springboot学习笔记(五)springboot MongoTemplate的使用
首先导入相关依赖:
org.mongodb
mongo-java-driver
org.mongodb.morphia
morphia
0.109
配置文件 application.properties 配置 连接参数：
spring.data.mongodb.host=xxx
spring.data.mongodb.port=xxx
spring.data.mongodb.database=xxx相关实体(偷个懒，直接拿的项目中的实体):
package com.springboot.Test_myspringboot.entity;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Date;
import org.hibernate.validator.constraints.NotEmpty;
import org.mongodb.morphia.annotations.Entity;

@Entity
@Document(collection = "ym_literature")

public String home() {

return "helloMongo!";
}
}
调用接口：
localhost:6636/helloMongo查看控制台：
数据库名为：wymlib
书籍标题为：王阳明
ok 测试成功！
