Java：即使模块信息打开了必要的包，springrframework.beans 也无法访问

Question

我有一个包 warehouse.controller，我正在尝试 import org.springframework.beans.factory.annotation.Autowired;，但我收到一个错误： The import org.springframework.beans.factory.annotation.Autowired cannot be resolvedJava

到目前为止，我的module-info.java 看起来像这样：

module warehouse {
    requires javafx.controls;
    requires javafx.fxml;
    requires spring.data.jpa;
    requires java.persistence;
    requires java.base;
    requires java.sql;

    requires spring.core;
    requires spring.boot;
    requires spring.data.commons;
    requires spring.context;
    requires spring.beans;
    requires java.transaction;

    opens warehouse.controller to javafx.fxml, spring.beans, spring.context;
    opens warehouse;

    exports warehouse;
    exports warehouse.controller;
}

而我的pom.xml 包含这些依赖项：

您好，您的 pom.xml 中缺少 spring boot starter web，请将以下依赖项添加到您的项目中

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