springboot启动mongoDB报错之禁用mongoDB自动配置问题
作者：lv_hang515888
这篇文章主要介绍了springboot启动mongoDB报错之禁用mongoDB自动配置问题,具有很好的参考价值,希望对大家有所帮助,如有错误或未考虑完全的地方,望不吝赐教
springboot启动mongoDB报错之禁用mongoDB自动配置
错误信息如下：
springboot自动配置了支持mongodb。
在启动springboot时会自动实例化一个mongo实例。
所以自己配置的话，需要禁用掉springboot的自动配置。
@SpringBootApplication(exclude = {MongoAutoConfiguration.class,MongoDataAutoConfiguration.class})这个注解可以禁用springboot自带的配置。
如下图：
springboot整合MongoDB时碰到的问题
1.账号总是不对，导致查不出数据，报错Auth…权鉴错误
这次，我也是第一次接触MongoDB，非常的生疏
springboot整合MongoDB，要在properties文件中配置账号
mongodb基本语法：
use DATABASE_NAME; --创建数据库
show dbs; --查看我们所有的库，注意，我们刚创建的库，如果没有数据，是不会被显示的
show users; --查看当前库所有拥有的账号
db.createCollection(name, options) --在当前数据库中创建集合
show tables --查看当前库中有哪些集合
--在当前数据库中创建用户并设置密码及权限
db.createUser(
... {
... user : "aaa",
... pwd : "123456",
... roles: [ { role : "readWrite", db : "springboot" }]
... }
... )
通过上面的基础铺垫：
1.首先我们要登录MongoDB数据库
用管理员权限运行cmd
进入我们安装的MongoDB的bin目录下执行命令
mongo
即可登录MongoDB数据库
2.创建数据库
use springboot;
3.创建数据库对应的账号
创建一个springboot账号，对springboot数据库拥有读写权限
db.createUser(
... {
... user : "springboot",
... pwd : "123456",
... roles: [ { role : "readWrite", db : "springboot" }]
... }
... )4.在springboot库中创建集合user
db.createCollection("user"); --创建集合user
show tables; --查看当前库中所有的集合
--- 并给集合user添加一条数据
db.user.insert({
"user_name":"pzj",
"note":"用户pzj",
"roles":[{
"role_name": "vip_user",
"note": "会员"
}]
})到此，MongoDB的数据库初始化完成。
2.springboot工程代码中的配置
主要说下properties中的配置，pom里面引入的包我就不说了
spring.data.mongodb.host=127.0.0.1 spring.data.mongodb.username=springboot spring.data.mongodb.password=123456 spring.data.mongodb.database=springboot spring.data.mongodb.port=27017 logging.level.org.springframework.data.mongodb.core=DEBUG
3.查询时遇见的错误
No converter found capable of converting from org.bson.types.ObjectId to type Long异常
这个问题很好解决
我们在创建实体类对应数据库中的集合user时，把id设置成了Long型，导致的报错
我们只要把id类型改成String即可。
在MongoDb里要求每个文档都需要有_id 字段，java类中有如下情况会被映射为_id字段
如果1个字段加上了 @Id (org.springframework.data.annotation.Id)注解，那么将bean保存到数据库时就会把该字段映射为文档中的_id字段
如果java对象中没有 @Id 注解，名字为id 的字段将会被映射为文档中的_id字段
所以，也可以看出，我们的MongoDB数据，是不需要我们人为的添加主键id字段的
这个和以往的mysq等关系型数据库有所不同
它会自动给我们生成一个_id字段，作为集合的主键，标识一条数据
