求助！！！renren-fast后台工程启动报错

目前项目用的pom文件就是码云上renren-fast的pom文件。 百度后都说是springboot和druid版本不匹配造成的，但是修改后已就报错。 java.lang.NoClassDefFoundError: org/springframework/boot/bind/RelaxedDataBinder at org.springframework.boot.autoconfigure.EnableAutoConfigurationImportSelector.getExcludeAutoConfigurationsProperty(EnableAutoConfigurationImportSelector.java:179) at org.springframework.boot.autoconfigure.EnableAutoConfigurationImportSelector.getExclusions(EnableAutoConfigurationImportSelector.java:172) at org.springframework.boot.autoconfigure.EnableAutoConfigurationImportSelector.selectImports(EnableAutoConfigurationImportSelector.java:87) at org.springframework.context.annotation.ConfigurationClassParser$DefaultDeferredImportSelectorGroup.process(ConfigurationClassParser.java:888) at org.springframework.context.annotation.ConfigurationClassParser$DeferredImportSelectorGrouping.getImports(ConfigurationClassParser.java:874) at org.springframework.context.annotation.ConfigurationClassParser$DeferredImportSelectorGroupingHandler.processGroupImports(ConfigurationClassParser.java:801) at org.springframework.context.annotation.ConfigurationClassParser$DeferredImportSelectorHandler.process(ConfigurationClassParser.java:771) at org.springframework.context.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:188) at org.springframework.context.annotation.ConfigurationClassPostProcessor.processConfigBeanDefinitions(ConfigurationClassPostProcessor.java:319) at org.springframework.context.annotation.ConfigurationClassPostProcessor.postProcessBeanDefinitionRegistry(ConfigurationClassPostProcessor.java:236) at org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanDefinitionRegistryPostProcessors(PostProcessorRegistrationDelegate.java:275) at org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors(PostProcessorRegistrationDelegate.java:95) at org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors(AbstractApplicationContext.java:706) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:532) at org.springframework.boot.web.servlet.context.ServletWebServerApplicationContext.refresh(ServletWebServerApplicationContext.java:141) at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:747) at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:397) at org.springframework.boot.SpringApplication.run(SpringApplication.java:315) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1226) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1215) at io.renren.RenrenApplication.main(RenrenApplication.java:19) Caused by: java.lang.ClassNotFoundException: org.springframework.boot.bind.RelaxedDataBinder at java.net.URLClassLoader$1.run(URLClassLoader.java:372) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:360) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 21 common frames omitted
