手动加载上下文时无法自动装配字段 SessionFactory

Question

我有以下 applicationContext.xml:

<beans

    </beans>

我这样加载上下文：

ApplicationContext app = new ClassPathXmlApplicationContext("META-INF/applicationContext.xml");

但我看到以下错误：

Could not autowire field: private org.hibernate.SessionFactory com.terminal.dao.admin.impl.AdminRoleDaoImpl.sessionFactory
...
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

与这种情况不同，当我从 web.xml 加载上下文时它工作正常。

web.xml内容：

手动加载上下文时如何避免异常？

Answer 1

我想你忘了为 spring 设置配置文件。您的代码应如下所示：

System.setProperty("spring.profiles.active", "dev");
ApplicationContext app = new ClassPathXmlApplicationContext("META-INF/applicationContext.xml");
