不知道为什么此(来自someactionBean.java的附加方法)在Google App Engine上不起作用?当地的一切都完美无缺。任何想在哪里寻找解决方案?

 /**
 * @return Page to display, filled with correct data
 */
@DefaultHandler
public Resolution welcome() {
    Resolution fd = new ForwardResolution(VIEW);
    HttpServletRequest request = this.ctx.getRequest();
    if(request.getMethod() == "POST") { 
        String content = getRequestContent(request);
        updateData(content);
    }else if (request.getMethod() == "GET"){
        String ct = request.getContentType();
        if(("application/json").equals(ct))
            try {
                getNotesJson(); //fill returnJson global variable
                fd = new JSONResolution(returnJson);
                //TODO Spread to other entities
            } catch (JSONException e) {
                e.printStackTrace();
            }
    }
    return fd;
}
有帮助吗?

解决方案

细绳 比较是错误的:

request.getMethod() == "POST"

爪哇字符串不是原始的,因此应通过 等于 方法:

"POST".equals(request.getMethod())
