在我的 POM 中，我添加了依赖项 String 4.2.9.RELEASE、Spring boot 1.5.1.RELEASE 和 FasterXML / jackson 2.8.6，并出现以下错误：

您不能将 Spring Framework 4.2.x 与 Spring Boot 1.5.x 一起使用。如文档系统要求中所述，Spring Boot 1.5.1 需要 Spring Framework 4.3.6 或更高版本。

您可以通过使用 Spring Boot 的依赖管理来避免此类问题。通过使用spring-boot-starter-parent作为你的 pom 的父母：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.1.RELEASE</version>
</parent>

或者通过将spring-boot-dependenciesbom 导入到你的 pom 中：

<dependencyManagement>
     <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-dependencies</artifactId>
            <version>1.5.1.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

您可以在不指定版本的情况下声明对依赖管理中包含的任何内容的依赖。
