## **一、如图所示进行创建，一路next ** ##

## **![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNTcwNjU4_size_16_color_FFFFFF_t_70][]** ##

## ** ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNTcwNjU4_size_16_color_FFFFFF_t_70 1][]** ##

## **![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNTcwNjU4_size_16_color_FFFFFF_t_70 2][]** ##

## **![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNTcwNjU4_size_16_color_FFFFFF_t_70 3][]** ##

## **![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNTcwNjU4_size_16_color_FFFFFF_t_70 4][]** ##

## **二、创建完成后的项目结构（拉红线的是我写的测试，大家略过） ** ##

## **![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNTcwNjU4_size_16_color_FFFFFF_t_70 5][]** ##

## **三、启动试试(右键run，或者唯一的java类内的小绿三角点击启动，或者使用快捷键)** ##

## **![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNTcwNjU4_size_16_color_FFFFFF_t_70 6][]** ##

## **五、成功后的日志（经典Spring拼图，需要关注的是默认是8080端口）** ##
