SpringBoot+Thyemleaf报错：Error resolving template Template might not exist or might not be accessible

缘起

日前在搭建项目的时候使用的是SpringBoot+Thymeleaf框架，在访问页面的时候报错

org.thymeleaf.exceptions.TemplateInputException: Error resolving template xx，Template might not exist or might not be accessible

基本配置如下：

yml：

thymeleaf:
    prefix: classpath:/templates/view/
    suffix: .html
    mode: HTML5
    encoding: UTF-8
    servlet:
      content-type: text/html
    cache: false

pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

controller

@RequestMapping("index")
public String index(Model model) {
    System.out.println("index");
    return "helloworld";
}

html

最终解决方案

是因为在pom中配置了文件过滤

<resource>
    <directory>src/main/resources</directory>
    <includes>
        <include>**/*.yaml</include>
        <include>**/*.yml</include>
        <include>**/*.properties</include>
        <include>**/*.vm</include>
    </includes>
    <filtering>true</filtering>
</resource>

可以看到这边是没有包含html的，改成如下配置就可以了

<resource>
    <directory>src/main/resources</directory>
<!--<includes>-->
<!--   <include>**/*.yaml</include>-->
<!--   <include>**/*.yml</include>-->
<!--   <include>**/*.properties</include>-->
<!--   <include>**/*.vm</include>-->
<!--</includes>-->
    <filtering>true</filtering>
</resource>

或者加上html

<resource>
    <directory>src/main/resources</directory>
    <includes>
        <include>**/*.yaml</include>
        <include>**/*.yml</include>
        <include>**/*.properties</include>
        <include>**/*.vm</include>
        <include>**/*.html</include>
    </includes>
    <filtering>true</filtering>
</resource>
