1.创建日期转换类

package com.bms.config.time;

import com.bms.util.CommonUtils;
import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.databind.JsonDeserializer;
import org.apache.commons.lang3.StringUtils;
import org.apache.commons.lang3.time.DateUtils;

import java.io.IOException;
import java.text.ParseException;
import java.time.LocalDateTime;
import java.util.Date;

/**

 */
public class DateJacksonConverter extends JsonDeserializer<LocalDateTime> {
    private final static String[] PATTERN =
            new String[]{"yyyy-MM-dd", "yyyy-MM-dd HH:mm", "yyyy-MM-dd HH:mm:ss", "yyyy-MM-dd HH:mm:ss.S",
                    "yyyy.MM.dd", "yyyy.MM.dd HH:mm", "yyyy.MM.dd HH:mm:ss", "yyyy.MM.dd HH:mm:ss.S",
                    "yyyy/MM/dd", "yyyy/MM/dd HH:mm", "yyyy/MM/dd HH:mm:ss", "yyyy/MM/dd HH:mm:ss.S"};
    @Override
    public LocalDateTime deserialize(JsonParser p, DeserializationContext ctxt) throws IOException, JsonProcessingException {
        Date targetDate = null;
        String originDate = p.getText();
        if (!StringUtils.isBlank(originDate)) {
            try {
                long longDate = Long.parseLong(originDate.trim());
                targetDate = new Date(longDate);
            } catch (NumberFormatException e) {
                try {
                    targetDate = DateUtils.parseDate(originDate, PATTERN);
                } catch (ParseException e1) {
                    throw new IOException(String.format(
                            "'%s' can not convert to type 'java.util.Date',just support timestamp(type of long) and following date format(%s)",
                            originDate,
                            StringUtils.join(PATTERN, ",")));
                }
            }
        }
        return CommonUtils.date2LocalDateTime(targetDate);
    }

    @Override
    public Class<?> handledType() {
        return LocalDateTime.class;
    }
}

2.配置全局的日期类型转换器

package com.bms.config.time;

import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;

/**
 * 全局的日期类型转换器
 * @author 咸鱼
 * @date 2019-07-12 21:24
 */
@Configuration
public class ConverterConfig {
    @Bean
    public DateJacksonConverter dateJacksonConverter() {
        return new DateJacksonConverter();
    }
    @Bean
    public Jackson2ObjectMapperFactoryBean jackson2ObjectMapperFactoryBean(
            @Autowired DateJacksonConverter dateJacksonConverter) {
        Jackson2ObjectMapperFactoryBean jackson2ObjectMapperFactoryBean = new Jackson2ObjectMapperFactoryBean();
        jackson2ObjectMapperFactoryBean.setDeserializers(dateJacksonConverter);
        return jackson2ObjectMapperFactoryBean;
    }
    @Bean
    public MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter(
            @Autowired ObjectMapper objectMapper) {
        MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();
        mappingJackson2HttpMessageConverter.setObjectMapper(objectMapper);
        return mappingJackson2HttpMessageConverter;
    }
}
