任何人都可以在什么情况下启发我我会在日志中出现以下错误？Struts2 JasonInterceptor内容类型必须是'application/json'或'application/json-rpc'
Struts2 JasonInterceptor Content type must be 'application/json' or 'application/json-> rpc'. Ignoring request with content type application/x-www-form-urlencoded
我还注意到，在IE它示出了调试消息如下（不知道这些2个消息是相关的）：
DEBUG: please consider using a mimetype of text/json-comment-filtered to avoid potential >security issues with JSON endpoints DEBUG: [SyntaxError: Syntax error]
我特别改变了S：形式enctype属性如下仍然想不出摆脱这个消息：
<s:form id="dealerForm" action="AjaxAutocompleterAction"
enctype="text/json-comment-filtered">
</s:form>
，这也（didnt再次工作）
<s:form id="dealerForm" action="AjaxAutocompleterAction"
enctype="application/json">
</s:form>
有什么想法？

约我一起工作的代码详细信息如下：
我 AjaxAutocompleter.jsp包含链接autocompleters：
<s:form id="dealerForm" action="AjaxAutocompleterAction"
enctype="text/json-comment-filtered">
<sx:autocompleter id="dealer" name="dealer" searchType="substring"
label="Dealer" list="dealerList" listKey="name" listValue="name"
showDownArrow="false" valueNotifyTopics="/notifyBranch"
errorNotifyTopics="/error" beforeNotifyTopics="/before"
forceValidOption="true" loadMinimumCount="3" />
<sx:autocompleter id="branch" name="branch" searchType="substring"
label="Branch" list="branchList" showDownArrow="false"
listenTopics="/notifyBranch" formId="dealerForm"
formFilter="function(paramName){return true;}"
valueNotifyTopics="/notifyRep" beforeNotifyTopics="/before"
afterNotifyTopics="/after" forceValidOption="true"
loadMinimumCount="0" loadMinimumCount="3" />
<sx:autocompleter id="representative" name="representative"
searchType="substring" label="Rep" list="repList"
showDownArrow="false" forceValidOption="true" loadMinimumCount="0"
formId="dealerForm" formFilter="function(paramName){return true;}"
listenTopics="/notifyRep" beforeNotifyTopics="/before"
afterNotifyTopics="/after" loadMinimumCount="3" />
<textarea name="mytextarea" id="mytextarea" rows="25" cols="190"></textarea>
</s:form>
struts.xml的
<package name="ajax" extends="json-default">
<action name="AjaxAutocompleterAction" class="com.frk.gid.action.AjaxAutocompleterAction">
<interceptor-ref name="json"/>
<interceptor-ref name="params">
<param name="ordered">true</param>
</interceptor-ref>
<interceptor-ref name="prepare" />
<result type="json" />
<result name="success">/AjaxAutocompleter.jsp</result>
</action>

我准备方法
@Override
public void prepare() throws Exception {
logger.info("Prepare Started ...");
ServletActionContext.getResponse().setContentType(
"text/json-comment-filtered");
dealerList = new ArrayList<Dealer>();
int branchCounter = 0;
int repCounter = 0;
for (int i = 0; i < 5; i++) {
Dealer d = new Dealer();
List<Branch> branches = new ArrayList<Branch>();
for (int j = 0; j < 3; j++) {
Branch b = new Branch();
b.setName("BRANCH-" + branchCounter++);
List<Representative> representatives = new ArrayList<Representative>();
for (int k = 0; k < 2; k++) {
Representative rep = new Representative();
rep.setName("REP-" + repCounter++);
representatives.add(rep);
}
b.setRepresentatives(representatives);
branches.add(b);
}
d.setName("DEALER-" + i);
d.setBranches(branches);
dealerList.add(d);
if (this.dealer == null && i == 0) {
setDealer(d.getName());
}
// Populate DBR Hierarchy for the selected dealer.
if (this.dealer != null && this.dealer.equals(d.getName())) {
branchList = new ArrayList<String>();
int bCount = 0;
for (Branch b : branches) {
branchList.add(b.getName());
if (this.branch == null && bCount++ == 0) {
setBranch(b.getName());
}
if (this.branch != null && this.branch.equals(b.getName())) {
repList = new ArrayList<String>();
for (Representative r : b.getRepresentatives()) {
repList.add(r.getName());
}
if ((this.representative == null && repList.size() > 0)
|| (this.representative != null && !repList
.contains(this.representative))) {
setRepresentative(repList.get(0));
}
}
}
}
}
你能描述究竟你在做什么？ – 2012-03-29 11:30:21
我正在尝试一个struts2 **链接** autocompleter - 在autocompleter1中选择一个值时，值将在autocompleter2中刷新。网络中有一些可用的例子，但是由于上面描述的这个问题，无法让它们工作。 – Vikram 2012-03-29 13:07:26
不知道为什么你在准备方法中做了这么繁重的工作，还有更多的不确定如何使用json interceptor ref stack，而同样的方法可以用于简单的方式。请参阅此处获取更多详细信息http://stackoverflow.com/questions/ 8886713/struts2-json-interceptor-not-populating-my-action-class – 2012-03-29 14:11:36
