基于ssm的考勤设备和考勤记录管理系统------（三）
1.接着上一篇，写设备管理的部分
主要界面如下图
2.这里面有增删改查的基本功能，还有分页的查询，关键词查询，还有定时刷新的功能
实体类如下
package com.timmy.entity;
public class Device {
private Integer id;
private String serialNum;
private String deviceName;
private String area;
private Integer status;
private Integer province;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getSerialNum() {
return serialNum;
}
public void setSerialNum(String serialNum) {
this.serialNum = serialNum == null ? null : serialNum.trim();
}
public String getDeviceName() {
return deviceName;
}
public void setDeviceName(String deviceName) {
this.deviceName = deviceName == null ? null : deviceName.trim();
}
public String getArea() {
return area;
}
public void setArea(String area) {
this.area = area == null ? null : area.trim();
}
public Integer getStatus() {
return status;
}
public void setStatus(Integer status) {
this.status = status;
}
public Integer getProvince() {
return province;
}
public void setProvince(Integer province) {
this.province = province;
}
@Override
public String toString() {
return "Device [id=" + id + ", serialNum=" + serialNum
+ ", deviceName=" + deviceName + ", area=" + area + ", status="
+ status + "]";
}
}mapper
id, serial_num, device_name, area, status,province
delete from device
where id = #{id,jdbcType=INTEGER}
delete from device where serial_num = #{serialNum,jdbcType=VARCHAR}
insert into device (id, serial_num, device_name,
area, status,province)
values (#{id,jdbcType=INTEGER}, #{serialNum,jdbcType=VARCHAR}, #{deviceName,jdbcType=VARCHAR},
#{area,jdbcType=VARCHAR}, #{status,jdbcType=INTEGER},#{province,jdbcType=INTEGER})
insert into device
id,
serial_num,
device_name,
area,
status,
province,
#{id,jdbcType=INTEGER},
#{serialNum,jdbcType=VARCHAR},
#{deviceName,jdbcType=VARCHAR},
#{area,jdbcType=VARCHAR},
#{status,jdbcType=INTEGER},
#{province,jdbcType=INTEGER},
update device
serial_num = #{serialNum,jdbcType=VARCHAR},
device_name = #{deviceName,jdbcType=VARCHAR},
area = #{area,jdbcType=VARCHAR},
status = #{status,jdbcType=INTEGER},
province = #{province,jdbcType=INTEGER},
where id = #{id,jdbcType=INTEGER}
update device
set serial_num = #{serialNum,jdbcType=VARCHAR},
device_name = #{deviceName,jdbcType=VARCHAR},
area = #{area,jdbcType=VARCHAR},
status = #{status,jdbcType=INTEGER},
province = #{province,jdbcType=INTEGER}
where id = #{id,jdbcType=INTEGER}
update device set status = #{status,jdbcType=INTEGER}
where id = #{id,jdbcType=INTEGER}
需要注意的只有下面的这一部分，这回事关键词查询的语句
实体类和mapper映射都可以使用mybaties-generator逆向生成工具进行生成
mybatis-generator-core-1.3.2.zip解压放在本地文件夹中
下载地址：https://download.csdn.net/download/moshubai/11941711
然后修改
这个文件里面数据库的配置，如下
修改成自己的，然后在命令行进入
这个文件所在目录。输入java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig.xml -overwrite，回车，就会在 src文件中生成mapper和实体类了
3.接下来是controller部分，这部分是接收前端请求，并且调用后端的接口的。
