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.Driver jdbc.url=jdbc:mysql://localhost:3306/mybatis jdbc.username=root jdbc.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; @Bean public 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 { @Bean public SqlSessionFactoryBean sqlSessionFactoryBean(DataSource dataSource){ SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean(); factoryBean.setDataSource(dataSource); factoryBean.setTypeAliasesPackage("com.practice.domain"); return factoryBean; } @Bean public 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 { @Override protected Class<?>[] getRootConfigClasses() { return new Class[]{SpringConfig.class}; } @Override protected Class<?>[] getServletConfigClasses() { return new Class[]{SpringMVCConfig.class}; } @Override protected 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 { }
