我们在之前的文章中已经在SpringMVC基础框架的基础上应用了BootStrap的后台框架，在此基础上记录?地址联动输入用法。

应用bootstrap模板

基础项目源码下载地址为:

SpringMVC+Shiro+MongoDB+BootStrap基础框架

我们在基础项目中已经做好了首页index的访问。
现在就在index.jsp页面和index的路由Controller上做修改，实现 地址联动输入用法。

引用cxselect资源

cxselect是一个jQuery的插件，封装了联动处理的功能，我们这里的城市联动选择也由这个插件来提供，所以需要先引用。

相关网站:

https://www.npmjs.com/package/cxselect

https://github.com/ciaoca/cxSelect

示例:

或者在我的资源中直接下载:

下载到的资源如图:

放入项目的res目录下的assets目录的js文件夹中如图:

引用时使用代码:

<script src="/res/assets/js/jquery.cxselect.js"></script>

初始化cxselect

jsp中的占位符

 <div class="col-sm-8 input-group" id="districtInfo">
                      <select class="province form-control" style="width:90px" id="province" name="province"></select>
                      <select class="city form-control" style="width:90px" id="city" name="city"></select>
                      <select class="area form-control" style="width:90px" id="area" name="area"></select>
                    </div>

使用代码初始化

<script type="text/javascript">  
$.cxSelect.defaults.url = '/res/assets/js/cityData.min.json';
$.cxSelect.defaults.emptyStyle = 'none';
$('#districtInfo').cxSelect({
  url: '/res/assets/js/cityData.min.json',// 如果服务器不支持 .json 类型文件，请将文件改为 .js 文件
  selects: ['province','city','area'],// 数组，请注意顺序
  emptyStyle: 'none'
});
</script>

后端接收代码IndexController.java

package com.test.web.controller;

import java.io.IOException;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

/**
 * IndexController
 * 
 * 
 */
@Controller
public class IndexController {

	
	@Value("${version.name:}")
	private String version;
	
	@RequestMapping("/")
	public String index(Model model) throws IOException {
          model.addAttribute("version",version);
		return "/index";
	}
	
    @RequestMapping(value="/add",method=RequestMethod.POST)    
    public String login(@RequestParam String province,@RequestParam String city,@RequestParam(defaultValue="") String area){    
        System.out.println(province+city+area);
            return "/index";    
    }  

}

需要注意的是 直辖市 北京等 只有到 区 ?也就是没有 area字段。界面上操作时也只会显示到第二级。

效果如图
