pom.xml添加依赖
1 <dependency> 2 <groupId>org.springframework.boot</groupId> 3 <artifactId>spring-boot-starter-web</artifactId> 4 </dependency> 5 6 <dependency> 7 <groupId>org.springframework.boot</groupId> 8 <artifactId>spring-boot-starter-thymeleaf</artifactId> 9 </dependency> 10 <dependency> 11 <groupId>org.springframework.boot</groupId> 12 <artifactId>spring-boot-starter-security</artifactId> 13 </dependency>
创建SpringSecurity配置类
1 import org.springframework.beans.factory.annotation.Autowired; 2 import org.springframework.context.annotation.Configuration; 3 import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder; 4 import org.springframework.security.config.annotation.web.builders.HttpSecurity; 5 import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; 6 import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; 7 8 @Configuration 9 @EnableWebSecurity 10 public class WebSecurityConfig extends WebSecurityConfigurerAdapter { 11 12 @Override 13 protected void configure(HttpSecurity http) throws Exception { 14 http 15 .authorizeRequests() 16 .antMatchers("/", "/home").permitAll() 17 .anyRequest().authenticated() 18 .and() 19 .formLogin() 20 .loginPage("/login") 21 .permitAll() 22 .and() 23 .logout() 24 .permitAll(); 25 } 26 27 @Autowired 28 public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { 29 //inMemoryAuthentication 从内存中获取 30 auth 31 .inMemoryAuthentication() 32 .passwordEncoder(new BCryptPasswordEncoder()) 33 .withUser("admin") 34 .password(new BCryptPasswordEncoder() 35 .encode("123456")).roles("USER"); 36 } 37 }
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：
1 @Controller 2 public class HelloController { 3 4 @RequestMapping("/") 5 public String index() { 6 return "index"; 7 } 8 9 @RequestMapping("/hello") 10 public String hello() { 11 return "hello"; 12 } 13 14 @RequestMapping(value = "/login", method = RequestMethod.GET) 15 public String login() { 16 return "login"; 17 } 18 19 }

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
