通过数组方式向Oracle大批量插入数据（10万条11秒）

1.创建数据库Person

CREATE TABLE Person( 
id number,
name nvarchar2(200) ,
age number ,
sex nvarchar2(200) ,
password nvarchar2(200)
)

2.在数据库建立一个type,对应JAVA端要传入的对象结构:

   CREATE OR REPLACE TYPE BUT_UKBNOV_CTC_ORDER_REC1 AS OBJECT (
  id number,
   name nvarchar2(200) ,
   age number ,
   sex  nvarchar2(200) ,
   password  nvarchar2(200)

)

　3.为了数组传输,建立一个数组类型的type:

CREATE OR REPLACE TYPE BUT_UKBNOV_CTC_ORDER_TAB AS TABLE OF BUT_UKBNOV_CTC_ORDER_REC1

4,建立存储过程做插入工作:

   create or replace procedure bulkInsertCTDORDER(i_orders IN BUT_UKBNOV_CTC_ORDER_TAB)
as
ctcOrder BUT_UKBNOV_CTC_ORDER_REC1;
begin
    FOR idx IN 1..i_orders.COUNT   LOOP
        ctcOrder:=i_orders(idx);
        INSERT INTO person
          (id,
           name,
           age,
           sex,
           password
           )
        VALUES
          (ctcOrder.id,
           ctcOrder.name,
            ctcOrder.age,
             ctcOrder.sex,
              ctcOrder.password
           );
    end loop;
    exception when others then
    raise;
end;

5,建立JAVA端java bean对象

package me.person;

public class Person {
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
private int id;
private String name;
private int age;
private String sex;
private String password;
}

6.在JAVA端访问存储过程插入数据,需要做JAVA数据类型和存储过程类型type的映射,下面的StructDescriptor是mapping Oracle端AS OBJECT类型,
tabDesc 是mapping Oracle端数组 AS TABLE OF类型的.

package me.arrayinsertbatch;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.util.ArrayList;
import java.util.List;

import org.springframework.stereotype.Service;

import me.person.Person;
import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;
import oracle.sql.STRUCT;
import oracle.sql.StructDescriptor;
@Service("insertbatchservive")
public class ArraybatchInsertFromExcel {
     public void insertbatchfromexcel() throws Exception//10万条11秒
     {
         double begin = System.currentTimeMillis();
         Connection con = null;  
         CallableStatement cstmt = null;       
         try {                 
             con = ArrayInsertBatch.getConn();  
           List<Person> orderList = new ArrayList<Person>();  
            
             for(int i=0;i<100000;i++){ 
                 Person per=new Person();
                 per.setId(i);
                 per.setName("InsertName"+i);
                    per.setPassword("insertpassword"+i);
                    per.setSex("男");
                    per.setAge(i);
                 orderList.add(per);  
             }   
             //JSONArray json=JSONArray.fromObject(orderList);
             //System.out.println(json.toString());
             StructDescriptor recDesc = StructDescriptor.createDescriptor("BUT_UKBNOV_CTC_ORDER_REC1",  con);  
             ArrayList<STRUCT> pstruct = new ArrayList<STRUCT>();  
             for (Person ord:orderList) {                  
                 Object[] record = new Object[5];  
                 record[0] = ord.getId();  
                 record[1] = ord.getName();  
                 record[2] = ord.getAge();  
                 record[3] = ord.getSex();  
                 record[4] = ord.getPassword(); 
               // JSONArray json1=JSONArray.fromObject(record);
            //  System.out.println(json1.toString());
                     //System.out.println(record[4].toString());
                 STRUCT item = new STRUCT(recDesc, con, record);                  
                 pstruct.add(item);  
             }  
             //JSONArray json2=JSONArray.fromObject(pstruct);
            // System.out.println(json2.toString());
             ArrayDescriptor tabDesc = ArrayDescriptor.createDescriptor("BUT_UKBNOV_CTC_ORDER_TAB", con);              
             ARRAY vArray = new ARRAY(tabDesc, con, pstruct.toArray()); 
             
             //JSONArray json=JSONArray.fromObject(pstruct.toArray());
            // System.out.println(json.toString());
             cstmt = con.prepareCall("{call bulkInsertCTDORDER(?)}");       
             cstmt.setArray(1, vArray); 
             //cstmt.setString(2, SYSJ);
            //    cstmt.setString(4, QYSJ);
             cstmt.execute();  
             con.commit();  
              double time = (System.currentTimeMillis() - begin) / 1000;
              System.out.println("插入共花费时间" + time + "s");
     
     
     }
         catch(Exception ex)
         {
             
             throw ex;
         }
    }
}

上面的示例在插入10万条记录只用了11秒
