在 pom.xml 中添加 java-api 依赖项时，Spring Boot 测试失败

Question

这可能不是常见的情况，因为我们不会同时使用 EJB 和 SpringBoot基本上，在Google.

上几乎找不到相关话题

问题
当我将 javaee-api 添加到 Spring 启动项目 pom.xml 时，默认的 Spring 启动测试将失败。

详情
我的项目几乎是一个空的Spring原型项目（从start.spring.io开始），包含一个Spring入口classApp.java，一个Spring测试class AppTest.java 和一个 pom.xml。我对原型所做的更改是添加了 javaee-api 依赖项。请参阅 pom.xml 个依赖项：

<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：

总结
我打算在同一个项目中使用 SpringBoot2 和 EJB3，但看起来 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。网上资料不多，所以才post这个问题，希望大家一起讨论。

Answer 1

looks SpringBoot do not allowed to add javaee-api

事实并非如此。 Spring Boot 通过其 RI (Hibernate Validator 6) 使用 JSR 380 2.0 (Bean Validation 2.0)。

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。

在 pom.xml 中添加 java-api 依赖项时，Spring Boot 测试失败
