Grails：在Bootstrap代码的关闭中访问spring beans？ [英] Grails: Accessing spring beans in the destory closure of Bootstrap code?

问题描述

我正在寻找在我的grails项目的Bootstrap.groovy中的destroy关闭中访问一个bean。

我似乎无法访问servletContext ...？

解决方案

您可以使用该块代码从各处获得对applicationContext的引用（包括BootStrap的销毁关闭）：

  def ctx = org.codehaus.groovy.grails.web.context.ServletContextHolder.servletContext.getAttribute（org.codehaus.groovy.grails.web.servlet.GrailsApplicationAttributes.APPLICATION_CONTEXT）; 
  

获取对bean的引用就像 ctx.beanName <



这是一个小的util类（用Java编写），可以简化这个任务：



  import org.springframework.context.ApplicationContext; 
 import org.codehaus.groovy.grails.web.context.ServletContextHolder; 
 import org.codehaus.groovy.grails.web.servlet.GrailsApplicationAttributes; 
 
 public class SpringUtil {
 
 public static ApplicationContext getCtx（）{
 return getApplicationContext（）; 
 
 
 public static ApplicationContext getApplicationContext（）{
 return（ApplicationContext）ServletContextHolder.getServletContext（）。getAttribute（GrailsApplicationAttributes.APPLICATION_CONTEXT）; 
} 
 
 @SuppressWarnings（unchecked）
 public static< T> T getBean（String beanName）{
 return（T）getApplicationContext（）。getBean（beanName）; 
} 
 
} 
  

以及一个例子：

  def bean = SpringUtil.getBean（beanName）

I'm looking to access a bean in my destroy closure in the Bootstrap.groovy of my grails project. Any ideas on how to achieve this?

I seem to have no access to servletContext...?

解决方案

You can obtain a a reference to the applicationContext from everywhere (including the destroy closure of BootStrap) using that chunk of code:

def ctx = org.codehaus.groovy.grails.web.context.ServletContextHolder.servletContext.getAttribute(org.codehaus.groovy.grails.web.servlet.GrailsApplicationAttributes.APPLICATION_CONTEXT);

Getting a reference to a bean is as easy as ctx.beanName.

Here is a small util class (written in Java) that can simplify this task:

import org.springframework.context.ApplicationContext;
import org.codehaus.groovy.grails.web.context.ServletContextHolder;
import org.codehaus.groovy.grails.web.servlet.GrailsApplicationAttributes;

public class SpringUtil {

    public static ApplicationContext getCtx() {
        return getApplicationContext();
    }

    public static ApplicationContext getApplicationContext() {
        return (ApplicationContext) ServletContextHolder.getServletContext().getAttribute(GrailsApplicationAttributes.APPLICATION_CONTEXT);
    }

    @SuppressWarnings("unchecked")
    public static <T> T getBean(String beanName) {
        return (T) getApplicationContext().getBean(beanName);
    }

}

and an example:

def bean = SpringUtil.getBean("beanName")
