title="Autowired依赖注入"></a>Autowired依赖注入</h3><p>基于@Autowired进行依赖注入的常见方式有如下三种：</p><ol><li><p>属性注入</p><p>优点:代码简洁、方便快速开发。</p><p>缺点:隐藏了类之间的依赖关系、可能会破坏类的封装性</p></li></ol><p><img src="/images/%E5%88%86%E5%B1%82%E8%A7%A3%E8%80%A6/%E5%B1%9E%E6%80%A7%E6%B3%A8%E5%85%A5.png" alt="属性注入"></p><ol start="2"><li><p>构造器注入</p><p>可以不写无参构造器。如果当前类中只存在一个构造函数，还可以省略@Autowired 注解</p><p>优点:能清晰地看到类的依赖关系、提高了代码的安全性。</p><p>缺点:代码繁琐、如果构造参数过多，可能会导致构造函数臃肿。</p><p>注意:如果只有一个构造函数，@Autowired注解可以省略。</p></li></ol><p><img src="/images/%E5%88%86%E5%B1%82%E8%A7%A3%E8%80%A6/%E6%9E%84%E9%80%A0%E5%99%A8%E6%B3%A8%E5%85%A5.png" alt="构造器注入"></p><ol start="3"><li><p>setter注入</p><p>优点:保持了类的封装性，依赖关系更清晰。<br>缺点:需要额外编写setter方法，增加了代码量。</p></li></ol><p><img src="/images/%E5%88%86%E5%B1%82%E8%A7%A3%E8%80%A6/setter%E6%B3%A8%E5%85%A5.png" alt="setter注入"></p><h3 id="Autowired-衍生"><a href="#Autowired-衍生" class="headerlink" title="@Autowired 衍生"></a>@Autowired 衍生</h3><p>@Autowired注解，默认是按照类型进行注入的<br>如果存在多个相同类型的bean，将会报错</p><p>解决方法：</p><ol><li>使用@Primary</li></ol><ul><li>这个注解用于指定当有多个相同类型的bean时，哪一个bean应该被优先考虑。当你通过类型来自动装配（autowire）一个bean时，如果有多个候选者，Spring容器会根据@Primary注解来决定使用哪一个。如果没有指定@Primary，Spring容器可能会抛出异常，因为它不知道应该选择哪一个。</li><li>例如，如果你有两个实现了相同接口的bean，你可以在一个bean上使用@Primary，这样当通过接口类型注入时，就会使用这个被标记为@Primary的bean。</li></ul><ol start="2"><li>搭配@Qualifier使用 @Autowired + @Qualifier</li></ol><ul><li>当你想要精确控制Spring容器应该注入哪一个bean时，可以使用@Qualifier注解。它通常与@Autowired注解一起使用，用于消除歧义，当你有多个相同类型的bean时，@Qualifier注解允许你指定注入哪一个具体的bean。</li><li>例如，如果你有两个名为”dataSource”的bean，你可以在注入时使用@Qualifier(“dataSource1”)来指定注入哪一个。</li></ul><ol start="3"><li>使用@Resource</li></ol><ul><li>@Resource注解是由Java EE提供的，它也可以用来注入bean，但与@Autowired不同，@Resource注解既可以根据类型注入，也可以根据名称注入。当没有指定name属性时，它会尝试根据字段名或setter方法的参数名来匹配bean。</li><li>@Resource注解有一个name属性，你可以指定一个bean的名称来注入特定的bean。如果没有指定name属性，它会根据字段名或setter方法的参数名来注入匹配的bean。</li><li>例如，如果你有一个名为”dataSource”的bean，你可以在需要注入的地方使用@Resource(name=”dataSource”)来指定注入这个bean。</li></ul><p>@Resource 与 @Autowired 的区别：</p><ol><li>@Autowired是Spring框架提供的注解，而@Resource是JavaEE规范提供的</li><li>@Autowired默认是按照类型注入，而Resource默认是按照名称注入</li></ol>]]></content>

<title>微信小程序开发iPhone底部因为横杠适配有问题</title>

<content type="html"><![CDATA[<p>在做一个商城小程序开发的时候遇到的一个问题，有些 iphone 手机最下边有一个横条，就像这样：</p><p><img src="/images/wechat-miniapp/wechatminiapp.png" alt="wechatminiapp"></p><p>当我们正常开发的时候就会变成：</p><p><img src="/images/wechat-miniapp/wechatminiapp2.png" alt="wechatminiapp2"></p><p>如果加一条 margin-bottom 适配就变得没问题了，但是如果在没有这条横杠的手机上就会变得很奇怪：</p><p><img src="/images/wechat-miniapp/wechatminiapp3.png" alt="wechatminiapp3"></p><p>解决办法：</p><p>增加一条 css 样式 <code>padding-bottom: env(safe-area-inset-bottom);</code></p><p>这用于设置元素的底部内边距。这里的<code>env()</code>函数是一个CSS环境变量函数，它允许你根据设备的特定环境特性来设置样式值。</p><p><code>safe-area-inset-bottom</code>是一个特定的环境变量，它返回的是设备屏幕底部安全区域的内边距值。安全区域是指在屏幕边缘（如刘海、圆角、传感器等）不会遮挡内容的区域。在一些设备上，尤其是带有刘海或圆角的手机屏幕上，内容可能会被这些屏幕特征遮挡，因此开发者需要避免在这些区域放置重要内容。</p><p>使用<code>env(safe-area-inset-bottom)</code>的好处是，它能够自动适应不同设备的屏幕形状和尺寸，确保内容不会被遮挡。这样，开发者就不需要硬编码一个固定的值，而是可以动态地根据设备的安全区域来调整布局。</p><p>简而言之，<code>padding-bottom: env(safe-area-inset-bottom);</code> 意味着元素的底部内边距将等于设备底部安全区域的内边距，从而确保内容不会被屏幕底部的任何遮挡物（如刘海）遮挡。</p>]]></content>
