tomcat embedded + sqlite

tomcat5 embed 直接解压就可以用了，5.0.x 用jdk1.4，5.5.x用jkd1.5，不过启动要靠java 程序(它实际上是一些 jar 包),也就是你可以把它导入web项目里，这个web项目就包含了服务器，启动时设置项目的路径就可以了


sqlite 文件很小，就一个（几百K），也需要手动或程序启动


启动tomcat embed 的类如下:

  
  
import org.apache.catalina.Context;
import org.apache.catalina.Engine;
import org.apache.catalina.Host;
import org.apache.catalina.LifecycleException;
import org.apache.catalina.connector.Connector;
import org.apache.catalina.startup.Embedded;
  
public class Run {  
  
    private static Embedded tomcat = null;  
    public static void main(String[] args) {  
        // TODO Auto-generated method stub  
        initEmbedded();  
        initShutdownHook();  
        startTomcat();  
    }  
  
    private static void startTomcat(){  
        try {  
            tomcat.start();  
        } catch (LifecycleException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        }  
    }  
    private static void initShutdownHook(){  
        Runtime.getRuntime().addShutdownHook(new Thread(){  
            public void run(){  
                try {  
                    tomcat.stop();  
                } catch (LifecycleException e) {  
                    // TODO Auto-generated catch block  
                    e.printStackTrace();  
                }  
            }  
        });  
    }  
    private static void initEmbedded() {  
        tomcat = new Embedded();  
        tomcat.setCatalinaHome("D:\\apache-tomcat-5.5.28-embed");  //tomcat embed 路径
          
        Engine engine = tomcat.createEngine();  
        engine.setName("MyEngine");  
  
        Host host = tomcat.createHost("localhost", "D:\\apache-tomcat-5.5.28-embed\\webapps");  // web站点根目录
        Context myContext = tomcat.createContext("/test", "E:\\newworkspace\\Fbote");  //工程目录（要编译好的，我是用eclipse编译好的）
          
        host.addChild(myContext);  
        engine.addChild(host);  
        engine.setDefaultHost("localhost");  
        tomcat.addEngine(engine);  
        Connector connector = tomcat.createConnector("localhost", 8080, false);  //端口
        tomcat.addConnector(connector);  
    }  
  
}  

sqlite 使用很简单,（测试时在windows）下测试：

解压 -> cmd -> cd 所在目录:

sqlite3.exe Mydb.db
create table user(id integer primary key,name varchar(222));
insert into user(1,'elmer');
.schema

(此时就建好了Mydb 数据库和 user 表，并添加了一条数据)

select * from user 

就会出现

1|elmer

jsp 连接时用:

<%@ page contentType="text/html; charset=utf-8" pageEncoding="utf-8" language="java" import="java.sql.*"%>
<%
request.setCharacterEncoding("utf-8");
String body = request.getParameter("body");

try {
Class.forName("org.sqlite.JDBC");
Connection conn = DriverManager.getConnection("jdbc:sqlite:/d:/test.db");
Statement stmt = conn.createStatement(ResultSet.TYPE_FORWARD_ONLY,ResultSet.CONCUR_READ_ONLY);

String sql = "INSERT INTO ttable(id, name) VALUES('1', '" + body + "')";
stmt.executeUpdate(sql);

stmt.close();
conn.close();
} catch(Exception e) {
out.println(e.getMessage());
return;
}
%>

如果是用连接池可以在struts-config.xml中陪置如下：

<data-sources>
          <data-source key="org.apache.struts.action.DATA_SOURCE"
           type="org.apache.commons.dbcp.BasicDataSource">
           <set-property property="autoCommit" value="true" />
           <set-property property="description"  value="sqlite Data Source" />
           <set-property property="driverClassName" value="org.sqlite.JDBC" />
           <set-property property="maxCount" value="100" />
           <set-property property="minCount" value="20" />
           <set-property property="maxWait" value="1000" />
           <set-property property="url"
            value="jdbc:sqlite:/D:/sqlite/fbote.db" />
          </data-source>
        </data-sources>

上面为测试通过的,下面是其他一些关于 tomcat embed 的例了，没测试过
