目标:获得与spring-boot-starter-parent完美工作的Spring Boot应用程序模块,与我们自己的自定义父POM一起工作。我正在遵循这一指南,很抱歉地说,我不能让这充分发挥作用。https://www.surasint.com/spring-boot-with-no-parent-example/。
具体地说,使用spring-boot-starter作为父pom时,一切都很好。
有了我们自己的父pom,Spring Boot应用程序就坏了。
我有一个项目设置与三个模块和我自己的父POM。有很多原因需要这样做(父pom使用Maven概要文件,并根据这些概要文件设置重要的数据库变量)。
我使用的是Spring Boot1.5.9、Maven3.3和Java8.
理论上我完全同意它应该在没有spring-boot-starter-parent的情况下工作。然而,当使Spring Boot模块只继承父pom而不继承spring-boot-starter-parent时,会出现以下异常(对我来说非常奇怪)。

该项目在IntelliJ中是完全绿色的,编译正常。只有在启动Spring Boot应用程序时才会出现这些错误。正如我所解释的,Spring boot应用程序模块现在缺少了以前的一些东西。这里的任何建议都是最有帮助的!
具体来说,您需要导入什么(在Maven dependency-tags中)以使模块能够访问与它从spring-boot-starter-parent而不是您自己的自定义父级继承时完全相同的东西和所有东西?如果不是通过纯粹的直觉来猜测您的依赖关系(这在我的情况下显然是失败的),而是有一个引用依赖关系检查列表来确保您的模块可以访问完全相同的内容,就像直接从spring-boot-starter-parent继承一样,那就太棒了。
到目前为止,我纯粹凭直觉在Spring Boot模块中添加了以下内容(上面称为“Web”)
<!-- === [Spring Boot Starter] === -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>

很明显,缺少了spring-boot-starter作为父级所存在的一些东西。而且,奇怪的是,其余可能的spring-boot-starter依赖项似乎与项目完全无关(比如云连接器、Twitter连接器、mongodb和相关)。我添加了所有远程相关只是为了测试,但下面的错误仍然存在。任何建议或帮助都是非常感谢的。
作为参考,这里是父POM:

原因:java.lang.noClassDefFounderRorr:org/springframework/data/rest/core/config/repositoryCorsRegistry
我不知道如何解释这一点。这是否意味着我们在正确的轨道上,只需要添加一些额外的depedency,或者依赖项不必要地添加,可能会导致不必要的问题?
现在缺少的类是https://docs.Spring.io/Spring-data/rest/docs/current/api/org/springframework/data/rest/core/config/repositorycorsregistry.html,我不确定应该添加什么作为依赖项,以便在Spring boot中以正确的方式访问这个类。当然,我不愿意通过普通的spring framework依赖项(如https://mvnrepository.com/artifact/org.springframework/spring-web/5.0.3.release)添加它,因为这通常会导致版本问题(spring Boot包括相关的springframeworkd,应该完全通过spring Boot来管理,据我所知,我已经被告知过很多次了)。
更新2:也许不符合更好的判断--而且因为我愿意测试任何东西,直到一切正常工作--我添加了下面的库,这些库中有当前缺少的类。
当然,只有在仔细检查https://mvnrepository.com/artifact/org.springframework.Boot/spring-boot/1.5.9.release以确定Spring Boot版本使用的核心org.springframework库之后,才能完成此操作。
<dependency>
<groupId>org.springframework</groupId>

</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.3.13.RELEASE</version>

我现在得到了一个不同的例外:
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.web.filter.OrderedHttpPutFormContentFilter]: Factory method 'httpPutFormContentFilter' threw exception; nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.fasterxml.jackson.databind.ObjectMapper

at org.springframework.http.converter.json.Jackson2ObjectMapperBuilder.build(Jackson2ObjectMapperBuilder.java:588) ~[spring-web-4.3.13.RELEASE.jar:4.3.13.RELEASE]
这导致我添加了以下依赖项(再次仔细检查了上面的Spring Boot引用,以查看它使用的特定库的版本):
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.9.4</version>
</dependency>
然而,可悲和奇怪的是--同样的例外仍然存在。这意味着我们陷入了死胡同,因为https://mvnrepository.com/artifact/org.springframework.boot/spring-boot/1.5.9.release中没有更多的逻辑库可以包含。
所以让我们退一步,看看我们需要什么。
就是这样。所有核心服务和JPA逻辑都在公共库模块中,这是web Spring Boot app模块和worker模块所需要的。
干杯!
Spring Boot Starter父级不能成为父级POM的父级是不是有什么原因?我看到它在您的自定义父级中被注释掉了。
此设置应该可以工作:

老实说,应该就是这样。然后您创建了一个自定义父pom,它从Spring Boot Starter父级中正确地继承了所有内容,并且您可以提供所有您自己的配置文件和其他您希望应用程序模块继承的自定义。
您应该不必经历重新创建Spring Boot应用程序的依赖关系树的所有麻烦,正如您所注意到的,这样做基本上是依赖关系管理的地狱般的场景。
