Spring Rest中的自定义JsonConfiguration

@Configuration
public class CustomJsonConfiguration extends WebMvcConfigurerAdapter {

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        // 创建一个自定义的HttpMessageConverter
        MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        
        // 创建一个自定义的ObjectMapper
        ObjectMapper objectMapper = new ObjectMapper();
        
        // 配置ObjectMapper，例如修改日期格式
        objectMapper.setDateFormat(new SimpleDateFormat("yyyy-MM-dd"));
        
        // 设置自定义的ObjectMapper到HttpMessageConverter中
        converter.setObjectMapper(objectMapper);
        
        // 添加自定义的HttpMessageConverter到converters中
        converters.add(converter);
        
        // 调用父类的configureMessageConverters方法
        super.configureMessageConverters(converters);
    }
}
