@Bean
@Scope("singleton")
public ObjectMapper objectMapper(){
return new ObjectMapper();
}
声明这个json处理会覆盖掉spring的,导致json解析失败
下面是使用自定义的fastjson
自定义springboot配置
@Configuration
@ConditionalOnClass({FastJsonHttpMessageConverter.class})
@ConditionalOnProperty(
name = {"spring.http.converters.preferred-json-mapper"},
havingValue = "fastjson",
matchIfMissing = true
)
static class FastJson2HttpMessageConverterConfiguration{
@Bean
@ConditionalOnMissingBean({FastJsonHttpMessageConverter.class})
public FastJsonHttpMessageConverter fastJsonHttpMessageConverter() {
FastJsonHttpMessageConverter converter = new FastJsonHttpMessageConverter();
FastJsonConfig fastJsonConfig = new FastJsonConfig();
fastJsonConfig.setSerializerFeatures(
SerializerFeature.WriteMapNullValue,
SerializerFeature.WriteNullNumberAsZero,
SerializerFeature.WriteNullListAsEmpty,
SerializerFeature.WriteNullStringAsEmpty,
SerializerFeature.WriteNullBooleanAsFalse,
SerializerFeature.WriteDateUseDateFormat,
SerializerFeature.PrettyFormat,
SerializerFeature.WriteClassName
);
converter.setFastJsonConfig(fastJsonConfig);
return converter;
}
}
