Question

当我使用帮助Gradle运行项目时，我会遇到异常：

这个项目在我同事的笔记本电脑上运行得很好。此外，这段代码对我有用：

public static void main(String[] args) throws SQLException, ClassNotFoundException 
{
    Class.forName("com.mysql.jdbc.Driver");

    Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/database?characterEncoding=UTF-8", "login", "password");

    Statement stmt = conn.createStatement();

    String strSelect = "SELECT * FROM `database`.tbl";
    ResultSet rset = stmt.executeQuery(strSelect);

    while (rset.next()) {   
        String f = rset.getString("field");
        System.out.println(f);
    }
}

此代码可能存在问题：

@Bean
public DataSource dataSource() {
    SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
    dataSource.setDriverClass(com.mysql.jdbc.Driver.class);
    dataSource.setUsername("login");
    dataSource.setUrl("jdbc:mysql://localhost:3306/database?characterEncoding=UTF-8");
    dataSource.setPassword("password");

    return dataSource;
}

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(dataSource());
    //
    return em;
}

P.S。我的操作系统是Windows 7.我在管理权限下启动我的IDE。

P.S.S。所有表都存在。

我不知道为什么，但Groovy配置中的这一行（build.gradle）解决了我的问题。

Line 1 of file: import static jdk.nashorn.internal.objects.NativeRegExp.compile

org.hibernate.HibernateException：缺少表：全部
