Question

我已阅读TCP-Server-Client并尝试运行我的示例，但我收到以下错误：

@Controller
public class HelloWorldController {

    @Autowired
    SimpleGateway gw;

    @RequestMapping(value = { "/", "/home", "/frontend" }, method = RequestMethod.GET)
    public String homePage(Locale locale, ModelMap model) {

        gw.send("test");

        return "frontend";
    }

}

我的控制器：

</beans>

我的xml配置：

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.example.myapp")
public class HelloWorldConfiguration extends WebMvcConfigurerAdapter {
   ...
}

我还没想通，如果需要任何其他附加配置文件。

编辑1：我的配置文件：

og:url

Answer 1

您需要导入XML配置。

将@ImportResource("foo.xml")添加到您的@Configuration课程。

或者，使用@Bean而不是XML添加Spring Integration配置。

Answer 2

您好像没有指定组件扫描位置。尝试将以下标记添加到XML。

<context:component-scan base-package="<package-to-scan-under-spring-servlet>" />

Spring Integration无法自动装配字段
