spring boot:用spring security加强druid的安全(druid 1.1.22 / spring boot 2.3.3)

一，druid的安全保障有哪些环节要注意?

1，druid ui的访问要有ip地址限制

2,用户必须要有相应的权限才能访问druid

3,关闭重置功能

说明：stat-view-servlet.url-pattern的配置应用时会报错，

        如果bug修改了，使用这个功能会更安全

四，java代码说明：

1,SecurityConfig.java

@Configuration
@EnableWebSecurity
 public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //针对druid的ui,关闭csrf,否则会无法登录
        http.csrf().ignoringAntMatchers("/druid/**");

        //login和logout
        http.formLogin()
                .defaultSuccessUrl("/goods/session")
                .failureUrl("/login-error.html")
                .permitAll()
                .and()
                .logout();

        //指定访问druid的role
        String druidRule = "hasAnyRole('ADMIN','DEV')";
        //匹配的页面，符合限制才可访问
        http.authorizeRequests()
                .antMatchers("/druid/**").access(druidRule)
                .antMatchers("/goods/**").hasAnyRole("ADMIN","DEV","USER");

        //剩下的页面，允许访问
        http.authorizeRequests().anyRequest().permitAll();
    }

    @Autowired
    public  void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        //添加两个账号用来做测试
        auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
                .withUser("lhdadmin")
                .password(new BCryptPasswordEncoder().encode("123456"))
                .roles("ADMIN","USER")
                .and()
                .withUser("lhduser")
                .password(new BCryptPasswordEncoder().encode("123456"))
                .roles("USER");
    }
 }

说明：

      http.csrf().ignoringAntMatchers("/druid/**");

      针对druid关闭csrf,否则会导致无法登录,其他页面不受影响

     antMatchers("/druid/**").access(druidRule)
     指定了访问druid监控view的规则

2,GoodsController.java

@Controller
@RequestMapping("/goods")
public class GoodsController {

    @Resource
    private GoodsMapper goodsMapper;

    //商品详情 参数:商品id
    @GetMapping("/goodsinfo")
    @ResponseBody
    public Goods goodsInfo(@RequestParam(value="goodsid",required = true,defaultValue = "0") Long goodsId) {
        Goods goods = goodsMapper.selectOneGoods(goodsId);
        return goods;
    }

    //打印当前登录用户的session
    @GetMapping("/session")
    @ResponseBody
    public String session() {
        HttpSession session = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest().getSession();
        Enumeration e   =   session.getAttributeNames();
        String s = "";
        while( e.hasMoreElements())   {
            String sessionName=(String)e.nextElement();
            s += "name="+sessionName+";<br/>";
            s += "value="+session.getAttribute(sessionName)+";";
        }
        return s;
    }
}

3,GoodsMapper.java,GoodsMapper.xml,Goods.java等用来演示通过druid访问数据源，不再贴出，

   大家可访问github.com查看

五，效果测试

1,使用无权限的用户登录后访问

用lhduser登录

session信息中可以看到授权的角色是:ROLE_USER 

访问druid:

 因为没有权限，我们看到了报错信息

2,使用有权限的用户登录后访问

 用lhdadmin登录,查看session：

 查看druid，先用配置的账号root登录

 可以正常访问:

3,从未授权的ip访问:注意替换成自己应用所在的ip

http://192.168.3.182:8080/druid

用有权限的账号lhdadmin登录，

返回:

 可见既使有权限访问，但如果ip未加入白名单也会报错

六，查看spring boot的版本
