springboot项目访问html页面

1. springboot项目访问html页面

记录一下在springboot项目中如何访问html页面的配置，免得每次需要的时候又得到处去找，找了又忘

2. 创建一个基于springboot框架的web应用，不需要其它依赖

            </plugin>
        </plugins>
    </build>

</project>

3. application.properties配置

# 配置静态资源地址，默认地址："classpath:/META-INF/resources/", "classpath:/resources/", "classpath:/static/", "classpath:/public/
spring.resources.static-locations=classpath:/templates/
# 如果将html页面直接放在templates目录下，可能省略下面这行配置
spring.mvc.view.prefix=views
# 必须的，不然报错
spring.mvc.view.suffix=.html
server.port=8089

4. 配置文件

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

/**
 * @Author ZhengQinfeng
 * @Date 2020/11/12 22:04
 * @dec
 */
@Configuration
public class WebConfig implements WebMvcConfigurer {
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
//        spring.mvc.view.prefix + /index + spring.mvc.view.suffix 构成完整的请求地址
//        访问项目根目录即是访问 /views/index.html页面
        registry.addViewController("/").setViewName("/index");
    }
}

5. 启动springboot项目即可
