spring之IOC基于注解注入集合属性

public class AccountDaoImpl implements AccountDao { private String[] myStrs; private List<String> myList; private Set<String> mySet; private Map<String, String> myMap; private Properties myProps; public void setMyStrs(String[] myStrs) { this.myStrs = myStrs; } public void setMyList(List<String> myList) { this.myList = myList; } public void setMySet(Set<String> mySet) { this.mySet = mySet; } public void setMyMap(Map<String, String> myMap) { this.myMap = myMap; } public void setMyProps(Properties myProps) { this.myProps = myProps; } public void showAccount() { System.out.println(Arrays.toString(myStrs)); System.out.println(myList); System.out.println(mySet); System.out.println(myMap); } }
