背景:我有一个使用JSP的Web项目.IDE是Eclipse.tomcat的配置是:资源发生变化时自动发布,发布间隔为"1秒".
classes文件夹中的属性文件,用于保存一些设置.它也可以由servlet动态修改.修改操作由JSP中的save按钮触发.
问题:经过几次保存操作后,Tomcat自带了java.lang.OutOfMemoryError: PermGen space.

Exception in thread "http-bio-8080-exec-3" java.lang.OutOfMemoryError: PermGen space
我之前也运行了本教程中的代码,并打开了一些blob文件,但我认为这不会导致问题,因为即使在关闭所有内容并重新启动计算机之前,此错误仍然存在. .再次在服务器上运行以获取代码.
我搜索了错误并阅读有关内存泄漏的帖子,例如将大量文件完全加载到内存中而不是使用输入流等.但是当我分析应用程序中的所有代码时,我找不到任何大的变量.我发布下面的代码.如果我还有其他任何内容可以帮助您找到问题,请告诉我.
谁能告诉我内存泄漏的位置？
这是Link Controller:
@Controller
public class LinkController {
@RequestMapping(value="/")
public ModelAndView mainPage() {return new ModelAndView("home");}
@RequestMapping(value="/index")
public ModelAndView indexPage() {return new ModelAndView("home");}
}
这是团队控制器:
@Controller
@RequestMapping(value="/team")
public class TeamController {
@Autowired
private TeamService teamService;
@RequestMapping(value="/add", method=RequestMethod.GET)

ModelAndView modelAndView = new ModelAndView("add-team-form");
modelAndView.addObject("team", new Team());
return modelAndView;
}
