    已采纳

    maven仓库里面没有找到你引入的jar包，你打开你的maven仓库看看

    在

    spring-boot-starter-web依赖中就好了：

实例：
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <!--排除jackson-->
        <exclusion>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
        </exclusion>
    </exclusions>
</dependency>

    我是在pom里添加了这个，所有应该直接下载到项目里的。发现有那个jar，但是项目没有刷新过来


    但是我解决了我的那个问题，项目强制刷新一下后，就解决了。
