将数据源配置放在Tomcat的config目录下，使用curl工具上传文件

 1.web.xml中的配置

 

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee web-app_2_4.xsd"
version="2.4">
<context-param>
  <param-name>ProxoolConfigFile</param-name>
  <param-value>/WEB-INF/proxool.config</param-value>
</context-param>
<listener>
    <listener-class>com.ProxoolListener</listener-class>
</listener>
<servlet>
    <servlet-name>Admin</servlet-name>
    <servlet-class>org.logicalcobwebs.proxool.admin.servlet.AdminServlet </servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Admin</servlet-name>
    <url-pattern>/admin </url-pattern>
</servlet-mapping>

<servlet>
    <servlet-name>AxxxDispatcher</servlet-name>
    <servlet-class>com.Dispatcher</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>AxxxDispatcher</servlet-name>
    <url-pattern>/axxx/*</url-pattern>
</servlet-mapping>

</web-app>

 2.在proxool.config中的配置

 

proxool.house-keeping-sleep-time=90000
proxool.maximum-connection-lifetime=300000
proxool.maximum-active-time=300000
proxool.prototype-count=5
proxool.maximum-connection-count=10
proxool.minimum-connection-count=1
proxool.test-before-use=true
proxool.house-keeping-sleep-time=60000
proxool.house-keeping-test-sql=select getdate()

3.ProxoolListener中的代码

配置文件中的改动，Tomcat会自动刷新。

 

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.Properties;

import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

import org.logicalcobwebs.proxool.ProxoolFacade;

public class ProxoolListener implements ServletContextListener {
    final static String CONFIGFILE = "ProxoolConfigFile";
    final static String ALIAS = "db.alias";
    final static String HOST = "db.host";
    final static String PORT = "db.port";
    final static String DATABASE = "db.database";
    final static String LOGIN = "db.login";
    final static String PASS = "db.password";
    final static String DIRECTORY = "file.directory";
    public static String path = null ;
    private static String alias;
    public void contextDestroyed(ServletContextEvent arg0) {
        // TODO Auto-generated method stub
        ProxoolFacade.shutdown(0);

    }

    public void contextInitialized(ServletContextEvent ctxEvent) {
        // TODO Auto-generated method stub
        Properties prop = new Properties();
        ServletContext ctx = ctxEvent.getServletContext();
        String configFile = ctx.getInitParameter(CONFIGFILE);
        try {
            prop.load(ctxEvent.getServletContext().getResourceAsStream(configFile));
            System.err.println(prop.getProperty("proxool.house-keeping-test-sql"));
            alias = ctx.getInitParameter(ALIAS);
            String host = ctx.getInitParameter(HOST);
            String port = ctx.getInitParameter(PORT);
            String database = ctx.getInitParameter(DATABASE);
            String login = ctx.getInitParameter(LOGIN);
            String password = ctx.getInitParameter(PASS);
            prop.setProperty("user", login);
            prop.setProperty("password", password);
            String driverClass = "net.sourceforge.jtds.jdbc.Driver";
            String driverUrl = "jdbc:jtds:sqlserver://"+host+":"+port+"/"+database;
            String url = "proxool." + alias + ":" + driverClass + ":" + driverUrl;
            Class.forName("org.logicalcobwebs.proxool.ProxoolDriver");
            ProxoolFacade.registerConnectionPool(url, prop);

            path = ctx.getInitParameter(DIRECTORY);
        }
        catch (Exception e){
            e.printStackTrace();
        }

    }
    public static Connection getConnection()throws SQLException {
        return DriverManager.getConnection("proxool."+alias);
    }

}

4.在tomcat\conf\Catalina\localhost 目录下新建一个配置数据库信息的xml文件

此xml文件的文件名就是项目的文件名，比如myTest.xml，不管path="/path" 或者docBase="D:\app.war"，此时访问的项目名就是 http://127.0.0.1:8080/myTest/。

 

<Context path="/path" reloadable="true" docBase="D:\app.war" workDir="D:\zhao\java\work" >
    <Parameter name="db.alias" value="别名" />
    <Parameter name="db.host" value="127.0.0.1" />
    <Parameter name="db.port" value="1433" />
    <Parameter name="db.database" value="xxxdb" />
    <Parameter name="db.login" value="sa" />
    <Parameter name="db.password" value="sa" />
    <Parameter name="file.directory" value="C:\test\" />
</Context>

 

5.此时启动Tomcat，http://127.0.0.1:8080/path/ 即可以访问。

6.对于需要上传一些文件到该路径的，可以试用curl工具。用doPost的方式上传。

比如使用cmd，打开文件所在目录，键入一下命令即可。

 

curl -k --data-binary @要上传的文件 -H "Content-Type:text/xml;charset=UTF-8"  http://127.0.0.1:8080/path/xxx/

 

7.在Dispatcher中接收文件的代码

 

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.PrintWriter;
import java.io.StringWriter;
import java.io.Writer;
import java.sql.Connection;
import java.sql.SQLException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Enumeration;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.simpleframework.xml.Serializer;
import org.simpleframework.xml.core.Persister;

import com.pansontech.common.DbTransaction;
import com.pansontech.common.db.ProxoolListener;
import com.pansontech.gdlgst.akzon.bean.DELVRY03;
import com.pansontech.gdlgst.akzon.util.ParserUtil;

public class Dispatcher extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        // TODO Auto-generated method stub
        System.err.println("doGet");
        String output="Access Denied!";
        resp.setCharacterEncoding("UTF-8");
        Writer out = resp.getWriter();
        out.write(output);
        out.flush();
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        int len = req.getContentLength();
        byte[] temp = new byte[len];
        Enumeration enu = req.getHeaderNames();
        while (enu.hasMoreElements()){
            String head = (String)enu.nextElement();
            System.err.println(head+":"+req.getHeader(head));
        }
        InputStream is = req.getInputStream();
//      SimpleDateFormat sdf=new SimpleDateFormat("yyyyMMddHHmmss");
//      String path = this.getServletContext().getRealPath("/")+sdf.format(Calendar.getInstance().getTime())+".xml";
//      System.err.println(path);
//      FileOutputStream fos = new FileOutputStream(path);
        int len1 = 0;
        int totalRead = 0;
        //放到byte[] temp中，这样能够保证网络问题引起的文件内容不完整。
        while ((totalRead<len)&&(len1=is.read(temp,totalRead,len - totalRead))!=-1){
//          String input = new String(temp,"UTF-8");
//          System.err.println(input);
            totalRead = totalRead + len1;
        }
//      fos.write(temp,0,totalRead);
//      fos.close();
    }
}
