报错原因：别问我我现在也不知道呢
解决方法：用Tomcat8完美解决问题，哈哈
错误五：springboot 默认扫描的路径，是该工程application启动类所在包以及所有子包下的所有文件。
所以说你在其他定义的类他不会加载进容器；哎呀挖槽又踩了一个坑，
就像这里：根本没有将HelloController扫描进去：..................................
当然你也可以指定要扫描特定的包：
package org.framework.demo.section1; import org.springframework.boot.Banner; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.context.properties.EnableConfigurationProperties; import org.springframework.boot.web.servlet.ServletComponentScan; import org.springframework.context.annotation.ComponentScan; /** * 在SpringBoot中简单使用Servlet * 通过注解注册Servlet * @author chengxi */ @SpringBootApplication //改变自动扫描的包 @ComponentScan(basePackages = {"org.test1", "org.test2"}) public class ServletApp2 { public static void main(String[] args){ //关闭banner的输出 SpringApplication app = new SpringApplication(ServletApp2.class); // app.setBannerMode(Banner.Mode.OFF); app.run(args); } }
错误六：
背景：使用
Error resolving template [add], template might not exist or might not be accessible by any of the configured Template Resolvers
解决方法：
检查配置文件：
thymeleaf:
prefix: classpath:/templates/
controller要ResponseBody
合群是堕落的开始 优秀的开始是孤行
