当我尝试加载一个简单的SpringBoot项目时，它失败并出现以下错误：

java.lang.NoSuchMethodError： org.springframework.util.ObjectUtils.unwrapOptional（Ljava /郎/对象;）Ljava /郎/对象; 在 org.springframework.validation.DataBinder。（DataBinder.java:179）在 org.springframework.boot.bind.RelaxedDataBinder。（RelaxedDataBinder.java:83）在 org.springframework.boot.bind.PropertiesConfigurationFactory.doBindPropertiesToTarget（PropertiesConfigurationFactory.java:253）在 org.springframework.boot.bind.PropertiesConfigurationFactory.bindPropertiesToTarget（PropertiesConfigurationFactory.java:240）在 org.springframework.boot.context.config.ConfigFileApplicationListener.bindToSpringApplication（ConfigFileApplicationListener.java:241）在 org.springframework.boot.context.config.ConfigFileApplicationListener.postProcessEnvironment（ConfigFileApplicationListener.java:197）在 org.springframework.boot.context.config.ConfigFileApplicationListener.onApplicationEnvironmentPreparedEvent（ConfigFileApplicationListener.java:182）在 org.springframework.boot.context.config.ConfigFileApplicationListener.onApplicationEvent（ConfigFileApplicationListener.java:168）在 org.springframework.context.event.SimpleApplicationEventMulticaster.doInvokeListener（SimpleApplicationEventMulticaster.java:172）在 org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener（SimpleApplicationEventMulticaster.java:165）在 org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent（SimpleApplicationEventMulticaster.java:139）在 org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent（SimpleApplicationEventMulticaster.java:127）在 org.springframework.boot.context.event.EventPublishingRunListener.environmentPrepared（EventPublishingRunListener.java:74）在 org.springframework.boot.SpringApplicationRunListeners.environmentPrepared（SpringApplicationRunListeners.java:54）在 org.springframework.boot.SpringApplication.prepareEnvironment（SpringApplication.java:325）在 org.springframework.boot.SpringApplication.run（SpringApplication.java:296）在 org.springframework.boot.SpringApplication.run（SpringApplication.java:1118）在 org.springframework.boot.SpringApplication.run（SpringApplication.java:1107）在com.phoneBook.Main.main（Main.java:30）

我从阅读帖子中了解到这是与依赖项兼容的问题。我试图使用不同版本而没有成功。

它不是重复：Spring Boot Application Unable to start?

我添加了那里显示的依赖项，但仍然遇到了同样的错误。

你能帮帮我吗？

根据错误，我们可以看到spring-context和spring-core之间的版本不匹配：

178:  public DataBinder(@Nullable Object target, String objectName) {
179:     this.target = ObjectUtils.unwrapOptional(target);
180:     this.objectName = objectName;
181:  }

要检查每个版本的运行方式：

mvn dependency:tree | grep 'spring-context\|spring-core'

你可以更进一步检查实际的打包版本，它应该与maven所示的相同：

jar tf SpringProject-1.0-SNAPSHOT.jar | grep 'spring-context\|spring-core'

如果显示：

BOOT-INF / LIB /弹簧上下文4.3.14.RELEASE.jar
BOOT-INF / LIB /弹簧芯4.3.14.RELEASE.jar

并且错误仍然存在，请发布完整的源示例和步骤以重现它。
