tomcat配置——连接池

1. Tomcat连接池配置

1. 1 Tomcat默认连接池配置

(1)修改conf/server.xml,添加如下内容
<GlobalNamingResources>
<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=" jdbc/connPool"
auth="Container" type="javax.sql.DataSource"
driverClassName="com.mysql.jdbc.Driver"
maxIdle="20"
maxWait="5000" 
username="root" 
password="admin"
url="jdbc:mysql://localhost:3306/bbs"
maxActive="100" 
removeAbandoned="true" 
removeAbandonedTimeout="60"
logAbandoned="true"/> 
</GlobalNamingResources>

(2)修改conf/context.xml,添加如下内容
<ResourceLink name=" jdbc/connPool " global=" jdbc/connPool " type="javax.sql.DataSource"/>

(3)修改web应用的web.xml,添加如下内容
<resource-ref> 
<description>DB Connection</description>
<res-ref-name> jdbc/connPool </res-ref-name> 
<res-type>javax.sql.DataSource</res-type> 
<res-auth>Container</res-auth>
</resource-ref>

1.2 Tomcat c3p0连接池配置

(1)修改conf/server.xml,添加如下内容
<GlobalNamingResources>
<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="jdbc/connPool"
auth="Container" 
description="DB Connection" 
driverClass="com.mysql.jdbc.Driver" 
maxPoolSize="10" 
minPoolSize="2" 
acquireIncrement="2" 
user="root" 
password="root" 
factory="org.apache.naming.factory.BeanFactory" 
type="com.mchange.v2.c3p0.ComboPooledDataSource" 
jdbcUrl="jdbc:mysql://localhost:3306/db?autoReconnect=true" />
</GlobalNamingResources>

(2)修改conf/context.xml,添加如下内容
<ResourceLink name=" jdbc/connPool " global=" jdbc/connPool " type="javax.sql.DataSource"/>

(3)修改web应用的web.xml,添加如下内容
<resource-ref> 
<description>DB Connection</description>
<res-ref-name> jdbc/connPool </res-ref-name> 
<res-type>javax.sql.DataSource</res-type> 
<res-auth>Container</res-auth>
</resource-ref>

2. Tomcat连接池调用方式
(1) Java直接调用
Java代码// 初始化查找命名空间   Context initContext = new InitialContext();  Context envContext = (Context)initContext.lookup("java:/comp/env");   // 找到DataSource  DataSource ds = (DataSource)envContext.lookup("jdbc/connPool");  或
Java代码Context initContext = new InitialContext();  DataSource ds =   (DataSource) initContext.lookup("java:comp/env/jdbc/pooledDS");
(2) 通过Spring方式调用

Xml代码<bean id="dataSource"
class="org.springframework.jndi.JndiObjectFactoryBean">      <property name="jndiName">          <value>java:/comp/env/jdbc/connPool</value>
</property></bean>

3. Resources配置其它说明
Resources的属性可自由添加,其作为type指定的类运行时所需的参数。
