Spring Security2是一套安全验证框架，与它的前一个版本acegi相比，简化了很多配置的工作，因为很多配置都已经自动完成了。下面就开始体验一下Spring Security2配置的简单与强大。在本文中将介绍Spring Security2的基本使用。 1, 新建一个J2EE Web工程。 2, 添加必须的jar包放到classpath中： spring.jar spring-security-core-2.0.4.jar spring-security-core-tiger-2.0.4.jar 3, 添加Spring Security的配置文件。在WEB-INF目录下建Application-Security.xml文件。并加入以下配置信息。 <?xml version=”1.0″ encoding=”UTF-8″?> <beans:beans xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance              xmlns=http://www.springframework.org/schema/security              xmlns:beans=http://www.springframework.org/schema/beans              xsi:schemalocation=”http://www.springframework.org/schema/beans            &#160; http://www.springframework.org/schema/beans/spring-beans-2.5.xsd            &#160; http://www.springframework.org/schema/security            &#160; http://www.springframework.org/schema/security/spring-security-2.0.4.xsd”>                                             &#160;    <http auto-config=”true”>                                        <intercept-url access=”ROLE_USER” pattern=”/**” />                            </http>                                                <authentication-provider>                                    <user-service>                                            <user authorities=”ROLE_USER, ROLE_ADMIN” password=”hand” name=”hand” />                                            <user [...]

在项目中使用的Oracle JDBC版本为Oracle JDBC Driver version – 9.0.2.0.0，由于使用了Hibernate，所以一直没有发现使用native sql查询时时间类型会丢失时分秒。测试程序如下：
public class TestDate {
public static void main(String[] args) {

try {
Class.forName(”oracle.jdbc.driver.OracleDriver”);
try {
connection = DriverManager.getConnection(”jdbc:oracle:thin:@localhost:1521:xe”,”exthosf”,”exthosf”);
PreparedStatement ps=connection.prepareStatement(”SELECT sysdate FROM dual”);
ResultSet rs=ps.executeQuery();
while(rs.next())
System.out.println(rs.getObject(1));
} catch (SQLException e) {
e.printStackTrace();
}
if (connection != null) {
System.out.println(”取得连接 ”);
} else {
System.out.println(”无法取得数据库连接！”);
}
} catch (ClassNotFoundException e) [...]
