1、数据准备
SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for `admin`
-- ----------------------------
DROP TABLE IF EXISTS `admin`;
CREATE TABLE `admin` (
`a_id` int(11) NOT NULL AUTO_INCREMENT,
`a_name` varchar(20) NOT NULL,
`a_pwd` varchar(20) NOT NULL,
PRIMARY KEY (`a_id`)

-- ----------------------------
DROP TABLE IF EXISTS `category`;
CREATE TABLE `category` (

2、新建项目
3、完善项目结构
4、导入所需jar包

5、编写实体类
User:
package com.ssm.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.io.Serializable;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User implements Serializable {
private Integer id;
private String name;
private String pwd;
}
View Code
6、编写dao层
UserDao:
package com.ssm.dao;
import com.ssm.pojo.User;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository("userDao")
public interface UserDao {
void addUser(User user);
void deleteUser(Integer id);
void updateInfo(User user);
List queryAll();
User queryById(Integer id);
}
View Code
7、根据dao层编写xml映射配置文件
UserMapper.xml:
DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
insert into user(u_name,u_pwd) values (#{name},#{pwd})
View Code
8、编写Mybatis主配置文件(mybatis-config.xml)
DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<package name="com.ssm.pojo"/>
View Code
9、编写Spring全局配置文件(ApplicationContext.xml)
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
package="com.ssm">
class="com.mchange.v2.c3p0.ComboPooledDataSource">
class="org.mybatis.spring.SqlSessionFactoryBean">
class="org.mybatis.spring.mapper.MapperScannerConfigurer">
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
View Code
10、编写service层
IUserService:
package com.ssm.service;
import com.ssm.pojo.User;
import java.util.List;
public interface IUserService {
void addUser(User user);
void deleteUser(Integer id);
void updateInfo(User user);
List queryAll();
User queryById(Integer id);
}
View Code
UserService:
package com.ssm.service.impl;
import com.ssm.dao.UserDao;
import com.ssm.pojo.User;
import com.ssm.service.IUserService;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import java.util.List;
@Service("userService")
public class UserService implements IUserService {
@Resource
private UserDao userDao;
@Override
public void addUser(User user) {
userDao.addUser(user);
}
@Override
public void deleteUser(Integer id) {
userDao.deleteUser(id);
}
@Override
public void updateInfo(User user) {
userDao.updateInfo(user);
}
@Override
public List queryAll() {
return userDao.queryAll();
}
@Override
public User queryById(Integer id) {
return userDao.queryById(id);
}
}
View Code
11、spring整合Mybatis完成(测试)
import com.ssm.pojo.User;
import com.ssm.service.IUserService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import javax.annotation.Resource;
import java.util.List;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:ApplicationContext.xml")
public class UserTest {
@Resource
IUserService userService;
@Test
public void getAll() {
List users = userService.queryAll();
for (User user : users) {
System.out.println(user);
}
}
}
View Code
12、编写web.xml
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">

contextConfigLocation
classpath:ApplicationContext.xml

/
characterEncodingFilter
class>org.springframework.web.filter.CharacterEncodingFilter class>
characterEncodingFilter
/*
View Code
13、编写springmvc配置文件(springmvc.xml)
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context

http://www.springframework.org/schema/mvc
https://www.springframework.org/schema/mvc/spring-mvc.xsd">
default-servlet-handler/>
package="com.ssm.controller"/>
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
View Code
14、spring整合springmvc(ApplicationContext.xml引入springmvc.xml)
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<import resource="springmvc.xml"/>
package="com.ssm">
class="com.mchange.v2.c3p0.ComboPooledDataSource">
class="org.mybatis.spring.SqlSessionFactoryBean">
class="org.mybatis.spring.mapper.MapperScannerConfigurer">
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
View Code
15、编写controller层
UserController:
package com.ssm.controller;
import com.ssm.pojo.User;
import com.ssm.service.IUserService;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.annotation.Resource;
@RequestMapping("/user")
@Controller
public class UserController {
@Resource
IUserService userService;
@RequestMapping("getUserInfo")
public String test(Model model) {
User user = userService.queryById(1);
model.addAttribute("user", user);
return "success";
}
}
View Code
16、创建必要的测试页面
index.jsp:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
Title
点我测试!
View Code
success.jsp:
<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
Title
Name:${user.name}
PassWord:${user.pwd}
View Code
17、整合完成,测试喽!
18、晒上项目结构图
19、其他配置文件
数据库配置文件:
jdbc.driver=com.mysql.jdbc.Driver
#数据库地址
jdbc.url=jdbc:mysql://localhost:3306/booksys?useUnicode=true&characterEncoding=utf8
#用户名
jdbc.username=root
#密码
jdbc.password=123456
#最大连接数
c3p0.maxPoolSize=30
#最小连接数
c3p0.minPoolSize=10
#关闭连接后不自动commit
c3p0.autoCommitOnClose=false
#获取连接超时时间
c3p0.checkoutTimeout=10000
#当获取连接失败重试次数
c3p0.acquireRetryAttempts=2
View Code
log4j日志配置文档:
log4j.rootLogger=debug,stdout, R
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
# Pattern to output the caller"s file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
