I am converting my app to get rid of spring-boot, it now uses only Spring (5.3).
I've added the @EnableWebMvc
configuration and I have my endpoints working properly for the most part - they return the data I want as JSON.
Previously, I customised the date format with the spring-boot property: spring.jackson.date-format=yyyy-MM-dd'T'HH:mm:ss.SSS'Z'
In the new pure-spring app though, it's regressed back serializing to a long
value.
I've tried the following, but it doesn't seem to even use these beans at all:
@Bean
public ObjectMapper objectMapper() {
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
ObjectMapper dateFormatMapper = new ObjectMapper();
dateFormatMapper.setDateFormat(dateFormat);
return dateFormatMapper;
}
@Bean
public MappingJackson2HttpMessageConverter mappingJackson2JsonView(){
var converter = new MappingJackson2HttpMessageConverter();
converter.getObjectMapper().setDateFormat(
new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'") );
return converter;
}
I'm looking to customise the format globally, not on a per-field basis.
What would be the equivalent of spring.jackson.date-format
for pure Spring @EnableWebMvc
setup?
CodePudding user response:
You can customize MappingJackson2HttpMessageConverter
by using WebMvcConfigurer
with @EnableWebMvc
.
For example:
@Configuration
@EnableWebMvc
public class YourConfiguration implements WebMvcConfigurer {
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder()
.indentOutput(true)
.dateFormat(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"));
converters.add(new MappingJackson2HttpMessageConverter(builder.build()));
}
}
