搭建maven+spring+mybatis工程

一、maven 命令搭建web项目

可以参考我之前的一篇博文maven快速入门

　1、搭建web工程

mvn archetype:generate -DgroupId=com.yuanmeng.springdemo -DartifactId=spring-mybatis -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

　2、pom配置

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

　3、切换到工程根目录下，执行 mvn eclipse:eclipse。将maven工程转为eclipse工程，然后在eclipse导入工程

二、创建表

 登录 mysql -uroot -p
 use testdb
 创建表
 create table user_info(
　　id int(16) not null primary key auto_increment,
　　name varchar(32) not null,
　　password varchar(32) not null
);

三、自动生成dao、do、mapper xml配置

可以参考我之前的一篇博文mybatis-generator-core自动生成do、mapping、dao 代码

四、代码结构

dao 

public interface UserInfoMapper {
    int deleteByPrimaryKey(Long id);

    int insert(UserInfo record);

    int insertSelective(UserInfo record);

    UserInfo selectByPrimaryKey(Integer id);

    int updateByPrimaryKeySelective(UserInfo record);

    int updateByPrimaryKey(UserInfo record);
}
