Springboot Configuring MongoDB

1 using MAVEN to introduce MongoDB dependencies

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

2 configuring MongoDB, default DB is Test

spring.data.mongo.host=127.0.0.1
spring.data.mongo.port=27017
Spring.data.mongo.database=test

3 Developing PO entity classes

public class Item {
@Id
Private String ID;

private String name;

Private String Price;

/**getters and setters*/

}

4 implements the Mongorepository interface, which needs to specify a specific generic

Public interface Itemrepository extends Mongorepository<item, string> {
Item findbyname (String name);
}

5 Invocation Mode

public class Itemcontroller {
@Autowired
Private Itemrepository itemrepository;

@RequestMapping ("/additem")

@ResponseBody
public string AddItem (string paramstr) {
Jsonobject data = new Jsonobject ();
Item item = new Item ();
Item.setname ("Item 1");
Item.setprice ("5.95");
try {
Itemrepository.save (item);
} catch (Exception e) {
Data.put ("Error", "ADD item Error");
}
return data.tostring ();
}
