springdata开发MongoDB示例

使用IDEA初始化springboot+springdata框架，开发mongodb示例，pom.xml文件如下

主要实现思路

Mongotemplate

首先创建一个实体，用来对应mongodb中的文档

  1 //@Document(collection = "test_stock")
  2 @Document
  3 public class Stock {
  4 
  5     private String id;
  6     private String ts_code;
  7     private String trade_date;
  8     private float open;
  9     private float high;
 10     private float low;
 11     private float close;
 12     private float pre_close;
 13     private float change;
 14     private float pct_chg;
 15     private Long vol;
 16     private float amount;
 17 
 18     public Stock() {
 19     }
 20 
 21     public String getId() {
 22         return id;
 23     }
 24 
 25     public void setId(String id) {
 26         this.id = id;
 27     }
 28 
 29     public String getTs_code() {
 30         return ts_code;
 31     }
 32 
 33     public void setTs_code(String ts_code) {
 34         this.ts_code = ts_code;
 35     }
 36 
 37     public String getTrade_date() {
 38         return trade_date;
 39     }
 40 
 41     public void setTrade_date(String trade_date) {
 42         this.trade_date = trade_date;
 43     }
 44

 51     }
 52

 71     }
 72 
 73     public void setClose(float close) {
 74         this.close = close;
 75     }
 76 
 77     public float getPre_close() {
 78         return pre_close;

 96 
 97     public void setPct_chg(float pct_chg) {
 98         this.pct_chg = pct_chg;
 99     }
100 
101     public Long getVol() {
102         return vol;
103     }
104 
105     public void setVol(Long vol) {
106         this.vol = vol;
107     }
108 
109     public float getAmount() {
110         return amount;
111     }
112 
113     public void setAmount(float amount) {
