数据库

建立数据库，用来测试

CREATE DATABASE ssm_conformity;
USE ssm_conformity;
CREATE TABLE tab_test(
    id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    testName VARCHAR(20)
);
INSERT INTO tab_test(testName) VALUES(‘admin‘);

配置

数据库配置文件 "datasource.properties"

jdbc.driver=com.mysql.jdbc.Driver
# 修改你的数据库连接地址
jdbc.url=jdbc:mysql:///ssm_conformity
# 修改数据连接用户密码
jdbc.username=root
jdbc.password=root

sping相关配置 "applicationContext.xml" 把需要改的包名改下即可
