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对所有HTTP端点进行基本身份验证.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.
为了向Spring Boot应用程序添加Spring Boot Security,我们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")
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 下创建一个home.html文件目录.
<!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,我们需要为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.it1352.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,即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.it1352.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 下创建一个login.html文件允许用户通过登录屏幕访问HTTP端点的目录.
<!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>
主要Spring Boot应用程序的代码在下面和下面给出;
package com.it1352.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 - pom.xml
<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.IT屋</groupId> <artifactId>websecurity-demo</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>websecurity-demo</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-test</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
Gradle - 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.it1352' 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,使用以下Maven或Gradle命令运行Spring Boot应用程序.
Maven用户可以使用下面给出的命令 :
mvn clean install
在"BUILD SUCCESS"之后,你可以在目标目录下找到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,您可以在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>
在网络浏览器中点击网址 http://localhost:8080/.您可以看到输出如图所示.
