如何使用64位编码凭据设置基本授权？我尝试了两个命令,但没有用,请建议.

curl -i -H 'Accept:application/json' Authorization:Basic <username:password> http://example.com
curl -i -H 'Accept:application/json' Authorization:Basic.base64_encode(username:password) http://example.com  

我有以下代码使用Java 7功能,如java.nio.file.Files和java.nio.file.Paths

import java.io.File;
import java.io.IOException;
import java.io.StringWriter;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.ArrayList;
import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.databind.node.ObjectNode;


public class JacksonObjectMapper {

    public static void main(String[] args) throws IOException {

        byte[] jsonData = Files.readAllBytes(Paths.get("employee.txt"));
        ObjectMapper objectMapper = new ObjectMapper();
        Employee emp = objectMapper.readValue(jsonData, Employee.class);
        System.out.println("Employee Object\n"+emp);
        Employee emp1 = createEmployee();
        objectMapper.configure(SerializationFeature.INDENT_OUTPUT, true);
        StringWriter stringEmp = new StringWriter();
        objectMapper.writeValue(stringEmp, emp1);
        System.out.println("Employee JSON is\n"+stringEmp);
    }
}

现在我必须在Java 6上运行相同的代码,除了使用FileReader之外,还有哪些最好的替代方案？

我在我的Hibernate中使用了以下查询,即createSQLQuery

SELECT to_char(dd, 'Mon YYYY') FROM generate_series('2013-01-01'::date, date_trunc('month', now()), '1 month') as dd 

在PostgreSQL中运行时生成输出

1. "2013年1月""2013年2月".."2014年2月"

但是,当通过如下的createSQLQuery使用它时,它会抛出" org.hibernate.QueryException:并未设置所有已命名的参数:[:date] "

请注意,日期已被用作' 2013-01-01':: date

try{
            session = HibernateSessionFactory.getSession(); 
            tx = session.beginTransaction();

            Query query = session.createSQLQuery("SELECT to_char(dd, 'Mon YYYY') FROM generate_series('2013-01-01'::date, date_trunc('month', now()), '1 month') as dd");
            monthList = new ArrayList<String>();            
            monthList = query.list();
            tx.commit();
        }

请建议

朋友我想将后续URL的默认蓝色更改为RED,我尝试使用style ="color:red但它没有帮助.请建议一个更好的方法.

<div class="row-fluid">
    <div class="span12" style="color:red"><a href="/event/alert/recipient/list/${alertStatusForm.forAlert.id}" class="underline">${fn:length(alertStatusForm.totalNotSentRecipient)}</a>
    </div>
</div>

我有一张表有列

recordID,recordName,titleFeild,titleIDMap,titleId,titleStartDate,titleEndDate,languageId

现在我将上面列中的数据转换为JSON对象数据,如下所示

{
  "recordId" :10,
  "recordName" : "RECORDS",
  "records" : [ {
    "titleField" : 1,
    "titleIDMap" : null,
    "titleId" : 500,
    "titleStartDate" : "2013-12-22T00:00:00.000+0000",
    "titleEndDate" : "2013-12-03T00:00:00.000+0000",
    "languageId" : 20
  }]
}

请注意,记录是一个列数组(titleFeild,titleIDMap,titleId,titleStartDate,titleEndDate,languageId)

到目前为止我开发的代码是

    List<Object[]> objList = dao.getStatus();
    Integer result = null;
     JSONObject jsonData = new JSONObject();
     JSONArray jsonDataArray = new JSONArray();
    if(objList!=null && objList.size()>10000)
        {
            for (Object[] nameObj : objList) {

                jsonData.put("", nameObj.get(arg0) );


            }
        }

如何从列数据构造JSON对象？

我有以下查询

select substring(listDate from '............$') as v_end_date,
substring(listDate from '^...............') as v_start_date

现在 listDate 值可以是这样的

select substring('06 Jan 2014 to 12 Jan 2014,
 13 Jan 2014 to 19 Jan 2014,
 20 Jan 2014 to 26 Jan 2014
' from '............$') as v_end_date,
substring('06 Jan 2014 to 12 Jan 2014,
 13 Jan 2014 to 19 Jan 2014,
 20 Jan 2014 to 26 Jan 2014
' from '^............') as v_start_date

以上查询结果为

V_END_DATE  V_START_DATE
26 Jan 2014 06 Jan 2014

现在我需要有v_end_date和 …

我使用以下代码以yyyy-MM-dd格式计算当前年份值但是下面的代码将paramStartDate值指定为0001-01-01,这是不正确的应该是'2014-01-01'

else if(scopeSelected != null && scopeSelected.equalsIgnoreCase("Year To Date")){

                    Calendar calendarStart = Calendar.getInstance();
                    calendarStart.set(Calendar.YEAR,calendarStart.YEAR);
                    calendarStart.set(Calendar.MONTH,0);
                    calendarStart.set(Calendar.DAY_OF_MONTH,1);
                    Date startDate=calendarStart.getTime();
                    DateFormat dateFormat1 = new SimpleDateFormat("yyyy-MM-dd");
                    paramStartDate = dateFormat1.format(startDate);
                    setParamStartDate(paramStartDate);
                }
