springboot 备份oracle数据库

你可以使用以下步骤来备份Oracle数据库：

1. 在pom.xml文件中添加以下依赖项：

<dependency>
    <groupId>com.oracle.database.jdbc</groupId>
    <artifactId>ojdbc8</artifactId>
    <version>19.7.0.0</version>
</dependency>

2. 在application.properties文件中添加以下属性：

spring.datasource.url=jdbc:oracle:thin:@localhost:1521:ORCL
spring.datasource.username=YOUR_USERNAME
spring.datasource.password=YOUR_PASSWORD

3. 创建一个备份脚本，并使用Spring Boot的Scheduled注释将其定期运行。例如：

import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
public class BackupService {

    @Autowired
    private OracleService oracleService;

    @Value("${backup.path}")
    private String backupPath;

    @Scheduled(cron = "0 0 0 * * *") // 每天晚上12点执行备份
    public void backupDatabase() throws IOException {
        String fileName = new SimpleDateFormat("yyyyMMddHHmmss").format(new Date()) + ".dmp";
        String filePath = backupPath + "\\" + fileName;
        oracleService.backupDatabase(filePath);
    }
}

4. 在OracleService类中实现备份方法。例如：

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class OracleService {

    @Autowired
    private DataSource dataSource;

    public void backupDatabase(String filePath) throws IOException {
        List<String> commandList = new ArrayList<>();
        commandList.add("exp");
        commandList.add("USERID=" + dataSource.getUsername() + "/" + dataSource.getPassword());
        commandList.add("FILE=" + filePath);
        commandList.add("FULL=Y");
        commandList.add("LOG=" + filePath + ".log");

        ProcessBuilder processBuilder = new ProcessBuilder(commandList);
        Process process = processBuilder.start();

        try {
            int exitCode = process.waitFor();
            if (exitCode != 0) {
                throw new RuntimeException("Backup failed. Exit code: " + exitCode);
            }
        } catch (InterruptedException e) {
            throw new RuntimeException("Backup failed.", e);
        }
    }
}

你需要将YOUR_USERNAME和YOUR_PASSWORD替换为你的Oracle数据库用户名和密码，并将backup.path替换为备份文件的路径。请注意，此代码使用exp命令来备份数据库。如果你使用的是Oracle 12c或更高版本，请改用expdp命令。
