在我的项目中,我有三个模型文件--用户、约会和通知。有三个存储库接口,每个接口实现CrudRepository。服务类和控制器类也存在。在执行项目时,我得到了两个错误:1。在类路径上未检测到spring Webinitializer。2.创建bean时出现异常。下面是堆栈跟踪:

Spring Version-4.3.8。Release和Spring data jpa Version-1.0.2。Release组合对我来说很有效。
如果是版本问题,那么可能是您可以尝试这种组合。
在使用Spring Data JPA和Hibernate的web应用程序中,我们利用web分页功能在各种实体列表中提供分页和排序功能。 这允许在呈现的html中将实体属性定义为特殊的排序请求参数,其中值实际上与要排序的实体中的属性匹配。 这将生成一个结果URL,例如: 问题是,用户可能会修改URL以使用无效的属性,这些属性引用不存在的列/属性名称,或者更糟的是,使用无效的JPA查询字符导致无效语法
我正在尝试使用以下命令构建我的Spring启动项目: 但它不断抛出这个错误: 我的项目使用Java版本11,IntelliJ Java版本也设置为11。 这是我到目前为止在IntelliJ上完成的Java版本设置: 当我跑完这一切后 我想我已经做了所有可能的事情。还有其他我可以尝试的设置吗??
问题内容: 我见过类似的问题,但尚未找到答案。 使用Maven编译,我得到: 这是pom.xml: Javac版本: Java版本: 知道会是什么吗? 问题答案: 您需要将JAVA_HOME设置为jdk7主目录,例如在Microsoft Windows上: “ C:\ Program Files \ Java \ jdk1.7.0_40” 或在OS X上: /图书馆/Java/JavaVirtua
我与Gradle在IntelliJ中创建了一个新的Java项目,该项目使用Java 17。运行我的应用程序时出现错误。 我的设置 我已经通过安装了,并将其设置为我的。 已设置为。 在
使用maven compile,我得到: 下面是pom.xml: Javac版本: 知道可能是什么吗?
