即使在 POM 中定义了包 org.springframework.web.bind.annotation 也不存在 [英] package org.springframework.web.bind.annotation does not exist even though it's defined in POM

问题描述

所以我有这个代码

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

而且我的 POM 文件中已经包含以下内容

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>

然而，当我构建它时，它最终抱怨包 org.springframework.web.bind.annotation 不存在

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

为什么?我已经添加了 spring web 作为依赖项.我做错了什么?

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

推荐答案

我遇到了类似的问题，我通过进入我的 pom.xml 文件并更改了 spring boot 依赖项的 artifactID 来解决它:

I had a similar issue, I fixed it by going into my pom.xml file and changing the artifactID for the spring boot dependency from:

<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>
