IntelliJ IDEA默认的Output输出缓存区大小只有1024KB，超过大小限制的就会被清除，而且还会显示【too much output to process】，可通过如下配置界面进行修改Override console cycle buffer size（Settings→Editor→General→Console），单位为KB

如果需要禁用缓存区大小限制就需要修改配置文件idea.properties

|---------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 | 配置文件中原有设置： #--------------------------------------------------------------------- # This option controls console cyclic buffer: keeps the console output size not higher than the specified buffer size (Kb). # Older lines are deleted. In order to disable cycle buffer use idea.cycle.buffer.size=disabled #--------------------------------------------------------------------- idea.cycle.buffer.size=1024 |

修改配置如下所示：

|-----------|-----------------------------------------| | 1 | idea.cycle.buffer.size=disabled |

禁用后的界面如下所示：
