我目前正在尝试按照教程进行操作，但遇到问题时我会在内存持久性方面添加一些h2到应用程序。我在Spring Boot中发现了一些关于h2自动配置的评论，它说，唯一要做的就是将依赖项添加到pom中。我还需要手动进一步配置吗？ 我得到以下例外情况：

public ResponseEntity<?> getEntries() {

}
}
+++++++++++++++++++ UPDATE：
在pom.xml中注释掉显式的hibernate依赖项并运行maven clean install时，它仍然不起作用。 我用maven clean install得到了以下输出（不幸的是我不得不删除部分内容，因为它有超过90000个字符，这里只允许30k）：

答案 0 :(得分：0)
所以我终于弄清楚出了什么问题。 H2不在项目类路径中，因此我必须手动添加它。 您可以在此处下载：h2-db 然后通过右键单击项目将其添加到类路径中 - ＆gt; Properties-＆gt; Java构建路径 - ＆gt; Libraries-＆gt;添加外部jar。
但是我不知道，如果它是解决它的好方法，或者它应该以某种方式由Spring Boot或Maven依赖自动处理。
答案 1 :(得分：0)
在我看来你错过了H2依赖本身。您不需要使用spring-boot包含该版本，因为您将从spring-boot父pom继承它。只需在pom.xml中包含以下内容即可。
// ImgLiquid
$('.imgLiquidFill').imgLiquid({
fill: false,
verticalAlign: 'left'
});
// Slider advances on image click
var i = 0;
$('#slider img').click(function() {
$('#slider').carousel(++i);
});
