我是想在jsp里面调用Bean来增加数据到数据库的，实际代码如下，执行后说插入不成功，各位看问题出在哪里：
Bean.java
--------------------
package bean;
import java.sql.*;
public class Bean extends Dcl{
//以下是用户表操作部分
public boolean adduser(){
boolean bu_adduser=false;
try{
String usersql= "insert into usename(name,password,dept,pop) values( "+name+ ", "+password+ ", "+dept+ ", "+pop+ ") ";
if(super.insert(usersql))bu_adduser=true;
}catch(Exception e){
System.out.println( "增加用户失败 ");
}finally{
return bu_adduser;
}
}
public String getName(){
return name;
}
public void setName(String name){
this.name=name;
}
public String getPassword(){
return password;
}
public void setPassword(String password){
this.password=password;
}
public String getDept(){
return dept;
}
public void setDept(String dept){
this.dept=dept;
}
public String getPop(){
return pop;
}
public void setPop(String pop){
this.pop=pop;
}
}
Dcl.java
------------------------------------------
//package bean;
import java.sql.*;
public class Dcl{
String url= "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=myedit ";//数据库地址
String sa= "sa ";//数据库用户
String pw= "hello ";//数据库密码
String driver= "com.microsoft.jdbc.sqlserver.SQLServerDriver ";//数据库驱动
//String newsid;//文章ID
String username= " ";//作者ID
String title= " ";//文章标题
String content= " ";//文章内容
String datenews= " ";//文章日期
//String usernameid;//用户表ID号
String name= " ";//用户名
String password= " ";//用户密码
String dept= " ";//用户类型
String pop= " ";//权限
String sql= " ";
ResultSet rs;
public Dcl(){
try{
Class.forName(driver).newInstance();
}catch(Exception e){
System.out.println( "驱动加载失败 ");
}
}
public boolean insert(String sql){
boolean boup=false;
rs=null;
try{
Connection conn=DriverManager.getConnection(url,sa,pw);
Statement stmt=conn.createStatement();
int insertcount=stmt.executeUpdate(sql);
if(insertcount> 0)boup=true;
}catch(SQLException e){
System.out.println( "增加失败 ");
}finally{
return boup;
}
}
}
adduser.jsp
