1. 首先定义一个数据的上下文的class文件
2.定义一个springboot线程池的全局方法：
3.关于一些常量的定义，直接在config里面配置即可
1. 首先定义一个数据的上下文的class文件
代码语言：javascript复制import java.util.Map;
public class DataCaptureContext {
private static final ThreadLocal<Map<String, Object>> threadLocalDataCapture = new ThreadLocal();
public static final String CURRENT_TIME = "current_time";
public DataCaptureContext() {
}
public static Map getMapData() {
Map mapData = null;
Object obj = threadLocalDataCapture.get();
if (obj != null) {
mapData = (Map)obj;
}
return mapData;
}
public static void setMapData(Map<String, Object> mapData) {
if (mapData != null) {
threadLocalDataCapture.set(mapData);
}
}
public static void removeMapData() {
threadLocalDataCapture.remove();
