实战 php调用java类由java类读数据库完成相关操作

Jun 13, 2016 am 10:33 AM
java odbc php Finish Actual combat Establish operate database data source Related system transfer

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+" "+"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();

Composer: Aiding PHP Development Through AI Composer: Aiding PHP Development Through AI Apr 29, 2025 am 12:27 AM

AI can help optimize the use of Composer. Specific methods include: 1. Dependency management optimization: AI analyzes dependencies, recommends the best version combination, and reduces conflicts. 2. Automated code generation: AI generates composer.json files that conform to best practices. 3. Improve code quality: AI detects potential problems, provides optimization suggestions, and improves code quality. These methods are implemented through machine learning and natural language processing technologies to help developers improve efficiency and code quality.

How to use MySQL functions for data processing and calculation How to use MySQL functions for data processing and calculation Apr 29, 2025 pm 04:21 PM

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Composer: The Package Manager for PHP Developers Composer: The Package Manager for PHP Developers May 02, 2025 am 12:23 AM

Composer is a dependency management tool for PHP, and manages project dependencies through composer.json file. 1) parse composer.json to obtain dependency information; 2) parse dependencies to form a dependency tree; 3) download and install dependencies from Packagist to the vendor directory; 4) generate composer.lock file to lock the dependency version to ensure team consistency and project maintainability.

How to implement singleton pattern in C? How to implement singleton pattern in C? Apr 28, 2025 pm 10:03 PM

Implementing singleton pattern in C can ensure that there is only one instance of the class through static member variables and static member functions. The specific steps include: 1. Use a private constructor and delete the copy constructor and assignment operator to prevent external direct instantiation. 2. Provide a global access point through the static method getInstance to ensure that only one instance is created. 3. For thread safety, double check lock mode can be used. 4. Use smart pointers such as std::shared_ptr to avoid memory leakage. 5. For high-performance requirements, static local variables can be implemented. It should be noted that singleton pattern can lead to abuse of global state, and it is recommended to use it with caution and consider alternatives.

Composer's Purpose: Managing Project Dependencies in PHP Composer's Purpose: Managing Project Dependencies in PHP Apr 30, 2025 am 12:01 AM

We need Composer because it can effectively manage dependencies of PHP projects and avoid the hassle of version conflicts and manual library management. Composer declares dependencies through composer.json and uses composer.lock to ensure the version consistency, simplifying the dependency management process and improving project stability and development efficiency.
