REST服务中的WSo2 ESB 4.0.3和JSON [英] WSo2 ESB 4.0.3 and JSON in REST service
问题描述
我正在尝试使用REST服务在WSB403中吐出JSON输出，但我一直非常失败.我按照以下链接中概述的步骤进行操作.
I am trying to use a REST service spit out a JSON output in WSB403 and I have been highly unsuccessful. I followed the steps outlined from the below link.
我添加了DynamicResponseModule，并且已对其进行全局分配.
I have added the DynamicResponseModule and I have it assigned globally.
正常运行REST服务时，将按预期方式获得XML格式的输出，但是当我尝试添加"response=json"时，我的服务超时并得到以下堆栈跟踪.
When I run the REST service normally, I get a XML formatted output as expected, but when I try to add a "response=json", my service times out and I get the following stacktrace.
内部DynamicResponseModule应该将此responseType映射到application/JSON/Badgerfish，并且在这样做时，我得到以下堆栈跟踪.
Internally the DynamicResponseModule is supposed to map this responseType to application/JSON/Badgerfish and when it does that I get the following stack trace.

知道我在这里想念什么吗?
Any idea what am I missing here ?

推荐答案
您可能会从示例中得到启发[1]. (请注意，如果要从json切换到soap11，则必须将端点格式设置为soap11.)
You may inspire from the sample[1]. (Please note that if you want to switch from json to soap11, then you have to set the endpoint format to soap11.)
在axis2.xml中使用json消息生成器和格式器设置正确的内容类型(例如，application/json)
Use json message builder and formtter in the axis2.xml for the correct content type (e.g. application/json for instance)
