因为没有id为head的fragment的存在于_fragments下 ,所以没有解析找到他,你首先要创建一个(_fragments) html在其中创建一个id为head的fragment,

才能在index.html中用th:replace来引用他:

可以参考:

有哪位大神帮一下忙吗

index.html ,第5行 ，表达式写错了。

你可以把index.html 代码贴出来。

<!DOCTYPE html>
<!--<html lang="en" xmlns:th="http://www.thymeleaf.org">-->
<!--<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">-->
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
<head th:replace="_fragments :: head(~{::title})">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width,initial-scale=1.0">
    <title>首页</title>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/semantic-ui@2.4.2/dist/semantic.min.css">
    <link rel="stylesheet" href="../static/css/me.css" th:href="@{css/me.css}">
</head>
<body>


第五行是找不到replace="_fragments吗



解析 _fragments 错误，看路径对着没，和这个模板页面里有问题没。

模板李没问题啊，就是这个_fragments在哪里

尝试把那个东西去掉了，还是报第一个错误

org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "class path resource [templates/index.html]")

把index.html放在templates/index.html试试,模板解析器尝试从templates/index.html中解析index,未找到

可以截个resources文件的结构图吗


已经在那个目录下面了，而且使用这个标签的时候，会提示黄色，也会报错，不懂是为什么




试试这个:

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<!--<head th:replace="_fragments :: head(~{::title})">-->
<head >
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width,initial-scale=1.0">
    <title>首页</title>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/semantic-ui@2.4.2/dist/semantic.min.css">
    <link rel="stylesheet" href="../static/css/me.css" th:href="@{css/me.css}">
</head>
<body>
</body>
</html>

使用thymeleaf的,注释掉XML的


index.html的后缀改为htm试试

index.htm



<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<!--<head th:replace="_fragments :: head(~{::title})">-->
<head >
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width,initial-scale=1.0">
    <title>首页</title>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/semantic-ui@2.4.2/dist/semantic.min.css">
    <link rel="stylesheet" href="../static/css/me.css" th:href="@{css/me.css}">
</head>
<body>
</body>
</html>

还是报这个问题呀

[THYMELEAF][http-nio-8080-exec-1] Exception processing template "index": An error happened during template parsing (template: "class path resource [templates/index.html]")

完整日志

输出的错误日志好像有些有提示第几行出错吧

谢谢各位大佬的辛苦，经过一天思考和查阅博客，上述是 ①_fragments的问题 ②xmlns:th="http://www.thymeleaf.org" xmlns="http://www.w3.org/1999/xhtml 要同时引入 ③不存在的属性删除，或者把类.属性换成类.get属性 ④xml文件引入<dependency>

<groupId>net.sourceforge.nekohtml</groupId>

<artifactId>nekohtml</artifactId>

<version>1.9.22</version>

</dependency>

⑤引入本地图片 要在后面加上href="../static/css/me.css" th:href="@{css/me.css} ，这个依赖于http://www.thymeleaf.org，而引入属性和js等样式依赖于www.w3.org/1999/xhtml，所以我都同时引入试了一下，不懂是什么原理
