在配置类重写jdbcProperties方法

// 数据源，必配，用的是阿里巴巴的 druid数据源，其他属性可自行查阅
@Override
public List jdbcProperties() {
    List list = new ArrayList();
    Properties properties = new Properties();
    properties.put("name","dataSource");
    properties.put("url","jdbc:mysql://10.211.55.15:3306/mars?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8");
    properties.put("username","root");
    properties.put("password","Root123456!");
    properties.put("driverClassName","com.mysql.jdbc.Driver");
    list.add(properties);
    // 如果要多个数据源，add多个到list即可
    return list;
}
