简介

很多时候日期格式输出是这样的 2018-10-09T17:39:07.097 中间有个T,尴尬,是的我们需要去掉这个T 这方法是springboot封装好了的,我们直接使用即可,普通的配置我就不贴了

教程

创建日期config类

@Configuration
public class LocalDateTimeSerializerConfig {
    @org.springframework.beans.factory.annotation.Value("${spring.jackson.date-format:yyyy-MM-dd HH:mm:ss}")
    private String pattern;

    @Bean
    public LocalDateTimeSerializer localDateTimeDeserializer() {
        return new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(pattern));
    }

    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
        return builder -> builder.serializerByType(LocalDateTime.class, localDateTimeDeserializer());
    }
}

实体类,get,set忽略

public class TestEntity {
    private String name;
    private LocalDateTime dateTimes;
}

controller使用

@GetMapping("/test")
    public TestEntity test(){
        TestEntity testEntity=new TestEntity();
        testEntity.setName("admin");
        testEntity.setDateTimes(LocalDateTime.now());
        return testEntity;
    }

成功效果

{"name":"admin","dateTimes":"2018-10-09 17:39:07"}
You can’t perform that action at this time.
