java – 无法在JBoss 6.4 EAP中部署Spring Boot EAR
作者：互联网

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
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

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.
解决方法:
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<子部署>
<?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.
