1 使用maven引入mongodb依賴
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
2 配置mongodb，默認db為test
spring.data.mongo.host=127.0.0.1
spring.data.mongo.port=27017
spring.data.mongo.database=test
3 開發po實體類
public class Item {
@Id
private String id;
private String name;
private String price;
/**getters and setters*/
}
4 實現MongoRepository接口，該接口需要指定具體的泛型
public interface ItemRepository extends MongoRepository<Item, String> {
Item findByName(String name);
}
5 調用方式
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("商品1");
item.setPrice("5.95");
try {
itemRepository.save(item);
} catch(Exception e) {
data.put("error", "Add item error");
}
return data.toString();
}
