我們要關注的地方用紅框標記出來了。
1、首先要在pom.xml中引入相應的靜態資源jar
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.4.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.gong</groupId> <artifactId>springboot-curd</artifactId> <version>0.0.1-SNAPSHOT</version> <name>springboot-curd</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.webjars</groupId> <artifactId>bootstrap</artifactId> <version>4.1.2</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
我們可以在External Libraries下找相應的jar，並查看里面的目錄結構：比如
在/resources/webjars/bootstrap/4.1.2/ css下有bootstrap.css，這為我們以后在html文件中引入靜態資源提供了基礎。
2、配置自己定義的springmvc配置
在config/MyMvcConfig.java中
package com.gong.springbootcurd.config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.EnableWebMvc; import org.springframework.web.servlet.config.annotation.ViewControllerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; //@EnableWebMvc 接管springmvc @Configuration public class MyMvcConfig implements WebMvcConfigurer{ @Override public void addViewControllers(ViewControllerRegistry registry) { //瀏覽器發送gong請求會跳轉到/templates/success.html頁面 //測試用的 registry.addViewController("gong").setViewName("success"); } //所有的WebMvcConfigurer會一起起作用 //將組件注冊到容器中 @Bean public WebMvcConfigurer webMvcConfigurer() { WebMvcConfigurer webMvcConfigurer = new WebMvcConfigurer(){ public void addViewControllers(ViewControllerRegistry registry) { registry.addViewController("/").setViewName("login"); registry.addViewController("/login.html").setViewName("login"); } }; return webMvcConfigurer; } }
當服務器啟動或發送login.html請求時跳轉到/templates/login.html頁面
3、在主配置文件中定義項目的名稱
server.servlet.context-path=/curd
這樣啟動后，在瀏覽器訪問請求時就需要帶上這個名稱。
4、login.html
<!DOCTYPE html> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <meta name="description" content=""> <meta name="author" content=""> <title>Signin Template for Bootstrap</title> <!-- Bootstrap core CSS --> <link href="asserts/css/bootstrap.min.css" th:href="@{/webjars/bootstrap/4.1.2/css/bootstrap.css}" rel="stylesheet"> <!-- Custom styles for this template --> <link href="asserts/css/signin.css" th:href="@{/asserts/css/signin.css}" rel="stylesheet"> </head> <body class="text-center"> <form class="form-signin" action="dashboard.html" th:action="@{/user/login}" method="post"> <img class="mb-4" th:src="@{/asserts/img/bootstrap-solid.svg}" src="asserts/img/bootstrap-solid.svg" alt="" width="72" height="72"> <h1 class="h3 mb-3 font-weight-normal" >Please sign in</h1> <label class="sr-only" >Username</label> <input type="text" name="username" class="form-control" placeholder="Username"required="" autofocus=""> <label class="sr-only" >Password</label> <input type="password" name="password" class="form-control" placeholder="Password" required=""> <div class="checkbox mb-3"> <label> <input type="checkbox" value="remember-me"/> Remember me </label> </div> <button class="btn btn-lg btn-primary btn-block" type="submit" >Sign in</button> <p class="mt-5 mb-3 text-muted">© 2017-2018</p> <a class="btn btn-sm" th:href="@{/index.html(l='zh_CN')}">中文</a> <a class="btn btn-sm" th:href="@{/index.html(l='en_US')}">English</a> </form> </body> </html>
我們就可以使用thymeleaf的th:href="@{}"來引用jar格式的和文本格式的靜態資源了。具體css就不展示了。
5、啟動服務器，輸入localhost:8080/curd/
成功跳轉到login.html頁面。
