我使用的IDE是Idea，其本身也是运行在jvm上的，我又尝试修改了其 vmoptions 配置文件(在IDEA安装目录的bin目录下的idea64.exe.vmoptions)，修改如下所示的参数: 我又详细看了下报错的信息，最开始报错的是关于数据库的部分，可能是数据库连接等方面出了问题，尝试处理了下，确实启动就不再报错了。 这类启动时疑似上述内存泄漏的报错，大多是对应的服务启动失败。我这里就是数据库服务启动失败了，由于使用了没有授权的db |
一开始我的重点都放在To prevent a memory leak, This is very likely to create a memory leak，因为是启动的时候报错，所以怀疑是jvm内存大小不够，在启动的时候添加参数: -Xms,-Xmx,但是启动的时候仍旧报错。
也可以在idea的操作界面上进行设置，如下图所示: 
但是最终都没有效果。【本文地址】
