SpringBoot开源项目学习总结

一、实现日期格式数据类型的转换

首先，定义DateConverter实现Converter<String, Date>接口：

 1 package com.stevlu.common;
 2 
 3 import org.springframework.core.convert.converter.Converter;
 4 
 5 import java.text.ParseException;
 6 import java.text.SimpleDateFormat;
 7 import java.util.Date;
 8 
 9 /**

12 public class DateConverter implements Converter<String, Date> {
13     private SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd");
14 
15     @Override
16     public Date convert(String s) {
17         if ("".equals(s) || s == null) {
18             return null;
19         }
20         try {
21             return simpleDateFormat.parse(s);
22         } catch (ParseException e) {
23             e.printStackTrace();
24         }
25         return null;
26     }
27 }
