加上@DateTimeFormat注解之后依然失败。
解决办法
使用fastjson替换springboot原本的jackson
添加依赖
编写配置类
配置类中需要注意设置的日期格式
import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import java.nio.charset.StandardCharsets;
import java.util.ArrayList;
import java.util.List;
@Configuration
@EnableWebMvc // 必须要有这个注解,否则报错
public class WebConfig implements WebMvcConfigurer {
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
FastJsonHttpMessageConverter fastJsonConverter = new FastJsonHttpMessageConverter();
FastJsonConfig config = new FastJsonConfig();
config.setCharset(StandardCharsets.UTF_8);
config.setDateFormat("yyyy-MM-dd HH:mm:ssS");
config.setSerializerFeatures(SerializerFeature.WriteMapNullValue);
fastJsonConverter.setFastJsonConfig(config);
List<MediaType> list = new ArrayList<>();
list.add(MediaType.APPLICATION_JSON);
fastJsonConverter.setSupportedMediaTypes(list);
converters.add(fastJsonConverter);
}
}
