java连接数据库工具类

　　以前写项目一直用框架，封装实体很方便，这次直接用servlet和jsp写，自己封装数据，好多重复的代码，又刚好复习了反射机制，所以自己写了个工具类。

1.team 表中字段

2.实体Team类

package com.beb.entity;public class Team {  private Integer id;  private String teamId;  private String teamName;  private String teamDesc;      public Integer getId() {    return id;  }  public void setId(Integer id) {    this.id = id;  }  public String getTeamId() {    return teamId;  }  public void setTeamId(String teamId) {    this.teamId = teamId;  }  public String getTeamName() {    return teamName;  }  public void setTeamName(String teamName) {    this.teamName = teamName;  }  public String getTeamDesc() {    return teamDesc;  }  public void setTeamDesc(String teamDesc) {    this.teamDesc = teamDesc;  }  @Override  public String toString() {    return "Team [id="+id+", teamId=" + teamId + ", teamName=" + teamName        + ", teamDesc=" + teamDesc + "]";  }  public Team(String teamId, String teamName, String teamDesc) {    this.teamId = teamId;    this.teamName = teamName;    this.teamDesc = teamDesc;  }  public Team() {    }    }
