Spring Security认证相关URL实现可配置

application.yml

server:
  port: 80
spring:
  thymeleaf:
    cache: false #关闭Thymeleaf缓存
mengxuegu:
  security:
    authentication:
      loginPage: /login/page  #响应认证（登录）页面URL
      loginProcessingUrl: /login/form #登录表单提交处理URL
      usernameParameter: name # 登录表单用户名的属性名
      passwordParameter: pwd # 登录表单密码的属性名
      staticPaths: # 静态资源 "/dist/**", "/modules/**", "/plugins/**"
        - /dist/**
        - /modules/**
        - /plugins/**

创建AuthenticationProperties类

package com.mengxuegu.security.properties;

import lombok.Data;

@Data
public class AuthenticationProperties {
    // application.yml 没配置取默认值
    private String loginPage = "/login/page";
    private String loginProcessingUrl = "/login/form";
    private String usernameParameter = "name";
    private String passwordParameter = "pwd";
    private String[] staticPaths = {"/dist/**", "/modules/**", "/plugins/**"};
    
}

创建SecurityProperties类

package com.mengxuegu.security.properties;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component // 不要少了
@ConfigurationProperties( prefix = "mengxuegu.security")
public class SecurityProperties {
    // 将application.yml 中的 mengxuegu.security.authentication 下面的值绑定到此对象中
    private AuthenticationProperties authentication;

    public AuthenticationProperties getAuthentication() {
        return authentication;
    }

    public void setAuthentication(AuthenticationProperties authentication) {
        this.authentication = authentication;
    }
}

在SpringSecurityConfig中应用

package com.mengxuegu.security.config;

import com.mengxuegu.security.properties.SecurityProperties;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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.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;
import org.springframework.security.crypto.password.PasswordEncoder;


/**
 * alt+/ 导包

 * @Auther: 梦学谷 www.mengxuegu.com
 */
@EnableWebSecurity // 开启springsecurity过滤链 filter
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {


    Logger logger = LoggerFactory.getLogger(getClass());

    @Autowired
    private SecurityProperties securityProperties;

    @Bean
    public PasswordEncoder passwordEncoder(){
        // 明文+随机盐值-》加密存储
        return new BCryptPasswordEncoder();
    }

    /**
     * 认证管理器：
     * 1. 认证信息（用户名，密码）
     * @param auth
     * @throws Exception
     */
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        String password = passwordEncoder().encode("123456");
        logger.info("加密之后存储的密码："+password);
        auth.inMemoryAuthentication().withUser("root").password(password).authorities("ADMIN");
    }

    /**
     * 资源权限配置：
     * 1. 被拦截的资源
     * @param http
     * @throws Exception
     */
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        System.out.println("用户认证");
//       http.httpBasic() // 采用 httpBasic认证方式
        http.formLogin() // 表单登录方式
                .loginPage(securityProperties.getAuthentication().getLoginPage())   //配置登录页面
                .loginProcessingUrl(securityProperties.getAuthentication().getLoginProcessingUrl())  //登录表单提交处理url，默认是/login
                .usernameParameter(securityProperties.getAuthentication().getUsernameParameter())
                .passwordParameter(securityProperties.getAuthentication().getPasswordParameter())
            .and()
            .authorizeRequests() // 认证请求
            .antMatchers(securityProperties.getAuthentication().getLoginPage()).permitAll()
            .anyRequest().authenticated() //所有访问该应用的http请求都要通过身份认证才可以访问
        ; // 注意不要少了分号
    }

    /**
     * 一般针对静态资源放行
     * @param web
     */
    @Override
    public void configure(WebSecurity web) {
        web.ignoring().antMatchers(securityProperties.getAuthentication().getStaticPaths());
    }
}
