Struts2的JSON插件

Struts可以返回为JSON的形式。

文档
中文文档：http://webservices.ctocio.com.cn/tips/424/7670924.shtml
英文文档：http://cwiki.apache.org/S2PLUGINS/json-plugin.html（详细些）

有几个需要注意的地方:
1: 如果不序列化某个属性需要在get方法上加入@JSON(deserialize=false,serialize=false)注释。
2: struts2.0包必须继承json-default，<package name="default" extends="json-default">
3：struts设置为UTF-8 , <constant name="struts.i18n.encoding" value="UTF-8" />
4: Model的访问控制符必须是public的，public static class Model
5：设置返回类型为：json
<action name="knowledgeAction" class="KnowledgeAction">
       <result type="json" >
      </result>
</action>


输入的JAVA对象：

List<Knowledge> knowledges = new ArrayList<Knowledge>();
  //创建对象
  Knowledge knowledge = new Knowledge();
  knowledge.setInfoId("know1000");
  knowledge.setInfoTitle("infoTitle");
  knowledge.setCreatorId("creatorId1000");
  knowledge.setCreatorName("creatorName");
  knowledge.setCreateTime(new Date());
  knowledge.setAuditorId("auditorId1000");
  knowledge.setAuditorName("auditorName");
  knowledge.setAuditTime(new Date());
  knowledge.setStatus(300.2512);
  knowledge.setInfoType("infoType");
  knowledge.setCategoryId("categoryId1000");
  knowledge.setReadCount(29.23);
  knowledge.setInfoLevel(12.3);
  knowledge.setModifierId("modifierId1000");
  knowledge.setModifierName("modifierName");
  knowledge.setModifyTime(new Date());
  knowledges.add(knowledge);

输出的JSON对象

{"model":{"knowledges":
[
{"auditTime":"2008-10-20 17:52:48",
"auditorId":"auditorId1000",
"auditorName":"auditorName",
"categoryId":"categoryId1000",
"createTime":"2008-10-20 17:52:48","creatorId":"creatorId1000",
"creatorName":"creatorName",
"infoId":"know1000",
"infoLevel":12.3,
"infoTitle":"infoTitle",
"infoType":"infoType","modifierId":"modifierId1000","modifyTime":"2008-10-20 17:52:48","readCount":29.23,"status":300.2512}]}}
