无法执行目标org.springframework.boot：spring-boot-maven-plugin：1.3.3.RELEASE：run

时间：2016-04-12 02:26:46

标签： java eclipse spring hibernate maven

我是java spring和hibernate的新手。我使用maven来管理我的项目，我无法理解我有什么问题。这很奇怪。我在这里呆了一个星期。 这是完整错误

 String update = "INSERT INTO help("name","area","date","message") VALUES(?, ?, ?, ?)";
    statement.setString(1, name);
    statement.setString(2, area);
    statement.setString(3, date);
    statement.setString(4, message);

这是我的项目树： project tree Config.java文件：

很抱歉，如果这是一个愚蠢的问题，我是一个新手，我无法解决它一个星期。感谢您的支持。 ：）

答案 0 :(得分：0)

该错误表明无法确定数据库驱动程序。

  

无法确定数据库类型为NONE的嵌入式数据库驱动程序类。

尝试显式设置连接URL：

spring.datasource.url=jdbc:mysql://localhost:3306/testdkt

我在https://www.journaldev.com/13830/spring-boot-cannot-determine-embedded-database-driver-class-for-database-type-none

找到了

希望这会有所帮助

答案 1 :(得分：-1)

即使我也遇到过同样的问题，但是一旦我将以下类包含在src / main / java包中，我就可以继续。

<?php
require 'varDx.php';
$dx = new \varDx\cDX; //create an object
$dx->def('file.dat'); //define data file

$val1 = "this is a string";
$dx->write('data1', $val1); //writes key to file
echo $dx->read('data1'); //returns key value from file
