通过使用strut2 jQuery插件标签将JSON对象发送到Struts 2操作 [英] Send JSON object to Struts 2 action by using strut2 jquery plugin tags

问题描述

我们可以通过json拦截器将JSON发送到Struts2操作. http://tech.learnerandtutor.com/send-json-object-to-struts-2-action-by-jquery-ajax/.

We can send JSON to Struts2 actions by json interceptor. There is good sample at http://tech.learnerandtutor.com/send-json-object-to-struts-2-action-by-jquery-ajax/.

json拦截器要求请求content type是application/json或application/json-rpc，当我们直接使用Ajax时可以设置此请求:

The json interceptor requires that the requests content type be application/json or application/json-rpc this can be set when we directly use Ajax like:

$.ajax({
    url: "writeJSON.action",
    data: data1,
    dataType: 'json',
    contentType: 'application/json',

但是我们正在使用struts 2 jquery插件标签(sj:a和sj:submit ...)，这些标签为我们管理ajax调用.

But we are using struts 2 jquery plugin tags (sj:a and sj:submit ...) which manage ajax calls for us.

有什么方法可以使用这些标签设置contentType.

Is there any way that we can set the contentType with these tags.

我没有为此找到标签属性.

I did not find tag properties for this.

如果未实现，还有其他设置方法.

If it is not implemented is there any other way to set it.

推荐答案

您应将Content-type: application/json标头设置为$.ajax()使用的xhr对象.

You should set Content-type: application/json header to xhr object that is used by the $.ajax().

$.ajax({
    url: "writeJSON.action",
    data: data1,
    dataType: 'json',
    contentType: 'application/json',

该插件正在使用$.ajaxSubmit()，应取消这种提交方式，因为它不适用于json数据.

The plugin is using $.ajaxSubmit(), this kind of submission should be eliminated because it doesn't work with json data.
