fastjson数据返回配置

阿里的fastjson 包升级后，可能导致返回的json 数据，字段为null时不显示等问题

<dependency>

    <groupId>com.alibaba</groupId>

    <artifactId>fastjson</artifactId>

    <version>1.9.13</version>

</dependency>

@Configuration

public class FastjsonConfiguration {

  @Bean

  public HttpMessageConverters fastjsonConverter() {

    FastJsonConfig fastJsonConfig = new FastJsonConfig();

    //自定义格式化输出

    fastJsonConfig.setSerializerFeatures(SerializerFeature.WriteNullStringAsEmpty, SerializerFeature.WriteNullNumberAsZero);

    FastJsonHttpMessageConverter4 fastjson = new FastJsonHttpMessageConverter4();

    fastjson.setFastJsonConfig(fastJsonConfig);

    return new HttpMessageConverters(fastjson);

  }

}

SerializerFeature  类的一些枚举值

    WriteMapNullValue,

    WriteNullListAsEmpty //  将list的null转成 []

    WriteNullStringAsEmpty // 将string的null转成 ""

    WriteNullNumberAsZero

    WriteNullBooleanAsFalse,

    PrettyFormat,

    WriteClassName,

    WriteDateUseDateFormat,

    NotWriteRootClassName,

    BeanToArray,

    WriteNonStringKeyAsString,

    NotWriteDefaultValue,

    BrowserSecure,

    IgnoreNonFieldGetter,

    WriteNonStringValueAsString,

springMVC 中设置

            <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">

                <property name="supportedMediaTypes">

                    <list>

                        <value>text/html;charset=UTF-8</value>

                        <value>application/json</value>

                    </list>

                </property>

                <property name="features">

                    <list>

                        <value>WriteMapNullValue</value>

                        <value>QuoteFieldNames</value>

                    </list>

                </property>

               <!--  <property name="dateFormat" value="yyyy-MM-dd HH:mm:ss"/> -->

            </bean>

2、脱敏设置

1 ）自定义 SensentiveField 类实现 ObjectSerializer，并重写其方法
2） @JSONField(serializeUsing =SensentiveField.class) 实体类的属性加上注解
