Java 批注spring mvc-未找到映射

我是SpringMVC的新手，希望为我的应用程序进行注释配置。没有web.xml或类似的东西。我已经编写了两个我想访问的jsp页面，两个控制器类和一个应用程序类，其main方法如下所示：

import javax.servlet.ServletContext;
import javax.servlet.ServletRegistration;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.servlet.DispatcherServlet;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration
@ComponentScan
@EnableAutoConfiguration
@EnableWebMvc
public class Application extends SpringBootServletInitializer implements WebApplicationInitializer{

    static final Logger logger = LoggerFactory.getLogger(Application.class);

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

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

控制器示例：

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class IndexController {

    static final Logger logger = LoggerFactory.getLogger(IndexController.class);

    @RequestMapping(value = {"/index","/"})
    @ResponseBody
    public ModelAndView index()
    {
        return new ModelAndView("index");
    }
}

最后是我编辑的pom.xml

谁能在这个问题上提供帮助？我怀疑我应该用DispatcherServlet注入一个bean，但我真的不知道该如何使用它以及如何正确设置它

在webMvcConfig.java上添加以下配置

@ComponentScan({ "com.your.controller"})

---

它可能是两个不同包中的Application.java和IndexController.java。那么你必须这样提

@ComponentScan（base=“your packge”）

---

完整示例：-

您的

@Controller

和

@Configuration

类是否在同一个包中？首先，您的pom有缺陷，您的spring版本有问题。只需使用提供的弹簧靴即可。删除

spring.version

并删除

spring核心依赖项。同时删除
@EnableWebMvc
注释和
实现不需要的WebApplicationInitializer
。确保您的
应用程序
类与控制器位于同一个包中，或者位于控制器上方的包中。我倾向于将其放在顶级包中，以便
@ComponentScan
涵盖所有内容。谢谢，将所有内容移动到一个包的提示修复了我的错误。
@ComponentScan({ "com.your.controller"})
