使用Spring替换properties文件定义属性的方法

 
工作中，领导认为properties文件太恶心（其实就不想让用），还好properties文件就是一个字符串的问题，下面我将Spring怎么实例化String、File、Map、List对象的常见方法列下面。供大家参考。废话不多说，还是上代码吧。

</beans>

public class MyDemo {

 private List<String> nameList = null;

 private Map<String, List<String>> nameMap = null;

 public List<String> getNameList() {
  return nameList;
 }

 public void setNameList(List<String> nameList) {
  this.nameList = nameList;
 }

 public Map<String, List<String>> getNameMap() {
  return nameMap;
 }

 public void setNameMap(Map<String, List<String>> nameMap) {
  this.nameMap = nameMap;
