使用Spring Boot 2.3.4.RELEASE Jackson2ObjectMapper将LocalDate序列化为时间戳

问题描述

我尝试了几种方法来更改Spring Boot内的默认杰克逊配置，但它不起作用。 它只是忽略了所有配置

@SpringBootApplication 公共类AvaliacaoairtonApplication {

public static final String URL = "*";

public static void main(String[] args) {
    SpringApplication.run(AvaliacaoairtonApplication.class,args);
}

@Bean
@Primary
public ObjectMapper objectMapper(Jackson2ObjectMapperBuilder builder) {

    ObjectMapper objectMapper = builder.build();

    objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS,false);

    JavaTimeModule javaTimeModule = new JavaTimeModule();
    javaTimeModule.addSerializer(LocalDate.class,new StdScalarserializer<LocalDate>(LocalDate.class) {

        @Override
        public void serialize(LocalDate localDate,JsonGenerator jsonGenerator,SerializerProvider serializerProvider) throws IOException {

            jsonGenerator.writeString(localDate.format(DateTimeFormatter.ofPattern("yyyy-MM-dd")));
        }
    });

    objectMapper.registerModule(javaTimeModule);

    return objectMapper;
}

}

application.properties spring.jackson.serialization.write-dates-as-timestamps = false
