Java code objects are as follows:

Package com.evideostb.billsystem.module.model;import org.codehaus.jackson.map.annotate.jsonserialize ;import com.fasterxml.jackson.annotation.jsonignore;import  com.fasterxml.jackson.annotation.jsonproperty;/** *  response protocol Header  *  @author  zhangchuanzhao  * 2015-9-18 pm 3:12:58 */@JsonSerialize (include=jsonserialize.inclusion.non_null) public  class responseprotocol {//Error number:0  success &NBSP, other indicates failure protected string errorcode;// Tip Error Message protected string errormessage;//exception error message protected string exceptmessage;/** *   Get error number:0  success &NBSP, other represents failure  *  @return  */public string geterrorcode ()  { Return errorcode;} /** *  Set error number:0  success &NBSP, other indicates failure  *  @param  errorCode */public void  Seterrorcode (String errorcode)  {this. Errorcode = errorcode;} /** *  getting prompt error messages  *  @return  */public string geterroRmessage ()  {return errormessage;} /** *  set prompt error message  *  @param  errormessage */public void seterrormessage ( String errormessage)  {this. Errormessage = errormessage;} /** *  Get exception error message  *  @return  */public string getexceptmessage ()  {return  exceptmessage;} /** *  Setting exception error messages  *  @param  exceptmessage */public void setexceptmessage ( String exceptmessage)  {this. Exceptmessage = exceptmessage;}}

If the above object is converted to JSON format by Jackson, the initial letter will automatically become lowercase, what if I want to capitalize the first letter?

in the attribute is added @JsonProperty annotation, and in the corresponding setter, getter above plus @jsonignore, so you can, add the following code as follows:

Package com.evideostb.billsystem.module.model;import org.codehaus.jackson.map.annotate.jsonserialize ;import com.fasterxml.jackson.annotation.jsonignore;import  com.fasterxml.jackson.annotation.jsonproperty;/** *  response protocol Header  *  @author  zhangchuanzhao  * 2015-9-18 pm 3:12:58 */@JsonSerialize (include=jsonserialize.inclusion.non_null) public  class responseprotocol {//Error number:0  success &NBSP, other indicates failure @jsonpropertyprotected string  errorcode;//Tip Error Message @jsonpropertyprotected string errormessage;//exception error message @jsonpropertyprotected  string exceptmessage;/** *  get error number:0  success &NBSP, other indicates failure  *  @return  */@ Jsonignorepublic string geterrorcode ()  {return errorcode;} /** *  Set error number:0  success &NBSP, other indicates failure  *  @param  errorcode */@JsonIgnorepublic   Void seterrorcode (String errorcode)  {this.

Exceptmessage = exceptmessage;}}
