工具类 Json

jsonConfig.setExcludes用法

/**
 * 联系人实体
 */
public class LinkMan {
	private Integer id; // 编号
	private Customer customer; // 所属客户
	private String linkName; // 姓名
	private String sex; // 性别
	private String zhiwei; // 职位
	private String officePhone; // 办公电话
	private String phone; // 手机
}

/**
 * 客户实体
 */
public class Customer {
	private Integer id; // 编号
	private String khno; // 客户编号 动态生成
	private String name; // 客户名称
	private String area; // 客户地区
	private String cusManager; // 客户经理
	private String address; // 客户地址
	其他属性略
}

目标

LinkMan对象中有Customer的属性对象，如果想不要这个可以使用jsonConfig工具中的excludes剔除
jsonConfig.setExcludes(new String[]{“customer”});

		HashMap<String,Object> map = new HashMap<>();
		map.put("cusId", cusId);
		List<LinkMan> linkManList = linkManService.getLinkManList(map);
		
		JSONObject result=new JSONObject();
		JsonConfig jsonConfig=new JsonConfig();		
		jsonConfig.setExcludes(new String[]{"customer"});
		
		//JSONArray jsonArray=JSONArray.fromObject(linkManList);//不剔除
		JSONArray jsonArray=JSONArray.fromObject(linkManList,jsonConfig);//剔除customer属性	

结果

不剔除customer属性的结果如下

[{"customer":{"address":"","area":"","cusManager":"","dsdjh":"","fax":"","fr":"","gsdjh":"","id":21,"khno":"KH20150526073027","khyh":"","khzh":"","level":"大客户","myd":"","name":"百度","nyye":"","phone":"","postCode":"","state":0,"webSite":"","xyd":"","yyzzzch":"","zczj":""},"id":8,"linkName":"22","officePhone":"1","phone":"1","sex":"男","zhiwei":"21"},{"customer":{"address":"","area":"","cusManager":"","dsdjh":"","fax":"","fr":"","gsdjh":"","id":21,"khno":"KH20150526073027","khyh":"","khzh":"","level":"大客户","myd":"","name":"百度","nyye":"","phone":"","postCode":"","state":0,"webSite":"","xyd":"","yyzzzch":"","zczj":""},"id":9,"linkName":"2244","officePhone":"24","phone":"4","sex":"男","zhiwei":"422"}]

剔除customer属性后的结果如下

[{"id":8,"linkName":"22","officePhone":"1","phone":"1","sex":"男","zhiwei":"21"},{"id":9,"linkName":"2244","officePhone":"24","phone":"4","sex":"男","zhiwei":"422"}]

注：用的是net下的包
import net.sf.json.JSONArray;
import net.sf.json.JSONObject;
import net.sf.json.JsonConfig;
