hibernate在tomcat7.X下配置mysql数据源_MySQL

4.在你的工程项目的web.xml中加入。

tomcat datasource test,one mysql datasource
jdbc/TestDB
javax.sql.DataSource
Container

5.在hibernate.cfg.xml文件中配置数据库连接，这个有很多教程，此处便不再详述。

另外，注意数据源只有在web项目中才可以使用。

再次出来写个简单的servlet来输出hibernate 的session对象：

代码如下：

packagecom.amaker.servlet;

importjava.io.IOException;

importjava.io.PrintWriter;

importjavax.servlet.ServletException;

importjavax.servlet.http.HttpServlet;

importjavax.servlet.http.HttpServletRequest;

importjavax.servlet.http.HttpServletResponse;

importorg.hibernate.Session;

importcom.amaker.util.HibernateUtil;

@SuppressWarnings("serial")

publicclasstestServletextendsHttpServlet {

* Constructor of the object.

publictestServlet() {

super();

* Destruction of theservlet.

publicvoiddestroy() {

super.destroy();// Just puts "destroy" string in log

* The doGet method of theservlet.

* This method is called when a form has its tag value method equals to get.

*@paramrequest the request send by the client to the server

*@paramresponse the response send by the server to the client

*@throwsServletException if an error occurred

*@throwsIOException if an error occurred

publicvoiddoGet(HttpServletRequest request, HttpServletResponse response)

throwsServletException, IOException {

HibernateUtil util =newHibernateUtil();

//HibernateUtil 类用来返回一个Session

对象，很简单，相信大家可以搞定。

response.setContentType("text/html");

PrintWriter out = response.getWriter();

out.println("");

out.println("");

out.println(" ");

out.println(" ");

out.println(" ");

out.println("");

publicvoiddoPost(HttpServletRequest request, HttpServletResponse response)

throwsServletException, IOException {

doGet(request, response);

* Initialization of theservlet.

*@throwsServletException if an error occurs

publicvoidinit()throwsServletException {

}

访问结果如图，返回一个session对象。
