好吧,所以看起来没有检测到SpringBootServletInitializer,因为它位于EAR中的JAR内部,而不是WAR.我做的是制作一个新模块并将其包含在我的WAR中.这包含一个带有services文件夹的META-INF目录.该services文件夹有一个文件(javax.servlet.ServletContainerInitializer),其内容为org.springframework.web.SpringServletContainerInitializer.然后尝试部署WAR,但失败并出现以下情况：

Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS018104: Deployment error processing SCI for jar: test-1.0.0-SNAPSHOT.jar
        at org.jboss.as.web.deployment.ServletContainerInitializerDeploymentProcessor.loadSci(ServletContainerInitializerDeploymentProcessor.java:202)
        ... 7 more
Caused by: java.lang.ClassCastException: org.springframework.web.SpringServletContainerInitializer cannot be cast to javax.servlet.ServletContainerInitializer
        at org.jboss.as.web.deployment.ServletContainerInitializerDeploymentProcessor.loadSci(ServletContainerInitializerDeploymentProcessor.java:194)
        ... 7 more

同样,看起来Servlet API与另一个相冲突 – 但是我可以告诉它只有类路径上的那个(我甚至将它作为此测试提供的范围).

原版的

目前我在JBoss 6.4 EAP中部署Spring-Boot(1.3.2.RELEASE)EAR时遇到了一些问题. EAR文件只是将一个瘦的WAR和所有JAR包装在/ lib文件夹中.

我之前已经进行了部署WAR文件所需的更改,但遗憾的是我们遇到了部署必须是EAR的要求.

部署为WAR

要将应用程序部署为WAR,我更改了以下内容：

的pom.xml

    <!-- JavaEE 7 for JPA 2.1 -->
    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-api</artifactId>
        <version>7.0</version>
    </dependency>

    <!-- Exclude Tomcat -->
    <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>

    <!-- Include Servlet 3 -->
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.0.1</version>
    </dependency>

JBoss的部署,structure.xml

<?xml version="1.0"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
    <deployment>
        <exclude-subsystems>
            <subsystem name="jpa"/>
        </exclude-subsystems>
        <exclusions>
            <module name="javaee.api"/>
        </exclusions>
    </deployment>
</jboss-deployment-structure>

Application.java

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    private static final Class<Application> APPLICATION_CLASS = Application.class;

    public static void main(String[] args) {
        SpringApplication.run(APPLICATION_CLASS, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(APPLICATION_CLASS);
    }

}

这些更改工作正常,我现在可以将WAR部署到JBoss 6.4.

部署为EAR

这就是麻烦开始的地方.我使用maven-ear-plugin创建了一个新模块来构建EAR文件：

<build>
    <finalName>my-application</finalName>
    <plugins>
        <plugin>
            <artifactId>maven-ear-plugin</artifactId>
            <version>2.10.1</version>
            <configuration>
                <version>6</version>
                <skinnyWars>true</skinnyWars>
                <defaultLibBundleDir>lib</defaultLibBundleDir>
                <fileNameMapping>no-version</fileNameMapping>
                <modules>
                    <webModule>
                        <groupId>com.test.app</groupId>
                        <artifactId>my-application</artifactId>
                        <bundleFileName>my-application.war</bundleFileName>
                        <context-root>/my-app</context-root>
                    </webModule>
                </modules>
            </configuration>
        </plugin>
    </plugins>
</build>

我还在/ src / main / application / META-INF下添加了jboss-deployment-structure.xml,以便它包含在EAR中(它需要处于最高级别).尝试部署这会导致“成功”,但JBoss从不尝试在EAR中部署WAR.似乎需要一个web.xml.

所以看看文档,似乎我需要定义一个如下的web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>com.test.app.Application</param-value>
    </context-param>

    <servlet>
        <servlet-name>appServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextAttribute</param-name>
            <param-value>org.springframework.web.context.WebApplicationContext.ROOT</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>appServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

现在有一些额外的配置,如果我想要下载到Servlet 2.5 – 但我不想这样做.

尝试部署此结果会导致以下异常：

    10:29:40,586 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/company-api-entity]] (ServerService Thread Pool -- 56) JBWEB000289: Servlet appServlet threw load() exception: java.lang.ClassCastException: org.springframework.web.servlet.DispatcherServlet cannot be cast to javax.servlet.Servlet

            at org.jboss.threads.JBossThread.run(JBossThread.java:122)

这似乎是加载的servlet版本不匹配,但我似乎无法验证它是(或排除它).我已经尝试将范围设置为提供(因此JBoss版本接管),但这会导致以下错误：

11:18:47,141 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/company-api-entity]] (ServerService Thread Pool -- 52) JBWEB000289: Servlet appServlet threw load() exception: java.util.MissingResourceException: Can't find bundle for base name javax.servlet.LocalStrings, locale en_IE

显然,它使用的是JBoss 3.0 servlet规范,但似乎缺少实际的servlet 3.0 JAR.

有什么东西我不见了吗？ WAR实际上是否需要web.xml,还是有其他方式？我正在尝试甚至可能吗？

任何帮助将不胜感激.

最佳答案 修复了这个问题.从WAR部署开始,我制作了一个额外的EAR模块.我不应该使用skinnyWar,而是将所有JAR保留在WAR中.这允许Spring正确引导Spring Boot servlet.

这具有以下配置：

<build>
    <finalName>my-application</finalName>
    <plugins>
        <plugin>
            <artifactId>maven-ear-plugin</artifactId>
            <version>2.10.1</version>
            <configuration>
                <modules>
                    <webModule>
                        <groupId>com.test.app</groupId>
                        <artifactId>my-application</artifactId>
                        <bundleFileName>my-application.war</bundleFileName>
                        <context-root>/my-app</context-root>
                    </webModule>
                </modules>
            </configuration>
        </plugin>
    </plugins>
</build>

我还确保在我的父模块(根pom)中没有编译范围的依赖项.

然后我确保在我的EAR中有以下文件：

的src / main /应用/ META-INF / jboss的部署,structure.xml

虽然这是在我的WAR中,但我遇到的主要问题是我仍在使用< deployment>而不是

<?xml version="1.0"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
    <sub-deployment name="my-application.war">
        <exclude-subsystems>
            <subsystem name="jpa"/>
        </exclude-subsystems>
        <exclusions>
            <module name="javaee.api"/>
        </exclusions>
    </sub-deployment>
</jboss-deployment-structure>

这正确地排除了javaee.api模块和jpa子系统.

在此之后,EAR正确部署到JBoss.
