springboot默認采用的是jackson解析json,在未進行配置的情況下會出現(xiàn)值為空的鍵丟失的情況,網(wǎng)上有配置的方案,但不能解決全部問題,這里采用更換json解析工具的解決辦法,
引入fastjson jar包
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>${fastjson.version}</version>
</dependency>
添加configbean
import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
import org.springframework.boot.autoconfigure.web.HttpMessageConverters;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.HttpMessageConverter;
@Configuration
public class BeanConfig {
/*注入Bean : HttpMessageConverters，以支持fastjson*/
@Bean
public HttpMessageConverters fastJsonHttpMessageConverters() {
FastJsonHttpMessageConverter fastConvert = new FastJsonHttpMessageConverter();
FastJsonConfig fastJsonConfig = new FastJsonConfig();
fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat,
SerializerFeature.WriteNullStringAsEmpty,
SerializerFeature.WriteNullNumberAsZero,
SerializerFeature.WriteNullListAsEmpty,
SerializerFeature.WriteMapNullValue,
SerializerFeature.DisableCheckSpecialChar);
fastJsonConfig.setDateFormat("yyyy-MM-dd hh:mm:ss");
//處理中文亂碼問題
List<MediaType> fastMediaTypes = new ArrayList<>();
fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
fastConvert.setSupportedMediaTypes(fastMediaTypes);
fastConvert.setFastJsonConfig(fastJsonConfig);
return new HttpMessageConverters((HttpMessageConverter<?>) fastConvert);
}
}
fastjon 的詳細配置 在這篇文章中講的很詳細,就不一 一敘述了
