| 1. Find the context.xml file in the conf folder of the Tomcat6.0 installation directory,
then open the context.xml, and add the following content between the tags <context></<context>: (For easy understanding, I made the configuration more detailed notes)
<Resource name="jdbc/books"
auth="Container"
type="javax.sql.DataSource"
driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
url="jdbc:sqlserver://localhost:1433;DatabaseName=books"
username="sa"
password="accp"
maxActive="100"
maxIdle="30"
maxWait="10000" />

1) name: specifies the JNDI name of the Resource
2) auth : specifies the Manager that manages the Resource
(Container: created and managed by the container | Application: created and managed by the Web application)
3) type: specifies the Java class to which the Resource belongs4
) maxActive: specifies the maximum number of database connections that are active in the connection pool
5) maxIdle: specifies the maximum number of database connections that are idle in the

7) username: database username
8) password: database password
9) driverClassName: database connection driver class name
10) url: database connection string --JDBC获取
Context it = new InitialContext();
DataSource ds = (DataSource) it.lookup("java:comp/env/jdbc/books");
Connection conn = ds.getConnection(); --Spring configuration <bean id="dataSource"
