在spring-mvc应用程序中未调用控制器

标签： java spring spring-mvc kotlin tomcat8

我有一个奇怪的流程，当我尝试启动spring-mvc项目时，所有内容都在构建并使用localhost:8080地址正确启动，但它仅显示Apache Tomcat主页并且每个请求都显示示例localhost:8080/login显示HTTP Status 404 – Not Found description:The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.奇怪的是，当我尝试在另一台计算机（Ubuntu）中运行相同项目时，它运行正常，登录页面正确显示并且每次请求工作良好。奇怪的是，这台意外的流程首次出现在这台机器上。

tomcat version is 8.5.24

这是我的dispatcher-servlet.xml 

 <!DOCTYPE web-app PUBLIC

 "http://java.sun.com/dtd/web-app_2_3.dtd" >

        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

这里是applicationContext.xml 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.awesome"/>

</beans>

这是我的配置类

@Configuration
@ComponentScan("com.awesome")
@EnableWebMvc
open class AppConfig : WebMvcConfigurerAdapter() {

@Bean
open fun viewResolver(): InternalResourceViewResolver {
    val internalResourceViewResolver = InternalResourceViewResolver()
    internalResourceViewResolver.setSuffix(".jsp")
    internalResourceViewResolver.setPrefix("/")
    return internalResourceViewResolver
}

override fun configureDefaultServletHandling(configurer: DefaultServletHandlerConfigurer?) {
    configurer?.enable()
    }
 }

这是控制器

@Controller
class HomeController {

@RequestMapping("/", method = [(RequestMethod.GET)])
fun displayLoginPage(): String {
    return "login"
}

@RequestMapping("/login", method = [(RequestMethod.POST)])
fun login(@RequestParam user_name:String, @RequestParam password: String, modelMap: ModelMap): String {
    return "main"
    }
}

这是启动日志

我已经修复了问题，我刚刚看到了我的工件，并且我用war更改了exploded工件，现在一切正常。

在c turbo编译器中首先编译零错误的代码，按f9可见，然后按ctrl + f9输出，然后按alt + f5，结果将在提示窗口中显示。
