解决方案:
在启动类添加
@EnableScheduling
@SpringBootApplication
@MapperScan("com.sxd.swapping.dao.mybatis")
public class SwappingApplication { public static void main(String[] args) {
/**
* Springboot整合Elasticsearch 在项目启动前设置一下的属性,防止报错
* 解决netty冲突后初始化client时还会抛出异常
* java.lang.IllegalStateException: availableProcessors is already set to [4], rejecting [4]
*/
System.setProperty("es.set.netty.runtime.available.processors", "false");
SpringApplication.run(SwappingApplication.class, args);
}
}
