Java调用存储过程（有返回值）

1：创建存储过程

此存储过程通过传入的参数（Name），返回一个参数（address）。

create or replace procedure demo_procedure(namedemo in varchar2,addressdemo out varchar2)
as
begin 
select address into addressdemo from system.demo where name=namedemo;
end;

2：Java代码：

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.sql.Types;  

public class TestProcedureTwo {
  public TestProcedureTwo() {
  }
  public static void main(String[] args ){
    String driver = "oracle.jdbc.driver.OracleDriver";
    String strUrl = "jdbc:oracle:thin:@localhost:1521:myoracle";
    Statement stmt = null;
    ResultSet rs = null;
    Connection conn = null;
    try {
      Class.forName(driver);
      conn =  DriverManager.getConnection(strUrl, "system", "admin");
      CallableStatement proc = null;
      proc = conn.prepareCall("{ call dem_procedure(?,?) }");
      proc.setString(1, "kalision");
      proc.registerOutParameter(2, Types.VARCHAR);
      proc.execute();
      String testPrint = proc.getString(2);
      System.out.println("存储过程返回的值是："+testPrint);
    }
    catch (SQLException ex2) {
      ex2.printStackTrace();
    }
    catch (Exception ex2) {
      ex2.printStackTrace();
    }
    finally{
      try {
        if(rs != null){
          rs.close();
          if(stmt!=null){
            stmt.close();
          }
          if(conn!=null){
            conn.close();
          }
        }
      }
      catch (SQLException ex1) {
      }
    }
  }
}  

注意：记得导入jdbc驱动的jar包。
