标签： spring-boot

我刚才是Spring Boot的新手，我尝试使用最简单的Spring启动Web应用程序

  

“Hello World”

jsp页面。

但我得到的例外情况如下

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mvcValidator' defined in class org.springframework.web.servlet.config.annotation.DelegatingWebMvcConfiguration: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory

我的简单java文件位于

之下 
package com.config;

@SpringBootApplication(scanBasePackages = {"com.config"})   
public class EaSiSamApplication extends SpringBootServletInitializer{

    public static void main(String[] args) {
        SpringApplication.run(EaSiSamApplication.class, args);
    }

    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(EaSiSamApplication.class);
    }
}

我的控制器如下     包com.config.controller 

@Controller
public class Login {

    @RequestMapping("/")
    public String login() {
        return "login";
    }
}

我保留了我的

  

的login.jsp

在src / main / resource-＆gt; templates-＆gt; login.jsp

中

在上面运行代码时，我正在 404

请帮我摆脱这个问题。我在网上得到了很多有用的教程，但我很想知道我的错。
