Javabean转换成json字符并首字母大写代码实例

import com.fasterxml.jackson.annotation.JsonProperty;
public class DiagResponeBean {
  @JsonProperty( "SN")
  private String sn;//设备sn
  @JsonProperty( "result")
  private String result;//响应诊断结果
  @JsonProperty( "Region")
  private String region;//管理域
  @JsonProperty( "Status")
  private String status;//设备状态
  //setter/getter
}
//controller 接口部分代码
 com.fasterxml.jackson.databind.ObjectMapper ob =new com.fasterxml.jackson.databind.ObjectMapper();
    //json转bean时忽略大小写
    ob.configure(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES, true);
      if(StringUtil.isEmpty(json)){
        diagResponeBean.setSn("");
        diagResponeBean.setResult("入参不能为空");
        diagResponeBean.setRegion("");
        diagResponeBean.setStatus("");
        ob.writeValue(response.getOutputStream(), diagResponeBean);
        return;
      }
