设置哪些属性要序列化哪些不需要序列化;

Customizing Serialization and Deserialization

Use the JSON annotation to customize the serialization/deserialization process. Available JSON annotation fields:

Name	Description	Default Value	Serialization	Deserialization
name	Customize field name	empty	yes	no
serialize	Include in serialization	true	yes	no
deserialize	Include in deserialization	true	no	yes
format	Format used to format/parse a Date field	"yyyy-MM-dd'T'HH:mm:ss"	yes	yes

Excluding properties

A comma-delimited list of regular expressions can be passed to the JSON Result and Interceptor, properties matching any of these regular expressions will be ignored on the serialization process:

<!-- Result fragment -->
<result type="json">
<param name="excludeProperties">
login.password,
studentList.*\.sin
</param>
</result>

<!-- Interceptor fragment -->
<interceptor-ref name="json">
<param name="enableSMD">true</param>
<param name="excludeProperties">
login.password,
studentList.*\.sin
</param>
</interceptor-ref>

Including properties

A comma-delimited list of regular expressions can be passed to the JSON Result to restrict which properties will be serialized. ONLY properties matching any of these regular expressions will be included in the serialized output.

Note Exclude property expressions take precedence over include property expressions. That is, if you use include and exclude property expressions on the same result, include property expressions will not be applied if an exclude exclude property expression matches a property first.

<!-- Result fragment -->
<result type="json">
<param name="includeProperties">
^entries\[\d+\]\.clientNumber,
^entries\[\d+\]\.scheduleNumber,
^entries\[\d+\]\.createUserId
</param>
</result>
