本文主要记录一下使用Morphia 2.2 进行开发（MongoDB 4.2 ）的基本步骤。省略MongoDB安装

本文主要记录基于Morphia最新版本2.2, MongDB4.2 的CRUD开发配置过程，仅供个人参考。

1. 基础工程

使用Idea 创建一个web工程，并加入Morphia 依赖。POM文件的配置如下：

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

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-test</artifactId>
	<scope>test</scope>
</dependency>

<!-- https://mvnrepository.com/artifact/dev.morphia.morphia/morphia-core -->
<dependency>
	<groupId>dev.morphia.morphia</groupId>
	<artifactId>morphia-core</artifactId>
	<version>2.2.1</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->
<dependency>
	<groupId>org.projectlombok</groupId>
	<artifactId>lombok</artifactId>
	<version>1.18.20</version>
	<scope>provided</scope>
</dependency>

Morphia的配置文件

@Configuration
public class MorphiaConfig {

    @Bean
    @ConditionalOnMissingBean(Datastore.class)
    public Datastore datastore(MongoProperties mongoProperties) {

        MongoClientSettings.Builder settingsBuilder = MongoClientSettings.builder();

        //用户凭证
        MongoCredential credential = MongoCredential.createCredential(mongoProperties.getUsername(),
                mongoProperties.getDatabase(), mongoProperties.getPassword());
        settingsBuilder.credential(credential);

        //服务器地址
        ServerAddress serverAddress = new ServerAddress(mongoProperties.getHost(), mongoProperties.getPort());
        settingsBuilder.applyToClusterSettings(b
