maven工程建立和SSM（springMVC+spring+mybatis）整合

2022-04-13 08:45:40 浏览数 (1)

1.环境：

maven 版本：3.5.1

ecelipse mars.2

JDK : jdk1.8.0_45

tomcat : apache-tomcat-8.0.0-RC1

2. 建maven 工程：

new -> other -> Maven Project-> next-> 勾选 Create a simple project -> next ->

Group Id 填 包名 、Artifact Id 填 工程名、packaging 选 war , 其余5个不填。 -> finish 。

工程上有个小红叉 ,解决方案：

在工程上右键-> javaEE tools -> Generate Deployment Descriptor Stub。

额外配置：工程上右键 -> properties -> Project Facets -> Dynamic Web Module 选3.1 、java 选 1.8 。

3.ssm工程：

model、mapper、conreoller... 代码写在src/main/java 文件夹下。

applicationContext.xml、log4j.properties、

dbconfig.properties、spring-mybatis.xml、spring-servlet.xml放在src/main/resources文件夹下。

在如图选中的位置（src/main/resources）右键 new ->other -> Spring文件下选择Spring Bean Configuration File ->next

->取个名字 -> next -> 选择需要的项，可选择下面对应不同版本。不选版本默认为最新版本。-> finish

这样就可以自动生成文件头，如下图：

4.整合：
