问题描述
这可能不是常见的情况，因为我们基本上不会同时使用 EJB 和 SpringBoot ，并且在Google上几乎找不到相关主题.
This may not be a common scenario, as we would not use EJB and SpringBoot at the same time basically, and almost no related topic could be found on Google.
问题
当我将 javaee-api 添加到SpringBoot项目 pom.xml 中时，默认的SpringBoot测试将失败.
Issue
When I add javaee-api into a SpringBoot project pom.xml, the default SpringBoot test would fail.
详细信息
我的项目几乎是一个空的Spring原型项目(从start.spring.io开始)，其中包含Spring入口类 App.java ，Spring测试类 AppTest.java 和 pom.xml .我从原型中更改的是添加了 javaee-api 依赖项.请参见 pom.xml 依赖项:
Detail
My Project is almost an empty Spring prototype project(started from start.spring.io), containing a Spring entrance class App.java, a Spring test class AppTest.java and a pom.xml.What I changed from the prototype is I added javaee-api dependency.See pom.xml dependencies:
<dependencies>
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<!-- We need to include the javax.servlet API specs, the implementation will be provided by Wildfly / JBoss-->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<scope>provided</scope>
</dependency>
</dependencies>
结果
运行测试 AppTest.java 会失败.一旦我删除了 javaee-api 工件，一切都很好.添加 javaee-api 工件时的错误堆栈:
Result
Run test AppTest.java would fail. And once I remove the javaee-api artifact, it's all good.The error stack when javaee-api artifact is added:

摘要
我将在同一项目中使用 SpringBoot2 和 EJB3 ，但是看起来SpringBoot不允许添加 javaee-api 依赖项.我很好奇他们是否可以一起工作以及为什么会发生冲突.互联网上没有太多信息，所以我发布了这个问题，希望值得讨论.
Summary
I'm going to use SpringBoot2 and EJB3 in a same project, but looks SpringBoot do not allowed to add javaee-api dependency. I'm curious whether they can work together and why the conflict occurs.No much information on the Internet, so I post this question, hope it worth to discuss.
推荐答案
那不是真的.Spring Boot通过其RI(休眠验证器6 )使用JSR 380 2.0(Bean验证2.0).
That's not really what happens. Spring Boot uses JSR 380 2.0 (Bean Validation 2.0) via its RI (Hibernate Validator 6).
NoSuchMethodError 表示您添加了不兼容的API版本.如果您不能使用验证API 2.0(我相信Java EE 8)，请考虑同时使用Spring Boot 1.5 .
The NoSuchMethodError indicates that you've added an incompatible API version. If you cannot use validation API 2.0 (Java EE 8 I believe), consider using Spring Boot 1.5 in the meantime.
这篇关于在pom.xml中添加javaee-api依赖项时SpringBoot测试失败的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
