**二 启动类**

package org.fkit.securitytest;
    
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    
    //@SpringBootApplication指定这是一个 spring boot的应用程序.
    @SpringBootApplication
    public class App
    {
        public static void main( String[] args )
        {
            // SpringApplication 用于从main方法启动Spring应用的类。
            SpringApplication.run(App.class, args);
        }
    }

**三 控制器**

package org.fkit.securitytest.controller;
    
    
    import java.util.ArrayList;
    import java.util.List;
    
    
    import javax.servlet.http.HttpServletRequest;

    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    
    @Controller
    public class AppController {
    
    
        @RequestMapping("/")

            // Authentication是一个接口，表示用户认证信息
            Authentication auth = SecurityContextHolder.getContext().getAuthentication();
            // 如果用户认知信息不为空，注销
            if (auth != null) {
                new SecurityContextLogoutHandler().logout(request, response, auth);
            }
            // 重定向到login页面
            return "redirect:/login?logout";

         * 获得当前用户名称
         */

            String username = SecurityContextHolder.getContext().getAuthentication().getName();
            System.out.println("username = " + username);
            return username;
        }
    
    
        /**
         * 获得当前用户权限
         */
        private String getAuthority() {
            // 获得Authentication对象，表示用户认证信息。
            Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
            List<String> roles = new ArrayList<String>();
            // 将角色名称添加到List集合
            for (GrantedAuthority a : authentication.getAuthorities()) {

            return roles.toString();
        }

**四 认证处理类**

1 MyPasswordEncoder

    import  org.springframework.security.crypto.password.PasswordEncoder;
    public class MyPasswordEncoder implements PasswordEncoder{
         
         @Override

               return arg1.equals(arg0.toString());
         }
    }

2 AppAuthenticationSuccessHandler

package org.fkit.securitytest.security;
    import java.io.IOException;
    import java.util.ArrayList;
    import java.util.Collection;
    import java.util.List;
    import javax.servlet.http.HttpServletRequest;

    import org.springframework.security.web.RedirectStrategy;
    import  org.springframework.security.web.authentication.SimpleUrlAuthenticationSuccessHandler;
    import org.springframework.stereotype.Component;
    @Component
    public class AppAuthenticationSuccessHandler extends  SimpleUrlAuthenticationSuccessHandler {
         // Spring Security 通过RedirectStrategy对象负责所有重定向事务
         private RedirectStrategy redirectStrategy = new  DefaultRedirectStrategy();
         /*
          * 重写handle方法，方法中通过RedirectStrategy对象重定向到指定的url
          */
         @Override
         protected void handle(HttpServletRequest request,  HttpServletResponse response, Authentication authentication)
                    throws IOException {
               // 通过determineTargetUrl方法返回需要跳转的url
               String targetUrl =  determineTargetUrl(authentication);
               // 重定向请求到指定的url
               redirectStrategy.sendRedirect(request, response,  targetUrl);
         }
         /*
          * 从Authentication对象中提取角色提取当前登录用户的角色，并根据其角色返回适当的URL。
          */
         protected String determineTargetUrl(Authentication  authentication) {
               String url = "";
               // 获取当前登录用户的角色权限集合
               Collection<? extends GrantedAuthority> authorities =  authentication.getAuthorities();
               List<String> roles = new ArrayList<String>();
               // 将角色名称添加到List集合
               for (GrantedAuthority a : authorities) {
                    roles.add(a.getAuthority());
               }
               // 判断不同角色跳转到不同的url
               if (isAdmin(roles)) {
                    url = "/admin";
               } else if (isUser(roles)) {
                    url = "/home";
               } else {
                    url = "/accessDenied";
               }
               System.out.println("url = " + url);
               return url;
         }
         private boolean isUser(List<String> roles) {
               if (roles.contains("ROLE_USER")) {
                    return true;
               }
               return false;

                    return true;
               }
               return false;
         }
         public void setRedirectStrategy(RedirectStrategy  redirectStrategy) {
               this.redirectStrategy = redirectStrategy;
         }
         protected RedirectStrategy getRedirectStrategy() {
               return redirectStrategy;
         }
    }

3 AppSecurityConfigurer

package org.fkit.securitytest.security;
    
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;

    @Configuration
    public class AppSecurityConfigurer extends WebSecurityConfigurerAdapter {
    
    
        /**
         * 注入认证处理类，处理不同用户跳转到不同的页面
         */
        @Autowired
        AppAuthenticationSuccessHandler appAuthenticationSuccessHandler;
    
    
        /**
         * 用户授权操作
         */
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            System.out.println("AppSecurityConfigurer configure() HttpSecurity 调用......");
            http.authorizeRequests()
                    // spring-security 5.0 之后需要过滤静态资源
                    .antMatchers("/login", "/css/**", "/js/**", "/img/*").permitAll().antMatchers("/", "/home")
                    .hasRole("USER").antMatchers("/admin/**").hasAnyRole("ADMIN", "DBA").anyRequest().authenticated().and()
                    .formLogin().loginPage("/login").successHandler(appAuthenticationSuccessHandler)
                    .usernameParameter("loginName").passwordParameter("password").and().logout().permitAll().and()
                    .exceptionHandling().accessDeniedPage("/accessDenied");
        }
    
    
        /**
         * 用户认证操作
         */
        @Autowired
        public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
            System.out.println("AppSecurityConfigurer configureGlobal() 调用......");
            // spring-security 5.0 之后需要密码编码器，否则会抛出异常：There is no PasswordEncoder mapped for
            // the id "null"
            auth.inMemoryAuthentication().passwordEncoder(new MyPasswordEncoder()).withUser("fkit").password("123456")
                    .roles("USER");
            auth.inMemoryAuthentication().passwordEncoder(new MyPasswordEncoder()).withUser("admin").password("admin")
                    .roles("ADMIN", "DBA");
        }
    
    
    }
