springboot接收日期字符串参数与返回日期字符串类型格式化

@Configuration
public class WebConfig implements WebMvcConfigurer {
    @Override
    public void addFormatters(FormatterRegistry registry) {
        registry.addFormatter(new Formatter<Date>() {
            @Override
            public Date parse(String date, Locale locale) {
                return new Date(Long.parseLong(date));
            }

            @Override
            public String print(Date date, Locale locale) {
                return Long.valueOf(date.getTime()).toString();
            }
        });
    }
}

// 在参数上加入该注解
@GetMapping("/testDate")
public void test(@DateTimeFormat(pattern = "yyyy-MM-dd")Date date){
}

@Data
public class User{
    private String name;
    @DateTimeFormat(pattern = "yyyy-MM-dd")
    private Date birthday;
}

// 在接收类字段加入该注解
@PostMapping("/testDate")
public void addUser(@RequestBody User user){
}

@Configuration
public class MyWebMvcConfigurer implements WebMvcConfigurer {
     @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
    //调用父类的配置
        super.configureMessageConverters(converters);
        //创建fastJson消息转换器
        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
        //创建配置类
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig .setDateFormat("yyyy-MM-dd HH:mm:ss");
        //保留空的字段
        fastJsonConfig .setSerializerFeatures(SerializerFeature.WriteMapNullValue);
        // 按需配置，更多参考FastJson文档
        fastConverter .setFastJsonConfig(config);
        fastConverter .setDefaultCharset(Charset.forName("UTF-8"));
        converters.add(fastConverter );
    }
}

@Data
public class User{
    private String name;
    @JsonFormat(pattern="yyyy/MM/dd HH:mm:ss",timezone = "GMT+8")
    private Date birthday;
}
