我使用 Struts2 Convention 插件来映射我的操作。请帮我解决以下问题。这里我有一个动作映射
@Action(value="/{categorie:\\w+}/{hoofdgroep:\\w+}/{artikelgroep:\\w+}/", results = {
@Result(name="success", location="articlelist.jsp"),
@Result(name="maingroup", location="/%{categorie}/%{hoofdgroep}/", type="redirect"),
@Result(name="category", location="/%{categorie}/", type="redirect")
}, interceptorRefs = {
...
})
public String execute() throws Exception {
...
Category category = service.getCategory(categorie);
if (category == null) return NONE;
...
MainGroup mGroup = service.getMainGroup(hoofdgroep);
if (mGroup == null) return "category";
...
ArticleGroup artGroup = service.getArticleGroup(artikelgroep);
if (artGroup == null) return "maingroup";
...
return SUCCESS;
}
例如，当没有指定 artikelgroep 的 artGroup 时，它应该重定向到它完美执行link _http://site/categorie/hoofdgroep/artikelgroep/的 url 。_http://site/categorie/hoofdgroep/这里唯一的问题是它还预先添加了不需要的附加参数。所以链接_http://site/categorie/hoofdgroep/artikelgroep/被重定向到_http://site/categorie/hoofdgroep/?categorie=categorie&hoofdgroep=hoofdgroep&artikelgroep=artikelgroep.
我的问题是如何摆脱这些参数？
这是我的 struts.properties 文件中的一些配置参数
...
struts.serve.static=false
struts.ognl.allowStaticMethodAccess=true
struts.enable.DynamicMethodInvocation=false
struts.action.extension= ,
struts.url.includeParams=none
struts.enable.SlashesInActionNames=true
struts.mapper.alwaysSelectFullNamespace=false
struts.patternMatcher=regex
struts.convention.default.parent.package=app-default
struts.convention.action.packages=...
struts.convention.action.alwaysMapExecute=false
struts.convention.package.locators.disable=true
struts.convention.relative.result.types=dispatcher
struts.convention.result.path=/WEB-INF/jsp/
所以基本上这是一个错误还是应该以这种方式工作？
也许这不是那么优雅的解决方案，但在这里我做了什么。我超越了org.apache.struts2.dispatcher.ServletRedirectResult#getProhibitedResultParams
public class ServletRedirectResult
extends org.apache.struts2.dispatcher.ServletRedirectResult
{
public ServletRedirectResult() {
super();
initProhibitedResultParams();
}
public ServletRedirectResult(String location) {
super(location);
initProhibitedResultParams();
}
public ServletRedirectResult(String location, String anchor) {
super(location, anchor);
initProhibitedResultParams();
}
private List<String> prohibitedParamNames;
private void initProhibitedResultParams() {
String[] parentParams = (String[])super.getProhibitedResultParams().toArray();
int len = parentParams.length;
String[] params = new String[len + 4];
for (int i = 0; i < len; i++) {
params[i] = parentParams[i];
}
params[len] = "statusCode";
// TODO: This is a temporary solution because RegexPatternMatcher puts parameters
// from urls into ResultConfig for some reason.
params[len+1] = "categorie";
params[len+2] = "hoofdgroep";
params[len+3] = "artikelgroep";
prohibitedParamNames = Arrays.asList(params);
}
protected List<String> getProhibitedResultParams() {
return prohibitedParamNames;
}
}
