renderJson（）返回的数据格式

首先，有一个实体类，KvmCluster(不用管父类):

public class KvmCluster extends BaseReport{
	/**
	 * 时间
	 */
	public String timeStamp;
	
	/**
	 * 主机名
	 */
	public String nodeName;
	/**
	 * cpu核数
	 */
	public String avgNumberCpu;
	/**
	 * 内存大小
	 */
	public String avgTotalMemory;
	/**
	 * cpu最高使用率
	 */
	public String maxCpuUtilization;
	/**
	 * cpu平均使用率
	 */
	public String avgCpuUtilization;
	/**
	 * 内存最高使用率
	 */
	public String maxMemoryUtilization;
	/**
	 * 内存平均使用率
	 */
	public String avgMemoryUtilization;
}

renderJson(Object obj) 返回KvmCluster:

测试方法：

public static void testRenderJson(){
    
  		KvmCluster kc = new KvmCluster();
      	kc.avgCpuUtilization = i+"111";
      	kc.avgMemoryUtilization = i+ "222";
      	kc.avgNumberCpu = i+"333";
     
    	renderJSON(kc);
    }

测试结果：

{
	"avgNumberCpu": "333",
	"avgCpuUtilization": "111",
	"avgMemoryUtilization": "222"
}

没什么好说得。

renderJson() 返回List<KvmCluster>

测试代码：

public static void testRenderJson(){

    	List<KvmCluster> list1 = new ArrayList<>();
    	for(int i=0;i<3;i++){
    		KvmCluster kc = new KvmCluster();
        	kc.avgCpuUtilization = i+"111";
        	kc.avgMemoryUtilization = i+ "222";
        	kc.avgNumberCpu = i+"333";
        	list1.add(kc);
    	}
    	renderJSON(list1);
    }

测试结果：

[
    {
        "avgNumberCpu": "0333",
        "avgCpuUtilization": "0111",
        "avgMemoryUtilization": "0222"
    },
    {
        "avgNumberCpu": "1333",
        "avgCpuUtilization": "1111",
        "avgMemoryUtilization": "1222"
    },
    {
        "avgNumberCpu": "2333",
        "avgCpuUtilization": "2111",
        "avgMemoryUtilization": "2222"
    }
]

标准的JsonArray格式

renderJson() 返回Map<String,KvmCluster>

测试代码：

 public static void testRenderJson(){
    	
    	Map<String, Object> map = new HashMap<>();
    	
    	for(int i=0;i<3;i++){
    		KvmCluster kc = new KvmCluster();
        	kc.avgCpuUtilization = i+"111";
        	kc.avgMemoryUtilization = i+ "222";
        	kc.avgNumberCpu = i+"333";
        	map.put("key_"+i, kc);
    	}
    	renderJSON(map);
    }

测试结果：

{
    "key_2": {
        "avgNumberCpu": "2333",
        "avgCpuUtilization": "2111",
        "avgMemoryUtilization": "2222"
    },
    "key_1": {
        "avgNumberCpu": "1333",
        "avgCpuUtilization": "1111",
        "avgMemoryUtilization": "1222"
    },
    "key_0": {
        "avgNumberCpu": "0333",
        "avgCpuUtilization": "0111",
        "avgMemoryUtilization": "0222"
    }
}

renderJson() 返回Map<String,List<KvmCluster>>

测试代码：

 public static void testRenderJson(){
    	List<KvmCluster> list1 = new ArrayList<>();
    	List<KvmCluster> list2 = new ArrayList<>();
    	Map<String, List<KvmCluster>> mapList = new HashMap<>();
    	for(int i=0;i<3;i++){
    		KvmCluster kc = new KvmCluster();
        	kc.avgCpuUtilization = i+"111";
        	kc.avgMemoryUtilization = i+ "222";
        	kc.avgNumberCpu = i+"333";
        	list1.add(kc);
    	}
    	
    	for(int i=0;i<3;i++){
    		KvmCluster kc = new KvmCluster();
        	kc.avgCpuUtilization = i+"aaa";
        	kc.avgMemoryUtilization = i+ "bbb";
        	kc.avgNumberCpu = i+"ccc";
        	list2.add(kc);
    	}
    	
    	mapList.put("map1", list1);
    	mapList.put("map2", list2);
    	renderJSON(mapList);
    }

测试结果：

{
    "map2": [
        {
            "avgNumberCpu": "0ccc",
            "avgCpuUtilization": "0aaa",
            "avgMemoryUtilization": "0bbb"
        },
        {
            "avgNumberCpu": "1ccc",
            "avgCpuUtilization": "1aaa",
            "avgMemoryUtilization": "1bbb"
        },
        {
            "avgNumberCpu": "2ccc",
            "avgCpuUtilization": "2aaa",
            "avgMemoryUtilization": "2bbb"
        }
    ],
    "map1": [
        {
            "avgNumberCpu": "0333",
            "avgCpuUtilization": "0111",
            "avgMemoryUtilization": "0222"
        },
        {
            "avgNumberCpu": "1333",
            "avgCpuUtilization": "1111",
            "avgMemoryUtilization": "1222"
        },
        {
            "avgNumberCpu": "2333",
            "avgCpuUtilization": "2111",
            "avgMemoryUtilization": "2222"
        }
    ]
}

美化后的格式如下：
