Initialization of bean failed; nested exception is org.springframework.beans.InvalidPropertyException: Invalid property 'dataSource' of bean class [com.liuyang.jdbc.PersonDao]: No property 'dataSource

这个错误是说我的启动失败了.这类问题要从配置文件中开始找原因,我用的是spring框架,所以我从application.中找的原因 然后对比路径,对比文件的命名和id,都没有问题,为什么会在启动的时候找不到dataSource,我想到应该是少包,但是,找寻发现包也没有问题. 最后发现是这里错了 这里是重点:::!!!!! 我的getter和setter的方法中设置的dateSource,而配置文件想要注入的是dataSource,两个名称不一致,难怪机器找不到我的文件的class,更改 <bea…

org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [java.util.List]: Specified class

错误:org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [java.util.List]: Specified class 这是我使用Spring MVC的时候出的错误,在前台将多个信息的id封装成一个集合后传递到控制层,向让这些id自动映射到控制层方法的参数上 我这个参数是一个List类型,因为Spring MVC是不能这样直接映射到集合类型的参数的,我们需要将这个集合类…

问题: Springboot 启动时出错,报没法创建bean的错误,看到nested最后是关于mongoTemplate的错误. 过程: 看网上大多说的是修改mongoTemplate的配置,但是springBoot自动注入我都没有配置,还有的说是注解没有写比如@service @autowired等,检查了一下都对啊. 解决方法 我之前运行的时候都挺好的啊,找了半天,才发现之前更新了一下  spring-data-mongodb依赖  从2.1.6到2.2.0 ,应该是兼容的问题,回退到2.1…
