Homephp教程php手册实战php调用java类由java类读数据库完成相关操作(Inber Write)

数据|数据库

1 建立系统ODBC 数据源photo(本次使用的是Oracle 9i,详细配置如有不懂这处再和我联系)
2 编译DataBaseConnection.java文件 将其编译文件放入到PHP支持的类文件目录中

package com.inberkong.util;
/*******************************************************
 * Programe File :复件缓冲池DataBaseConnection.java
 * Creat    Date :3/28/2005(MM-DD-YYYY)
 * Creat By  :InberKong(GongYingBin)
 * LastModifyDate :3/28/2005(MM-DD-YYYY)
 * ModifyBy  :InberKong(GongYingBin)
 *  Function  :Get the Oracle DataBaseConnectionPool
 //一个用于查找数据源的工具类。
 
 *******************************************************/
import java.sql.*;
//连接数据库的工具类。
public class DataBaseConnection
{
 /**
  *一个静态方法,返回一个数据库的连接。
  */
 public static Connection getConnection()
 {

  Connection con=null;

     try
     {
 Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
       con=DriverManager.getConnection("jdbc:odbc:photo","photo","inberkong");//数据源连接信息    

  }
  catch(Exception e)
  {
   e.printStackTrace();
  }
  return con;
 }
}

3 编译读数据表的处理类同样将处理类放入PHP调用的Java类目录
这是一个读取用户角色表 返回用户与角色间关系的JS数组的处理类 GetUserRolseArray.java
注:读程序时不需要关心相关的表结构,可只关心整个调用的处理过程。
package com.inberkong.processBean;
import java.lang.*;
import java.sql.*;
import java.util.*;
import java.io.*;
import com.inberkong.util.DataBaseConnection;
public  class GetUserRolseArray
{
 private Connection conss;
 private Statement stmtsss=null;
 private Statement stmt2=null,stmt3=null;
 private ResultSet rstsss=null;
 private ResultSet rst2=null,rst3=null;
    private String sqlss="";
    private String sql2="",sql3="";
    private String rString="";
    private String ID,ID2;
    private String NAME;
    private int i=0;
 public GetUserRolseArray()
 {
  try
  { 
 
  this.conss=DataBaseConnection.getConnection();
     }
    catch(Exception e)
    {
    
    }

  //DataBaseConnection.getConnection();
 }
 protected void finalize() throws Throwable
 {
 
  //
 //super.finalize(); 
 //System.out.println("inberkong");
 closeCON();
 
 }      
   public  String  getUserRolseArray() throws Exception
     {
      //exePtempfunction();
     
      sqlss="SELECT ID,NAME FROM ADMIN WHERE 1=1 AND STATE!=0 AND  USERTYPE!='0'

ORDER BY ID DESC";     
      //外部用户不参于后加角色管理
      stmtsss=conss.createStatement();
      rstsss=stmtsss.executeQuery(sqlss);    
      while (rstsss.next())
      {
       ID=rstsss.getString("ID");
       ID2=ID;
      
       NAME=rstsss.getString("NAME");
       rString=rString+"\n"+"arr["+i+"]=new BDSort

('"+ID+"','00','"+NAME+"','');";
       i++;
      
       sql3="select ID,NAME from ROLE_MANAGE  where ID in( select ROLSEID

from USER_ROLSE_LINK where USERID="+ID2+") order by ID asc ";
       stmt3=conss.createStatement();
       rst3=stmt3.executeQuery(sql3);
       while(rst3.next())
       {
      
       ID=rst3.getString("ID");
            
       NAME=rst3.getString("NAME");
       rString=rString+"\n"+"arr["+i+"]=new BDSort

('"+ID+"','"+ID2+"','"+NAME+"','y');";
        i++;       
       }
