使用Basic认证模式

1、maven依赖

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

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

2、SecurityConfig 配置类

@Component
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    /**
     * 添加授权账户
     *
     * @param auth
     * @throws Exception
     */
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        // 设置用户账号信息和权限
        auth.inMemoryAuthentication().withUser("kaico_admin").password("kaico")
                .authorities("/");
        // 如果kaico_admin账户权限的情况 所有的接口都可以访问，如果kaico_add 只能访问addMember
        auth.inMemoryAuthentication().withUser("kaico_add").password("kaico")
                .authorities("/");
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //配置httpBasic Http协议认证
        http.authorizeRequests().antMatchers("/**").fullyAuthenticated().and().httpBasic();
    }
    /**
     * There is no PasswordEncoder mapped for the id "null"
     * 原因:升级为Security5.0以上密码支持多中加密方式，恢复以前模式
     *
     * @return
     */
    @Bean
    public static NoOpPasswordEncoder passwordEncoder() {
        return (NoOpPasswordEncoder) NoOpPasswordEncoder.getInstance();
    }
}

3、测试controller接口

@Controller
public class IndexController {
    /**
     * 跳转到首页
     *
     * @return
     */
    @RequestMapping("/")
    public String index() {
        return "index";
    }
    @ResponseBody
    @RequestMapping("/addMember")
    public String addMember() {
        return "新增用户";
    }
    @ResponseBody
    @RequestMapping("/delMember")
    public String delMember() {
        return "删除用户";
    }
    @ResponseBody
    @RequestMapping("/updateMember")
    public String updateMember() {
        return "修改用户";
    }
    @ResponseBody
    @RequestMapping("/showMember")
    public String showMember() {
        return "查询用户";
    }
}

使用form表形式登录

在上面Basic认证模式的基础上修改SecurityConfig配置类，修改下面的方法

@Override
    protected void configure(HttpSecurity http) throws Exception {
        //配置httpBasic Http协议认证
        http.authorizeRequests().antMatchers("/**").fullyAuthenticated().and().formLogin();
    }

springSecurity默认提供登录页面，如下图所示：

注意：使用表单登录之后，登录成功之后默认跳转首页，也就是请求路径/，没有该请求路径的话会报错。

实现权限控制

上面的案例只是实现了登录认证，但是还没有实现权限控制。

在上面的基础上修改

1、修改SecurityConfig配置类

 @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        // 设置用户账号信息和权限
        auth.inMemoryAuthentication().withUser("kaico_admin").password("kaico")
                .authorities("addMember", "delMember", "updateMember", "showMember"
                );
        // 如果kaico_admin账户权限的情况 所有的接口都可以访问，如果kaico_add 只能访问addMember
        auth.inMemoryAuthentication().withUser("kaico_add").password("kaico")
                .authorities("addMember");
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //配置权限
        http.authorizeRequests().antMatchers("/addMember").hasAnyAuthority("addMember")
                .antMatchers("/addMember").hasAnyAuthority("addMember")
                .antMatchers("/delMember").hasAnyAuthority("delMember")
                .antMatchers("/updateMember").hasAnyAuthority("updateMember")
                .antMatchers("/showMember").hasAnyAuthority("showMember")
                .antMatchers("/**").fullyAuthenticated().and().formLogin();
    }

没有权限报403错误

修改403权限不足页面

1、增加配置类

@Configuration
public class WebServerAutoConfiguration {
    @Bean
    public ConfigurableServletWebServerFactory webServerFactory() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
        ErrorPage errorPage400 = new ErrorPage(HttpStatus.BAD_REQUEST, "/error/400");
        ErrorPage errorPage401 = new ErrorPage(HttpStatus.UNAUTHORIZED, "/error/401");
        ErrorPage errorPage403 = new ErrorPage(HttpStatus.FORBIDDEN, "/error/403");
        ErrorPage errorPage404 = new ErrorPage(HttpStatus.NOT_FOUND, "/error/404");
        ErrorPage errorPage415 = new ErrorPage(HttpStatus.UNSUPPORTED_MEDIA_TYPE, "/error/415");
        ErrorPage errorPage500 = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/error/500");
        factory.addErrorPages(errorPage400, errorPage401, errorPage403, errorPage404, errorPage415, errorPage500);
        return factory;
    }
}

2、增加对应的错误请求路径

@RestController
public class ErrorController {
    @RequestMapping("/error/403")
    public String error403(){
        return "您当前访问的接口权限不足";
    }
}

自定义登录页面

1、登录页面准备

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
    <title>Insert title here</title>
</head>
<body>
<h1>权限控制登陆系统</h1>
<form action="/login" method="post">
    <span>用户名称</span><input type="text" name="username"/> <br>
    <span>用户密码</span><input type="password" name="password"/> <br>
    <input type="submit" value="登陆">

</form>
<#if RequestParameters['error']??>
    用户名称或者密码错误
</#if>
</body>
</html>

2、修改SecurityConfig配置类

 @Override
    protected void configure(HttpSecurity http) throws Exception {
        //配置权限
        http.authorizeRequests().antMatchers("/addMember").hasAnyAuthority("addMember")
                .antMatchers("/addMember").hasAnyAuthority("addMember")
                .antMatchers("/delMember").hasAnyAuthority("delMember")
                .antMatchers("/updateMember").hasAnyAuthority("updateMember")
                .antMatchers("/showMember").hasAnyAuthority("showMember")
                .antMatchers("/login").permitAll() //放行登录请求页面
                .antMatchers("/**").fullyAuthenticated()
                .and().formLogin().loginPage("/login").and().csrf().disable();
    }

3、增加登录页面请求controller

@Controller
public class LoginController {
    @RequestMapping("/login")
    public String login(){
        return "login";
    }
}

结合数据库实现RBAC权限模型权限控制

环境准备

java代码

实体类

// 用户信息表
@Data
public class UserEntity implements UserDetails {
	private Integer id;
	private String username;
	private String realname;
	private String password;
	private Date createDate;
	private Date lastLoginTime;
	private boolean enabled;
	private boolean accountNonExpired;
	private boolean accountNonLocked;
	private boolean credentialsNonExpired;
	// 用户所有权限
	private List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
	public Collection<? extends GrantedAuthority> getAuthorities() {
		return authorities;
	}
}

// 角色信息表
@Data
public class RoleEntity {
	private Integer id;
	private String roleName;
	private String roleDesc;
}

@Data
public class PermissionEntity {
	private Integer id;
	// 权限名称
	private String permName;
	// 权限标识
	private String permTag;
	// 请求url
	private String url;
}

mapper类

@Mapper
public interface PermissionMapper {
    @Select(" select * from sys_permission ")
    List<PermissionEntity> findAllPermission();
}

@Mapper
public interface UserMapper {
    /**
     * 根据用户名称查询
     *
     * @param userName
     * @return
     */
    @Select(" select * from sys_user where username = #{userName}")
    UserEntity findByUsername(@Param("userName") String userName);
    /**
     * 查询用户的权限根据用户查询权限
     *
     * @param userName
     * @return
     */
    @Select(" select permission.* from sys_user user" + " inner join sys_user_role user_role"
            + " on user.id = user_role.user_id inner join "
            + "sys_role_permission role_permission on user_role.role_id = role_permission.role_id "

    List<PermissionEntity> findPermissionByUsername(@Param("userName") String userName);
}

实现springSecurity的接口UserDetailsService

@Component
@Slf4j
public class MemberUserDetailsService implements UserDetailsService {
    @Autowired
    private UserMapper userMapper;
    /**
     * loadUserByUserName
     *
     * @param username
     * @return
     * @throws UsernameNotFoundException
     */
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        // 1.根据该用户名称查询在数据库中是否存在
        UserEntity userEntity = userMapper.findByUsername(username);
        if (userEntity == null) {
            return null;
        }
        // 2.查询对应的用户权限
        List<PermissionEntity> listPermission = userMapper.findPermissionByUsername(username);
        List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
        listPermission.forEach(user -> {
            authorities.add(new SimpleGrantedAuthority(user.getPermTag()));
        });
        log.info(">>>authorities:{}<<<", authorities);
        // 3.将该权限添加到security
        userEntity.setAuthorities(authorities);
        return userEntity;
    }
}

密码加密工具类

public class MD5Util {
	private static final String SALT = "kaico";
	public static String encode(String password) {
		password = password + SALT;
		MessageDigest md5 = null;
		try {
			md5 = MessageDigest.getInstance("MD5");
		} catch (Exception e) {
			throw new RuntimeException(e);
		}
		char[] charArray = password.toCharArray();
		byte[] byteArray = new byte[charArray.length];
		for (int i = 0; i < charArray.length; i++)
			byteArray[i] = (byte) charArray[i];
		byte[] md5Bytes = md5.digest(byteArray);
		StringBuffer hexValue = new StringBuffer();
		for (int i = 0; i < md5Bytes.length; i++) {
			int val = ((int) md5Bytes[i]) & 0xff;
			if (val < 16) {
				hexValue.append("0");
			}
			hexValue.append(Integer.toHexString(val));
		}
		return hexValue.toString();
	}
}

SecurityConfig配置类

@Component
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private MemberUserDetailsService memberUserDetailsService;
    /**
     * 添加授权账户
     *
     * @param auth
     * @throws Exception
     */
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        // 设置用户账号信息和权限
        auth.userDetailsService(memberUserDetailsService).passwordEncoder(new PasswordEncoder() {
            @Override
            public String encode(CharSequence rawPassword) {
                //对密码做加密
                return MD5Util.encode((String) rawPassword);
            }
            /**
             *
             * @param charSequence 用户输入的密码
             * @param s 数据库字段中加密好的密码
             * @return
             */
            @Override
            public boolean matches(CharSequence charSequence, String s) {
                String rawPass = MD5Util.encode((String) charSequence);
                boolean result = rawPass.equals(s);
                return result;
            }
        });
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //配置权限
        http.authorizeRequests().antMatchers("/addMember").hasAnyAuthority("addMember")
                .antMatchers("/addMember").hasAnyAuthority("addMember")
                .antMatchers("/delMember").hasAnyAuthority("delMember")
                .antMatchers("/updateMember").hasAnyAuthority("updateMember")
                .antMatchers("/showMember").hasAnyAuthority("showMember")
                .antMatchers("/login").permitAll() //放行登录请求页面
                .antMatchers("/**").fullyAuthenticated()
                .and().formLogin().loginPage("/login").and().csrf().disable();
    }
}

整合完成，开始测试。

动态绑定数据库所有权限

在上面代码的基础上实现，上面是在代码中配置请求路径和权限标识的绑定，现在改成在数据库中动态配置。

SecurityConfig配置类

@Override
protected void configure(HttpSecurity http) throws Exception {
    //配置权限
    List<PermissionEntity> allPermission = permissionMapper.findAllPermission();
    ExpressionUrlAuthorizationConfigurer<HttpSecurity>.ExpressionInterceptUrlRegistry
            expressionInterceptUrlRegistry = http.authorizeRequests();
    allPermission.forEach((permission) -> {
        expressionInterceptUrlRegistry.antMatchers(permission.getUrl()).
                hasAnyAuthority(permission.getPermTag());
    });
    expressionInterceptUrlRegistry.antMatchers("/login").permitAll()
            .antMatchers("/**").fullyAuthenticated()
            .and().formLogin().loginPage("/login").and().csrf().disable();
}
