黑马eesy_15 Vue：02.常用语法

黑马eesy_15 Vue：03.生命周期

 

 

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

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

log4j.properties

# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE, LOGFILE          debug   info   warn error fatal
log4j.rootCategory=debug, CONSOLE

# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE

# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

# LOGFILE is set to be a File appender using a PatternLayout.
# log4j.appender.LOGFILE=org.apache.log4j.FileAppender
# log4j.appender.LOGFILE.File=d:\axis.log
# log4j.appender.LOGFILE.Append=true
# log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
# log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
