创建修改代码

新建一个实例类：Connector

代码：com/jinwei/S6_dsw_mongodb_rest/Connector.java

package com.jinwei.S6_dsw_mongodb_rest;
import org.springframework.data.annotation.Id;


public class Connector {

    @Id private String id;

    // 定义实例类需要 set-get 的各种属性
    private String cacert;
    private String description;
    private String sellDataID;
    private String buyDataID;

    // get and set: cacert
    public String getCacert() {
        return cacert;
    }

    public void setCacert(String cacert) {
        this.cacert = cacert;
    }

    // get and set: description
    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    // get and set: sellDataID
    public String getSellDataID() {
        return sellDataID;
    }

    public void setSellDataID(String sellDataID) {
        this.sellDataID = sellDataID;
    }

    // get and set: buyDataID
    public String getDuyDataID() {
        return buyDataID;
    }

    public void setDuyDataID(String buyDataID) {
        this.buyDataID = buyDataID;
    }
}

定义对应于实体类的仓库类：ConnectorRepository

格式：{实体类名称-驼峰命名}+Repository(后缀)

代码：com/jinwei/S6_dsw_mongodb_rest/ConnectorRepository.java

package com.jinwei.S6_dsw_mongodb_rest;
import java.util.List;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.data.repository.query.Param;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;


@RepositoryRestResource(collectionResourceRel = "people", path = "people")
public interface ConnectorRepository extends MongoRepository<Connector, String> {

    List<Connector> findByLastName(@Param("name") String name);

}

点击主类运行
