eclipse创建maven项目

Maven项目 创建

1.鼠标右键

2.选择maven项目

3.选择项目存放路径和名称

4.过滤器里输入web。我们要创建一个web工程

5.新生成的工程默认没有src/main/java这样的目录。web.xml里也是2.3的。

6.点项目鼠标右键

7.再次把这两项勾选上，然后点击Further ocnfiguration availiable

8.把默认的编译路径remove掉（这个路径不正确，必须删掉，不然报错）

换成src/main/java和src/main/resources. 输出路径改为target/classes

 

这一步结束后，我们的src/main/java目录也自动出现了。

 

 

 

 

 9.这时候项目结构已经完整了，但是有报错，选中项目，鼠标右键选择

Properties------->java build Path

 

添加jar包

在pom.xml中添加一下配置

项目启动报以下错是因为在tomcat下lib中jar没有加载上

 

手动配置以下加载jar包
