JNDI+Tomcat配置数据源的两种方式

非全局jndi配置步骤 ：此种配置方式不需要在server.xml中配置数据源，而只在tomcat/conf/Catalina/localhost下的启动配置中配置即可。注意红色字体名称必须和相同。
 
0、需要在tomcat/common/lib下加入数据库连接的jar包

1、web.xml配置
 



<resource-ref>

     <description>my DB Connection</description>

     <res-ref-name>mydataSource </res-ref-name>   

     <res-type>javax.sql.DataSource</res-type>

     <res-auth>Container</res-auth>

 </resource-ref> 


2、applicationContext.xml下配置
 


<bean id="dataSource"

    class="org.springframework.jndi.JndiObjectFactoryBean">

    <property name="jndiName" value="java:comp/env/mydataSource " />

</bean> 


3、在tomcat的conf下的localhost下的配置如下
 



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

<Context docBase="F:/workspace/cuapp/WebRoot" path="cuapp" reloadable="false">

<Resource name="mydataSource" auth="Container" type="javax.sql.DataSource"

                   url="jdbc:oracle:thin:@192.168.2.104:1521:ora10g"

                driverClassName="oracle.jdbc.driver.OracleDriver"

                password="aa"

                username="aa"

                initialSize="2"

                maxActive="3"

                maxIdle="1"

                minIdle="1"

                maxWait="10000"

                removeAbandoned="true"

                logAbandoned="true"

                removeAbandonedTimeout="60"

                timeBetweenEvictionRunsMillis="900000"

                minEvictableIdleTimeMillis="1800000"

                numTestsPerEvictionRun="100"

                validationQuery="select count(0) from dual"

                poolPreparedStatements="true"

                maxOpenPreparedStatements="100"/>

</Context> 



全局jndi配置 ：此种配置需要在server.xml中配置数据源。 
 
0、需要在tomcat下加入数据库连接的jar包

1、web.xml配置
 



<resource-ref>

    <description>my DB Connection</description>

    <res-ref-name>mydataSource </res-ref-name>   must be same as server.xml

    <res-type>javax.sql.DataSource</res-type>

    <res-auth>Container</res-auth>

</resource-ref> 


2、applicationContext.xml下配置
 



<bean id="dataSource"

    class="org.springframework.jndi.JndiObjectFactoryBean">

    <property name="jndiName" value="java:comp/env/mydataSource " />

</bean> 


3、server.xml中配置为
 


<!-- Global JNDI resources -->

 <GlobalNamingResources>

   <!-- Test entry for demonstration purposes -->

   <Environment name="simpleValue" type="java.lang.Integer" value="30"/>

   <!-- Editable user database that can also be used by

        UserDatabaseRealm to authenticate users -->

   <Resource name="UserDatabase" auth="Container"

             type="org.apache.catalina.UserDatabase"

      description="User database that can be updated and saved"

          factory="org.apache.catalina.users.MemoryUserDatabaseFactory"

         pathname="conf/tomcat-users.xml" />

   <Resource name="mydataSource" auth="Container" type="javax.sql.DataSource"

                               url="jdbc:oracle:thin:@192.168.2.104:1521:ora10g"

                           driverClassName="oracle.jdbc.driver.OracleDriver"

                           password="aa"

                           username="aa"

                           initialSize="5"

                           maxActive="10"

                           maxIdle="5"

                           minIdle="2"

                           maxWait="10000"

                           removeAbandoned="true"

                           logAbandoned="true"

                           removeAbandonedTimeout="60"

                           timeBetweenEvictionRunsMillis="900000"

                           minEvictableIdleTimeMillis="1800000"

                           numTestsPerEvictionRun="100"

                           validationQuery="select count(0) from dual"

                           poolPreparedStatements="true"

                           maxOpenPreparedStatements="100"/>

 </GlobalNamingResources> 


4、tomcat/conf下localhost下的配置如下
 




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

<Context docBase="F:/workspace/cuapp/WebRoot" path="xj-adminportal" reloadable="false">

    <ResourceLink name="mydataSource " global="mydataSource " type="javax.sql.DataSource"/>

</Context>
