#ssh报错

本文解析了Hibernate在管理bean类时遇到的构造异常问题，详细分析了com.integration.entity.Info类的构造函数缺失导致的问题，并提供了有效的解决方案。

一、有入下异常

1.报错原因

没有实体的默认构造函数:com . integration . entity . Info；嵌套异常是org . hibernate . instantionException:没有实体的默认构造函数:com.integration.entity.Info

很明显，由hibernate所管理的bean类Info并未成功构造，问题出现在Info类上。下图为报错时所写Info类，很明显跟我们学MVC时常写的bean类格式并无差别，而就是种方式造成的错误。

2.参考解决方法 

将bean修改为如下图后，异常解决，读者可仔细对比其区别

最近用spring cloud搭建项目时出现了一个奇怪的问题，直接上异常和我的解决方法。 在网上找了一通，无非以下三种说法： 1.spring的注解配置错误，如@Service，@Entity,@Table等注解写错或者引错包，比如Servicre的正确包应该是 import org.springframework.stereotype.Service; 然而本人不是这个错误引起； 2.POJO或者Entity中的setter和getter写错，比如大小写字母，返回类型等，或者是与表中的字段不一致
