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: 9321
spring:
datasource:
dynamic:
primary: master #设置默认的数据源或者数据源组，默认值即为master
strict: 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-8
username: SYSDBA
password: SYSDBA
driver-class-name: dm.jdbc.driver.DmDriver
db2 : #子数据源
url: jdbc:oracle:thin:@localhost:1521:ORCL?useUnicode=true&characterEncoding=ZHS16GBK
username: avic
password: avic
driver-class-name: oracle.jdbc.driver.OracleDriver
mybatis:
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: debug
file:
name: ./logs/my.log
pattern:
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 {
@Autowired
private IOperationService operationService;
@Autowired
private 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);
}
}
6.打包+运行指令
因项目需要 package 打包成了 war 包
