在Mongo驱动程序3.11.0中使用Spring Boot Starter Web依赖时出现Java . lang . nosuchmethod错误

Question

将Spring Boot Starter Web依赖项与最新的MongoDB驱动程序3.11.0一起使用会给出以下错误。当我切换到旧版本的Mongo驱动程序（如3.8.2）时，这工作正常。有什么想法吗？我应该排除 Mongo 依赖项吗？

如果我删除Spring靴依赖项，Mongo连接可以正常工作。

下面的pom:

Answer 1

Spring Boot存在一些依赖性问题。我通过以下方法解决了这个问题：

  <dependency>
      <groupId>org.mongodb</groupId>
      <artifactId>bson</artifactId>
       <version>3.11.0</version>
  </dependency>
  <dependency>
      <groupId>org.mongodb</groupId>
      <artifactId>mongodb-driver</artifactId>
      <version>3.11.0</version>
      <exclusions>
          <exclusion>
               <groupId>org.mongodb</groupId> 
               <artifactId>bson</artifactId>
           </exclusion>
      </exclusions>
  </dependency>
  <dependency>
      <groupId>org.mongodb</groupId>
      <artifactId>mongodb-driver-core</artifactId>
      <version>3.11.0</version>
  </dependency> 

Answer 2

你能试试这种依赖性吗

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

而不是

<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongodb-driver-sync</artifactId>
    <version>3.11.0</version>
</dependency>
