代码使用

增加MgTemplate的Class文件

package cn.ok96.common;
 
import org.bson.Document;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.stereotype.Component;
 
import com.mongodb.client.MongoCollection;
 
@Component("mgTemplate")  
public class MgTemplate {  
  
    @Autowired  
    private MongoTemplate mongoTemplate;  
 
   /**
     * 添加数据
     * @param collectionName
     * @return
     */
    public MongoCollection<Document> getCollection(String collectionName) {  
        return mongoTemplate.getCollection(collectionName);  
    }  
  
    /**
     *
     * 查找数据
     * @param imageId
     * @return Image实体类
     */
    public Image findOne(String imageId) {  
     Query query = new Query()
              .addCriteria(Criteria.where("imgId").is(imageId));
        return mongoTemplate.findOne(query, Image.class);
    }
}

在使用类中引用-插入数据

public class imclass {
  @Autowired
  private MgTemplate mgTemplate;
  public String test(String rawPass) {
    String id = new ObjectId().toString();
    Document document = new Document();  
    document.put("img","dasdasd");  
    document.put("imgId", id);  
    document.put("createTime", DateUtil.forFull(new Date()));  
    mgTemplate.getCollection("imgInfo").insertOne(document);
  }
}

在使用类中引用-查找数据

创建实体类

package cn.ok96.model;
 
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
 
import lombok.Data;
 
@Data
@Document(collection = "imgInfo")
public class Image {
 
  private String imgId;
  private String img;
  private String createTime;
  public String getImgId() {
    return imgId;
  }
  public void setImgId(String imgId) {
    this.imgId = imgId;
  }
  public String getImg() {
    return img;
  }
  public void setImg(String img) {
    this.img = img;
  }
  public String getCreateTime() {
    return createTime;
  }
  public void setCreateTime(String createTime) {
    this.createTime = createTime;
  }
}

在使用类中使用

public class imclass {
  @Autowired
  private MgTemplate mgTemplate;

  @Override
  public String getFaceForMongo(String id) {
    Image face=mgTemplate.findOne(id);
    return face.getImg();
  }
}
