[Solved] SpringBoot Create Project and Failed to Access localhost:8080 Error

1. Error prompt

java.lang.NoSuchMethodError: javax.servlet.http.HttpServletRequest.getHttpServletMapping()Ljavax/servlet/http/HttpServletMapping;

 

2. The reason is that the Tomcat version is incompatible with springboot

I use

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.10.RELEASE</version>
</parent>

2. The solution is to modify the below codes in pom.xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.10.RELEASE</version>
</parent>

to:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.5.RELEASE</version>
</parent>
