**1. mongod和mongo**

**mongod官方文档描述地址：[https://docs.mongodb.com/manual/reference/program/mongod.exe/index.html][https_docs.mongodb.com_manual_reference_program_mongod.exe_index.html]**

**[https://docs.mongodb.com/manual/reference/program/mongod/\#bin.mongod][https_docs.mongodb.com_manual_reference_program_mongod_bin.mongod]**

Synopsis
    mongod is the primary daemon process for the MongoDB system. It handles data requests, 
    manages data access, and performs background management operations.
    
    This document provides a complete overview of all command line options for mongod. 
    These command line options are primarily useful for testing: In common operation, 
    use the configuration file options to control the behavior of your database.

**mongo官方文档描述地址：[https://docs.mongodb.com/manual/reference/program/mongo/][https_docs.mongodb.com_manual_reference_program_mongo]**

Description
    mongo is an interactive JavaScript shell interface to MongoDB, which provides a powerful interface for system 
    administrators as well as a way for developers to test queries and operations directly with the database. 
    mongo also provides a fully functional JavaScript environment for use with a MongoDB. 
    The mongo shell is part of the MongoDB distributions.

2. 异常：java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException: invalid hexadecimal representation of an ObjectId: \[180d3afd-5b3d-4924-855a-31d1d8787b5c\]

异常背景：通过UUID生成id插入到mongodb数据库，数据保存成功，但是通过ObjectId取出的时候报错

![20190628180745309.png][]

异常原因：ObjectId 使用12 字节的存储空间，每个字节两位十六进制数字，是一个24 位的字符串

解决方案：id使用mongodb默认方式

3. 异常：org.springframework.data.mongodb.UncategorizedMongoDbException: Exception authenticating MongoCredential\{mechanism=SCRAM-SHA-256, userName='zsx', source='mongodb\_test', password=<hidden>, mechanismProperties=\{\}\}; nested exception is com.mongodb.MongoSecurityException: Exception authenticating MongoCredential\{mechanism=SCRAM-SHA-256, userName='zsx', source='mongodb\_test', password=<hidden>, mechanismProperties=\{\}\}

异常背景：使用springboot连接mongodb，mongodb配置如下

spring: 
      data: 
        mongodb:
          database: mongodb_test
          host: 127.0.0.1
          port: 27017
          username: zsx
          password: 1234

原因：MongoClientFactory在解析配置配置文件中的password时，将纯数字当成一个char处理了

// org.springframework.boot.autoconfigure.mongo.MongoClientFactory
    private MongoCredential getCredentials(MongoProperties properties) {
    		if (!hasCustomCredentials()) {
    			return null;
    		}
    		String username = properties.getUsername();
    		String database = getValue(properties.getAuthenticationDatabase(),
    				properties.getMongoClientDatabase());
    		char[] password = properties.getPassword();
    		return MongoCredential.createCredential(username, database, password);
    	}

uri方式映射时，密码

解决方法：

**1. 通过uri方式连接**

spring: 
      data: 
        mongodb:
          uri: mongodb://zsx:1234@localhost:27017/mongodb_test

**2. 修改密码，不要设置为纯数字即可**
