错误：-> org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为'homeController'的bean时出错：通过字段'userTokenService'表示的不满足的依赖关系；嵌套的异常是org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为'userTokenService'的bean时出错：通过字段'repo'表示的不满足的依赖关系；嵌套的异常是org.springframework.beans.factory.BeanCreationException：创建名称为'passwordResetRepo'的bean时出错：调用init方法失败；嵌套的异常是java.lang.NoClassDefFoundError：antlr / RecognitionException

Answer 1

看看stacktrace。问题是：Spring IoC容器无法创建homeController bean；因为容器无法创建userTokenService bean；那是因为容器无法使用passwordResetRepo创建java.lang.NoClassDefFoundError bean。

在配置文件中添加以下内容即可解决您的问题：

<jpa:repositories base-package="com.book.entity.security.repo" />

在使用Spring Boot时，请在Accessing Data with JPA上查看本指南。

根据上述指南：

默认情况下，Spring Boot将启用JPA存储库支持并查看在包（及其子包）中，其中@SpringBootApplication是位于。如果您的配置具有JPA存储库界面包中的定义不可见，您可以指出使用@EnableJpaRepositories及其类型安全的备用软件包 basePackageClasses=MyRepository.class参数。

通过字段'userTokenService'表示的不满意依赖性
