Java 解析Json数据

Json格式字符串
{
success:0,
errorMsg:"错误消息",
data:{
total:"总记录数",
rows:[
{
id:"任务ID",
workName:"任务名称",
assigneeName:"经办人姓名",
name:"流程步骤名称",
processInstanceInitiatorName:"发起人",
processInstanceStartTime:"发起时间",
createTime:"到达时间",
dueDate:"截止时间"
},
{
id:"ID",
workName:"名称",
assigneeName:"经办人",
name:"流程",
processInstanceInitiatorName:"发起人",
processInstanceStartTime:"发起",
createTime:"到达",
dueDate:"截止"
}
]
}
}

解析出数据:

json-lib-2.4-jdk15.jar  这个包还另需一下几个包。

jakarta commons-lang 2.5
jakarta commons-beanutils 1.8.0
jakarta commons-collections 3.2.1
jakarta commons-logging 1.1.1
ezmorph 1.0.6

        JSONObject ob = new JSONObject(str);

        Object success = ob.get("success");

        Object errorMsg = ob.get("errorMsg");

        System.out.println(success);

        System.out.println(errorMsg);

        JSONObject data = ob.getJSONObject("data");

        Object total = data.get("total");

        System.out.println(total);

        JSONArray array = data.getJSONArray("rows");

        JSONObject rows = null;

        for (int i = 0; i < array.length(); i++) {

            rows = array.getJSONObject(i);

            Object id = rows.get("id");

            System.out.println(id);

            Object workName = rows.get("workName");

            System.out.println(workName);

            Object assigneeName = rows.get("assigneeName");

            System.out.println(assigneeName);

            Object name = rows.get("name");

            System.out.println(name);

            Object processInstanceInitiatorName = rows.get("processInstanceInitiatorName");

            System.out.println(processInstanceInitiatorName);

            Object processInstanceStartTime = rows.get("processInstanceStartTime");

            System.out.println(processInstanceStartTime);

            Object createTime = rows.get("createTime");

            System.out.println(createTime);

            Object dueDate = rows.get("dueDate");

            System.out.println(dueDate);

        }
