Question

我无法让杰克逊正确地序列化日期。

它始终序列化为：

{"now":[2016,7,1,15,41,44,753]}

而不是：

{"now":"2016-07-01T15:41:44.753"}

这是我的来源：

package br.com.jjw.spring.jackson.bug;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication

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

Answer 1

我找到了一个解决方案，我刚刚将MvcConfig更改为WebMvcConfigurerAdapter。

package br.com.jjw.spring.jackson.bug;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("classpath:/public/");
    }

}

要添加，此帖子有助于了解Difference between WebMvcConfigurationSupport and WebMvcConfigurerAdapter

的原因

WRITE_DATES_AS_TIMESTAMPS没有在Spring boot 1.3.5上进行过woking
