1、创建java程序
create or replace and compile java source named sms as
import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
public class SMS
{
public static String entry(String id)
{
String datas = "d:\\oracleFile\\oracle.txt";
File data = new File(datas);
StringBuffer backup = null;
try {
StringBuffer content = new StringBuffer();
backup = new StringBuffer();
BufferedReader san = new BufferedReader(new FileReader(data));
String line = null;
while ((line = san.readLine()) != null) {
backup.append(line);
backup.append("/n");
}
content.append("15 ");
content.append(" oracle.txt");
content.append("/n");
content.append(id);
FileWriter writer = new FileWriter(data, false);
writer.write(content.toString());
writer.flush();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
try {
FileWriter writer = new FileWriter(data, false);
writer.write(backup.toString());
writer.flush();
} catch (Exception ex) {
ex.printStackTrace();
}
}
return id +="OK";
}
}
2、创建触发器
CREATE OR REPLACE TRIGGER LOADING_TRIGGER
AFTER INSERT OR UPDATE OR DELETE ON LOADCHANG_MAIN
FOR EACH ROW
DECLARE
OPT1 VARCHAR2(50);
BEGIN
IF INSERTING THEN
OPT1 := 'INSERT';
ELSIF UPDATING THEN
OPT1 := 'UPDATE';
ELSIF DELETING THEN
OPT1 := 'DELETE';
ELSE
OPT1 := 'UNKNOWN';
END IF;
DBMS_OUTPUT.PUT_LINE(TESTFUN(OPT1));
END LOADING_TRIGGER;
3、创建函数
CREATE OR REPLACE FUNCTION testFun(file in varchar2) return varchar2
AS LANGUAGE JAVA NAME 'SMS.entry(java.lang.String) return java.lang.String';
4、以管理员身份登陆数据库
由于要读写文件，需要对数据库用户进行文件读写授权，因此需要以管理员身份登陆数据库对用户授权
begin
dbms_java.grant_permission('GLMF','SYS:java.io.FilePermission','d:\oracleFile\*','read,write,delete');
end;
对GLMF用户授权可对D盘oracleFile文件夹下的所有文件及文件夹进行读写删除操作。
----------------------------------------8******************************************
加载java文件到数据库中，首先登陆到数据库服务器
1)加载jar到oracle数据库中
loadjava -r -f -verbose -resolve -user xmlbook/xmlbook xmlparserv2.jar
2）加载class到oracle数据库中
loadjava -r -f -user user_name/password[@URL] oracle/AAA/bbb/CCC.class
3）移除
dropjava -r -f -user user_name/password[@URL] [option_list] file_list
