Could not initialize class

Spring项目启动失败：JSON包导入即报错 Could not initialize class com.fasterxml.jackson.databind.ObjectMapper

           <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-databind</artifactId>
                <version>2.12.4</version>
            </dependency>
            <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-annotations</artifactId>
                <version>2.12.4</version>
            </dependency>
            <dependency>

，项目一直启动报错，查原因发现jar包依赖的版本不对，改成同一版本就好了
