一，druid的安全保障有哪些環節要注意?

1，druid ui的訪問要有ip地址限制

2,使用者必須要有相應的許可權才能訪問druid

3,關閉重置功能

說明：stat-view-servlet.url-pattern的配置應用時會報錯，

如果bug修改了，使用這個功能會更安全

2,application.properties

#   配置監控統計攔截的filters，去掉後監控介面sql無法統計，'wall'用於防火牆
spring.datasource.druid.filters = stat,wall,log4j2
spring.datasource.druid.maxPoolPreparedStatementPerConnectionSize = 20
spring.datasource.druid.useGlobalDataSourceStat = true

說明：以下是安全配置的重點

#使重置功能不起作用
spring.datasource.druid.stat-view-servlet.reset-enable=false
#配置訪問監控view的使用者名稱密碼
spring.datasource.druid.stat-view-servlet.login-username=root
spring.datasource.druid.stat-view-servlet.login-password=root
# IP白名單 (沒有配置或者為空，則允許所有訪問)
spring.datasource.druid.stat-view-servlet.allow = 127.0.0.1,192.168.1.1
# IP黑名單 (存在共同時，deny優先於allow)
spring.datasource.druid.stat-view-servlet.deny = 192.168.10.1

四，java程式碼說明：

1,SecurityConfig.java

@Configuration
@EnableWebSecurity
 public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //針對druid的ui,關閉csrf,否則會無法登入
        http.csrf().ignoringAntMatchers("/druid/**");

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

        //指定訪問druid的role
        String druidRule = "hasAnyRole('ADMIN','DEV')";
        //匹配的頁面，符合限制才可訪問
        http.authorizeRequests()
                .antMatchers("/druid/**").access(druidRule)
                .antMatchers("/goods/**").hasAnyRole("ADMIN","DEV","USER");

        //剩下的頁面，允許訪問
        http.authorizeRequests().anyRequest().permitAll();
    }

    @Autowired
    public  void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        //新增兩個賬號用來做測試
        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");
    }
 }

說明：

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

針對druid關閉csrf,否則會導致無法登入,其他頁面不受影響

antMatchers("/druid/**").access(druidRule)
指定了訪問druid監控view的規則

2,GoodsController.java

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

    @Resource
    private GoodsMapper goodsMapper;

    //商品詳情 引數: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;
    }

    //列印當前登入使用者的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等用來演示通過druid訪問資料來源，不再貼出，

大家可訪問github.com檢視

五，效果測試

1,使用無許可權的使用者登入後訪問

用lhduser登入

session資訊中可以看到授權的角色是:ROLE_USER

訪問druid:

因為沒有許可權，我們看到了報錯資訊

2,使用有許可權的使用者登入後訪問

用lhdadmin登入,檢視session：

檢視druid，先用配置的賬號root登入

可以正常訪問:

3,從未授權的ip訪問:注意替換成自己應用所在的ip

http://192.168.3.182:8080/druid

用有許可權的賬號lhdadmin登入，

返回:

可見既使有許可權訪問，但如果ip未加入白名單也會報錯

六，檢視spring boot的版本
