF4J: Class path contains multiple SLF4J bindings.14:09:52,145 ERROR [stderr] (ServerService Thread Pool -- 158) SLF4J: Found binding in [vfs:/content/cas.war/WEB-INF/lib/cas-server-core-4.1.3.jar/org/slf4j/impl/StaticLoggerBinder.class]14:09:52,145 ERROR [stderr] (ServerService Thread Pool -- 158) SLF4J: Found binding in [vfs:/content/cas.war/WEB-INF/lib/log4j-slf4j-impl-2.3.jar/org/slf4j/impl/StaticLoggerBinder.class]14:09:52,145 ERROR [stderr] (ServerService Thread Pool -- 158) SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.14:09:52,221 ERROR [stderr] (ServerService Thread Pool -- 158) SLF4J: ILoggerFactory to be used for logging is: org.apache.logging.slf4j.Log4jLoggerFactory14:09:52,221 ERROR [stderr] (ServerService Thread Pool -- 158) SLF4J: Actual binding is of type [org.slf4j.impl.CasLoggerFactory]14:09:52,221 ERROR [stderr] (ServerService Thread Pool -- 158) SLF4J: The following set of substitute loggers may have been accessed14:09:52,221 ERROR [stderr] (ServerService Thread Pool -- 158) SLF4J: during the initialization phase.

尝试解决此问题

首先我们在的根目录下，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？

修改pom.xml

<plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-war-plugin</artifactId><configuration><warName>cas</warName><webResources><resource><directory>${basedir}/src/main/webapp/WEB-INF</directory><filtering>true</filtering><targetPath>WEB-INF</targetPath><includes><include>**/web.xml</include></includes></resource></webResources><!--Richard Customized--><!--<packagingExcludes>--><!--WEB-INF/lib/log4j-slf4j-impl-*.jar--><!--</packagingExcludes>--></configuration></plugin>

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
