把InitBloggerData中第二个方法中的内容注释掉

[wzunique]

具体怎么弄？

[weenhall]

找到InitBloggerData这个类，第二个方法中的内容注释掉。跑不起来是因为该方法使用数据库时内存溢出

[wzunique]

具体是注释哪里？

package ssm.blog.listener;

import java.util.List;

import javax.servlet.ServletContext; import javax.servlet.ServletContextEvent; import javax.servlet.ServletContextListener;

import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; import org.springframework.stereotype.Component;

import ssm.blog.entity.Blog; import ssm.blog.entity.BlogType; import ssm.blog.entity.Blogger; import ssm.blog.entity.Link; import ssm.blog.service.BlogService; import ssm.blog.service.BlogTypeService; import ssm.blog.service.BloggerService; import ssm.blog.service.LinkService;

@Component public class InitBloggerData implements ServletContextListener, ApplicationContextAware {

private static ApplicationContext applicationContext;

public void contextInitialized(ServletContextEvent sce) {
	System.out.println(applicationContext);
	//先获取servlet上下文
	ServletContext application = sce.getServletContext();
	
	//根据spring的上下文获取bloggerService这个bean
	BloggerService bloggerService = (BloggerService) applicationContext.getBean("bloggerService");
	//获取博主信息
	Blogger blogger = bloggerService.getBloggerData();
	//由于密码也获取到了，比较敏感，我们也不需要这个，所以把密码清空掉
	blogger.setPassword(null);
	//将博主信息存入application域中
	application.setAttribute("blogger", blogger);
	
	//同上，获取友情链接信息
	LinkService linkService = (LinkService) applicationContext.getBean("linkService");
	List<Link> linkList = linkService.getLinkData(); 
	application.setAttribute("linkList", linkList);
	
	//同上，获取博客类别信息
	BlogTypeService blogTypeService = (BlogTypeService) applicationContext.getBean("blogTypeService");
	List<BlogType> blogTypeList = blogTypeService.getBlogTypeData();
	application.setAttribute("blogTypeList", blogTypeList);
	
	//同上，获取博客信息，按照时间分类的
	BlogService blogService = (BlogService) applicationContext.getBean("blogService");
	List<Blog> blogTimeList = blogService.getBlogData();
	application.setAttribute("blogTimeList", blogTimeList);
}

public void contextDestroyed(ServletContextEvent sce) {
	// TODO Auto-generated method stub
	
}

public void setApplicationContext(ApplicationContext applicationContext) 
		throws BeansException {
	InitBloggerData.applicationContext = applicationContext;
}

}

[weenhall]

contextInitialized这个方法里面的内容注释掉

[wzunique]

还是没有用 HTTP Status 404 - /

type Status report

message /

description The requested resource is not available.

Apache Tomcat/7.0.64

[wzunique]

这个java1234的blog你试成功了吗？

[weenhall]

可以运行啊，你没调试好吧

[changjiliao]

突然发现这个没有注册功能
