springboot_springsecurity: springboot 整合spring security

springboot 整合 Spring Security

第一步:加入依赖

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

一旦引入这个依赖，spring boot项目就默认开启了 security的默认保护。访问任何请求都会跳转到/login ，默认显示一个登录页面，但是我们并不知道用户名和密码。

用户名默认是user，密码是加密的在运行后台可以找到，默认是打印到后来的。

第二步：java 配置类

package com.young.security.mysecurity.config;

import com.young.security.mysecurity.security.MyUserDetailService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
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;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;
import org.springframework.security.web.authentication.rememberme.PersistentTokenRepository;

import javax.sql.DataSource;

/**

 * Convertion over Configuration!
 */
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true,jsr250Enabled = true,prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private DataSource dataSource;
    @Autowired
    private MyUserDetailService myUserDetailService;
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        //1.启用内存用户存储
//        auth.inMemoryAuthentication()
//                .withUser("xfy").password(passwordEncoder().encode("1234")).roles("ADMIN").and()
//                .withUser("tom").password(passwordEncoder().encode("1234")).roles("USER");
        //2.基于数据库表进行验证
//        auth.jdbcAuthentication().dataSource(dataSource)
//                .usersByUsernameQuery("select username,password,enabled from user where username = ?")
//                .authoritiesByUsernameQuery("select username,rolename from role where username=?")
//                .passwordEncoder(passwordEncoder());
        //3.配置自定义的用户服务
        auth.userDetailsService(myUserDetailService);
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin().loginPage("/signIn").loginProcessingUrl("/user/userLogin")  //自定义登录页面、登录请求路由
                .and()
                .logout().logoutSuccessUrl("/signIn")// 设置登出，登出成功后跳转到登录页面
                .and()
                .authorizeRequests()  //开始请求的配置
                .antMatchers("/signIn","/hello").permitAll()  //  premitAll()不做拦截
                .antMatchers("/index").authenticated()   //authenticated()  必须登录后可见
                .antMatchers("/demo").permitAll()
                .antMatchers("/admin/**","/add").hasRole("ADMIN")  //有ADMIN角色
                .regexMatchers("/admin1/.*").access("hasRole('ADMIN') or hasRole('ADMIN1')")
                .anyRequest().authenticated()
                .and()
                .requiresChannel().antMatchers("/add").requiresSecure()//https://127.0.0.1:8443/add    将http转为https
                .and()
                .rememberMe().tokenValiditySeconds(2419200).tokenRepository(persistentTokenRepository()).alwaysRemember(true);// 启用记住我

    }

//    记住我，将用户信息存入数据库
    @Bean
    public PersistentTokenRepository persistentTokenRepository() {
        JdbcTokenRepositoryImpl tokenRepository = new JdbcTokenRepositoryImpl();
        tokenRepository.setDataSource(dataSource);
        //tokenRepository.setCreateTableOnStartup(true);
        return tokenRepository;
    }


//注册密码加密处理器
    @Bean
    public static PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

}

自定义UserDetailsService

package com.young.security.mysecurity.security;

import com.young.security.mysecurity.pojo.Role;
import com.young.security.mysecurity.pojo.User;
import com.young.security.mysecurity.repository.RoleRepository;
import com.young.security.mysecurity.repository.UserRepository;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AuthenticationCredentialsNotFoundException;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;

import java.util.ArrayList;
import java.util.List;

/**
 * Create by stefan
 * Date on 2018-05-17  22:49
 * Convertion over Configuration!
 */
@Component
@Slf4j
public class MyUserDetailService implements UserDetailsService {
    @Autowired
    private PasswordEncoder passwordEncoder;
    @Autowired
    UserRepository userRepository;
    @Autowired
    private RoleRepository roleRepository;
    @Override
    public UserDetails loadUserByUsername(String name) throws UsernameNotFoundException {
        User user = userRepository.findByUsername(name);
        if (user==null){
            throw new AuthenticationCredentialsNotFoundException("authError");
        }
        log.info("{}",user);
        List<Role> role = roleRepository.findByUsername(name);
        log.info("{}",role);
        List<GrantedAuthority> authorities = new ArrayList<>();
        role.forEach(role1 -> authorities.addAll(AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_"+role1.getRolename())));
        log.info("{}",authorities);
        return new org.springframework.security.core.userdetails.User(user.getUsername(),user.getPassword(),authorities);
    }
}

使用注解保护

开启注解

@EnableGlobalMethodSecurity(securedEnabled = true,jsr250Enabled = true,prePostEnabled = true)

注解示意：

@Secured({"ADMIN","ADMIN1"})
@RolesAllowed({"ADMIN","ADMIN1"})

使用方式相似，RolesAllowed更正式

@PreAuthorize("hasRole('ADMIN') AND hasRole('ADMIN1')")  的string参数是一个SpEL表达式
@PreAuthorize("hasRole('ADMIN') and #user.username.length() <=6") 可获得参数
@PostAuthorize("returnObject.username == principal.username")  可获得返回值

过滤方法

@PostFilter("hasRole('ADMIN') || filterObject.username == principal.username")   这个可直接获得方法的返回值列表的单个元素filterObject，不需要加#
@PreFilter("hasRole('ADMIN') || #filterObject.endsWith('admin')")  加#filterObject可获得传入参数列表的单个元素

视图保护（Thymeleaf）

第一步：引入依赖

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

<dependency>
	<groupId>org.thymeleaf.extras</groupId>
	<artifactId>thymeleaf-extras-springsecurity4</artifactId>
</dependency>

第二步：在视图页声明：

<html xmlns:th="http://www.thymeleaf.org" xmlns:sec="http://www.thymeleaf.org/extras/spring-security">

第三步使用：

<div sec:authorize="isAuthenticated()"> <!--sec:authorize属性会接受一个SpEL表达式  isAuthenticated() 只有用户已经进行认证了，才会渲染出内容。 -->
    hello <span sec:authentication="name">someone</span> !
</div>
<form th:action="@{/logout}" method="post">
    <input type="submit" value="注销"/>
</form>

<div sec:authorize="hasRole('ADMIN')">
    会员admin可见
</div>

<div sec:authorize="hasRole('ADMIN') or hasRole('ADMIN1')">
    会员admin\ADMIN1可见
</div>

<span sec:authorize-url="/admin/center">
    <a th:href="@{/admin/center}">admin中心</a>
</span>

<span sec:authorize-url="/admin1/index">
    <a th:href="@{/admin1/index}">admin1中心</a>
</span>
