1、注解处理

之前没有统一处理,都是使用注解来处理date参数,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;
}

	@ApiModelProperty(value="时间窗开始时间",name="startTime", example = "2018-11-22 23:12:23")
	@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
	@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
	private Date startTime;

2、统一处理

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）、添加日志转换类

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.core.convert.converter.Converter;
 
import java.text.SimpleDateFormat;
import java.util.Date;
 
/**
 * 日期转换类
 * 将标准日期、标准日期时间、时间戳转换成Date类型
 */
/*@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("转换日期：" + 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，注册converter
        GenericConversionService genericConversionService = (GenericConversionService) binder.getConversionService();
        if (genericConversionService != null) {
            genericConversionService.addConverter(new DateConverter());
        }
 
        // 方法2，定义单格式的日期转换，可以通过替换格式，定义多个dateEditor，代码不够简洁
        DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        CustomDateEditor dateEditor = new CustomDateEditor(df, true);
        binder.registerCustomEditor(Date.class, dateEditor);
 
 
        // 方法3，同样注册converter
        binder.registerCustomEditor(Date.class, new PropertyEditorSupport() {
            @Override
            public void setAsText(String text) throws IllegalArgumentException {
                setValue(new DateConverter().convert(text));
            }
        });
    }
}
