手把手搭建SSM框架
搭建一个简单的SSM框架,分享给大家,以后自己也可以拿出来用
1.用maven项目管理工具搭建一个简单SSM的demo:工具Eclipse,Mysql-5.5,Tomcat-7.0,Maven-3.0,jdk-1.8
(1) 新建一个动态web项目,当然也可以建一个Java普通项目,
(2)Dynamic Web Project
选择好你需要设置的配置和tomcat版本,点击下一步
可以添加一个resources文件夹,方便后面我们存放各种配置文件。点击下一步记得把这个勾选上,是后面需要设置的一个web.xml文件。
(3)这样我们就创建好了一个动态Web项目
(4)右击项目名,选择下面的Configure==>Convert to Maven Project
点击完成就行,加入Maven项目管理工具能使我们在做项目省很多心思。
我们需要在这个pom.xml写我们需要的引入依赖包及版本,大家可以上maven仓库查找需要的版本http://mvnrepository.com/
(5)依赖包

3.写入环境
(1)jdbc.properties
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm2?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&failOverReadOnly=false&maxReconnects=10
jdbc.username=root
jdbc.password=123456
(2)mybatis-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 配置全局属性 -->
<settings>
<!-- 使用jdbc的getGeneratedKeys获取数据库自增主键值 -->
<setting name="useGeneratedKeys" value="true" />
<!-- 使用列别名替换列名 默认:true -->
<setting name="useColumnLabel" value="true" />
<!-- 开启驼峰命名转换:Table{create_time} -> Entity{createTime} -->

</configuration>
后面我是将spring配置文件分为3个部分,方便我们管理
(3)spring-dao.xml

4.创建项目骨架
基本的结构,还可以分mapper包,放mybatis的映射文件
(1)User.java实体类
package cn.ssm.entity;
public class User {
private Integer id;
private String code;
private String password;
private String name;
private String phone;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String toString() {
return "User [id=" + id + ", code=" + code + ", name=" + name + ", phone=" + phone + "]";
}
}
(2)UserDao.java用户接口
package cn.ssm.dao;
import cn.ssm.entity.User;
public interface UserDao {
void login(String code,String password);//登陆
int add(User user);//注册
int queryAllById(int id);//查询
}
(3)UserDao.xml UserMapper
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.smm.dao.UserDao">
<!-- 目的:为dao接口方法提供sql语句配置 -->
<!-- 登陆验证 -->
<select id="login" parameterType="map">
SELECT
code,
password
FROM
user
where
code=#{code}
and
password=#{password}
</select>
<!-- 查询 -->
<select id="queryAllById" resultType="User" parameterType="int">
SELECT
id,
code,
name,
phone,
FROM
user
WHERE
id=#{id}
</select>
<!-- 添加用户 -->
<insert id="add" resultType="int" parameterType="User">
insert into
user(
code,
password,
name,
phone)
values(
code=#{code},
password=#{password},
name=#{name},
phone=#{phone})
</insert>
</mapper>
(4)UserService.java
package cn.ssm.service;
import cn.ssm.entity.User;
public interface UserService {
/**
* 登录验证
* @param account 登录账号
* @param userPassword 密码
* @return validate true通过 false未通过
* @throws Exception
*/
User login(String code, String password) throws Exception;
/**
* 注册
* @param user
*/
int add(User user)throws Exception;
/**
* ID查询
* @param id
* @return
* @throws Exception
*/
User queryById(int id)throws Exception;
}
(5)UserServiceImpl.java
package cn.ssm.service;
import org.springframework.beans.factory.annotation.Autowired;
import cn.ssm.dao.UserDao;
import cn.ssm.entity.User;
public class UserServiceImpl implements UserService {
@Autowired
UserDao userDao;
@Override
public User login(String code, String password) throws Exception {
return userDao.login(code, password);
}
@Override
public int add(User user) throws Exception {
return userDao.add(user);
}
@Override
public User queryById(int id) throws Exception {
return userDao.queryById(id);
}
}
(6)UserCtroller.java
package cn.ssm.web;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import cn.ssm.entity.User;
import cn.ssm.service.UserService;
@Controller
@RequestMapping("/user")
public class UserCtroller {
@Autowired
UserService userService;
@RequestMapping("login")
public String login(String code, String password, Model model) throws Exception {
System.out.println("用户登陆" + code + password);
userService.login(code, password);
model.addAttribute("sg", "登陆成功");
return "show";
}
@RequestMapping("add")
public String add(User user, Model model) throws Exception {
System.out.println("用户注册" + user.getCode() + user.getPassword());
int addUser = userService.add(user);
model.addAttribute("sg", "注册成功");
if (addUser == 1) {
return "login";
}
return null;
}
@RequestMapping("query")
public String queryById(int id, Model model) throws Exception {
System.out.println("查询id" + id);
userService.queryById(id);
model.addAttribute("sg", "查询结果");
return "show";
}
}
