springBoot事務失效導致批量插入性能巨幅降低

    @Override
    public void savePatientAndSeekMedical(){
        long start = System.currentTimeMillis();
//        ((PatientService) AopContext.currentProxy()).saveBatch(patients, 1000);
//        saveBatch(patients, 1000);
        SpringUtil.getBean(this.getClass()).saveBatch(patients, 1000);
//        patientMapper.saveBatchBySql(patients);
//        seekMedicalService.saveBatch(seekMedicals, 1000);
        log.warn("保存" + patients.size() + "條患者數據，用時：" + (System.currentTimeMillis() - start) + "ms");
        patients.clear();
        seekMedicals.clear();
    }

這段代碼里面使用了三種方式保存患者數據

第一種 ((PatientService) AopContext.currentProxy()).saveBatch(patients, 1000); 方式在這里會拋出Cannot find current proxy: Set 'exposeProxy' property on Advised to 'true' to make it available異常，猜測原因是saveBatch是mybatisPlus的方法，普通情況如果需要在在該方法上做切面可以用該方式

 

第二種 saveBatch(patients, 1000); 會導致性能巨慢 導入2w調數據需要900秒左右

 

第三種 SpringUtil.getBean(this.getClass()).saveBatch(patients, 1000); 可以保證事務並且性能非常好（2w條數據大概15秒左右）

 

貼上SpringUtil代碼

package cn.rivamed.fhvc.util;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.core.env.Environment;
import org.springframework.stereotype.Component;

@Component
public class SpringUtil implements ApplicationContextAware {

    private static ApplicationContext applicationContext = null;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        SpringUtil.applicationContext = applicationContext;
    }

    public static <T> T getBean(Class<T> cla) {
        return applicationContext.getBean(cla);
    }

    public static <T> T getBean(String name, Class<T> cal) {
        return applicationContext.getBean(name, cal);
    }

    public static Object getBean(String name){
        return applicationContext.getBean(name);
    }

    public static String getProperty(String key) {
        return applicationContext.getBean(Environment.class).getProperty(key);
    }
}
