java - 无法将 JavaTimeModule 导入 Spring Boot 配置类

Question

当我尝试导入import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;

这是我的类(class):

package com.linkedin.learning.linkedinfullstackappangularspringboot.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.ObjectWriter;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;


@Configuration
public class ApiConfig {

@Bean
public ObjectMapper objectMapper() {
    ObjectMapper objectMapper = new ObjectMapper();
    objectMapper.registerModule(new JavaTimeModule());

    return new ObjectMapper();
}

@Bean
public ObjectWriter objectWriter(ObjectMapper objectMapper) {
    return objectMapper.writerWithDefaultPrettyPrinter();
}

它不导入。在我的 build.gradle 文件中，我有以下内容:

// https://mvnrepository.com/artifact/com.fasterxml.jackson.datatype/jackson-datatype-jsr310 compile group: 'com.fasterxml.jackson.datatype', name: 'jackson-datatype-jsr310', version: '2.9.2'

项目成功构建，但我仍然无法将其导入到我的类(class)中。我能做什么？

尝试更新一次 Gradle 项目，这应该会再次下载依赖项。 否则，请单独下载 jar 并将其作为依赖项手动包含在您的项目中。
