JackSon反序列化報錯,Unrecognized field, not marked as ignorable

1.報錯的情景

字段	JavaBean	redis	是否報錯
包含字段	a,b	a	否
包含字段	a	a,b	是

2.解決辦法

• 2.1對于JaveBean的類定義上加上注解

@JsonIgnoreProperties(ignoreUnknown = true)  
public Class Bean{
}
           

• 2.2設定jackson的序列化配置

ObjectMapper objectMapper=new ObjectMapper();
        objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,false);
jackson.setObjectMapper(objectMapper);
