多线程实现 重写run（），怎么注入使用mapper文件操作数据库

public class EchoThread implements Runnable{
private Socket client;

InputStream inputStream;private TestUtils testUtils;

// @Autowired
// private EquipmentMapper equipmentMapper = SpringContextUtil.getBean(EquipmentMapper.class);
@Autowired
private EquipmentMapper equipmentMapper;

public EchoThread(Socket client){    this.client=client;}@[email protected] void run() {    //this.equipmentMapper= BeanContext.getApplicationContext().getBean(EquipmentMapper.class);    try {        while (true){            inputStream=client.getInputStream();            byte[] bytes = new byte[1024];            inputStream.read(bytes);            String string = new String(bytes);            System.out.println("我是传过来的数"+string);            String[] str = string.split("AAAA");            StringBuffer sb = new StringBuffer();            List<Equipment> equipmentList = new ArrayList<>();            List storage = new ArrayList();            Equipment equipment = new Equipment();            System.out.println("我是str"+str);            //String sql = "INSERT INTO TABLE_NAME VALUES (?,?,?)";//插入sql            for (int i=0; i<str.length;i++){                String dd =str[i].toString();                System.out.println("我是dd分隔后的数"+dd);                String ee=dd.substring(0,6);                System.out.println("我是ee分隔后的数"+ee);                if(ee.equals("040302") ){                    String ee1=dd.substring(6,10);                    // System.out.println("我是最新测试"+ee1);                    long put_Vlue = Long.parseLong(ee1, 16);//Long.parseLong(字符串,该字符串为几进制)                    storage.add("溶解氧："+put_Vlue*0.001);                    // System.out.println(put_Vlue);//输出结果                    //System.out.println("我我我我我我我我"+storage);                    System.out.println("溶解氧："+put_Vlue);                    equipment.setDissolvedName("溶解氧");                    equipment.setDissolvedValue(put_Vlue*0.001);                    equipmentList.add(equipment);                    System.out.println("我是是是是"+equipmentList);                }else if(ee.equals("050404")){                    String ee1=dd.substring(6,10);                    String ee2=dd.substring(10,14);                    //System.out.println("我是最新测试"+ee2);                    long put_Vlue = Long.parseLong(ee1, 16);//Long.parseLong(字符串,该字符串为几进制)                    long put_Vlue2 = Long.parseLong(ee2, 16);                    storage.add("土壤温湿度："+put_Vlue*0.1+","+put_Vlue2*0.1);                    System.out.println("土壤温湿度");                    equipment.setSoilName("土壤温湿度");                    equipment.setSoilValue(put_Vlue*0.1);                   // equipment.setSoilValue(String.valueOf(put_Vlue2*0.1));                    equipmentList.add(equipment);                }else if(ee.equals("070302")){                    String ee1=dd.substring(6,10);                    long put_Vlue = Long.parseLong(ee1, 16);                    storage.add("浊度："+put_Vlue*0.01);                    System.out.println("浊度");                    equipment.setTurbidityName("浊度");                    equipment.setTurbidityValue(put_Vlue*0.01);                    equipmentList.add(equipment);                }else if(ee.equals("030302")){                    String ee1=dd.substring(6,10);                    long put_Vlue = Long.parseLong(ee1, 16);                    storage.add("水质PH："+put_Vlue*0.01);                    System.out.println("水质PH");                    equipment.setWaterName("水质PH");                    equipment.setWaterValue(put_Vlue*0.01);                    equipmentList.add(equipment);                }else if(ee.equals("060302")){                    String ee1=dd.substring(6,10);                    long put_Vlue = Long.parseLong(ee1, 16);                    storage.add("土壤PH："+put_Vlue*0.01);                    System.out.println("土壤PH");                    equipment.setSoilPHName("土壤PH");                    equipment.setSoilPHValue(put_Vlue*0.01);                    equipmentList.add(equipment);                }else if(ee.equals("010302")){                    String ee1=dd.substring(6,10);                    long put_Vlue = Long.parseLong(ee1, 16);                    storage.add("水温："+put_Vlue*1);                    System.out.println("水温");                    equipment.setTemperatureName("水温");                    equipment.setTemperatureValue(put_Vlue*1);                    equipmentList.add(equipment);                }else if(ee.equals("080304")){                    String ee1=dd.substring(6,14);                    System.out.println("明渠流量计");                    equipment.setChannelName("明渠流量计");                    equipment.setChannelValue(30.2);                    equipmentList.add(equipment);                }else if(ee.equals("020302")){                    String ee1=dd.substring(6,10);                    long put_Vlue = Long.parseLong(ee1, 16);

}else{
System.out.println("没有数据");
}
}
System.out.println("我是最后传递的list"+equipmentList);
equipmentMapper.equipserter(equipmentList);

 } } catch (IOException e) { e.printStackTrace(); }}

}

我想调用mapper把数据存入数据库中，但是调用一直是null，这个要怎么解决有知道的牛人
