SpringBoot2 - SpringSecurity

2018-06-26 本文已影响0人深入浅出

简介

SpringSecurity是专门针对基于Spring项目的安全框架，充分利用了依赖注入和AOP来实现安全管控。

SpringSecurity框架有两个概念认证和授权，认证可以访问系统的用户，而授权则是用户可以访问的资源。

创建接口

package com.gala.security.jpa;

import org.springframework.data.jpa.repository.JpaRepository;

import com.gala.security.entity.User;

public interface UserDao extends JpaRepository<User, Long> {

    public User findByUsername(String username);

}

SpringSecurity用户认证

密码加密

package com.gala.security;

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

public class MyPasswordEncoder implements PasswordEncoder {

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

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

认证配置

package com.gala.security.service;

import java.util.Collection;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
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.Service;

import com.gala.security.entity.User;
import com.gala.security.jpa.UserDao;

@Service
public class CustomUserDetailsService implements UserDetailsService {

    @Autowired
    private UserDao userDao;

    /**
     * 自定义用户登录
     */
    @SuppressWarnings("unchecked")
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userDao.findByUsername(username);
        if (user == null) {
            System.out.println("获取用户信息" + username + "失败");
            throw new UsernameNotFoundException("用户名：" + username + "不存在");
        }

        Collection<GrantedAuthority> authorities = (Collection<GrantedAuthority>) user.getAuthorities();

        user.setAuthorities(authorities);
        System.out.println("获取用户" + username + "信息成功！");
        return user;
    }
}

配置SpringBoot内的MVC控制器跳转

package com.gala.security.conf;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

/**
 * 配置SpringBoot内的MVC控制器跳转
 */
@Configuration
public class MVCConfig implements WebMvcConfigurer {

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/login").setViewName("login");
    }

}

新增控制器

package com.gala.security.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class LoginController {

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

}

新增JSP

登录页面

<%@ page contentType="text/html;charset=UTF-8" language="java"%>
<html>
<head>
<title>登录界面</title>
</head>
<body>
    <form action="/login" method="post">
        用户名：<input type="text" name="username" /><br />
        密码：<input type="text" name="password" /><br />
        <input type="submit" value="登录" />
    </form>
</body>
</html>

2.登录成功页面

<%@ page contentType="text/html;charset=UTF-8" language="java"%>
<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %>
<html>
<head>
