1、SpringSecurityConfig（security配置）

// 手动定义用户认证 和 // 关联用户Service认证 二者取一

这里测试用的是 手动定义用户认证！！！

package com.jack.demo;

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.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

/**
 * @program: demo
 * @description: Security 配置
 * @author: Jack.Fang
 * @date:2020-06-01 1541
 **/

@Configuration
@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {

  @Autowired
  private MyUserService myUserService;

  @Override
  protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    // 手动定义用户认证
    auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder()).withUser("admin").password(new BCryptPasswordEncoder().encode("123456")).roles("ADMIN");
    auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder()).withUser("jack").password(new BCryptPasswordEncoder().encode("fang")).roles("USER");

    // 关联用户Service认证
    //auth.userDetailsService(myUserService).passwordEncoder(new MyPasswordEncoder());

    // 默认jdbc认证
    // auth.jdbcAuthentication().usersByUsernameQuery("").authoritiesByUsernameQuery("").passwordEncoder(new MyPasswordEncoder());
  }

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests()
        .antMatchers("/").permitAll()
        .anyRequest().authenticated()
        .and()
        .logout().permitAll()
        .and()
        .formLogin();
    http.csrf().disable();
  }

  @Override
  public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/js/**","/css/**","/image/**");
  }
}

2、MyPasswordEncoder（自定义密码比较）

package com.jack.demo;

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

/**
 * @program: demo
 * @description: 密码加密
 * @author: Jack.Fang
 * @date:2020-06-01 1619
 **/
public class MyPasswordEncoder implements PasswordEncoder {

  @Override
  public String encode(CharSequence charSequence) {
    return new BCryptPasswordEncoder().encode(charSequence.toString());
  }

  @Override
  public boolean matches(CharSequence charSequence, String s) {
    return new BCryptPasswordEncoder().matches(charSequence,s);
  }
}

3、MyUserService（自行实现的用户登录接口）

具体内容 省略。这里测试用的是SpringSecurityConfig手动添加用户名与密码。

package com.jack.demo;

import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Component;

/**
 * @program: demo
 * @description: 用户
 * @author: Jack.Fang
 * @date:2020-06-01 1617
 **/
@Component
public class MyUserService implements UserDetailsService {

  @Override
  public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
    return null;
  }
}

4、启动类（测试）

DemoApplication.java

package com.jack.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.security.access.prepost.PostAuthorize;
import org.springframework.security.access.prepost.PostFilter;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.security.access.prepost.PreFilter;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.core.userdetails.User;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@EnableGlobalMethodSecurity(prePostEnabled = true)
@RestController
@SpringBootApplication
public class DemoApplication {

	public static void main(String[] args) {
		SpringApplication.run(DemoApplication.class, args);
	}

	@RequestMapping("/")
	public String index(){
		return "hello Spring Security!";
	}

	@RequestMapping("/hello")
	public String hello(){
		return "hello !";
	}

	@PreAuthorize("hasRole('ROLE_ADMIN')")
	@RequestMapping("/roleAdmin")
	public String role() {
		return "admin auth";
	}


	@PreAuthorize("#id<10 and principal.username.equals(#username) and #user.username.equals('abc')")
	@PostAuthorize("returnObject%2==0")
	@RequestMapping("/test")
	public Integer test(Integer id, String username, User user) {
		// ...
		return id;
	}

	@PreFilter("filterObject%2==0")
	@PostFilter("filterObject%4==0")
	@RequestMapping("/test2")
	public List<Integer> test2(List<Integer> idList) {
		// ...
		return idList;
	}
}

测试hello接口（http://localhost:8080/hello）

未登录跳转登录页

登录SpringSecurityConfig配置的admin账号与密码123456
成功调用hello

测试roleAdmin（登录admin 123456成功，登录jack fang访问则失败）

登出 logout
