Question

我正在尝试为spring / hibernate应用程序设置一个基本模板。我之前从未这样做过，所以我真的不知道问题是什么。这是错误输出和代码的链接。我认为它试图自动配置而不是读取我的spring.xml文件。

Answer 1

您应该将以下类注释添加到Application.java：

@ImportResource(value = {"/spring.xml"})
@ComponentScan
@EnableAutoConfiguration
public class Application {
     ...
}

@ComponentScan仅自动检测Spring Components构造型注释。对于xml，您必须添加@ImportResource。

此外：

ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
context.close();

上面的那些行是多余的：Application.class，args）;`足以让spring boot启动你的应用程序。

或者，如果您不想使用弹簧靴，只需注释上面的一行（即SpringApplication.run(...)）
