Note that only Django core commands are listed as settings are not properly configured (error: The TEMPLATE_DIRS setting must be a list or a tuple. Please fix your settings.).

参考技术A 启动要带参数的，

spring mvc注入service报错是啥原因？

部分代码如下：

报错:org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private myforum.service.UserTest myforum.controller.UserController.userTest; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [myforum.service.UserTest] 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)
配置如下：web.xmlcontextConfigLocationclasspath:spring.xml,classpath:spring-hibernate.xmlspring mvc servletspringMvcorg.springframework.web.servlet.DispatcherServletspring mvc 配置文件contextConfigLocationclasspath:spring-mvc.xml1    springMvc*.action  spring.xmlspring-mvc.xml
需要的都提供了  应该没错，就是注入错误。求牛人解答

从controller到service到dao全部检查一遍；

或者全部粘贴出来，才能看到问题。
