Java Spring Boot找不到控制器'；s映射

数据控制器

package go.controller;
@Controller
public class DataController {

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String start(){
        return "index";
    }

package go.config;
public class WebMvcConfig extends WebMvcConfigurerAdapter {
    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer){
        configurer.enable();
    }
    @Bean
    public InternalResourceViewResolver viewResolver(){
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("WEB-INF/pages");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }

}

WebMvcConfig

package go.controller;
@Controller
public class DataController {

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String start(){
        return "index";
    }

package go.config;
public class WebMvcConfig extends WebMvcConfigurerAdapter {
    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer){
        configurer.enable();
    }
    @Bean
    public InternalResourceViewResolver viewResolver(){
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("WEB-INF/pages");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }

}

静态资源配置

package go.config;
public class StaticResourceConfiguration extends WebMvcConfigurerAdapter {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**").addResourceLocations("/**");
    }
}

我在

src/main/webapp/WEB-INF/pages/

为什么Spring Boot显示未找到

404

？

资源位置应该是一个目录，例如“/”，“classpath:/META-INF/public web resources/”您的主类在哪个包中？您是否看到启动期间记录的DataController映射？另外，当您使用SpringBoot时，您的配置比需要的要详细得多。看一看。
