出现意外错误（type = Not Found，status = 404）。没有可用消息

Question

我收到以下错误：

出现意外错误（type = Not Found，status = 404）。没有可用的消息

使用Spring Boot + Thymeleaf

代码：

申请类：

package com.mycom.extract;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication(scanBasePackages = "com.mycom.extract")
public class MyAppExtractionWebApplication  extends SpringBootServletInitializer {

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




	
	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
		return application.sources(MyAppExtractionWebApplication.class);
	}
}

SecurityConfig

WebMvcConfiguration

package com.mycom.extract.config;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@EnableAutoConfiguration
@Configuration
@ComponentScan(basePackages = { "com.mycom.extract" })
public class MyAppConfiguration extends WebMvcConfigurerAdapter{

	@Override
	public void addViewControllers(ViewControllerRegistry registry) {
		registry.addRedirectViewController("/", "/login");
		registry.addViewController("/login").setViewName("index");
		registry.addViewController("/home").setViewName("home");
	}
}

在Stackoverflow中引用所有相同类型的帖子可以为我自己找到解决方案。

请建议。

As I am setting up login, and authentication is handled at security config side, so once it is successful it shows home page. Hence no controller mentioned.
