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"?>
