Answer 1

将spring-web.jar添加到您的依赖项中：

org.springframework:spring-web:<your spring version>.RELEASE

Answer 2

当我尝试使用gradle使用spring boot构建项目时，我遇到了类似的问题。默认情况下，springboot项目是使用build.gradle文件中的此引用创建的：

dependencies {
implementation 'org.springframework.boot:spring-boot-starter'
testImplementation('org.springframework.boot:spring-boot-starter-test') {
    exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}}

更改了此引用：

org.springframework.boot:spring-boot-starter

为此：

org.springframework.boot:spring-boot-starter-web

对我有用。

如何解决错误“包org.springframework.web.bind.annotation不存在”
