Springboot全局日期格式化

package com.common.config;

import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class JsonConfig {
    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jsonCustomizer() {
        return builder -> {
            builder.simpleDateFormat("yyyy-MM-dd HH:mm:ss");
        };
    }
}

  【替代】实体类日期格式化：

    /** 创建时间 */
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private Date createTime;
