Spring Boot保护Web 基于Spring Boot保护Web应用程序

borter 人气:0

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>

XML

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>

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>

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");
  }
}

Java

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>

XML

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");
  }
}

Java

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>

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>

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);
  }
}

Java

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"?>
<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

     <plugin>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-maven-plugin</artifactId>
     </plugin>
   </plugins>
  </build>

</project>

XML

Gradle构建文件 – build.gradle

buildscript {
  ext {
   springBootVersion = ‘1.5.9.RELEASE‘
  }
  repositories {
   mavenCentral()
  }
  dependencies {
   classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
  }
}

apply plugin: ‘java‘
apply plugin: ‘eclipse‘
apply plugin: ‘org.springframework.boot‘

group = ‘com.yiibai‘
version = ‘0.0.1-SNAPSHOT‘
sourceCompatibility = 1.8

repositories {
  mavenCentral()
}
dependencies {
  compile(‘org.springframework.boot:spring-boot-starter-security‘)
  compile(‘org.springframework.boot:spring-boot-starter-thymeleaf‘)
  compile(‘org.springframework.boot:spring-boot-starter-web‘)

  testCompile(‘org.springframework.boot:spring-boot-starter-test‘)
  testCompile(‘org.springframework.security:spring-security-test‘)
}

现在,创建一个可执行的JAR文件,并使用以下Maven或Gradle命令运行Spring Boot应用程序。

Maven用户请使用下面给出的命令 -

mvn clean install

Shell

在“BUILD SUCCESS”之后,可以在target目录下找到JAR文件。
Gradle用户可以使用如下所示的命令 -

gradle clean build

在“BUILD SUCCESSFUL”之后,可以在build/libs 目录下找到JAR文件。

现在,使用下面显示的命令运行JAR文件 -

java –jar <JARFILE>
