Php 让QuercusView与SpringMVC协同工作

我正在尝试实现SpringMVC+Quercus，如中所述

因此，我将Spring设置为：

@Controller
@RequestMapping("account/*")
public class AccountController {

  public AccountController() {}

  @RequestMapping("signup")
    public String signupTestHandler() {
        return "signup";
    }

}

我使用Tomcat+openejb+Spring3作为EJB容器

谢谢你的帮助

拜托，我不太了解SpringMVC和Quercus的内部工作原理，但我希望有人能帮助我解决这个问题

谢谢你的帮助

工作副本 斯坦尔是对的，也许是旧版本，但他们忘了添加开始

protected QuercusContext getQuercus()
  {
    synchronized (this) {
      if (this._quercus == null) {
        this._quercus = new QuercusContext();
         this._quercus.start();
      }
    }
    return this._quercus;
  }

如果您想从java传递到php，那么必须使用env.setGlobalValue 斯坦尔是对的，也许是旧版本，但他们忘了添加开始

protected QuercusContext getQuercus()
  {
    synchronized (this) {
      if (this._quercus == null) {
        this._quercus = new QuercusContext();
         this._quercus.start();

我对Quercus不太熟悉，但是通过查看（第265行），计时器似乎没有实例化；（2042）耶。但是您得到的

NullPointerException

显示_querycustimer为null。可能永远不会调用

start（）

方法？好的。我想这可能就是问题所在。我认为QuercusView.java需要打包成一个jar文件并放到类路径中。我怀疑类加载的顺序有问题。为了在我的类路径中包含QuercusView，我现在所做的是在我的项目包结构中包含源文件。这样做我感觉不太好。我将它打包到一个罐子中，但它仍然不起作用。我不熟悉Quercus，但通过查看（第265行），计时器似乎没有实例化。请参见_quercusTimer=new quercusTimer（）；（2042）耶。但是您得到的
