Maven+SSM框架搭建【spring+springmvc+mybatis】
本案例用到：ssm【spring+springmvc+mybatis】框架
数据库：mysql (推荐使用mysql 或者 sqlserver 。oracle太大，一般大型项目才会用到)
开发工具：idea (myEclipse也行)
项目管理工具：maven
(1) Maven设置
Maven是一个项目管理工具，本项目中主要用来对jar包的管理
File – Settings -- Maven
Maven中conf 中 settings.xml设置
(2) 创建maven项目
File—New--Project
接着下一步，这里需要注在Properties中添加一个参数 archetypeCatalog=internal，不加这个参数，在maven生成骨架的时候将会非常慢，有时候直接卡住。
创建maven项目结果
为项目添加java包
File-- Project Structure---Modules
将java 文件变成source文件夹,参考
http://www.jianshu.com/p/099eeca28c0f
(3) pom.xml设置

设置成果后，刷新maven，发现下载到所有jar包，如下图
(4) spring配置文件设置：

(5) MVC框架设置
5.1 M层：用于放类比如User类
package com.fzu.edu.model;
import java.io.Serializable;
import java.util.Date;
/**
* Created by bianbian on 2017/10/25.
*/
public class User implements Serializable {
private Long id;
private String userName;
private String userPhone;
private String userEmail;
private String userPwd;
private String pwdSalt;
private Date createTime;
private Date modifyTime;
private Short isDelete;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getUserPhone() {
return userPhone;
}
public void setUserPhone(String userPhone) {
this.userPhone = userPhone;
}
public String getUserEmail() {
return userEmail;
}
public void setUserEmail(String userEmail) {
this.userEmail = userEmail;
}
public String getUserPwd() {
return userPwd;
}
public void setUserPwd(String userPwd) {
this.userPwd = userPwd;
}
public String getPwdSalt() {
return pwdSalt;
}
public void setPwdSalt(String pwdSalt) {
this.pwdSalt = pwdSalt;
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
public Date getModifyTime() {
return modifyTime;
}
public void setModifyTime(Date modifyTime) {
this.modifyTime = modifyTime;
}
public Short getIsDelete() {
return isDelete;
}
public void setIsDelete(Short isDelete) {
this.isDelete = isDelete;
}
}
5.2 Dao层：是链接数据库的接口层
package com.fzu.edu.dao;
import com.fzu.edu.model.User;
import org.springframework.stereotype.Repository;
import java.util.List;
/**
* Created by bianbian on 2017/10/25.
*/
@Repository
public interface UserDao {
List<User> selectAllUser();
}
5.3 Service层：是控制层与Dao层之间的桥梁，主要用于逻辑的编写
5.4 控制层：是前段与后台的连接口
package com.fzu.edu.controller;
import com.fzu.edu.model.User;
import com.fzu.edu.service.UserService;
import com.fzu.edu.service.impl.UserServiceImpl;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import java.util.List;
/**
* Created by bianbian on 2017/10/25.
*/
@Controller
@RequestMapping("/user")
public class UserController {
private Logger log = Logger.getLogger(UserController.class);
@Resource
private UserService userService;
@RequestMapping("/showUser")
public String showUser(HttpServletRequest request, Model model){
log.info("查询所有用户信息");
List<User> userList = userService.getAllUser();
model.addAttribute("userList",userList);
return "showUser";
}
}
(6) jdk设置
(7) tomcat设置
(8) 数据库设置：本案例以mysql为例
mysql搭建过程：自行百度
sql语言：
SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for `t_user`
-- ----------------------------
DROP TABLE IF EXISTS `t_user`;
CREATE TABLE `t_user` (
`id` bigint(11) NOT NULL auto_increment,
`user_name` varchar(255) default NULL COMMENT '用户名',
`user_phone` varchar(20) default NULL COMMENT '手机号',
`user_email` varchar(255) default NULL COMMENT '邮箱地址',
`user_pwd` varchar(32) default NULL COMMENT '加盐后用户密码',
`pwd_salt` varchar(6) default NULL COMMENT 'MD5盐',
`create_time` datetime default NULL COMMENT '创建时间',
`modify_time` datetime default NULL COMMENT '最后修改时间',
`is_delete` tinyint(4) default NULL COMMENT '是否删除，0-未删除；1-已删除',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8 COMMENT='用户登录表';
-- ----------------------------
-- Records of t_user
-- ----------------------------
INSERT INTO `t_user` VALUES ('1', '卞', 18120861228, '631951562@qq.com', '05126a423a9379d529e4ee61a212fa55', 'KJUYT5', '2017-10-25 23:38:56', '2017-10-25 23:39:09', '0');
INSERT INTO `t_user` VALUES ('2', '李', 18120861228, '631951562@qq.com', '98bd3a1bebde01ad363d3c5a0d1e56da', '656JHU', '2017-10-25 23:39:01', '2017-10-25 23:39:13', '0');
INSERT INTO `t_user` VALUES ('3', '管', 18120861228, '631951562@qq.com', '5470db9b63c354f6c8d628b80ae2f3c3', '89UIKQ', '2017-10-25 23:39:05', '2017-10-25 23:39:16', '0');
