运行打包的jar时WARN 30704 --- [ main] ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.bean s.factory.BeanCreationException: Error creating bean with name 'mathController': Lookup method resolution failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [com.upc.jiye.controller.MathController] from ClassLoader [org.springframework.boot.loader.LaunchedURLClassLoader@6433a2]

这个错误通常表示在初始化应用程序上下文时遇到了问题,导致无法完成刷新尝试。具体地,它指出在创建名为 'mathController' 的 bean 时发生了一个错误,该错误是由于查找方法解析失败导致的。此外,还提到了一个 IllegalStateException 异常,该异常表示无法从给定的 ClassLoader 中内省 Class [com.upc.jiye.controller.MathController]。 这个问题通常是由于以下原因之一引起的: 1. 类路径中缺少必需的依赖项。请确保所有必需的库和依赖项已正确添加到类路径中。 2. 类或方法名称拼写错误。请确保 'mathController' 类和相关方法的名称拼写正确,并与实际代码一致。 3. 类或方法不存在。请确认 'com.upc.jiye.controller.MathController' 类和相关方法存在,并且可以从给定的 ClassLoader 中找到。 您可以尝试以下步骤来解决这个问题: 1. 检查应用程序的依赖项,并确保所有必需的库已正确添加。 2. 仔细检查 'mathController' 类和相关方法的名称拼写,确保它们与实际代码一致。 3. 确认 'com.upc.jiye.controller.MathController' 类和相关方法存在,并检查 ClassLoader 是否可以正确加载它们。 如果问题仍然存在,我建议您检查详细的异常堆栈跟踪以获取更多的信息,并尝试搜索类似问题的解决方案。

2023-05-10 22:43:47.650 WARN 2588 --- [ main] ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'productServiceImpl': Unsatisfied dependency expressed through field 'productDao'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'productDao': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class com.example.shopcommon.entity.Product

这个错误看起来是因为 Spring 依赖注入时无法满足依赖关系导致的。具体来说,`productServiceImpl` 的一个字段 `productDao` 没有被正确注入,导致 Spring 无法创建 `productServiceImpl` 实例。 进一步地,`productDao` 的初始化方法抛出了一个异常,原因是它试图管理一个不是 JPA 实体的类 `com.example.shopcommon.entity.Product`。 你可以检查一下 `productServiceImpl` 和 `productDao` 的定义和配置,确保它们之间的依赖关系正确。同时,也需要确认 `com.example.shopcommon.entity.Product` 是否确实是一个 JPA 实体,是否有正确的注解等。

这个错误提示是因为 Spring 容器在初始化时无法满足某些 bean 之间的依赖关系。具体来说,这里的错误是由于在 ProductController 中,ProductService 的依赖无法满足,导致无法创建 ProductController bean。而 ProductService 又依赖于 ProductDao,因此在创建 ProductService bean 时也遇到了错误。最后,错误的根源是在创建 ProductDao bean 时,因为它的实体类 com.example.shopcommon.entity.Product 不是一个被 Spring 托管的实体类,所以导致了初始化失败。 要解决这个错误,你需要检查以下几个方面: 1. 确认实体类 com.example.shopcommon.entity.Product 已经被 @Entity 注解修饰,并且被扫描到了。 2. 确认在创建 ProductDao 和 ProductService 时,依赖的实体类都已经被正确地扫描到了。 3. 如果实体类和 DAO 层都已经正确配置,那么你可以尝试使用 @ComponentScan 注解来让 Spring 自动扫描,以确保所有的类都被正确托管。
