JSF与Nutz.dao结合使用出现异常

GoogleCodeExporter commented 9 years ago

问题产生的条件：
在JSF的BackBean中使用Nutz.Dao

发生问题的调用代码：
index.xhtml代码：

    public String action(){
      String result = null;
    BasicDataSource ds = new BasicDataSource();
    ds.setDriverClassName("com.mysql.jdbc.Driver");
    ds.setUrl("jdbc:mysql://localhost:3306/jobdb");

    NutDao dao = new NutDao(ds);
    System.out.println("---------->dao" + dao);
    System.out.println("---------->ds=" + dao.getDataSource());

    User user = new User();
    user.setUserid("30001786");
    user.setUsername("肖磊");
    user.setUserpwd("1234");
    user.setUserrole(9);

    dao.insert(user);

      return result;

你用的是什么版本呢?

GoogleCodeExporter commented 9 years ago

问题产生的原因:
1. LocalResourceScan的83行没有判断pos是否大于0
2. 在Web环境,但不使用NutMVC的情况下, 
Scans类就使用LocalResourceScan而非WebResourceScan

解决:
1. 修正LocalResourceScan的bug
2. 在哪个文档里面提醒一下要自行调用 Scans.init(ServletContext)??

文档写好再Fix这个bug吧.

看来需要新增一个文档，讲讲 Scans

在什么地方调用Scans.init(ServletContext)呢？

Original comment by lein.x...@gmail.com on 13 Mar 2011 at 2:26

GoogleCodeExporter commented 9 years ago

你需要自己定义一个Servlet,并设置为启动即加载.这个servlet无�
��对应任何url,仅需要在init方法中调用Scans.init(ServletContext)

谢谢，问题已经解决，代码如下，不知道有没有问题
public class ScansServlet extends HttpServlet {

  @Override
  public void init() throws ServletException {
    super.init();
    Scans.me().init(this.getServletContext());
  }

}

就是这样写,并且load-on-start最好写1，其他servlet都写2或以上
