我在运行spring boot项目时遇到了一个问题:
我使用vaadin作为ui,maven作为dependecies。这个数据库是mysql数据库,我已经按照(https://spring.io/guides/gs/accessing-data-mysql/)非常接近。
说明:
org.springframework.boot.autoconfigure.orm.jpa.hibernatejbaaautoconfiguration中构造函数的参数0需要找不到类型为“javax.sql.datasource”的bean。-未加载bean方法“datasource”,因为@conditionalonproperty(spring.datasource.jndi name)未找到属性“jndi name”-未加载bean方法“datasource”,因为@conditionalonbean(类型:org.springframework.boot.jta.xadatasourcewrapper;searchstrategy:all)未找到任何bean
行动:
考虑重新访问上述条件或在配置中定义“javax.sql.datasource”类型的bean。

尝试在traderepo上方添加@repository注解,并将其重命名为traderepository
