石可破也，而不可夺坚；丹可磨也，而不可夺赤。

一、创建工程

1.1创建Maven工程

---

---

1.2工程命名

---

1.3检查&配置本地Maven路径

---

二、SSM整合

2.1导入相关依赖

<dependencies><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>5.2.10.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>5.2.10.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>5.2.10.RELEASE</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.5.13</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.3.3</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.32</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.2.16</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.13</version><scope>test</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>3.1.0</version><scope>provided</scope></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.15.0</version></dependency></dependencies>

2.2添加tomcat插件（可选）

<build><plugins><plugin><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><version>2.2</version><configuration><!--设置端口号及访问路径--><port>80</port><path>/</path></configuration></plugin></plugins></build>

2.3添加配置类

• 项目包结构：

---

---

2.3.1添加Spring配置类

• 创建包结构com.practice.config，创建SpringConfig类

package com.practice.config;import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.context.annotation.PropertySource;/*** @Author YJ* @Date 2023/8/13 16:50* Description:Spring配置类*/
@Configuration//表明配置类
@ComponentScan({"com.practice.service"})//扫描包路径
@PropertySource("jdbc.properties")//获取资源路径
@Import({JdbcConfig.class,MybatisConfig.class})//spring与mybatis整合
public class SpringConfig {
}

2.3.2添加Jdbc配置类

• 创建jdbc属性文件并添加如下代码表示连接数据库信息

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybatis
jdbc.username=root
jdbc.password=123456

• 在com.practice.config下创建JdbcConfig配置类

package com.practice.config;import com.alibaba.druid.pool.DruidDataSource;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;import javax.sql.DataSource;/*** @Author YJ* @Date 2023/8/13 16:51* Description:Jdbc配置类*/
public class JdbcConfig {/*jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/mybatisjdbc.username=rootjdbc.password=123456*///通过注解，将jdbc属性文件中的属性获取到@Value("${jdbc.driver}")private String driver;@Value("${jdbc.url}")private String url;@Value("${jdbc.username}")private String username;@Value("${jdbc.password}")private String password;@Beanpublic DataSource dataSource(){DruidDataSource dataSource = new DruidDataSource();dataSource.setDriverClassName(driver);dataSource.setUrl(url);dataSource.setUsername(username);dataSource.setPassword(password);return dataSource;}
}

2.3.3添加Mybatis配置类

package com.practice.config;import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.context.annotation.Bean;import javax.sql.DataSource;/*** @Author YJ* @Date 2023/8/13 16:52* Description:Mybatis配置类*/
public class MybatisConfig {@Beanpublic SqlSessionFactoryBean sqlSessionFactoryBean(DataSource dataSource){SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();factoryBean.setDataSource(dataSource);factoryBean.setTypeAliasesPackage("com.practice.domain");return factoryBean;}@Beanpublic MapperScannerConfigurer mapperScannerConfigurer(){MapperScannerConfigurer msc = new MapperScannerConfigurer();msc.setBasePackage("com.practice.dao");return msc;}
}

2.3.4创建整合类（整合Spring和SpringMVC）

package com.practice.config;import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;/*** @Author YJ* @Date 2023/8/13 17:12* Description:整合Spring和SpringMVC*/
public class ServletConfig extends AbstractAnnotationConfigDispatcherServletInitializer {@Overrideprotected Class<?>[] getRootConfigClasses() {return new Class[]{SpringConfig.class};}@Overrideprotected Class<?>[] getServletConfigClasses() {return new Class[]{SpringMVCConfig.class};}@Overrideprotected String[] getServletMappings() {return new String[]{"/"};}
}

2.3.5创建SpringMVC配置类

package com.practice.config;import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;/*** @Author YJ* @Date 2023/8/13 17:13* Description:SpringMVC配置类*/
@Configuration
@ComponentScan("com.practice.controller")
@EnableWebMvc
public class SpringMVCConfig {
}
