mongoDB（3） 设置主键

通过注释【@Id】设置主键，如果不设置主键，mongoDB会自动生成主键。

import org.springframework.data.annotation.Id;

public static class OrderComsumeDTO{@Idprivate String orderNo;private String JnlNo;private String dateTime;public String getOrderNo() {return orderNo;}public void setOrderNo(String orderNo) {this.orderNo = orderNo;}public String getJnlNo() {return JnlNo;}public void setJnlNo(String jnlNo) {JnlNo = jnlNo;}public String getDateTime() {return dateTime;}public void setDateTime(String dateTime) {this.dateTime = dateTime;}}

增/删/查

@Overridepublic void insert(OrderComsumeDTO obj) {this.save(obj);}@Overridepublic OrderComsumeDTO selectByPrimaryKey(String id) {OrderComsumeDTO dto = this.findById(id);return dto;}@Overridepublic int deleteByPrimaryKey(String id) {return this.deleteById(id);}
