Spring Boot - Web安全应用

如果在类路径上添加了Spring Boot Security依赖项，则Spring Boot应用程序会自动要求所有HTTP端点都使用基本身份验证。端点" /"和"/home"不需要任何身份验证。

为了向您的Spring Boot应用程序添加Spring Boot Security，无涯教程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")

Web应用程序

首先，使用Thymeleaf模板创建一个不安全的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 Example</title>
   </head>
   <body>
      <h1>Welcome!</h1>
      <p>Click <a th:href="@{/hello}">here</a> to see a greeting.</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，无涯教程需要为主视图和问候视图设置Spring MVC – View控制器。

为此，创建一个扩展WebMvcConfigurerAdapter的MVC配置文件。

package com.learnfk.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安全依赖项添加到您的构建配置文件中。

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，该文件用于保护您的应用程序通过使用基本身份验证来访问HTTP端点。

package com.learnfk.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 Example </title>
   </head>
   <body>
      <div th:if="${param.error}">
         Invalid username and password.
      </div>
      <div th:if="${param.logout}">
         You have been logged out.
      </div>
      
      <form th:action="@{/login}" method="post">
         <div>
            <label> User Name : <input type="text" name="username"/> </label>
         </div>
         <div>
            <label> Password: <input type="password" name="password"/> </label>
         </div>
         <div>
            <input type="submit" value="Sign In"/>
         </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">Hello [[${#httpServletRequest.remoteUser}]]!</h1>
      <form th:action="@{/logout}" method="post">
         <input type="submit" value="Sign Out"/>
      </form>
   </body>
   
</html>

下面给出了主要的Spring Boot应用程序的代码-

package com.learnfk.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);
   }
}
