1、Vue的快速入门
2、Vue的语法
插值表达式
事件的绑定
数据的显示
逻辑判断和循环输出
3、Vue的生命周期
8个生命周期的执行点
4个基本的
4个特殊的
4、axios的ajax异步请求
它和jquery的ajax比较相似
5、综合案例
实现用户的查询列表和更新操作
前端:Vue
后端:ssm
18案例-创建数据库和工程
vuejsdemo.sql
DROP TABLE IF EXISTS `user`; CREATE TABLE `user` ( `id` int(11) NOT NULL AUTO_INCREMENT, `age` int(11) DEFAULT NULL, `username` varchar(20) DEFAULT NULL, `PASSWORD` varchar(50) DEFAULT NULL, `email` varchar(50) DEFAULT NULL, `sex` varchar(20) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8; INSERT INTO `user` VALUES (‘1‘, ‘33‘, ‘张老师‘, ‘123‘, ‘[email protected]‘, ‘男 ‘); INSERT INTO `user` VALUES (‘2‘, ‘31‘, ‘刘老师‘, ‘123‘, ‘[email protected]‘, ‘女‘); INSERT INTO `user` VALUES (‘3‘, ‘17‘, ‘赵工‘, ‘213‘, ‘[email protected]‘, ‘女‘); INSERT INTO `user` VALUES (‘4‘, ‘40‘, ‘高管‘, ‘213‘, ‘[email protected]‘, ‘female‘); INSERT INTO `user` VALUES (‘5‘, ‘28‘, ‘李总‘, ‘312‘, ‘[email protected]‘, ‘male‘); INSERT INTO `user` VALUES (‘6‘, ‘34‘, ‘王董‘, ‘312‘, ‘[email protected]‘, ‘male‘); INSERT INTO `user` VALUES (‘7‘, ‘55‘, ‘孙老板‘, ‘4321‘, ‘[email protected]‘, ‘男‘); INSERT INTO `user` VALUES (‘8‘, ‘19‘, ‘陈秘书‘, ‘4321‘, ‘[email protected]‘, ‘女‘);

19案例-编写实体类持久层和业务层代码
因为是mysql单表操作CRUD
所以可以选用: 通用mapper + DAO层接口继承 + 实体类注解映射 的方案
<dependency><!--通用mapper对spring的集成--> <groupId>tk.mybatis</groupId> <artifactId>mapper-spring</artifactId> <version>1.1.5</version> </dependency> <dependency><!--Mybatis 通用 Mapper Jar 集成--> <groupId>tk.mybatis</groupId> <artifactId>mapper</artifactId> <version>4.1.5</version> </dependency>
DAO层的接口类
cn.bjut.mapper.IUserMapper
package cn.bjut.mapper; import cn.bjut.domain.User; import org.springframework.stereotype.Repository; import tk.mybatis.mapper.common.Mapper; /** * 用户表的持久层接口 */ @Repository //IOC注入容器对象 //引入通用mapper启动器依赖后,DAO层接口继承Mapper<E> public interface IUserMapper extends Mapper<User> { }
数据库实体类
cn.bjut.domain.User
package cn.bjut.domain; import tk.mybatis.mapper.annotation.KeySql; import javax.persistence.Id; import javax.persistence.Table; import java.io.Serializable; /** * 用户表的实体类 */ @Table(name = "user") public class User implements Serializable { @Id @KeySql(useGeneratedKeys = true) private Integer id; private String username; private String password; private Integer age; private String sex; private String email; //=========省略get/set方法和toString()===========//
配置文件在resources目录:
SSM框架整合数据源的
db.properties
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/leyou jdbc.username=root jdbc.password=root
控制台日志输出的
