感谢tggagne的评论，我意识到人们仍然看到这个答案。这里的代码已经有 2.5 年的历史了。如果您想查看它 - 检查编辑历史记录。
与此同时，发生了很多变化，创建了更多混搭示例。其中最重要的是 Cory Cowgill 的“SF Bus Radar”（github、youtube）应用程序（我认为是在 Dreamforce'11 上创建的）。
尽管如此 - 这是我更新的示例，其中包含服务器端地理编码、地理定位类型的新字段和 JSON 解析器的使用。
它尝试将地理编码结果缓存在联系人记录中。请记住，它可能不是“生产就绪”（没有 Google Business API 密钥 = 因为我们所有的请求都来自同一个 Salesforce IP 服务器池，所以可能会出现错误消息）。这就是为什么我也离开了客户端地理编码。
在签出之前，您需要在环境中进行 2 处更改：
- 添加指向https://maps.googleapis.com的“远程站点设置”以启用来自 Apex 的标注
在设置 -> 自定义 -> 联系人 -> 字段中添加字段“位置”。类型应为“地理位置”。我选择了显示为小数和 6 位小数的精度。

从 Spring '15 开始，我们也可以apex:map在没有额外的 Google API 的情况下使用。在 Lightning 中查看时也有效——没有具体的个人经验，但这就是我读到的。
文档中的示例：
<apex:map width="600px" height="400px" mapType="roadmap" center="{!Account.BillingStreet}, {!Account.BillingCity}, {!Account.BillingState}">
<!-- Add a CUSTOM map marker for the account itself -->
<apex:mapMarker title="{! Account.Name }" position="{!Account.BillingStreet}, {!Account.BillingCity}, {!Account.BillingState}" icon="{! URLFOR($Resource.MapMarkers, 'moderntower.png') }"/>
<!-- Add STANDARD markers for the account's contacts -->
<apex:repeat value="{! Account.Contacts }" var="ct">
<apex:mapMarker title="{! ct.Name }" position="{! ct.MailingStreet }, {! ct.MailingCity }, {! ct.MailingState }"></apex:mapMarker>
</apex:repeat>
</apex:map>
在示例中，{! Account.Contacts }是一个正在迭代的联系人列表。每次迭代，它都会创建apex:mapMarker's 以映射列表中的所有联系人。尽管 OP 很旧，但“搜索结果”基本上可以替换{Account.Contacts}示例中被迭代的列表。
文档： 从该示例中提取的文档。
（我知道这是旧的，但是从更新中被带到了顶部，所以认为不使用 API 的更新是可以的。）
