Spring+SpringMVC+mybatis+5.7MySQL项目搭建
SSM+5.7MySQL项目搭建
- 1. 创建maven项目
- 2. 配置项目
- 3. 配置SpringMVC
- 4.引入log4j.properties
- 5. 测试springMVC
- 6. 引入mybatis
- 7.测试mybatis
1. 创建maven项目
jdk环境1.8
使用IDE创建maven项目,这里选用官网上的STS
选择创建web项目
定义号group id和artifact id之后点击finish即可
2. 配置项目
单机建好的项目, ALT +Enter 快捷键进入配置
当出现 cannot change version of project facet Dynamic Web Module to 3.1时,先暂时关闭此界面,点击该下拉框，选择filters，按照下图操作。
之后项目目录下会出现.settings文件, 修改该xml
可能会出现这种错误
dynamic web moudule 3.1 requires java 1.7 or newer
这种问题是可以在pom文件build中添加该条信息
<plugins>
<plugin>
<groupId>org.apache.maven.pluginsgroupId>
<artifactId>maven-compiler-pluginartifactId>
<version>2.3.2version>
<configuration>
<source>1.8source>
<target>1.8target>
configuration>
plugin>
plugins>
然后右击项目–>maven–>update project即可
引入相应的包，这里先引入spring核心包，mybatis核心包，日志等pom文件如下

3. 配置SpringMVC
创建spring-mvc.xml配置文件
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<context:annotation-config/>
<context:component-scan base-package="com.indi"/>
<mvc:annotation-driven/>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
bean>
beans>
配置web.xml文件
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

web-app>
创建controller
package com.indi.controller;
import javax.servlet.http.HttpSession;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class TestController {
@RequestMapping("/index")
public String index() {
return "fail";
}
@RequestMapping("/index2")
public String index2() {
return "index2";
}
}
创建index2.jsp
index2
4.引入log4j.properties
log4j.rootLogger=DEBUG,stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
#log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%-5p]%d{yyyy-MM-dd HH:mm:ss} %l: %m %x %n
#日志文件输出到指定位置
log4j.appender.logfile.File=D:/project/wsglxt/logs/log.txt
log4j.appender.logfile.Append=true
log4j.appender.logfile.MaxFileSize=5MB
log4j.appender.logfile.MaxBackupIndex=30
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=[%-5p]%d{yyyy-MM-dd HH:mm:ss} %l: %m %x %n
log4j.logger.org.springframework=ERROR
log4j.logger.org.springframework.web=DEBUG
log4j.logger.org.springframework.web.servlet.handler=debug
log4j.logger.org.mybatis=INFO
log4j.logger.org.apache.ibatis.logging.jdbc=DUBUG
log4j.logger.org.apache.ibatis.logging.jdbc= debug
log4j.logger.com.github=ERROR
5. 测试springMVC
这里使用Tomcat7 插件进行运行，右击项目，debug as —》maven build， 进行以下配置即可
然后在浏览器中输入网址http://localhost:8080/ssm1/，显示如下
6. 引入mybatis
在resource目录下创建jdbc.properties文件
jdbc.url=jdbc:mysql://localhost/ssm_test?useSSL=false&serverTimezone = UTC&
jdbc.driverClassName=com.mysql.cj.jdbc.Driver
##mysql5.7以下用此驱动
#jdbc.driverClassName=com.mysql.jdbc.Driver
#jdbc.url=jdbc:mysql://127.0.0.1/3306/information_schema?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
jdbc.username=*****
jdbc.password=******
jdbc.initialSize=10
jdbc.minIdle=10
jdbc.maxActive=50
jdbc.maxWait=60000
j
创建spring-mybatis.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
bean>
<tx:annotation-driven transaction-manager="transactionManager" />
beans>
7.测试mybatis
创建实体类
public class User {
private Integer id;
private String userName;
private String sex;
private Integer age;
private String email;
创建dao
package com.indi.dao;
import java.util.List;
import org.springframework.stereotype.Repository;
import com.indi.entity.User;
@Repository
public interface UserDao {
List selectAll();
int deleteById(int id);
}
创建mapper文件
<mapper namespace="com.indi.dao.UserDao">
<resultMap type="com.indi.entity.User" id="userResultMap">
<id column="id" property="id"/>
<result column="user_name" property="userName"/>
<result column="sex" property="sex"/>
<result column="age" property="age"/>
<result column="email" property="email"/>
resultMap>
<select id="selectAll" resultMap="userResultMap">
select id,user_name,sex,age,email from users
select>
<delete id="deleteById" parameterType="java.lang.Integer">
delete from users where id=#{id}
delete>
mapper>
执行以下sql
DROP TABLE IF EXISTS users ;
CREATE TABLE users (
`id` INT(11) NOT NULL AUTO_INCREMENT,
`user_name` VARCHAR(40) NOT NULL,
`sex` VARCHAR(255) NOT NULL,
`age` INT(4) NOT NULL,
`email` VARCHAR(60) ,
PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
INSERT INTO users (user_name,sex,age,email) VALUES ('张三','男',18,'[email protected]'),('李四','男',19,'[email protected]');
SELECT id,user_name,sex,age,email FROM users;
进行Junit测试
package com.indi.user.test;
import java.util.List;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import com.indi.dao.UserDao;
import com.indi.entity.User;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath*:spring-*.xml")
public class UserTest {
@Autowired
UserDao userDao;
@Test
public void testUserDao() {
List users = userDao.selectAll();
users.forEach(user->System.out.println(user));
}
}
可以查看输出结果
整合SSM到此结束!
