# 问题现象： #

今天在启动一个新项目的主函数入口类（启动类）时无法启动，提示如下：

**Command line is too long. Shorten command line for SystemApplication or also for Spring Boot default configuration.**

--------------------

# 问题分析： #

根据提示信息可知大意为：**启动命令行太长！缩短 SystemApplication 的命令，或者也可以修改 Springboot 的默认配置。**

**所以只需要缩短启动命令即可！！！**

### **经过测试解决方法有两种：** ###

**1.修改 SystemApplication 的 Shorten command line，选择 JAR manifest 即可:**

**2.修改 Springboot 的默认配置：**

找到当前项目路径 **.idea\\workspace.xml**，找到标签 **<component name="PropertiesComponent">：**

在其下添加子标签 **<property /> 即可**:

### 总结： ###

我个人觉得默认配置的文件还是不要随便修改比较好，**因此我选择了方案一！！！**
