SpringBoot配置自定义日期参数转换器

1.自定义参数转换器

自定义参数转换器必须实现Converter接口

 /**
  * Created by IntelliJ IDEA.
  *
  * @Auther: ShaoHsiung
  * @Date: 2018/8/29 15:42
  * @Title:
  * @Description: 自定义日期转换器
  */
 public class DateConverter implements Converter<String,Date> {
     private SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
     @Override
     public Date convert(String s) {
         if ("".equals(s) || s == null) {
             return null;
         }
         try {
             return simpleDateFormat.parse(s);
         } catch (ParseException e) {
             e.printStackTrace();
         }
         return null;
     }
 }

2.配置转换器

自定义WebMvcConfig继承WebMvcConfigurerAdapter，在addFormatters方法中进行配置：

 /**
  * Created by IntelliJ IDEA.
  *
  * @Auther: ShaoHsiung
  * @Date: 2018/8/29 15:41
  * @Title:
  * @Description:
  */
 @Configuration
 public class WebMvcConfig extends WebMvcConfigurerAdapter {
     @Override
     public void addFormatters(FormatterRegistry registry) {
         registry.addConverter(new DateConverter());
     }
 }

3.编写测试controller

 /**
  * Created by IntelliJ IDEA.
  *
  * @Auther: ShaoHsiung
  * @Date: 2018/8/29 11:14
  * @Title:
  * @Description: 测试日期转换器
  */
 @RestController
 public class HelloController {
     @RequestMapping(method = RequestMethod.GET, path = "/hello")
     public String hello(Date date) {
         // 测试简单类型
         System.out.println(date);

         return "Hello SpringBoot";
     }
 }

4.测试方式和效果
