package org.springframework.web.bind.annotation does not exist even though it's defined in POM

Question

So I have this code

import org.springframework.web.bind.annotation.GetMapping;

And I already have the following in my POM file

<packaging>war</packaging>
    <properties>
        <spring.version>4.3.0.RELEASE</spring.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>
    </dependencies>

Yet when I built it ends up complaining package org.springframework.web.bind.annotation does not exist

Why? I already added spring web as a dependency. What am I doing wrong?

Answer 1

我有一个类似的问题，我通过进入我的 pom.xml 文件并从以下位置更改 spring boot 依赖项的 artifactID 来修复它：

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

到

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

Answer 2

Run the following command

mvn clean install

如果您正在使用像intelliJ idea或Eclipse这样的IDE，请确保重新导入项目。这是一个如何在Eclipse中刷新Maven依赖关系的答案
