jfinal spring插件的问题

@JFinal 你好,想跟你请教个问题:

由于使用shiro来做权限控制,另外考虑到spring是其他框架的粘合剂,故考虑把spring放到jfinal中。

当在配置好后出现了问题,由于我在spring的bean中使用了activerecord查询数据库,但是错误显示,当spring加载bean的时候,activerecord以及其他的一些plugin是没有加载完成的,故导致无法使用,故这种情况下是否可以在afterJFinalStart中单独加载其他的plugin,比如说为了解决上述问题,把springplugin放到afterJFinalStart中加载?

我的web.xml applicationcontext.xml代码如下:

web.xml

你的数据源是什么? 建议使用spring管理数据源,方便spring的事务管理,然后再将spring的数据源注入到jfinal的AR中

    ActiveRecordPlugin 是可以独立动行的插件,所以可以在很早的时候就 start() 起来,楼主碰到的问题,只需要让 ActiveRecordPlugin 在 SpringPlugin 之前启动就可以,所以在 configPlugin(Plugins me) 方法中让 ActiveRecordPlugin 先添加到 Plugins me 对象中就可以:

public void configPlugin(Plugins me) {
  ActiveRecord arp = new ActiveRecordPlugin(...);
  ......
  me.add(arp);

  SpringPlugin sp = new SpringPlugin(...);
  me.add(sp);
}
  另外 ActiveRecordPlugin 插件还可以在 configConstant(Constants me) 中创建并 start(),这样能将加载时间提到更靠前。

看情况不像是先后顺序问题

因为我尝试

我尝试把  SqlInXmlPlugin 放前面,但是在bean中使用SqlKit的时候也有空异常me.add(new SqlInXmlPlugin());
me.add(new SpringPlugin());

    楼主的代码显示是用了 ContextLoaderListener   加载的 Spring,这样就导致了Spring 的初始化是在整个 JFinal 初始化之前就初始化了 spring,而spring 初始化中又引用了 jfinal 的 activerecord,解决办法至少两个:

1:在 Spring 中的某个适合的点手动创建 ActiveRecrordPlugin 并调用其 start(),而不要在 jfinal 中初始化 ActiveRecordPlugin

2:在 jfinal 中初始化 spring,而不要在 web.xml 中配置 spring

感谢JFinal,问题解决了,把web.xml中的

<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
去掉即可
