因为要运行众多的应用，所以选择了domain的方式，除特别说明，均指domain.xml的配置

推荐个不错的关于Jboss的网站：http://www.mastertheboss.com/

1、关于UTF-8编码的配置：

<system-properties>

<property name="java.net.preferIPv4Stack" value="true"/>

<property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8"/>

<property name="org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING" value="true"/>

</system-properties>

2、关于中文验证码乱码的配置：

安装fontconfig

拷贝汉字自体到/usr/share/fonts目录,如：cjkuni-ukai  cjkuni-uming  dejavu   simsunb.ttf  windows  wqy-zenhei这些自体 ，再重启jboss

3、JVM相关配置：

<server-group name="xxx" profile="default">

<jvm name="xxx">

<heap size="4096m" max-size="4096m"/>

<permgen size="1024m" max-size="1024m"/>

<jvm-options>

<option value="-server"/>

<option value="-XX:+UseParallelGC"/>

<option value="-XX:+UseParallelGC"/>

<option value="-XX:+PrintGCDetails"/>

</jvm-options>

</jvm>

<socket-binding-group ref="full-sockets"/>

</server-group>

4、Datasource配置,主要是连接池、连接超时、查询缓存等配置：

<xa-datasource jndi-name="java:/jdbc/xxx" pool-name="xxx" enabled="true" use-ccm="true">

<xa-datasource-property name="URL">

jdbc:mysql://xx.xx.xx.xx:3306/xx

</xa-datasource-property>

<driver>com.mysql</driver>

<xa-pool>

<min-pool-size>20</min-pool-size>

<max-pool-size>1000</max-pool-size>

<is-same-rm-override>false</is-same-rm-override>

<interleaving>false</interleaving>

<pad-xid>false</pad-xid>

<wrap-xa-resource>false</wrap-xa-resource>

</xa-pool>

<security>

<user-name>xxx</user-name>

<password>xxx</password>

</security>

<validation>

<validate-on-match>false</validate-on-match>

<background-validation>false</background-validation>

</validation>

<timeout>

<idle-timeout-minutes>30</idle-timeout-minutes>

<query-timeout>60</query-timeout>

</timeout>

<statement>

<prepared-statement-cache-size>80</prepared-statement-cache-size>

<share-prepared-statements>true</share-prepared-statements>

</statement>

</xa-datasource>

5、数据库连接驱动配置：

[root@app1 ~]# ls /opt/jboss-as-7.1.1.Final/modules/com/mysql/main/

module.xml  mysql-connector-java-5.1.18.jar  mysql-connector-java-5.1.18.jar.index

module.xml内容：

<?xml version="1.0" encoding="UTF-8"?>

<module xmlns="urn:jboss:module:1.0" name="com.mysql">

<resources>

<resource-root path="mysql-connector-java-5.1.18.jar"/>

</resources>

<dependencies>

<module name="javax.api"/>

<module name="javax.transaction.api"/>

</dependencies>

</module>

domain.xml：

<drivers>

<driver name="mysql" module="com.mysql"/>

<driver name="com.mysql" module="com.mysql">

<xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>

</driver>

</drivers>

6、Http最大连接数设置

<connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http" max-connections="1000"/>
