大家好我有一个Web服务来帮助我完成登录过程 但是当我运行代码时,我收到错误说“应用程序意外停止了........
这是我的网络服务:
package org.webserv.ws;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
public class hello {
public String authentication(String userName,String password) {
String retrievedUserName = "";
String retrievedPassword = "";
String status = "";
try {
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/android app.","","admin");
PreparedStatement statement = con.prepareStatement("SELECT * FROM user account info. WHERE username = '"+userName+"'AND password = '"+password+"'");
ResultSet result = statement.executeQuery();
while(result.next()){
retrievedUserName = result.getString("username");
retrievedPassword = result.getString("password");
}
if(retrievedUserName.equals(userName)&&retrievedPassword.equals(password)){
status = "Success!";
}
else { status = "Login fail!!!"; }
}
catch(Exception e) { e.printStackTrace(); }
return status;
}
}
这里是logcat

答案 0 :(得分:0)
ksoap2-android-assembly-2.6.2-jar-with-dependencies.jar
添加此jar文件/ libs文件夹,以便Eclipse ADT
自动将您的jar添加到应用程序的构建路径中。我希望这会对你有所帮助。
谢谢!
