javax.servlet-api报错问题

报错：NoClassDefFoundError: javax/servlet/http/HttpServletResponse
服务原有依赖

		<dependency>
		    <groupId>javax.servlet</groupId>
		    <artifactId>javax.servlet-api</artifactId>
		    <scope>provided</scope>
		</dependency>

新加依赖后解决

		<dependency>
			<groupId>org.apache.tomcat.embed</groupId>
			<artifactId>tomcat-embed-websocket</artifactId>
			<version>9.0.44</version>
		</dependency>

		<dependency>
			 <groupId>org.springframework.boot</groupId>
			 <artifactId>spring-boot-starter-thymeleaf</artifactId>
		</dependency>
