Maven+SSM框架搭建中（二）

**    思路：**

1.  **    配置maven环境；**
2.  **    设置maven的本地仓库，远程仓库(即中央仓库)；**  
    
3.  **    创建一个完整的maven项目 ;**  
    
4.  **    导包，即配置pom.xml ;**  
    
5.  **    添加框架整合的配置文件到src/main/resources下 ;**
6.  **    配置web.xml：主要是配置 编码过滤器，监听器，读取配置文件.**
7.  **    然后再配置一下项目的jdk环境**

*  **log4j.properties**
 *  **mybatis-config.xml**  
    
 *  **spring-mvc.xml**
 *  **spring-mybatis.xml**

千里之行，始于跬步。搭架子之前先配置下项目的运行环境。

![70][]

第一步和第二步主要是搭建maven环境，这个在上一章有介绍。配置完成后，进行下一步。

**3.1** 然后就是创建一个完整的maven项目。

打开eclipse,

右键 New  > Project > Maven Project > Next > Next >

![70 1][]

>  Next

![70 2][]

>   Finish

**3.2**  可以看到项目基本搭建完成，但这个时候的项目结构可能还存在些问题，一个标准的maven项目Java Resources下包含src/main/resources和src/test/java和src/main/java ，而创建出来的包只有src/main/resources,这里需要自己手动创建。（如果项目包含以上三个包可以跳过3.2直接到3.3）

解决方法这里介绍两种：

第一种比较简单：https://blog.csdn.net/qq\_29410905/article/details/80117436  [去看看][Link 1]

第二种麻烦些：

右键项目 > Build Path > Configure Build Path > Source 可以看到另外两个包资源丢失，这里删除再创建它们。

![70 3][]

Add Folder  > Create New Folder 创建刚刚删掉的包src/main/java和src/test/java >Finish > Apply > OK,这个时候就可以看到目录就比较完整了。

**3.3** 可以看到项目名的位置在报错，原因是工具生成的index.jsp页面不够完整，可以直接删掉。这个时候可以看到项目不报错了。

**4.1** 然后就是导包，通过pom.xml 导包，这里直接附上源码，基本上都相同，删减包看项目需求。

配置基本完成,要修改的就是连接数据库的信息。下面再配置一下项目的jdk环境。

右键项目 > Build Path > Configure Build Path > Libraries >

![70 4][]

>Edit

![70 5][]

>Finish >

![70 6][]

>Apply > Java Compiler >

![70 7][]

> Apply > 弹出的窗口选择Yes > Project Facets

![70 8][]

右键项目 > Maven > Update Project >OK

这个时候看一下Window > Show View > Markers 报错

![70 9][]

解决方式: 打开项目所在路径 .settings文件夹下的

![70 10][]

修改为

<?xml version="1.0" encoding="UTF-8"?>
    <faceted-project>
      <fixed facet="wst.jsdt.web"/>
      <installed facet="jst.web" version="3.0"/>
      <installed facet="wst.jsdt.web" version="1.0"/>
      <installed facet="java" version="1.8"/>
    
    </faceted-project>

右键项目 > Maven > Update Project >OK

等项目更新完毕基本OJK ，这个时候再看一下Markers报错

![70 11][]

没有报错，配置完成。这个时候已经配置完成，但是Tomcat运行项目会报错，原因是项目启动会去扫描mapper包，而咱们mapper包下什么也没有，可以看到控制台报错

Could not resolve resource location pattern [classpath:com/znkj/mapper/*.xml]: class path resource [com/znkj/mapper/] cannot be resolved to URL because it does not exist

很正常，走到这里报这个错就要恭喜你了，配置完成。下面就是给项目添加功能代码，具体下个章节介绍。
