public class Table {
String tableName;
String mainPropertyName;
static int count=1;
static DBExcute dbExcute=(DBExcute)new ClassPathXmlApplicationContext("applicationContext.xml").getBean("dbExcute");
Table(String tableName,String mainPropertyName){
this.tableName=tableName;
this.mainPropertyName=mainPropertyName;
System.out.println("construct table"+(count++)+" use:"+dbExcute);
}

public static void main(String []dsf){
new Table("user","1");
}
}
如上只new Table(..)一次:
结果却是:
construct table1 use:null
construct table2 use:null
construct table3 use:null
construct table4 use:null
construct table5 use:null
construct table6 use:com.yijia_ctgu.DB.DBExcute@535b58
奇怪中。。。。。。。
明白了,spring容器初始化的时候,初始化dbDAO bean会生成五个table,可能是先初始化,后才赋值给dbExcute,所以刚开始的五个都是null.
