java - 如何在struts2中只返回数组而不是json对象

Question

<action name="commissioner_info" method="commissioner_info" class="foo.bar.AdminInfoAction">
    <result name="json" type="json">    
        <param name="includeProperties">
            commissioner_info\[\d+\]\.fname,
            commissioner_info\[\d+\]\.designation,        
            commissioner_info\[\d+\]\.pathlocation
        </param>
    </result>
</action>

上面给出结果的代码：

{"commissioner_info":[{"designation":"IG1","fname":"BS  Bassi ","pathlocation":"http:\/\/103.231.125.106\/nesos\/imagerepresentatives\/151021104556Bhim.jpg"}]}

但我只想要数组而不是 json 对象，比如

[{"designation":"IG1","fname":"BS  Bassi ","pathlocation":"http:\/\/103.231.125.106\/nesos\/imagerepresentatives\/151021104556Bhim.jpg"}]

Answer 1

您需要指定要序列化为根对象的对象：

<result name="json" type="json">    
    <param name="root">
        commissioner_info
    </param>
</result>

否则整个动作将被序列化。在这里阅读更多。
