需要修改依赖
<dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</
artifactId> <version>${servlet-api.version}</version><!-- 版本自己定义 --> <scope>
provided</scope><!-- 必须要有 --> </dependency>
<> <>启动成功但是404

遇到404 肯定是因为路径错误 
仔细检查你的默认html或者jsp等等是否与web.xml中配置的一致
<welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file
>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>
default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-
file>default.jsp</welcome-file> </welcome-file-list>
