用STS和Maven的方式创建一个JavaWeb项目

一.创建项目

1.Eclipse中用Maven创建项目，选maven-archetype-webapp，如下图：

创建好项目后，目录如下：

至此，项目已经创建完毕，下边是配置。关键所在！！！

二.项目配置

1.添加Source Folder

Maven规定，必须创建以下几个Source Folder

src/main/resources

src/main/java(如果直接不能建，可以先建src/main/java1,然后在把java1改成java)

src/test/resources

src/test/java

添加以上的Source Folder

创建好后的目录如下：

2.配置Build Path

3.设定4个文件夹的输出Output folder，双击修改

分别修改输出路径为

src/main/resources　　　对应　　target/classes
src/main/java　　　　　　对应　　target/classes
src/test/resources　　　对应　　target/test-classes
src/test/java　　　　　　对应　　target/test-classes

5.设定Libraries

或者设置maven的pom.xml文件

 1 <properties>
 2         <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
 3     </properties>
