exception is java.lang.NoClassDefFoundError: com/fasterxml/jackson/datatype/jsr310/ser/ZoneIdSerial

背景：

 SpringBoot工程引入序列化工具：

     <dependency>
          <groupId>com.fasterxml.jackson.core</groupId>
          <artifactId>jackson-databind</artifactId>
          <version>2.8.1</version>
      </dependency>
      <dependency>
          <groupId>com.fasterxml.jackson.core</groupId>
          <artifactId>jackson-annotations</artifactId>
          <version>2.8.1</version>
      </dependency>

  工程运行时报错：

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.fasterxml.jackson.datatype.jsr310.JavaTimeModule]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: com/fasterxml/jackson/datatype/jsr310/ser/ZoneIdSerializer

 原因分析：

 springboot自身的框架中引入了jackson框架，包冲突，可以升级成以下版本，即可解决问题：

<!--Jackson required包-->
<dependency>
   <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-core</artifactId>
   <version>2.11.2</version>
</dependency>
<dependency>
   <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-databind</artifactId>
   <version>2.11.2</version>
</dependency>
<dependency>
   <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-annotations</artifactId>
   <version>2.11.2</version>
