springSecurity的ssm配置和springBoot配置

一. ssm配置
1.首先在web.xml文件中配置过滤器和监听器

contextConfigLocation
classpath:spring-security.xml


org.springframework.web.context.ContextLoaderListener


springSecurityFilterChain
org.springframework.web.filter.DelegatingFilterProxy


springSecurityFilterChain
/*

2.在resources文件夹下创建spring-security配置文件,还要创建验证用户名密码的方法

@Service("userService")
@Transactional(rollbackFor = Exception.class)
public class UserServiceImpl implements IUserService {


    private final IUserDao userDao;

    private final BCryptPasswordEncoder bCryptPasswordEncoder;

    @Autowired
    public UserServiceImpl(IUserDao userDao, BCryptPasswordEncoder bCryptPasswordEncoder) {
        this.userDao = userDao;
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    }

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {

        UserInfo userInfo;
        User user=null;
        try {
            userInfo = userDao.findByUsername(username);

            if (userInfo!=null) {
                user = new User(userInfo.getUsername(), userInfo.getPassword(), userInfo.getStatus() != 0,
                        true, true, true, getAuthority(userInfo.getRoles()));
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        return user;


    }

    private List getAuthority(List roles){
        List list=new ArrayList<>();
        for (Role role : roles) {
            list.add(new SimpleGrantedAuthority("ROLE_"+role.getRoleName()));
        }
        return list;
    }

这是使用加密类的配置方式,如果不使用加密类,可把替换成如下所示,
注意：使用springsecurity5，需要加上{noop}指定使用NoOpPasswordEncoder给DelegatingPasswordEncoder去校验密码,这样我们再配置前端登录就可以了

二.springBoot配置
1.springBoot配置起来就简单许多了,我们先配置一个不加密的

package com.logoxiang.config;

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.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.User;

/**
 * @Author: logoxiang
 * @Date: 2019/2/14 9:21
 */
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    /**
     * 配置拦截器保护请求
     * @param http
     * @throws Exception
     */
    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.headers().frameOptions().sameOrigin().and().csrf() .disable().authorizeRequests()

                .antMatchers("/admin/**").hasRole("USER")/*与之匹配的请求/用户/*要求对用户进行身份验证，并且必须与用户角色*/
                .anyRequest().permitAll().and().
                formLogin()
                .loginPage("/login.html").loginProcessingUrl("/denglu").
                defaultSuccessUrl("/admin/index.html").failureUrl("/login.html").and().logout().logoutSuccessUrl("/login.html");
    }

    /**
     * 配置user-detail服务
     * @param auth
     * @throws Exception
     */
    @Autowired
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication().passwordEncoder(new MyPasswordEncoder())
                .withUser("logoxiang").password("1234").roles("USER");
    }
}

public class MyPasswordEncoder implements PasswordEncoder {

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

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

2.再配置一个加密的:

@Component
public class UserDetailsConfig  implements UserDetailsService {
    @Autowired
    private SellerService sellerService;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException{

        List grantAuths = new ArrayList();
        grantAuths.add(new SimpleGrantedAuthority("USER"));

        TbSeller seller = sellerService.findOne(username);
        if(seller != null){
            if(seller.getStatus().equals("1")){
                return new User(username,seller.getPassword(),grantAuths );
            }else{
                return null;

            }
        }
        return null ;

    }
}

@Configuration
public class BcryptEncoderConfig {
    @Bean
    public BCryptPasswordEncoder createB(){
        return new BCryptPasswordEncoder();
    }
}

这个我写的有点不完善,待更
