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

 1 /**
 2  * Created by IntelliJ IDEA.
 3  *
 4  * @Auther: ShaoHsiung
 5  * @Date: 2018/8/29 15:42
 6  * @Title:
 7  * @Description: 自定义日期转换器
 8  */
 9 public class DateConverter implements Converter<String,Date> {
10     private SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
11     @Override
12     public Date convert(String s) {
13         if ("".equals(s) || s == null) {
14             return null;
15         }
16         try {
17             return simpleDateFormat.parse(s);
18         } catch (ParseException e) {
19             e.printStackTrace();
20         }
21         return null;
22     }
23 }

2.配置转换器

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

 1 /**
 2  * Created by IntelliJ IDEA.
 3  *
 4  * @Auther: ShaoHsiung
 5  * @Date: 2018/8/29 15:41
 6  * @Title:
 7  * @Description:
 8  */
 9 @Configuration
10 public class WebMvcConfig extends WebMvcConfigurerAdapter {
11     @Override
12     public void addFormatters(FormatterRegistry registry) {
13         registry.addConverter(new DateConverter());
14     }
15 }

3.编写测试controller

 1 /**
 2  * Created by IntelliJ IDEA.
 3  *
 4  * @Auther: ShaoHsiung
 5  * @Date: 2018/8/29 11:14
 6  * @Title: 
 7  * @Description: 测试日期转换器
 8  */
 9 @RestController
10 public class HelloController {
11     @RequestMapping(method = RequestMethod.GET, path = "/hello")
12     public String hello(Date date) {
13         // 测试简单类型
14         System.out.println(date);
15         
16         return "Hello SpringBoot";
17     }
18 }

4.测试方式和效果
