Could not read document: Unrecognized field "***" 解決方案！

org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver.handleHttpMessageNotReadable Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Could not read document: Unrecognized field "age1" (class com.byd.shop.entity.User), not marked as ignorable (4 known properties: "id", "sex", "age", "name"])

1、原因分析

實體類中不存在post提交的age1，從而程序拋出異常。

2、在實體類添加  @JsonIgnoreProperties(ignoreUnknown = true)

3、springweb.xml添加

<mvc:annotation-driven>
    <mvc:message-converters register-defaults="true">
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="objectMapper">
                <bean class="com.fasterxml.jackson.databind.ObjectMapper">
                    <!-- 處理responseBody 裏面日期類型 -->
                    <property name="dateFormat">
                        <bean class="java.text.SimpleDateFormat">
                            <constructor-arg type="java.lang.String" value="yyyy-MM-dd HH:mm:ss"/>
                        </bean>
                    </property>
                    <!-- 爲null字段時不顯示 -->
                    <property name="serializationInclusion">
                        <value type="com.fasterxml.jackson.annotation.JsonInclude.Include">NON_NULL</value>
                        <!--//將該標記放在屬性上，如果該屬性爲NULL則不參與序列化-->
                        <!--//如果放在類上邊,那對這個類的全部屬性起作用-->
                        <!--//Include.Include.ALWAYS 默認-->
                        <!--//Include.NON_DEFAULT 屬性爲默認值不序列化-->
                        <!--//Include.NON_EMPTY 屬性爲 空（“”） 或者爲 NULL 都不序列化-->
                        <!--//Include.NON_NULL 屬性爲NULL 不序列化-->
                    </property>
                </bean>
            </property>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

4、重啓即可。
