项目中日志系统封装
常规日志实体类

异常日志实体类

封装数据库连接
| package com.cloud.day2; import org.springframework.jdbc.core.JdbcTemplate; import org.springframework.orm.hibernate3.HibernateTemplate; public class BaseJdbcSupport { private HibernateTemplate hibernateTemplate; private JdbcTemplate jdbcTemplate; public HibernateTemplate getHibernateTemplate() { return hibernateTemplate; } public void setHibernateTemplate(HibernateTemplate hibernateTemplate) { this.hibernateTemplate = hibernateTemplate; } public JdbcTemplate getJdbcTemplate() { return jdbcTemplate; } public void setJdbcTemplate(JdbcTemplate jdbcTemplate) { this.jdbcTemplate = jdbcTemplate; } } |
日志接口
| package com.cloud.day3; public interface LogServiceInte { /** * 处理正常情况下的日志记录 * @param modelName 模块名称：商品模块，用户模块，等等 * @param codeEvent 事件名称：查询，删除，添加，等等 * @param date 处理时间 * @param userID 操作的用户 * @param systemType 操作系统：APP，接口，web端 */ public void saveLog(String modelName,String codeEvent,String date,String userID,String systemType); /** * 发生异常的情况下的日志记录 * @param className 类名 * @param methodName 方法名 * @param exceptionName 异常名 * @param desException 异常描述 * @param remark 备注 */ public void saveException(String className,String methodName,String exceptionName,String desException,String remark); } |
日志接口实现类
