spring+springmvc+mbatis+maven+velocity构建javaEE项目

开发工具eclipse(Mars) jdk版本1.7 maven版本：3.2.1步骤：1.1创建maven项目1.2.红色框中的选中1.3.由于是web项目，所以选择war。其他的参考maven的知识详解1.4.pom.xml报了这个错，web.xml is missing and <failOnMissingWebXml> is set to true这是在项目中缺少web.xml文件添加web.xml即可项目结构如图****注：看不懂的同学可以看看maven的相关知识1.5.接下来是配置pom文件详细介绍在pom文件里面2.1.spring集成mybatis在web.xml文件中配置spring监听器和编码过滤器2.2.spring集成mybatis的配置文件地址2.3编写相应的包

2.4.相应的类讲解2.4.1.Userpackage com.ssm.entities;public class User {private Integer id;private String userName;private String password;private Integer age;}**相应的get set省略2.4.2 UserMapperpackage com.ssm.mapper;import java.util.List;import com.ssm.entities.User;public interface UserMapper {int deleteById(Integer id);int insert(User user);User getUserById(Integer id);int updateById(User
