如果控制器中存在具有合适路径模板的方法，则 Spring Boot 不会提供静态资源。 我目前正在阅读“Spring Boot in Action”（2015 年）一书。第二章有示例工程。
项目结构如下：
.
├── pom.xml
└── src
├── main
│ ├── java
│ │ └── haven
│ │ ├── Book.java
│ │ ├── ReadingListApplication.java
│ │ ├── ReadingListController.java
│ │ └── ReadingListRepository.java
│ └── resources
│ ├── application.properties
│ ├── static
│ │ └── style.css
│ └── templates
│ └── readingList.html
└── test
└── java
└── haven
└── ReadingListApplicationTests.java
并使用以下依赖项：
org.springframework.boot:spring-boot-starter-data-jpa
org.springframework.boot:spring-boot-starter-thymeleaf
org.springframework.boot:spring-boot-starter-web
org.springframework.boot:spring-boot-starter-test
com.h2database:h2
我使用 2.4.5 spring boot 版本。
src/main/resources/templates/readingList.html 标头：
...
<head>
<title>Reading List</title>
<link rel="stylesheet" th:href="@{/style.css}"></link>
</head>
...
src/main/java/haven/ReadingListController.java :
package haven;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping(value = "/")
public class ReadingListController {
private ReadingListRepository readingListRepository;
@Autowired
public ReadingListController(ReadingListRepository readingListRepository) {
this.readingListRepository = readingListRepository;
}
@RequestMapping(value = "/{reader}", method = RequestMethod.GET)
public String readersBooks(@PathVariable(value = "reader") String reader,
Model model) {
List<Book> readingList = readingListRepository.findByReader(reader);
if(readingList != null) {
model.addAttribute("books", readingList);
}
System.out.println("reader name is " + reader);
return "readingList";
}
@RequestMapping(value = "/{reader}", method = RequestMethod.POST)
public String addToReaderList(@PathVariable(value = "reader") String reader,
Book book) {
book.setReader(reader);
readingListRepository.save(book);
return "redirect:{reader}";
}
}
如果我发出 GET 之类的 /andrew 请求，readersBooks 方法将执行三次。首先是 /andrew，然后是 /style.css，然后是 /favicon.ico。
如果我改变两个路径，例如这样
@RequestMapping(value = "/reader/{reader}", method = RequestMethod.GET)
@RequestMapping(value = "/reader/{reader}", method = RequestMethod.POST)
或完全删除这两种方法，然后按预期检索资源。 （在这里，我有点惊讶为什么更改 GET 的路径还不够。我开始收到 style.css 和 favicon.icon 的 405 错误。.w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'GET' not supported]）
This 回答对我有帮助。
我在 application.properties 中添加了以下几行：
spring.web.resources.chain.strategy.fixed.enabled=true
spring.web.resources.chain.strategy.fixed.paths=/**
spring.web.resources.chain.strategy.fixed.version=v1
为什么默认属性不够用？我看过几个教程，每个人都说只需将静态资源放在 paths 之一中，一切都会好起来的。本书中的代码适用于作者，但对我来说并不完全相同。也许有什么改变了？ 2015 年的书。这三个属性实际上有什么作用？
更新
我像在这个 guide 中那样向项目添加了 spring 安全性。
org.springframework.boot:spring-boot-starter-security
从现在开始，分为三组：
/ 和 /home - 每个人都可以随时使用/login - 用于身份验证，每个人都可以使用，而且总是可以使用/{reader} - 适用于授权用户添加了两个类：
src/main/java/haven/MvcConfig.java：
package haven;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
public class MvcConfig implements WebMvcConfigurer {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("home");
registry.addViewController("/home").setViewName("home");
registry.addViewController("/login").setViewName("login");
}
}
src/main/java/haven/WebSecurityConfig.java：
package haven;
import java.util.function.Function;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.factory.PasswordEncoderFactories;
import org.springframework.security.provisioning.InMemoryUserDetailsManager;
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/", "/home").permitAll()
.anyRequest().authenticated()
.and()
.formLogin().loginPage("/login").permitAll()
.and()
.logout().permitAll();
}
@Bean
@Override
protected UserDetailsService userDetailsService() {
Function<String, String> encoder = PasswordEncoderFactories.createDelegatingPasswordEncoder()::encode;
UserDetails user = User.withUsername("user")
.password("password").passwordEncoder(encoder)
.roles("USER")
.build();
return new InMemoryUserDetailsManager(user);
}
}

</form>
</body>
</html>
当我发出请求时，例如 /peter，服务器要求进行身份验证，重定向到 /login。但是它没有显示资源中的页面 login.html，而是将这个 /login 提供给控制器。控制器将页面 readingList.html 提供给读者名为“login”的用户。此外，此页面正在尝试提取资源 style.css 和 favicon.ico。但当然，用户仍然没有通过身份验证，Spring Security 又两次重定向到 /login。
换句话说，在添加spring security之前，控制台输出是：
reader name is peter
reader name is style.css
reader name is favicon.ico
但现在：
reader name is login
reader name is login
reader name is login
当然我只希望看到
reader name is peter
并且只有在授权后，如果添加了spring security。
看起来控制器优先于资源。即使经过网络安全！但如果我对 Craig Walls 的理解正确的话，应该正好相反。否则，无法获取资源，请求模式为 /{reader}。
也许这会有所帮助。
早些时候，当我使用 web.xml（在另一个项目中）时，我在 servlet 映射方面遇到了类似的问题，url 模式为 /*:
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
如果没有这种模式，资源会被正常拉取，不需要任何额外的信息。但是如果你添加它，那么像 /style.css 或 /script.js 或 /image.png 这样的资源请求会被发送到控制器进行处理，而不是仅仅返回这个资源。然后我觉得我没明白什么。我有两种方法，使用 <url-pattern>/blablabla/*</url-pattern> 之类的东西（当然没有将资源放在“blablabla”文件夹中）或任何请求的完全匹配（幸运的是，它们的数量有限）。现在又看到了，但是在spring boot项目中...
更新
正如@PiotrP.Karwasz 所建议的，我尝试按照 here 所示更改优先级。它产生了后果，但并没有解决问题。我创建了一个没有 Spring Security 的新项目。现在我的项目结构是这样的：
.

src/main/java/haven/MvcConfig.java：
package haven;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.format.support.FormattingConversionService;
import org.springframework.web.accept.ContentNegotiationManager;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;
import org.springframework.web.servlet.resource.ResourceUrlProvider;
@Configuration
public class MvcConfig extends WebMvcConfigurationSupport {
@Override
protected void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/**").addResourceLocations("classpath:/static/");
registry.setOrder(0);
}
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("home");
registry.addViewController("/home").setViewName("home");
registry.setOrder(1);
}
@Override
@Bean
public RequestMappingHandlerMapping requestMappingHandlerMapping(
ContentNegotiationManager contentNegotiationManager,
FormattingConversionService conversionService,
ResourceUrlProvider resourceUrlProvider) {
RequestMappingHandlerMapping handler = super.requestMappingHandlerMapping(
contentNegotiationManager,
conversionService,
resourceUrlProvider);
handler.setOrder(2);
return handler;
}
}
不再有没有参数的 requestMappingHandlerMapping 方法。我猜测新方法可能以类似的方式工作。也许我错了。
奇怪的是默认优先级是：
ResourceHandlerRegistry: Integer.MAX_VALUE - 1 = Ordered.LOWEST_PRECEDENCE - 1 = 2147483646
ViewControllerRegistry: 1
RequestMappingHandlerMapping: 0
RequestMappingHandlerMapping 没有字段 order，但在超类 AbstractHandlerMapping 中有
private int order = Ordered.LOWEST_PRECEDENCE; // default: same as non-Ordered
是2147483647。反正requestMappingHandlerMapping类中的WebMvcConfigurationSupport方法有一行
mapping.setOrder(0);
它的优先级高于 ResourceHandlerRegistry。
因此，实际上，默认情况下资源的优先级非常低。但不应该反过来吗？
但是，从现在开始我可以获取资源，但任何其他请求将始终返回 404 响应。即使对于 / 或 /home。但是，如果我将 ViewControllerRegistry 的优先级设置为大于或等于 ResourceHandlerRegistry，那么 / 和 /home 请求也将起作用，但不是所有其他请求。例如：
ResourceHandlerRegistry: 0
ViewControllerRegistry: 0 (or even -1!)
RequestMappingHandlerMapping: 1
如果我将 RequestMappingHandlerMapping 的优先级设置为高于或等于其他人会导致 readersBooks 方法处理任何请求时的原始问题。有一个例外：如果我发出请求 /style.css，标头将包含 Content-Type: text/css;charset=UTF-8，但正文将作为 reading-list.html 的内容。对于任何其他请求，响应是带有 reading-list.html 的 Content-Type: text/html;charset=UTF-8 的内容，因为它最初是在更改优先级之前。
我是这方面的完全新手。这个问题有简单的解决方案吗？我几乎完全确定，即使可以以某种方式正确设置优先级并处理请求，就像我现在尝试做的那样，也只能是“治标不治本”。
我已经设置了这样的优先级：
ResourceHandlerRegistry: 0
ViewControllerRegistry: 1
RequestMappingHandlerMapping: 2

我第二次这样设置优先级：
ResourceHandlerRegistry: 0
ViewControllerRegistry: 0
RequestMappingHandlerMapping: 1
除了对第二个和第三个请求的响应外，没有任何变化。似乎当一个资源具有最高优先级时，它会阻止其他人处理请求。
