总结如何搭建一个项目
1、新建一个Maven项目
2、可能新建之后会有错，右键Deployment
Descriptor: note, 选择Generate
Deployment Descriptor Stub
3、使用maven仓库导包
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc-portlet</artifactId>
<version>3.2.8.RELEASE</version>
</dependency> <dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.8.5</version>
</dependency> <dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.8.5</version>
</dependency> <dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.8.5</version>
</dependency> <dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>3.2.8.RELEASE</version>
</dependency> <dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.4.0</version>
</dependency> <dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.3.1</version>
</dependency> <dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.38</version>
</dependency> <dependency>
<groupId>commons-dbcp</groupId>
<artifactId>commons-dbcp</artifactId>
<version>1.4</version>
</dependency> </dependencies>
dependencies
3.1、查看一下下载的包
如果maven的包迟迟不下载，就右键项目，选择maven – UpdateProject
4、 为项目指定tomcat运行环境
右键项目 – Properties – Targeted Runtimes
5.在下面server的tomcat服务器中添加项目
6 、在src/main/resources下添加两个文件夹
7 、 Spring配置文件
先将原项目的两个配置文件 spring-service.xml和 spring-mybatis.xml 复制过来
将spring-service.xml 改名为spring-web.xml,因为这样更合适一点
spring-mybatis.xml注意改一下文件里的包名，其他的关于mybatis的不用改
spring-web.xml如下：
<?xml version="1.0" encoding="UTF-8"?>

spring-web.xml

8 、 相应的在src/main/java下添加两个包
9 、 新建一个Servlet
可以查看src/main/webapp/WEB-INF下的web.xml，验证一下
10 、 将Tomcat 发布 然后 运行！
