hadoop-common-2.5.0和springfox-spring-web-2.9.2.jar,springfox-schema-2.9.2.jar冲突解决

spring boot 项目想要连接hive库的时候 需要导入两个jar包hadoop-common-2.5.1.jar和hive-jdbc-1.2.1

在导入的之后原来的项目启动报错具体如下 

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name \'apiDocumentationScanner\' defined in URL [jar:file:/E:/ideaSpace/imps-qdhk/imps-run/target/imps/WEB-INF/lib/springfox-spring-web-2.9.2.jar!/springfox/documentation/spring/web/scanners/ApiDocumentationScanner.class]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name \'apiListingScanner\' defined in URL [jar:file:/E:/ideaSpace/imps-qdhk/imps-run/target/imps/WEB-INF/lib/springfox-spring-web-2.9.2.jar!/springfox/documentation/spring/web/scanners/ApiListingScanner.class]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name \'apiModelReader\' defined in URL [jar:file:/E:/ideaSpace/imps-qdhk/imps-run/target/imps/WEB-INF/lib/springfox-spring-web-2.9.2.jar!/springfox/documentation/spring/web/scanners/ApiModelReader.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name \'cachingModelProvider\' defined in URL [jar:file:/E:/ideaSpace/imps-qdhk/imps-run/target/imps/WEB-INF/lib/springfox-schema-2.9.2.jar!/springfox/documentation/schema/CachingModelProvider.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name \'defaultModelProvider\' defined in URL [jar:file:/E:/ideaSpace/imps-qdhk/imps-run/target/imps/WEB-INF/lib/springfox-schema-2.9.2.jar!/springfox/documentation/schema/DefaultModelProvider.class]: Unsatisfied dependency expressed through constructor parameter 2; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name \'cachingModelDependencyProvider\' defined in URL [jar:file:/E:/ideaSpace/imps-qdhk/imps-run/target/imps/WEB-INF/lib/springfox-schema-2.9.2.jar!/springfox/documentation/schema/CachingModelDependencyProvider.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name \'defaultModelDependencyProvider\': Lookup method resolution failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class 

 

1.百度搜索两个jar包冲突怎么办？没有解决方法。

2.百度搜索如何在idea上看pom依赖图？项目依赖过多，最后虽然看到了依赖相关但是没有红线。

3.尝试exclusion一些jar包可是并不知道哪些，只能随便去试，试了几个也没有用。

4.第二天问下一微信研发群里面的怎么解决，没人回，应该是没人遇到过。

5.尝试百度怎样解决jar包冲突，俗话说授人以鱼不如授人以渔，提供了思路找类

6.Unsatisfied dependency expressed through constructor parameter 0;网上说是由于在类里面定义了“有参构造方法”，这样的话就会覆盖原先的“无参构造方法”，所以会出现此异常。

发现异常类里面引用的类可能在其他jar包里面也有引用，找异常类的导入的相似类如下

 

 发现好多都有Google相关 的于是在maven库https://mvnrepository.com/里发现其子依赖也有Google相关的jar如下

 

 于是直接手动去除如下3个，项目可以重新跑起来了。
