实战 php调用java类由java类读数据库完成相关操作
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+"
"+"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+"
"+"arr["+i+"]=new BDSort
("+ID+","+ID2+","+NAME+",y);";
i++;
}
sql2="select ID,NAME from ROLE_MANAGE where ID not in(select
ROLSEID from USER_ROLSE_LINK where USERID="+ID2+") order by ID asc ";
stmt2=conss.createStatement();
rst2=stmt2.executeQuery(sql2);
while(rst2.next())
{
ID=rst2.getString("ID");
NAME=rst2.getString("NAME");
rString=rString+"
"+"arr["+i+"]=new BDSort
("+ID+","+ID2+","+NAME+",n);";
i++;
}
}
rstsss=null;
return rString;
}
public static void main(String[] args){
//测试如下
GetUserRolseArray obj1 = new GetUserRolseArray();
