如果在类路径上添加了Spring Boot Security依赖项，则Spring Boot应用程序会自动为所有HTTP端点提供基本身份验证。端点“/”和“/home”不需要任何身份验证。所有其他端点都需要身份验证。
要将Spring Boot Security添加到Spring Boot应用程序，需要在构建配置文件中添加Spring Boot Starter Security依赖项。
Maven用户可以在pom.xml 文件中添加以下依赖项。
<dependency>
<groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> Gradle用户可以在build.gradle 文件中添加以下依赖项。
compile("org.springframework.boot:spring-boot-starter-security")
保护Web应用程序
首先，使用Thymeleaf模板创建不安全的Web应用程序。
然后，在 src/main/resources/templates 目录下创建一个home.html 文件。
<!DOCTYPE html>
<html xmlns = "http://www.w3.org/1999/xhtml"
xmlns:th = "http://www.thymeleaf.org"
xmlns:sec = "http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
<head> <title>Spring Security示例</title> </head> <body> <h1>欢迎您!</h1> <p>点击 <a th:href = "@{/hello}">这里</a> 看到问候语.</p> </body> </html> 使用Thymeleaf模板在HTML文件中定义的简单视图/hello。现在，在src/main/resources/templates目录下创建一个文件:hello.html。
<!DOCTYPE html>
<html xmlns = "http://www.w3.org/1999/xhtml"
xmlns:th = "http://www.thymeleaf.org"
xmlns:sec = "http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
<head> <title>Hello World!</title> </head> <body> <h1>Hello world!</h1> </body> </html> 现在，需要为Home和hello视图设置Spring MVC - View控制器。为此，创建一个扩展WebMvcConfigurerAdapter的MVC配置文件。
package com.yiibai.websecuritydemo;
import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.ViewControllerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; @Configuration public class MvcConfig extends WebMvcConfigurerAdapter { @Override public void addViewControllers(ViewControllerRegistry registry) { registry.addViewController("/home").setViewName("home"); registry.addViewController("/").setViewName("home"); registry.addViewController("/hello").setViewName("hello"); registry.addViewController("/login").setViewName("login"); } } 现在，将Spring Boot Starter安全依赖项添加到构建配置文件中。Maven用户可以在pom.xml 文件中添加以下依赖项。
<dependency>
<groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> Gradle用户可以在build.gradle 文件中添加以下依赖项。
compile("org.springframework.boot:spring-boot-starter-security")
现在，创建一个Web安全配置文件，该文件用于保护应用程序以使用基本身份验证访问HTTP端点。
package com.yiibai.websecuritydemo;
import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Configuration; import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; @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(); } @Autowired public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { auth .inMemoryAuthentication() .withUser("user").password("password").roles("USER"); } } 现在，在src/main/resources 目录下创建一个login.html 文件，以允许用户通过登录屏幕访问HTTP端点。
<!DOCTYPE html>
<html xmlns = "http://www.w3.org/1999/xhtml" xmlns:th = "http://www.thymeleaf.org"
xmlns:sec = "http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
<head> <title>Spring Security示例</title> </head> <body> <div th:if = "${param.error}"> 无效的用户名和密码. </div> <div th:if = "${param.logout}"> 你已经注销. </div> <form th:action = "@{/login}" method = "post"> <div> <label> 用户名 : <input type = "text" name = "username"/> </label> </div> <div> <label> 密码: <input type = "password" name = "password"/> </label> </div> <div> <input type = "submit" value = "登录"/> </div> </form> </body> </html> 最后，更新hello.html 文件 - 允许用户从应用程序注销并显示当前用户名，如下所示 -
<!DOCTYPE html>
<html xmlns = "http://www.w3.org/1999/xhtml" xmlns:th = "http://www.thymeleaf.org"
xmlns:sec = "http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
<head> <title>Hello World!</title> </head> <body> <h1 th:inline = "text">您好，[[${#httpServletRequest.remoteUser}]]!</h1> <form th:action = "@{/logout}" method = "post"> <input type = "submit" value = "注销"/> </form> </body> </html> 主 Spring Boot应用程序的代码如下 -
package com.yiibai.websecuritydemo;
import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class WebsecurityDemoApplication { public static void main(String[] args) { SpringApplication.run(WebsecurityDemoApplication.class, args); } } 下面给出了构建配置文件的完整代码。
Maven构建文件 - pom.xml 的内容如下:
<?xml version = "1.0" encoding = "UTF-8"?>
