maven 创建Java web项目

第一步创建项目

 

 

 然后 切换到Navigator视图 (在window--> Show View 下可以找到)

在 setings 下面设置项目的一些属性 (主要是jdk编译版本 web版本)

右键properties检查下Web Deployment Assembly设置有没有问题

如果WEB-INF下面缺少lib文件 新建一个并 右键Build Path

编写 pom.xml  加载jar包 根据项目需求 右键 Run as-> maven-installer

 注意(如果配置完運行Tomcat一直報錯,配置文件檢查后沒問題,可能是jar包衝突)
