配置分为2类

package naturallatex.config;

import javax.servlet.ServletContext;  
import javax.servlet.ServletException;  
import javax.servlet.ServletRegistration.Dynamic;  

import org.springframework.web.WebApplicationInitializer;  
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;  
import org.springframework.web.servlet.DispatcherServlet;  

public class WebAppInitializer implements WebApplicationInitializer {
    public void onStartup(ServletContext servletContext) throws ServletException {  
        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();  
        ctx.register(AppConfig.class);  
        ctx.setServletContext(servletContext);    
        Dynamic dynamic = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));  
        dynamic.addMapping("/");  
        dynamic.setLoadOnStartup(1);  
   }  
}

这是第二个

package naturallatex.config;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceBuilder;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

import javax.sql.DataSource;

@EnableAutoConfiguration
@Configuration
@ComponentScan("naturallatex")
@EnableWebMvc
@EnableJpaRepositories("naturallatex.dao")
public class AppConfig {

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    DataSource ds1() {
        return DataSourceBuilder.create().build();
    }

}

您能帮我吗，谢谢您
