2. 创建相关配置文件
2.1 数据库
2.1.1 数据库链接信息
在resource文件夹里新建jdbc.properties文件

| jdbc.driverClassName=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/health?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
jdbc.username=root
jdbc.password=123456

@Bean
public DataSource dataSource() {
DruidDataSource dataSource = new DruidDataSource();
dataSource.setDriverClassName(driverClassName);
dataSource.setUrl(url);
dataSource.setUsername(username);
dataSource.setPassword(password);
return dataSource;
}
}

@Bean
public SqlSessionFactoryBean sqlSessionFactory(DataSource dataSource) {
SqlSessionFactoryBean factory = new SqlSessionFactoryBean();
factory.setDataSource(dataSource);
factory.setTypeAliasesPackage("club.summerain0.health.entity");
return factory;
}
@Bean
public MapperScannerConfigurer mapperScannerConfigurer() {
MapperScannerConfigurer configurer = new MapperScannerConfigurer();
configurer.setBasePackage("club.summerain0.health.mapper");
return configurer;
}
}

2.3 添加SpringMVC的配置文件
创建SpringMvcConfig.java

@Configuration
@ComponentScan("club.summerain0.health.controller")
@EnableWebMvc
public class SpringMvcConfig {
}

2.4 添加Spring配置文件
创建SpringConfig.java

@Configuration
@ComponentScan("club.summerain0.health.service")
@PropertySource("classpath:jdbc.properties")
@Import({JdbcConfig.class, MyBatisConfig.class})
public class SpringConfig {
}
|
3. 配置容器启动配置
创建ServletConfig.java，继承WebApplicationInitializer的子类在启动的时候被Tomcat自动调用

| 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[]{"/"};
}
}

自此，一个最基本的SSM项目配置完毕。
