spring boot的Bean，Controller以及Repository的创建

首先，创建一个Bean类

/**

* File Name: Person.java

* Date: 2016年3月14日下午3:33:06  

*/

importjava.io.Serializable;

importjava.util.Date;

importjavax.persistence.Column;

importjavax.persistence.Entity;

importjavax.persistence.GeneratedValue;

importjavax.persistence.GenerationType;

importjavax.persistence.Id;

importjavax.persistence.Table;

importjavax.persistence.Temporal;

importjavax.persistence.TemporalType;

/**

* ClassName: Person

* date: 2016年3月14日 下午3:33:06

* Description:

*

*@version 

*@sinceJDK 1.8

*/

@Entity

@Table(name ="person")

publicclassPersonimplementsSerializable {

      @Id

      @GeneratedValue(strategy = GenerationType.AUTO)

      @Column(name ="personid")

      privatelongpersonId;

      

      privateStringname;

      

      privateintage;

      

      privateStringidCard;

      

      @Temporal(TemporalType.TIMESTAMP)

      privateDatebirthday;

      

      privateStringnationality;

      publicDate getBirthday() {

            returnbirthday;

      }

      publicvoidsetBirthday(Datebirthday) {

            this.birthday=birthday;

      }

      publicString getNationality() {

            returnnationality;

      }

      publicvoidsetNationality(Stringnationality) {

            this.nationality=nationality;

      }

      publiclonggetPersonId() {

            returnpersonId;

      }

      publicvoidsetPersonId(longpersonId) {

            this.personId=personId;

      }

      publicString getName() {

            returnname;

      }

      publicvoidsetName(Stringname) {

            this.name=name;

      }

      publicintgetAge() {

            returnage;

      }

      publicvoidsetAge(intage) {

            this.age=age;

      }

      publicString getIdCard() {

            returnidCard;

      }

      publicvoidsetIdCard(StringidCard) {

            this.idCard=idCard;

      }

}

创建controller

/**

* File Name: PersonController.java

* Date: 2016年3月14日下午3:43:07

*/

importorg.springframework.beans.factory.annotation.Autowired;

importorg.springframework.web.bind.annotation.RequestMapping;

importorg.springframework.web.bind.annotation.RequestMethod;

importorg.springframework.web.bind.annotation.RequestParam;

importorg.springframework.web.bind.annotation.RestController;

/**

* ClassName: PersonController

* date: 2016年3月14日 下午3:43:07

* Description:

*

*@version 

*@sinceJDK 1.8

*/

@RestController

publicclassPersonController {

      

      @Autowired

      privatePersonHandlerpersonHandler;

      

      @RequestMapping(value ="/api/person/queryperson/", method = RequestMethod.POST)

      publicObject queryPerson(

                  @RequestParam(value ="nationality", required =true) Stringnationality

                  ){

            returnpersonHandler;

      }

}

创建handler

/**

* File Name: PersonHandler.java

* Date: 2016年3月14日下午3:49:01

*/

importjava.util.List;

importorg.springframework.beans.factory.annotation.Autowired;

importorg.springframework.stereotype.Component;

importcom.google.gson.FieldNamingPolicy;

importcom.google.gson.Gson;

importcom.google.gson.GsonBuilder;

importcom.google.gson.JsonArray;

importcom.google.gson.JsonObject;

importcom.google.gson.JsonParser;

importcom.huifenqi.privilege.context.domain.Person;

importcom.huifenqi.privilege.dao.PersonRepository;

importcom.huifenqi.privilege.utils.GsonUtils;

/**

* ClassName: PersonHandler

* date: 2016年3月14日 下午3:49:01

* Description:

*

*@version 

*@sinceJDK 1.8

*/

@Component

publicclassPersonHandler {

      

      @Autowired

      privatePersonRepositorypersonRepository;

      

      publicObject queryPerson(Stringnationality){

            List<Person>persons=personRepository.findPersonByNationality(nationality);

            Gsoninstance=newGsonBuilder()

                  .serializeNulls()

                  .setDateFormat("yyyy-MM-dd HH:mm:ss")

                  .setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES)

                  .create();

            JsonArrayjs=newJsonArray();

            for(Personperson:persons) {

                  Stringjson=instance.toJson(person);

                  JsonParserparser=newJsonParser();

                  JsonObjectresJo=parser.parse(json).getAsJsonObject();

                  js.add(resJo);

            }

            returnjs;        

      }

      

}

创建repository

/**

* File Name: PersonRepository.java 

* Date: 2016年3月14日下午4:01:21 

*/

importjava.util.List;

importorg.springframework.data.jpa.repository.Query;

importorg.springframework.data.repository.CrudRepository;

importorg.springframework.stereotype.Repository;

importcom.huifenqi.privilege.context.domain.Person;

/**

* ClassName: PersonRepository

* date: 2016年3月14日 下午4:01:21

* Description:

* 

*@version 

*@sinceJDK 1.8

*/

@Repository

publicinterfacePersonRepositoryextendsCrudRepository<Person, Long> {

      

      @Query("select p from Person p where nationality=?1" )

      publicList<Person> findPersonByNationality(Stringnationality);

}
