创建新工程

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2FiY18xMjM0NTZfX18_size_16_color_FFFFFF_t_70][]

选择maven，勾选create from archetype,选择webapp,下一步

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2FiY18xMjM0NTZfX18_size_16_color_FFFFFF_t_70 1][]

填写groupId,artifactId,下一步，一直下一步，最后finish

![20190323160002337.png][]

等到完成之后，可以看到下列项目结构

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2FiY18xMjM0NTZfX18_size_16_color_FFFFFF_t_70 2][]

接下来看一下我们最后应该完成的包结构，如下图

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2FiY18xMjM0NTZfX18_size_16_color_FFFFFF_t_70 3][]

根据以上增加包，以及文件

其中pom.xml为
