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
