希望大家帮忙找找内存溢出问题原因

Answer 1

启动程序的时候加上参数java -Xms1024m -Xmx1024m 1024是最小和最大虚拟机内存，设到不报这个错误即可。

Answer 2

MyEclipse中的工具条中Run->Open run dialog->Arguments
在VM arguments中加入
-Xms256m
-Xmx512m

-Xmx为最大设置,不要超过物理内存的80%
-Xms为初始设置

Answer 3

光有错误代码，没原始代码，怎么知道你哪错，还有这是仕么时候报的错，是执行时，还是启动时

Answer 4

java.lang.OutOfMemoryError: Java heap space

内存不足!

Answer 5

程序代码呢
