java.lang.ClassCastException异常

Question

java.lang.ClassCastException: com.ysb.system.project.monitor.online.domain.OnlineSession cannot be cast to com.ysb.system.project.monitor.online.domain.OnlineSession

请问各位大神遇到过这样的强转问题吗？

Answer 1

spring的devtools引起的，你把下面的依赖去掉应该就可以了

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-devtools</artifactId>

    <scope>runtime</scope>

</dependency>
