解决方法就是将Long型转换为字符串---全局配置方案如下：
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
// 初始化转换器
FastJsonHttpMessageConverter fastConvert = new FastJsonHttpMessageConverter();
// 初始化一个转换器配置
FastJsonConfig fastJsonConfig = new FastJsonConfig();
JSON.DEFFAULT_DATE_FORMAT = "yyyy-MM-dd HH:mm";
fastJsonConfig.setSerializerFeatures(SerializerFeature.BrowserCompatible,
SerializerFeature.WriteNullListAsEmpty,
SerializerFeature.PrettyFormat,
SerializerFeature.WriteDateUseDateFormat,
SerializerFeature.WriteNullStringAsEmpty,
SerializerFeature.WriteMapNullValue,
SerializerFeature.DisableCircularReferenceDetect);
//解决Long转json精度丢失的问题
SerializeConfig serializeConfig = SerializeConfig.globalInstance;
serializeConfig.put(BigInteger.class, ToStringSerializer.instance);
serializeConfig.put(Long.class, ToStringSerializer.instance);
serializeConfig.put(Long.TYPE, ToStringSerializer.instance);
fastJsonConfig.setSerializeConfig(serializeConfig);
// 将配置设置给转换器并添加到HttpMessageConverter转换器列表中
fastConvert.setFastJsonConfig(fastJsonConfig);
converters.add(fastConvert);
}
@Override
public
