news 2025/6/29 19:13:28

因项目要求,需要定时从达梦数据库中取数据,并插入或更新到ORACLE数据库中

2.yml 文件

server:port: 9321spring:datasource:dynamic:primary: master #设置默认的数据源或者数据源组，默认值即为masterstrict: true  #设置严格模式，默认false不启动，启动后在未匹配到指定数据源时，会抛出异常，不启动则使用默认数据源datasource:master: #主数据源url: jdbc:dm://127.0.0.1:5236/test?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=UTF-8username: SYSDBApassword: SYSDBAdriver-class-name: dm.jdbc.driver.DmDriverdb2 : #子数据源url: jdbc:oracle:thin:@localhost:1521:ORCL?useUnicode=true&characterEncoding=ZHS16GBKusername: avicpassword: avicdriver-class-name: oracle.jdbc.driver.OracleDrivermybatis:mapper-locations: classpath:/mapper/*.xml # 配置MyBatis-Plus扫描Mapper文件的位置type-aliases-package: com.example.pro.pojo # 创建别名的类所在的包logging:level:com:example:pro: debugfile:name: ./logs/my.logpattern:console: "%d{yyyy/MM/dd-HH:mm:ss} [%thread] %-5level %logger- %msg%n"file: "%d{yyyy/MM/dd-HH:mm} [%thread] %-5level %logger- %msg%n"

3.mapper

主数据源是达梦的,达梦mapper调用不需要额外的配置,正常使用即可

从数据源是oracle的,需要额外进行配置 @DS(value = "从数据源")

package com.example.pro.mapper;import com.baomidou.dynamic.datasource.annotation.DS;
import com.example.pro.pojo.AvicUser;
import org.apache.ibatis.annotations.Mapper;import java.util.ArrayList;
import java.util.List;/*** OracleMapper*///@Repository
@Mapper
public interface OracleMapper {@DS(value = "db2")List<AvicUser> getList();@DS(value = "db2")int insetList(ArrayList<AvicUser> avicList);@DS(value = "db2")void insertObj(AvicUser avicUser);
}

4.定时任务

package com.example.pro.timer;import com.example.pro.service.IOperationService;
import com.example.pro.service.IOracleService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;/*** 定时任务 , 每天 晚上 11点 执行*/@Slf4j
@Component
public class Schedule {@Autowiredprivate IOperationService operationService;@Autowiredprivate IOracleService oracleService;public Schedule() {log.debug("创建计划任务类对象：Schedule");}/*@Scheduled(cron = "0 0 23 * * ? ")每天晚上11点开始执行任务*///@Scheduled(fixedRate = 1 * 60 * 1000)@Scheduled(cron = "0/300 * * * * ?")   //30秒执行一次public  void timedTask() {log.debug("开始执行处理定时的计划任务……");operationService.angelhood();//oracleService.getDmlist();//oracleService.getOraclelist();log.debug("处理定时的计划任务执行完成！");}
}

5.启动类

package com.example.pro;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.scheduling.annotation.EnableScheduling;@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})//多数据源时是使用
@EnableAspectJAutoProxy //开启Spring Boot对AOP的支持
@MapperScan("com.example.pro.mapper")//包扫描
@EnableScheduling//开启定时
public class ProApplication {public static void main(String[] args) {SpringApplication.run(ProApplication.class, args);}}
