1.druid.jar、mysql.jar放到%tomcat_home%\lib下
2.%tomcat_home%\conf下配置context.xml配置如下
<Context>
<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/MysqlDataSource"
factory="com.alibaba.druid.pool.DruidDataSourceFactory"
auth="Container"
type="javax.sql.DataSource"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/basicpool?useUnicode=true&characterEncoding=utf-8"
username="root"
password="root"
maxActive="50"
maxWait="10000"
removeabandoned="true"
removeabandonedtimeout="60"
logabandoned="false"
filters="stat"/>
</Context>
如果是jdbc获取jndi数据源
/**
* @ClassName: JdbcUtil
* @Description: Jdbc连接工具类
* @author Iverson
*
*/
public class JdbcUtil {
private static final String MYSQL_DB_JNDINAME="java:comp/env/jdbc/MysqlDataSource";
private static DruidDataSource dsMysql;
static {
try {
//1.初始化名称查找上下文
Context ctx= new InitialContext();
//2.通过JNDI名称知道到DataSource
dsMysql=(DruidDataSource) ctx.lookup(MYSQL_DB_JNDINAME);
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* 获取connection
* @return
*
* @throws Exception
*/
public static Connection getConnection()throws Exception{
return dsMysql.getConnection();
}
}
如果是spring配置
<!-- 引入外部文件 -->
<context:property-placeholder location="classpath:jdbc.properties" />
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="${jndiName}"/>
</bean>
<!-- 事务 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 开启事务注解 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
jdbc.properties
jndiName=java:comp/env/jdbc/MysqlDataSource
