  WEB

  设置默认编码

  <subsystem xmlns="urn:jboss:domain:undertow:4.0">
  ...
  <servlet-container name="default" default-encoding="UTF-8" use-listener-encoding="true">
      <jsp-config/>
      <websockets/>
  </servlet-container>
  ...
  </subsystem>

  配置ajp-listener和instance-id

  <subsystem xmlns="urn:jboss:domain:undertow:4.0" instance-id="asdapp1">
  <buffer-cache name="default"/>
  <server name="default-server">
      <ajp-listener name="ajp" socket-binding="ajp" scheme="http"/>
      <http-listener name="default" socket-binding="http" redirect-socket="https" enable-http2="true"/>

      ...
  </server>
  ...
  </subsystem>

  JSF 1.2

  EAP 7不支持JSF 1.2，可从EAP 6将JSF 1.2 Module(包含javax.faces.api，com.sun.jsf-impl，org.jboss.as.jsf-injection)迁移过来，module.xml内容无需更改，建议修改一下module版本urn:jboss:module:1.5
  如部署使用的ear包，在jboss-deployment-structure.xml中增加如下配置：

  <jboss-deployment-structure>
  <deployment>
      <exclusions>
          <module name="javax.faces.api"/>
          <module name="com.sun.jsf-impl"/>
          <module name="org.jboss.as.jsf-injection"/>
      </exclusions>
      <dependencies>
          <module name="javax.faces.api" slot="1.2" export="true"/>
          <module name="com.sun.jsf-impl" slot="1.2" export="true"/>

Richfaces 3.3

因EAP 7的servlet版本是3.1，fileUpload组件不能使用，需要使用getParts方法重写MultipartRequest实现。

}

另外，Richfaces 3.3.4.Final fileupload组件页面显示有中文乱码问题，需要修改FileUploadRendererBase的initLabels方法，删除value = dumpingWriter.toString();这一行。

Hibernate 3.5

• 强烈建议升级到Hibernate 5，如确实不能升级，需创建一个3.5 module，放入依赖包，module配置如下：

  </dependencies>
  </module>

• jboss-deployment-structure.xml中排除org.hibernate，引入3.5

  <jboss-deployment-structure>
  <deployment>
      <exclusions>
          <module name="org.hibernate"/>
      </exclusions>
      <dependencies>
          <module name="org.hibernate" slot="3.5" export="true"/>
          <module name="org.antlr" export="true"/>
          <module name="org.javassist" export="true"/>
      </dependencies>
  </deployment>
  <sub-deployment name="ejb.jar">
      <exclusions>
          <module name="org.hibernate"/>
      </exclusions>
      <dependencies>
          <module name="org.hibernate" slot="3.5"/>
          <module name="org.javassist"/>
      </dependencies>
  </sub-deployment>
  </jboss-deployment-structure>

• 修改persistence.xml

  <?xml version="1.0" encoding="UTF-8"?>
  <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0">
  <persistence-unit name="schedule">

      <jta-data-source>java:jboss/datasources/scheduleDatasource</jta-data-source>
      <class>...</class>
      <properties>
          <property name="jboss.as.jpa.providerModule" value="org.hibernate:3.5"/>
          <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
          ...
      </properties>
  </persistence-unit>
  </persistence>

  HornetQ

  EAP 7 使用了ActiveMQ Artemis取代了HornetQ，原Message-Driven Bean不需更改，需更改配置和客户端调用代码。

• jms-destinations
  EAP 6中jms-destinations配置如下：

  <hornetq-server>
  ...
  <jms-destinations>
   <jms-queue name="testQueue">
      <entry name="queue/test"/>
       <entry name="java:jboss/exported/jms/queue/test"/>
    </jms-queue>
  </jms-destinations>
  ...
  </hornetq-server>

  更改为：

  <subsystem xmlns="urn:jboss:domain:messaging-activemq:2.0">
  <server name="default">
   ...
   <jms-queue name="testQueue" entries="queue/test java:jboss/exported/jms/queue/test"/>
   ...
  </server>
  </subsystem>

• security
  如不启用security，增加如下配置：

  <subsystem xmlns="urn:jboss:domain:messaging-activemq:2.0">
  <server name="default">
   <security enabled="false"/>
   ...
  </server>
  </subsystem>

• Dependency

  <dependency>
  <groupId>org.jboss.spec.javax.json</groupId>
  <artifactId>jboss-json-api_1.0_spec</artifactId>
  <scope>provided</scope>
  </dependency>

• org.apache.activemq.artemis module取代org.hornetq
• 客户端代码
  EAP 7，默认connector从remote改为http-remoting，使用undertow default http-listener、http端口，这也是推荐的方式：

  <subsystem xmlns="urn:jboss:domain:messaging-activemq:2.0">
  <server name="default">
  ...
  <http-connector name="http-connector" socket-binding="http" endpoint="http-acceptor"/>
  <http-acceptor name="http-acceptor" http-listener="default"/>
  ...
  </server>
  </subsystem>

  <subsystem xmlns="urn:jboss:domain:undertow:4.0">
  ...
  <server name="default-server">
     <ajp-listener name="ajp" socket-binding="ajp"/>
     <http-listener name="default" socket-binding="http" redirect-socket="https" enable-http2="true"/>
     ...
  </server>
  ...
  </subsystem>

  客户端代码要做以下修改：remote connection port从4447改为8080，PROVIDER_URL从remote://localhost:4447改为http-remoting://localhost:8080。INITIAL_CONTEXT_FACTORY从org.jboss.naming.remote.client.InitialContextFactory改为org.wildfly.naming.client.WildFlyInitialContextFactory。
  EAP 6:

  java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory
  java.naming.provider.url=remote://localhost:4447

  EAP 7:

  java.naming.factory.initial=org.wildfly.naming.client.WildFlyInitialContextFactory
  java.naming.provider.url=http-remoting://localhost:8080

  EJB

• Connector
  EAP 7，默认connector从remote改为http-remoting，使用undertow default http-listener、http端口。
  EAP 6:

  <subsystem xmlns="urn:jboss:domain:remoting:1.2">
  <connector name="remoting-connector" socket-binding="remoting" security-realm="ApplicationRealm"/>
  </subsystem>

  EAP 7:

  <subsystem xmlns="urn:jboss:domain:remoting:4.0">
  <endpoint/>
  <http-connector name="http-remoting-connector" connector-ref="default" security-realm="ApplicationRealm"/>
  </subsystem>

• jboss-ejb-client.properties
  EAP 6:

  remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
  remote.connections=default
  remote.connection.default.protocol=remote
  remote.connection.default.host=localhost
  remote.connection.default.port=4447
  remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
  remote.connection.default.username=quickuser
  remote.connection.default.password=quick-123

  EAP 7:

  remote.connections=default
  remote.connection.default.protocol=http-remoting
  remote.connection.default.host=localhost
  remote.connection.default.port=8080
  remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
  remote.connection.default.username=quickuser
  remote.connection.default.password=quick-123

• 客户端代码
  EAP 6:

  java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory
  java.naming.provider.url=remote://localhost:4447

  EAP 7:

  java.naming.factory.initial=org.wildfly.naming.client.WildFlyInitialContextFactory
  java.naming.provider.url=http-remoting://localhost:8080

• Standalone Client
  EAP 7.1引入新的配置文件wildfly-config.xml，统一了所有客户端的配置，在standalone client中推荐使用这种方式。wildfly-config.xml放在classpath或META-INF目录下，也可用-Dwildfly.config.url指定路径（优先级：wildfly.config.url > classpath > META-INF）。
  wildfly-config.xml:

  <?xml version="1.0" encoding="UTF-8"?>
  <configuration>
  <authentication-client xmlns="urn:elytron:1.0.1">
      <authentication-rules>
          <rule use-configuration="ejb"/>
      </authentication-rules>
      <authentication-configurations>
          <configuration name="ejb">
              <sasl-mechanism-selector selector="DIGEST-MD5"/>
              <set-user-name name="quickuser"/>
              <credentials>
                  <clear-password password="quick-123"/>
              </credentials>
              <providers>
                  <use-service-loader/>
              </providers>
              <set-mechanism-realm name="ApplicationRealm"/>
          </configuration>
      </authentication-configurations>
  </authentication-client>
  </configuration>

  使用wildfly-config.xml时的Java代码：

  Properties properties = new Properties();
  properties.put(Context.INITIAL_CONTEXT_FACTORY, WildFlyInitialContextFactory.class.getName());
  properties.put(Context.PROVIDER_URL, "http-remoting://localhost:8080");
  Context context = new InitialContext(properties);
  Object theRemote = context.lookup(jndiName);
  ...

  代码很简单，多个PROVIDER_URL时用逗号分隔。注意运行之前要添加ApplicationRealm用户：

  add-user.sh -a -u quickuser -p quick-123

• Server-to-Server
  利用remote-outbound-connection，在standalone.xml中增加如下配置：
  增加security-realm，密码需经Base64编码

  <management>
  <security-realms>
      <security-realm name="ejb-security-realm">
          <server-identities>
              <secret value="cXVpY2stMTIz"/>
          </server-identities>
      </security-realm>
      ...
  </security-realms>
  ...
  </management>

  配置remote-outbound-connection

  <subsystem xmlns="urn:jboss:domain:remoting:4.0">
  <endpoint/>
  <http-connector name="http-remoting-connector" connector-ref="default" security-realm="ApplicationRealm"/>
  <outbound-connections>
      <remote-outbound-connection name="remote-ejb-connection1" outbound-socket-binding-ref="remote-ejb1" username="quickuser" security-realm="ejb-security-realm" protocol="http-remoting">
          <properties>
              <property name="SASL_POLICY_NOANONYMOUS" value="false"/>
              <property name="SSL_ENABLED" value="false"/>
          </properties>
      </remote-outbound-connection>
  </outbound-connections>
  </subsystem>

  配置Socket

  <socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
  ...
  <outbound-socket-binding name="remote-ejb1">
      <remote-destination host="127.0.0.1" port="8080"/>
  </outbound-socket-binding>
  </socket-binding-group>

  在war的WEB-INF或ear的META-INF中新建文件jboss-ejb-client.xml：

  <jboss-ejb-client xmlns="urn:jboss:ejb-client:1.2">  
  <client-context>  
      <ejb-receivers>  
          <remoting-ejb-receiver outbound-connection-ref="remote-ejb-connection1" connect-timeout="10000"/>  
      </ejb-receivers>  
  </client-context>  
  </jboss-ejb-client>

  Java代码

  Properties props = new Properties();  
  props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");  
  Context context = new javax.naming.InitialContext(props);  
  Object theRemote = context.lookup(jndiName);

  Seam 2.2.2.Final

  seam 2.2可以运行在Jboss EAP 7，同在EAP 6中一样，需修改org.jboss.seam.transaction.Transaction：

  protected javax.transaction.UserTransaction getUserTransaction() throws NamingException
  {
    InitialContext context = Naming.getInitialContext();
    try
    {
       return (javax.transaction.UserTransaction) context.lookup("java:comp/UserTransaction");
    }
    catch (NamingException ne)
    {
       try
       {
          //Embedded JBoss has no java:comp/UserTransaction
          javax.transaction.UserTransaction ut = (javax.transaction.UserTransaction) context.lookup("UserTransaction");
          ut.getStatus(); //for glassfish, which can return an unusable UT
          return ut;
       }
       catch (NamingException nnfe2) {
           // Try the other JBoss location in JBoss AS7
           return (javax.transaction.UserTransaction) context.lookup("java:jboss/UserTransaction");
       }
       catch (Exception e)
       {
          throw ne;
       }
    }
  }

  如使用了seam-resteasy，需排除jaxrs子系统，使用EAP 6中的resteasy版本即可。

  <jboss-deployment-structure>
  <deployment>
      <exclude-subsystems>
          <subsystem name="jaxrs"/>
      </exclude-subsystems>
      ...
  </deployment>
  </jboss-deployment-structure>

  PicketLink

  配置Subsystem

  EAP 7默认是不支持picketlink的，需要配置picketlink subsystem。
  增加extension

  <extensions>
  ...
  <extension module="org.wildfly.extension.picketlink"/>
  ...
  </extensions>

  配置subsystem

  <profile>
  ...
  <subsystem xmlns="urn:jboss:domain:picketlink-federation:2.0"/>
  ...
  </profile>

  配置security-domain

  将EAP 6中相应配置迁移过来即可。

  <security-domain name="sp" cache-type="default">
  <authentication>
      <login-module code="org.picketlink.identity.federation.bindings.jboss.auth.SAML2LoginModule" flag="required"/>
  </authentication>
  </security-domain>
  <security-domain name="idp" cache-type="default">
  <authentication>
      <login-module code="UsersRoles" flag="required">
          <module-option name="usersProperties" value="users.properties"/>
          <module-option name="rolesProperties" value="roles.properties"/>
      </login-module>
  </authentication>
  </security-domain>

  配置jboss-deployment-structure

  <jboss-deployment-structure>
  <deployment>
      <dependencies>
          ...
          <module name="org.picketlink" services="import"/>
      </dependencies>
  </deployment>
  </jboss-deployment-structure>

  注意：必须要添加services="import"。

  配置Federation

  EAP 7，valve不再使用：

  <?xml version="1.0" encoding="UTF-8"?>
  <jboss-web>
  <security-domain>sp</security-domain>
  <valve>
      <class-name>org.picketlink.identity.federation.bindings.tomcat.sp.ServiceProviderAuthenticator</class-name>
      <param>
          <param-name>characterEncoding</param-name>
          <param-value>UTF-8</param-value>
      </param>
  </valve>
  </jboss-web>

  <jboss-web>
  <security-domain>idp</security-domain>
  <context-root>idp-sig</context-root>
  <valve>
      <class-name>org.picketlink.identity.federation.bindings.tomcat.idp.IDPWebBrowserSSOValve</class-name>
  </valve>
  </jboss-web>

  删除valve，参数需迁移到web.xml中：

  <context-param>
  <param-name>org.picketlink.federation.saml.CHARACTER_ENCODING</param-name>
  <param-value>UTF-8</param-value>
  </context-param>

  web.xml中必须配置login-config

  <web-app>
  ...
  <login-config>
  <auth-method>FORM</auth-method>
  </login-config>
  </web-app>

  注意：idp、sp都要配置auth-method
  picketlink.xml sample:

  <PicketLink xmlns="urn:picketlink:identity-federation:config:2.1">
  <PicketLinkSP xmlns="urn:picketlink:identity-federation:config:2.1" BindingType="POST" SupportsSignatures="true"
                ErrorPage="/sso/error.seam" LogOutPage="/sso/logout.seam">
      <IdentityURL>http://localhost:8080/idp-sig/</IdentityURL>
      <ServiceURL>https://localhost:8443/sso/</ServiceURL>
      <KeyProvider ClassName="org.picketlink.identity.federation.core.impl.KeyStoreKeyManager">
          <Auth Key="KeyStoreURL" Value="/test.jks"/>
          <Auth Key="KeyStorePass" Value="store123"/>
          <Auth Key="SigningKeyPass" Value="test123"/>
          <Auth Key="SigningKeyAlias" Value="servercert"/>
          <ValidatingAlias Key="localhost" Value="servercert"/>
      </KeyProvider>
  </PicketLinkSP>
  <Handlers xmlns="urn:picketlink:identity-federation:handler:config:2.1">
      <Handler class="org.picketlink.identity.federation.web.handlers.saml2.SAML2LogOutHandler"/>
      <Handler class="org.picketlink.identity.federation.web.handlers.saml2.SAML2AuthenticationHandler">
          <Option Key="NAMEID_FORMAT" Value="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress"/>
          <Option Key="CLOCK_SKEW_MILIS" Value="120000"/>
      </Handler>
      <Handler class="org.picketlink.identity.federation.web.handlers.saml2.RolesGenerationHandler"/>
      <Handler class="org.picketlink.identity.federation.web.handlers.saml2.SAML2SignatureGenerationHandler"/>
      <Handler class="org.picketlink.identity.federation.web.handlers.saml2.SAML2SignatureValidationHandler"/>
  </Handlers>
  </PicketLink>

  注意：

  1. 如果升级到EAP 7.1.2后使用picketlink可能会报如下错误：
     Error during the logout.: java.lang.NullPointerException
     at org.picketlink.identity.federation.bindings.wildfly.sp.SPFormAuthenticationMechanism.lambda$authenticate$0(SPFormAuthenticationMechanism.java:275)
     建议7.1.3发布后再升级。
  2. Undertow Servlet Container有一属性proactive-authentication，默认为true，会拦截所有含有SAMLResponse参数的请求。当项目中使用了其他custom portal时，将其设为"false";

     <servlet-container name="default" default-encoding="UTF-8" use-listener-encoding="true" proactive-authentication="false">
     <jsp-config/>
     <websockets/>
     </servlet-container>

     Patching EAP

     使用CLI应用、回滚、清除Patch

     Applying a Patch

     patch apply /path/to/downloaded-patch.zip --override-all
     shutdown --restart=true

     Rolling Backe a Patch

     先使用patch history查询出patch id，然后调用rollback命令：

     patch history
     patch rollback --patch-id=PATCH_ID --reset-configuration=TRUE
     shutdown --restart=true

     Clearing Patch History

     多次打Patch后会占用磁盘空间，可进行清理，但当前应用的Patch是不能删除的。

     /core-service=patching:ageout-history
