java环境2

一，resin 相关

resin使用mysql的JNDI数据源

1.配置conf/resin.conf文件，在

< resource-ref >
< res-ref-name > jdbc/test </ res-ref-name >
< res-type > javax.sql.DataSource </ res-type >
< init-param driver-name ="com.caucho.jdbc.mysql.Driver" />
< init-param url ="jdbc:mysql_caucho://localhost:3306/test" />
< init-param user ="" />
< init-param password ="" />
< init-param max-connections ="20" />
< init-param max-idle-time ="30" />
</ resource-ref >

下输入自己的数据库配置

< resource-ref >
< res-ref-name > jdbc/pms </ res-ref-name >
< res-type > javax.sql.DataSource </ res-type >
< init-param driver-name ="com.mysql.jdbc.Driver" />
< init-param url ="jdbc:mysql://server:3306/pms" />
< init-param user ="username" />
< init-param password ="password" />
< init-param max-connections ="20" />
< init-param max-idle-time ="30" />
</ resource-ref >

2.编写test.jsp文件，显示node表的前两个字段数据：

<% @page import = ' java.sql.*,javax.sql.*,javax.naming.* ' %>
<%
Contextic = new InitialContext();
DataSourceds = (DataSource)ic.lookup( " java:comp/env/jdbc/pms " );

Connectionconn = ds.getConnection();

try {
Statementstmt = conn.createStatement();
ResultSetrs = stmt.executeQuery( " select*fromnode " );
while (rs.next()){ %>
<%= rs.getString( 1 ) %> <%= rs.getString( 2 ) %>< br ><%
}
} finally {
conn.close();
}
%>

3.在ibatis的sql-map-config.xml进行jndi配置

< transactionManager type ="JDBC" >
< dataSource type ="JNDI" >
< property name ="DataSource" value ="java:comp/env/jdbc/pms" />
</ dataSource >
</ transactionManager >
