• Spring Boot 5 SpringSecurity身份验证


    对于没有访问权限的用户需要转到登录表单页面。要实现访问控制的方法多种多样,可以通过Aop、拦截器实现,也可以通过框架实现(如:Apache Shiro、Spring Security)。

    pom.xml添加依赖

    <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</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-security</artifactId>
            </dependency>

    创建SpringSecurity配置类

    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.EnableWebSecurity;
    import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
    
    @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("admin").password("123456").roles("USER");
        }
    }

    通过@EnableWebSecurity注解开启Spring Security的功能
    继承WebSecurityConfigurerAdapter,并重写它的方法来设置一些web安全的细节
    configure(HttpSecurity http)方法,通过authorizeRequests()定义哪些URL需要被保护、哪些不需要被保护。例如以上代码指定了/和/home不需要任何认证就可以访问,其他的路径都必须通过身份验证。
    通过formLogin()定义当需要用户登录时候,转到的登录页面。
    configureGlobal(AuthenticationManagerBuilder auth)方法,在内存中创建了一个用户,该用户的名称为admin,密码为123456,用户角色为USER。

    控制器:

    @Controller
    public class HelloController {
    
        @RequestMapping("/")
        public String index() {
            return "index";
        }
    
        @RequestMapping("/hello")
        public String hello() {
            return "hello";
        }
    
        @RequestMapping(value = "/login", method = RequestMethod.GET)
        public String login() {
            return "login";
        }
    
    }

    index.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>Spring Security入门</title>
    </head>
    <body>
    <h1>欢迎使用Spring Security!</h1>
    
    <p>点击 <a th:href="@{/hello}">这里</a> 打个招呼吧</p>
    </body>
    </html>

    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>

    </head>
    <body>
    <h1 th:inline="text">Hello [[${#httpServletRequest.remoteUser}]]!</h1>
    <form th:action="@{/logout}" method="post">
        <input type="submit" value="注销"/>
    </form>
    </body>
    </html>

    login.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>Spring Security Example </title>
    </head>
    <body>
    <div th:if="${param.error}">
        用户名或密码错
    </div>
    <div th:if="${param.logout}">
        您已注销成功
    </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>

    运行:

    打开index.html,点击这里,如果没有登录进入登录页,已登录跳转到hello.html
