這個構(gòu)造函數(shù)可以指定大小端！

再給后臺上傳圖片路徑，可是獲取的圖片路徑一直是64位編碼的，后臺只要正常的圖片路徑

首先，這不是 base64編碼的路徑，這就是base64編碼之后的圖片實(shí)體，準(zhǔn)確的說是 base64編碼的DATA URI你通過H5的 File API拿到這一大坨DATA URI是沒問題的；

然后，"后臺只要正常的圖片路徑" 這是扯犢子，前端上傳個本地的 URL 路徑(比如c://assets/pic1.jpg)給后臺是沒有意義的，后臺需要的是你上面的那一大坨base64 URI，他需要自己decode

涉及到j(luò)ava的參數(shù)傳遞問題。具體解釋可以參考：

https://www.zhihu.com/questio...

上面說的很詳細(xì)。關(guān)于這塊，通常給這種非基本類型增加一個包裝類處理。

public class Test {

    private static class Wrapper{
        int[] res;

        Wrapper(int[] res){
            this.res = res;
        }
    }

    public static void main(String[] args) {
        Test t = new Test();

        int[] res = new int[1];
        Wrapper wrapper = new Wrapper(res);
        t.dfs(5, wrapper);
        System.out.println(Arrays.toString(wrapper.res));
    }

    public void dfs(int k, Wrapper obj) {
        if (k == 5) {
            obj.res = new int[]{1, 2, 3, 4, 5};
            return;
        }
        dfs(k + 1, obj);
    }
}

 var filename = "./src/pages/scene/register/register.ejs";
    //ext = /[^.]+$/.exec(filename);
    ext = filename.split('.').pop();
    console.log(ext);

問題一：
從文件中讀取數(shù)據(jù)的代碼可以封裝為一個單獨(dú)的方法，例如：

public static String readFileAsString(String filePath) throws IOException {
    return readFileAsString(new File(filePath));
}

public static String readFileAsString(File file) throws IOException {
    try (BufferedReader reader = new BufferedReader(new FileReader(file))) {
        StringBuilder content = new StringBuilder();

        for (String line; (line = reader.readLine()) != null;) {
            content.append(line);
        }

        return content.toString();
    }
}

如果使用 Java8，readFileAsString 方法會更簡單：

public static String readFileAsString(File file) throws IOException {
    return Files.lines(file.toPath()).collect(Collectors.joining(""));
}

這樣的話，你就不需要每次讀取某個文件的時候，都寫一堆邏輯同樣的代碼，而是直接調(diào)用 readFileAsString 方法就行。

問題二：
Java 遍歷某個目錄的 API 很多，如果只是非遞歸遍歷，即只列出當(dāng)前目錄的文件，可以使用：

1. File 類的 listFiles 方法
2. Files 類的 list 方法，返回 Stream<Path>，從而可以使用 Lambda 表達(dá)式。

promise.all已經(jīng)是最簡單的方法了，其他的都要手工處理全部完成這個邏輯

標(biāo)準(zhǔn)約定std::thread構(gòu)造時向函數(shù)對象傳遞實(shí)際參數(shù)的拷貝（支持移動語義），而不是轉(zhuǎn)發(fā)實(shí)際參數(shù)（你可以通過打印實(shí)際參數(shù)和形式參數(shù)的地址來檢測這一行為）。即fun的形式參數(shù)是被a的拷貝初始化的，所以形式參數(shù)a并不是main函數(shù)內(nèi)a的引用，在fun內(nèi)賦值自然不會改變main函數(shù)內(nèi)a的值。

如果你希望“以引用的方式傳參”，常用解決方案之一是使用std::ref，即std::thread(fun, std::ref(a));。

@Controller //使用該注解標(biāo)志它是一個控制器
@RequestMapping(value = "/person")
public class PersonController {

@RequestMapping(value = "/register", method = RequestMethod.POST) 
public Object register(@RequestBody Person person) {
    //todo
    return person;
}

｝

通過你給出的日志，我只能看出springboot啟動時掃描不到dao層接口
我建議你在啟動類里面加上mapper掃描注解，如@MapperScan("com.qtay.gls.dao")

onchange="this.parentNode.nextSibling.value = this.value"
不明白為什么要這個

應(yīng)該是你js代碼有問題 查看下js第二次發(fā)出的請求的url參數(shù) 還有中文url傳參數(shù) 最好使用encodeURI

建議你在java里轉(zhuǎn)換,不要把壓力交給數(shù)據(jù)庫.

箭頭函數(shù)沒有自己的this。它的this并不是像你想的那樣指向當(dāng)前子類或base對象，而是在定義的時候的當(dāng)前對象。如果你是在全局作用域下創(chuàng)建的base類，那就是undefined。

idea的話，最好是結(jié)合maven一起使用，基于maven構(gòu)建項(xiàng)目，當(dāng)你在項(xiàng)目里使用ssh框架時，idea會自動的檢測到并且提示里添加相關(guān)的框架支持。。。

        return new RedisCacheManager(
            RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory),
            this.getRedisCacheConfigurationWithTtl(600), // 默認(rèn)策略，未配置的 key 會使用這個
            this.getRedisCacheConfigurationMap() // 指定 key 策略
        );
    }

    private Map<String, RedisCacheConfiguration> getRedisCacheConfigurationMap() {
        Map<String, RedisCacheConfiguration> redisCacheConfigurationMap = new HashMap<>();
        redisCacheConfigurationMap.put("UserInfoList", this.getRedisCacheConfigurationWithTtl(3000));
        redisCacheConfigurationMap.put("UserInfoListAnother", this.getRedisCacheConfigurationWithTtl(18000));

        return redisCacheConfigurationMap;
    }

    private RedisCacheConfiguration getRedisCacheConfigurationWithTtl(Integer seconds) {
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);

        RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig();
        redisCacheConfiguration = redisCacheConfiguration.serializeValuesWith(
            RedisSerializationContext
                .SerializationPair
                .fromSerializer(jackson2JsonRedisSerializer)
        ).entryTtl(Duration.ofSeconds(seconds));

        return redisCacheConfiguration;
    }
}

要指定 key 的過期時間，只要在getRedisCacheConfigurationMap方法中添加就可以。
然后只需要 @Cacheable 就可以把數(shù)據(jù)存入 redis

    @Cacheable(value = "UserInfoList", keyGenerator = "simpleKeyGenerator") // 3000秒
    @Cacheable(value = "UserInfoListAnother", keyGenerator = "simpleKeyGenerator") // 18000秒
    @Cacheable(value = "DefaultKeyTest", keyGenerator = "simpleKeyGenerator") // 600秒，未指定的key，使用默認(rèn)策略
    

前后端分離的話，前端獲取返回的數(shù)據(jù)，根據(jù)業(yè)務(wù)（也就是你的類型）進(jìn)行跳轉(zhuǎn)
未分離的情況如果用的是balde模板，改下return view('你想跳轉(zhuǎn)的頁面的名稱')即可吧

把市和區(qū)按照children嵌套

arr.map(item => {
  console.log(item);
  return {
    value:item.name,
    label:item.name,
    children: item.city.map(city => {
      return {
        name:city.name,
        label:item.name,
        children:city.area.map(area => {
          return {
          name: area,
          label:area
        }
      })
      }
    })
  }
})

已解決。

@Configuration
@EnableResourceServer
public class ResourceServerConfiguration
        extends ResourceServerConfigurerAdapter {
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
            .requestMatchers()
                .antMatchers("/api/**")
                .and()
                .authorizeRequests()
                .antMatchers("/api/**")
                .authenticated();
    }
}

解決了，原因是因?yàn)闆]在外層加<ul>....
