package com.yl.security.config;

import com.yl.security.handler.LogOutSuccessHandler;
import com.yl.security.handler.LoginFailHandler;
import com.yl.security.handler.LoginSuccessHandler;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true,securedEnabled = true) //开启全局方法安全功能
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    LoginSuccessHandler loginSuccessHandler;
    @Autowired
    LoginFailHandler loginFailHandler;
    @Autowired
    LogOutSuccessHandler logOutSuccessHandler;

    //使用不加密的编码方式
//    @Bean
//    PasswordEncoder passwordEncoder() {
//        return NoOpPasswordEncoder.getInstance();
//    }

    @Bean
    PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    // 基于内存的用户名和密码认证
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
       auth.inMemoryAuthentication()
               // 密码设置为123
               .withUser("root").password("$2a$10$O8G0X/sUPAA76MV7U3BwY.3Uo8/QMBcqK678Rwkoz.fowbce.CLtO").roles("user")
               .and().withUser("admin").password("$2a$10$O8G0X/sUPAA76MV7U3BwY.3Uo8/QMBcqK678Rwkoz.fowbce.CLtO").roles("admin");
    }

    //匹配拦截路径，处理器等
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/admin/**").hasRole("admin") //静态配置哪些角色访问才能访问指定路径

                .and()
                .csrf().disable(); //关闭csrf保护
    }
}

3.登录成功处理器

package com.yl.security.handler;

import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.stereotype.Component;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;
import java.util.Map;

//登录成功处理器
@Component
public class LoginSuccessHandler implements AuthenticationSuccessHandler {
    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
        response.setContentType("application/json;charset=utf-8");
        PrintWriter writer = response.getWriter();
        Map<String,Object> map = new HashMap<>();
        map.put("status",200);
        map.put("msg",authentication.getPrincipal());
        writer.write(new ObjectMapper().writeValueAsString(map));
        writer.flush();
        writer.close();
    }
}

4.登录失败处理器

package com.yl.security.handler;

import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.security.authentication.*;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.stereotype.Component;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;
import java.util.Map;

//登录失败处理器
@Component
public class LoginFailHandler implements AuthenticationFailureHandler {

    @Override
    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
        response.setContentType("application/json;charset=utf-8");
        PrintWriter writer = response.getWriter();
        Map<String,Object> map = new HashMap<>();
        map.put("code",401);
        if (exception instanceof LockedException) {
            map.put("msg","账户被锁定");
        } else if (exception instanceof BadCredentialsException) {
            map.put("msg","用户名或密码错误");
        } else if (exception instanceof DisabledException) {
            map.put("msg","账户被禁用");
        } else if (exception instanceof AccountExpiredException) {
            map.put("msg","账户过期");
        } else if (exception instanceof CredentialsExpiredException) {
            map.put("msg","密码过期");
        } else {
            map.put("msg","登录异常");
        }
        writer.write(new ObjectMapper().writeValueAsString(map));
        writer.flush();
        writer.close();
    }
}

5.登出成功处理器

package com.yl.security.handler;

import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.logout.LogoutSuccessHandler;
import org.springframework.stereotype.Component;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;
import java.util.Map;

@Component
public class LogOutSuccessHandler implements LogoutSuccessHandler {
    @Override
    public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
        response.setContentType("application/json;charset=utf-8");
        PrintWriter writer = response.getWriter();
        Map<String,Object> map = new HashMap<>();
        map.put("status",200);
        map.put("msg","注销成功");
        writer.write(new ObjectMapper().writeValueAsString(map));
        writer.flush();
        writer.close();
    }
}

6.全局方法安全功能

package com.yl.security.service;

import org.springframework.security.access.annotation.Secured;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.stereotype.Service;

@Service
public class MethodService {

    @PreAuthorize("hasRole('admin')")
    public String admin() {
        return "hello admin";
    }

    @Secured("ROLE_user")
    public String user() {
        return "hello user";
    }

    @PreAuthorize("hasAnyRole('admin','user')")
    public String hello() {
        return "hello hello";
    }
}

7.controller

package com.yl.security.controller;

import com.yl.security.service.MethodService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

    @Autowired
    MethodService methodService;

    @GetMapping("/hello")
    public String hello() {
        return "hello security";
    }

    @GetMapping("/admin/hello")
    public String admin() {
        return "hello admin";
    }

    @GetMapping("/user/hello")
    public String user() {
        return "hello user";
    }

    @GetMapping("/login")
    public String login() {
        return "please login";
    }

    @GetMapping("/hello1")
    public String hello1() {
        return methodService.admin();
    }

    @GetMapping("/hello2")
    public String hello2() {
        return methodService.user();
    }

    @GetMapping("/hello3")
    public String hello3() {
        return methodService.hello();
    }

}

8.测试

1.任何请求都要登录

2.登录成功后，会返回相关信息

3.能访问/user/hello

4.但是没权限访问/admin/hello

5.全局方法安全的测试
1）root用户能访问/hello2

2)但是root用户不能访问/hello1

9.配置多个httpsecurityconfig,使用内部类

package com.yl.security.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
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.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

// 多个httpSecurity的配置，使用静态内部类
@Configuration
public class MultiHttpSecurityConfig {
    @Bean
    PasswordEncoder passwordEncoder() {
        return NoOpPasswordEncoder.getInstance();
    }

    @Autowired
    // 配置静态的用户名和密码
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("root").password("111").roles("user")
                .and().withUser("admin").password("222").roles("admin");
    }

    @Configuration
    @Order(1) // 设置优先级，数字越小，优先级越高
    public static class AdminSecurityConfig extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.antMatcher("/admin/**").authorizeRequests().anyRequest().hasAnyRole("admin");
        }
    }

    @Configuration
    public static class OtherSecurityConfig extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.authorizeRequests().anyRequest().authenticated()
                    .and()
                    .formLogin()
                    .loginProcessingUrl("/doLogin")
                    .permitAll()
                    .and()
                    .csrf().disable();
        }
    }
}
