tomcat创建连接池及helpDB类连接方法的书写

1、tomcat中sever配置

<Resource auth="Container" driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"

factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" initialSize="10"

jdbcInterceptors="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;

org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer" jmxEnabled="true"

logAbandoned="true" maxActive="100" maxWait="10000" minEvictableIdleTimeMillis="30000"

minIdle="10" name="jdbc/myweb" password="sa" removeAbandoned="true"

removeAbandonedTimeout="60" testOnBorrow="true" testOnReturn="false" testWhileIdle="true"

timeBetweenEvictionRunsMillis="30000" type="javax.sql.DataSource"

url="jdbc:sqlserver://192.168.0.1:4643;DatabaseName=test"

username="sa" validationInterval="30000" validationQuery="SELECT 1"/>

以上放在 此标签之内：<GlobalNamingResources> </GlobalNamingResources>

2、context中配置

<ResourceLink global="jdbc/SJHIS" name="jdbc/myweb" type="javax.sql.DataSource" />

以上放在此标签下：<WatchedResource>WEB-INF/web.xml</WatchedResource>

3、创建一个调用连接的类，类中的连接方法如下：

public Connection GetConnect(){

try {

DataSource ds = null;

Context initCtx = new InitialContext();

ds =(DataSource)initCtx.lookup("java:comp/env/jdbc/myweb");

return ds.getConnection();

} catch (NamingException e) {

e.printStackTrace();

return null;

} catch (SQLException e) {

e.printStackTrace();

return null;

}

}
