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（增加连接池配置文件，以项目名命名）。注意红色字体名称必须和相同。

1、需要在tomcat/lib下加入数据库连接的jar包  
  
2、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>

3、applicationContext.xml下配置

4、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。

1、需要在tomcat下加入数据库连接的jar包  
  
2、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>

3、applicationContext.xml下配置

4、server.xml中配置为

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

5、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>
