Maven-使用Eclipse创建一个Maven风格的SSM项目

创建maven web项目

File->New->Other->Maven->Maven Project



设置项目目录

默认即可



选择Archetype

选择 maven-archetype-webapp



设置GroupId和Artifact Id

设置GroupId和Artifact Id,分别是com.how2java和ssm。

后续配置也是用的这个，所以照着做，别自作聪明改其他的，不然后面走不通



项目截图

此时项目就创建好了，不过还会报错，接着做后续的一系列操作



创建java 源代码目录

在上一步的截图中可以发现，没有地方存放java源文件，这个时候就需要按照如下步骤做：

右键项目->属性->Java Build Path->Libraries->Edit->Workspace default 

JRE(jdk8)->Finish



java源文件目录创建好了



pom.xml

接着复制粘贴pom.xml为下面的代码。 粘贴之后，jsp本来的报错就消失了，不过出来一个新的问题，要求通过Maven更新项目。

右键项目->Maven->Update Project，会弹出一个对话框，点击Ok，这个问题就消失了。

web.xml

首先覆盖web.xml

把下载下来的xxx/ssm/WebContent/WEB-INF/web.xml

复制到当前的 ssm/src/main/webapp/web.xml这里



jsp 目录

接着复制jsp目录。 

千万不要复制lib目录



配置文件

把3个配置文件复制到ssm/src/main/resources下面



java源代码

把java源代码复制到src/main/java下



关于Category.xml

按照maven ssm项目风格来说，这个文件本应该放在Resource目录的mapper文件夹下，但是这么做还要修改配置信息，为了避免问题复杂话，而且考虑到即使放在当前位置也是可以正常工作的，所以就暂时不修改它的位置了。



启动Tomcat

右键点击项目，点击Run As -> Run on Server 启动Tomcat
访问测试地址

访问如下测试地址：

http://localhost:8080/ssm/listCategory
