嗨,我正在尝试测试一个连接到mysqllocalhost(examplep(的web服务Soap java,但我无法在数据库中插入任何行这是我的代码
Conexion.java
import java.sql.Connection
import java.sql.DriverManager
public class Conexion {
public static final Connection ConectarMySQL() throws SQLException
{
Connection conn;
try
{
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/controldecalidad", "root", "");
}
catch(SQLException ex)
{
throw new SQLException(ex.getMessage());
}
return conn;
}
}
这是网络服务
@WebMethod(operationName= "registra_rechazo")
public void registra_rechazo(@WebParam(name = "SKU")String SKU,@WebParam(name = "fecha")String fecha,
@WebParam(name = "num_captura")String num_captura,@WebParam(name = "pesoCaptura") int pesoCaptura)
{
try
{
Connection conn = Conexion.ConectarMySQL();
String sql = "INSERT INTO registra_rechazo VALUES(?,?,?,?)";
PreparedStatement pst = conn.prepareStatement(sql);
pst.setString(1, SKU);
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-mm-dd");
pst.setString(2, dateFormat.format(fecha));
pst.setString(3, num_captura);
pst.setInt(4, pesoCaptura);
pst.execute();
pst.close();
conn.close();
}
catch(SQLException Ex)
{
}
}
这是错误https://i.stack.imgur.com/aWO16.png
更新我检查了我的项目,发现了这个新错误https://i.stack.imgur.com/uHRQW.png
我缺了什么?请帮忙!!!!
我终于解决了
在类Conexion y中删除静态final,然后我为这个类创建一个构造函数
public class Conexion {
public Conexion(){
}
public Connection getConecction()
{
Connection con = null;
try{
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection("jdbc:mysql://localhost:3306/controldecalidad", "root", "");
}catch(SQLException ex){
}
catch(Exception ex){
}
return con;
}
}
然后我创建了一个拥有所有操作的类
public class Operaciones
{
Conexion conexion;
public Operaciones()
{
conexion = new Conexion();
}
public boolean registra_rechazo(String SKU,String fecha,String num_captura,int pesoCaptura)
{
Boolean bandera=false;
try
{
Connection conn = conexion.getConecction();
java.util.Date utilStartDate = new java.util.Date(fecha);
java.sql.Date sqlStartDate = new java.sql.Date(utilStartDate.getTime());
String sql = "INSERT INTO registra_rechazo VALUES(?,?,?,?)";
PreparedStatement pst = conn.prepareStatement(sql);
pst.setString(1, SKU);
pst.setDate(2, sqlStartDate);
pst.setString(3, num_captura);
pst.setInt(4, pesoCaptura);
if(pst.executeUpdate()!=-1){
bandera = true;
return bandera;
}
else{
bandera = false;
return bandera;
}
}
catch(SQLException Ex)
{
}
return bandera;
}
}
然后我调用web服务中的方法,但首先必须通过在web服务中添加操作(如图像(来创建web方法

我不知道为什么,但只有当你用向导创建方法时,这个方法才有效
@WebMethod(operationName = "operation")
public boolean operation(@WebParam(name = "SKU") String SKU, @WebParam(name = "fecha") String fecha, @WebParam(name = "num_captura") String num_captura, @WebParam(name = "peso_captura") int peso_captura) {
//TODO write your implementation code here:
Operaciones op = new Operaciones();
return op.registra_rechazo(SKU,fecha,num_captura,peso_captura);
}
然后web方法必须返回一些东西,带有void的将不起作用
