java字符串类型和时间类型的转换

类型转换

 1 //Date类型转换成String类型
 2  public static String toJson(Object obj){
 3        String reuqest=null;
 4         //对象映射
 5          ObjectMapper mapper=new ObjectMapper();
 6           //设置时间格式
 7          SimpleDateFormat dateFormat=new SimpleDateFormat("yyyy年MM月dd日");
 8           mapper.setDateFormat(dateFormat);
 9              try {
10                  reuqest=mapper.writeValueAsString(obj);
11              } catch (JsonProcessingException e) {
12                  // TODO Auto-generated catch block
13                 e.printStackTrace();
14             }
15         return reuqest;
16      }
