一、spring环境搭建

• maven引入依赖
• 配置spring.xml
• 编写启动类

        
            org.apache.commons
            commons-dbcp2
        
        
            org.springframework.boot
            spring-boot-starter
        
       
        
            org.springframework.boot
            spring-boot-starter-test
            test
        
      
        
            junit
            junit
        

        
            org.mybatis.spring.boot
            mybatis-spring-boot-starter
            1.3.2
        

        
            mysql
            mysql-connector-java
            runtime
        
        
            com.h2database
            h2
            1.4.196
        
        
            com.h2database
            h2
        
        
            com.h2database
            h2
        
    

driver: org.h2.Driver
username: test
password: test
url: jdbc:h2:mem:zczhang;DB_CLOSE_DELAY=-1;MODE=MySQL
schema: classpath:db/schema.sql

public class App {

    public static void main(String[] args) {
        ClassPathXmlApplicationContext ctx = new 
                                 ClassPathXmlApplicationContext("spring.xml");
    }

}
