Spring自定义格式化程序未被调用

Question

我正在使用spring框架处理rest api。 我尝试使用spring-boot的自定义格式化程序的所有尝试都没有产生任何结果。 自定义Annotation格式化程序应格式化LocalDate，LocalDateTime和Dates。

即使是预先存在的spring格式化程序（@DateTimeFormat，@ NumberFormat）也不起作用。

这篇文章Spring: custom validator is not being called类似，但我没有注意到我的代码中存在任何不匹配。

关于自定义格式化程序的在线示例使用jsp来获取值。它们可以用于基于弹簧休息的项目而不是mvc吗？可能我使用格式化程序的方式不正确。

非常感谢任何帮助。

由于

public class BroadcastDateFormatter implements Formatter<LocalDate>
{

@Override
public String print(LocalDate object, Locale locale)
{
    // TODO Auto-generated method stub
    return null;
}

@Override
public LocalDate parse(String text, Locale locale)
    throws ParseException
{
    // TODO Auto-generated method stub
    return null;
}

} 


public class BroadcastLocalDateFormatterAnnotationFactory implements     AnnotationFormatterFactory<BroadcastLocalDateFormat>
{

@Override
public Set<Class<?>> getFieldTypes()
{
    Set<Class<?>> classes = new HashSet<>();
    classes.add(LocalDate.class);
    classes.add(LocalDateTime.class);
    classes.add(Date.class);
    return classes;
}

@Override
public Printer<?> getPrinter(BroadcastLocalDateFormat annotation, Class<?> fieldType)
{
    return new BroadcastDateFormatter();
}

@Override
public Parser<?> getParser(BroadcastLocalDateFormat annotation, Class<?> fieldType)
{
    return new BroadcastDateFormatter();
}

}

@Configuration
@EnableWebMvc
@EnableJpaRepositories(basePackages = { "com.test.*" })
@EntityScan(basePackages = { "com.test.*" })
@EnableAutoConfiguration(exclude = {    DataSourceTransactionManagerAutoConfiguration.class,   HibernateJpaAutoConfiguration.class })
public class AppConfig
extends WebMvcConfigurerAdapter
{
@Override
public void addFormatters(FormatterRegistry registry)
{
    registry.addConverter(new FilterExpressionConverter());
    registry.addFormatterForFieldAnnotation(new BroadcastLocalDateFormatterAnnotationFactory());
    registry.addFormatterForFieldAnnotation(new SSNAnnotationFormatterFactory());
    registry.addFormatter(new SSNFormatter());
    registry.addFormatter(new BroadcastDateFormatter());
}


public class FooDomain
{
@JsonProperty(value="my_current_date")
@DateTimeFormat(pattern = "dd/MM/yyyy")
@JsonFormat(shape=JsonFormat.Shape.STRING, pattern="yyyy-MM-d")
private LocalDate currentDate;

@BroadcastLocalDateFormat
private LocalDate broadcastDate;

@NumberFormat(style=Style.CURRENCY, pattern = "#,###.###")
private Double currency;
}
