springboot統一處理Date參數

之前沒有統一處理,都是使用註解來處理date參數,如下

@DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss")
private Date createDate;
@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone="GMT+8")
public Date getCreateDate() {
	return createDate;
}
public void setCreateDate(Date createDate) {
	this.createDate = createDate;
}

統一處理

1.配置文件中加一下配置

spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8

2.添加日誌轉換類

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.core.convert.converter.Converter;

import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * 日期轉換類
 * 將標準日期、標準日期時間、時間戳轉換成Date類型
 */
/*@Deprecated*/
public class DateConverter implements Converter<String, Date> {

    private Logger logger = LoggerFactory.getLogger(DateConverter.class);

    private static final String dateFormat = "yyyy-MM-dd HH:mm:ss";
    private static final String shortDateFormat = "yyyy-MM-dd";
    private static final String timeStampFormat = "^\\d+$";

    @Override
    public Date convert(String value) {
        logger.info("轉換日期：" + value);

        if(value == null || value.trim().equals("") || value.equalsIgnoreCase("null")) {
            return null;
        }

        value = value.trim();

        try {
            if (value.contains("-")) {
                SimpleDateFormat formatter;
                if (value.contains(":")) {
                    formatter = new SimpleDateFormat(dateFormat);
                } else {
                    formatter = new SimpleDateFormat(shortDateFormat);
                }
                return formatter.parse(value);
            } else if (value.matches(timeStampFormat)) {
                Long lDate = new Long(value);
                return new Date(lDate);
            }
        } catch (Exception e) {
            throw new RuntimeException(String.format("parser %s to Date fail", value));
        }
        throw new RuntimeException(String.format("parser %s to Date fail", value));
    }
}

3.添加全局配置

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.propertyeditors.CustomDateEditor;
import org.springframework.core.convert.support.GenericConversionService;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.InitBinder;

import java.beans.PropertyEditorSupport;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;

@ControllerAdvice
public class ControllerHandler {

    private Logger logger = LoggerFactory.getLogger(ControllerHandler.class);

    @InitBinder
    public void initBinder(WebDataBinder binder) {
        // 方法1，註冊converter
        GenericConversionService genericConversionService = (GenericConversionService) binder.getConversionService();
        if (genericConversionService != null) {
            genericConversionService.addConverter(new DateConverter());
        }

        // 方法2，定義單格式的日期轉換，可以通過替換格式，定義多個dateEditor，代碼不夠簡潔
        DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        CustomDateEditor dateEditor = new CustomDateEditor(df, true);
        binder.registerCustomEditor(Date.class, dateEditor);


        // 方法3，同樣註冊converter
        binder.registerCustomEditor(Date.class, new PropertyEditorSupport() {
            @Override
            public void setAsText(String text) throws IllegalArgumentException {
                setValue(new DateConverter().convert(text));
            }
        });

    }
}
