Start.java
就是输出点东西
1 package edu.uc.ui.cli; 2 3 import edu.uc.bean.Member; 4 import edu.uc.service.MemberService; 5 import edu.uc.service.impl.MemberServiceImpl; 6 7 public class Start { 8 public static void main(String []args) { 9 MemberService memberService = new MemberServiceImpl(); 10 11 String name= "t1"; 12 Member bean = memberService.loadByName(name); 13 14 System.out.println(bean.getUserId()); 15 System.out.println(bean.getUserName()); 16 System.out.println(bean.getUserPass()); 17 System.out.println(bean.getNickName()); 18 System.out.println(bean.getStatus()); 19 } 20 }
StartList.java
数据库的数据都输出来
1 package edu.uc.ui.cli; 2 3 import java.util.*; 4 5 import edu.uc.bean.Member; 6 import edu.uc.service.MemberService; 7 import edu.uc.service.impl.MemberServiceImpl; 8 9 public class StartList { 10 public static void main(String []args) { 11 MemberService memberService = new MemberServiceImpl(); 12 13 String name= "t1"; 14 List<Member> list= memberService.list(); 15 16 for(Member bean:list) { 17 System.out.println(bean.getUserId()+" "+bean.getUserName()+" "+bean.getUserPass()+" "+bean.getNickName()+" "+bean.getNickName()+" "); 18 //System.out.println(bean.getUserName()+" "); 19 //System.out.println(bean.getUserPass()+" "); 20 //System.out.println(bean.getNickName()+" "); 21 //System.out.println(bean.getNickName()+" "); 22 } 23 } 24 }
StartListByName.java
通过名字输出数据
1 package edu.uc.ui.cli; 2 3 import java.util.List; 4 5 import edu.uc.bean.Member; 6 import edu.uc.service.MemberService; 7 import edu.uc.service.impl.MemberServiceImpl; 8 9 public class StartListByName { 10 11 public static void main(String[] args) { 12 13 MemberService memberService = new MemberServiceImpl(); 14 15 String name = "t"; 16 List<Member> list = memberService.listByName(name); 17 18 for(Member bean : list) { 19 System.out.print(bean.getUserId()+" "); 20 System.out.print(bean.getUserName()+" "); 21 System.out.print(bean.getUserPass()+" "); 22 System.out.print(bean.getNickName()+" "); 23 System.out.println(bean.getStatus()); 24 } 25 26 27 28 } 29 30 }

界面其实现在用不到（理解）
但是代码至少一遍，敲多了就慢慢了解，要查，要写博客，收获
英语很重要，认真
打基础，不要眼高手低
（上面的都是对我自己说的）
