搜索“conflict” 发现有多处冲突，进行一一排包，例如，再次执行mvn dependency:tree -Dverbose 命令发现冲突已解决。
<dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.3</version> <exclusions> <exclusion> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> </exclusion> </exclusions> </dependency>
总结：
出现下述异常时，先查找StandardServletEnvironment 类看能否查找到，如果能则是jar包冲突，否则则是缺少依赖jar包，然后再继续对症下药。
Caused by: java.lang.ClassNotFoundException: org.springframework.web.context.support.StandardServletEnvironment
