在 EAR 项目中集成 Spring Boot

Question

我有一个使用 spring 引导创建的现有 war 项目。如何将其打包到具有 EJB 模块的 EAR 中？

有什么方法可以将 model 和 dao 包移动到 EJB 模块并用 WAR 模块注入它？

Answer 1

您需要一个包含 war 项目的父项目，这将是您的 spring 启动项目，以及一个专门用于制作耳朵的耳朵项目。

父级需要将 spring 启动作为其父级：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

 <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.3.RELEASE</version>
  </parent>

  <groupId>com.greg</groupId>
  <artifactId>ear-example</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>pom</packaging>

  <properties>
        <myproject.version>1.0-SNAPSHOT</myproject.version>
  </properties>

  <name>ear-example</name>
  <modules>
    <module>example-ear</module>
    <module>example-war</module>
  </modules>

</project>

您的耳朵项目是：

<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>

  <parent>
    <groupId>com.greg</groupId>
    <artifactId>ear-example</artifactId>
    <version>1.0-SNAPSHOT</version>
  </parent>

  <artifactId>example-ear</artifactId>
  <packaging>ear</packaging>

  <dependencies>
    <dependency>
      <groupId>com.greg</groupId>
      <artifactId>example-war</artifactId>
      <version>${project.version}</version>
      <type>war</type>
    </dependency>
  </dependencies>

  <build>
   <plugins>
     <plugin>
        <artifactId>maven-ear-plugin</artifactId>
        <version>2.10.1</version>
        <configuration>
                <modules>
                        <webModule>
                                <groupId>com.greg</groupId>
                                <artifactId>example-war</artifactId>
                                <contextRoot>/appname</contextRoot>
                        </webModule>
                </modules>
        </configuration>
      </plugin>
    </plugins>
  </build>

</project>

你必须使用依赖管理系统。

它允许您设置不同于 spring-boot-starter-parent 的 Spring 引导 WAR 模块项目的父项目。它可以像任何其他项目一样将 WAR 项目包含到 EAR 中。

<dependencyManagement>
     <dependencies>
        <dependency>
            <!-- Import dependency management from Spring Boot -->
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-dependencies</artifactId>
            <version>1.5.2.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

...那么您将以通常的方式使用入门依赖项：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
</dependencies>

共享依赖项可以由根级 pom 指定，而单独的依赖项可能是一个模块边界。

Answer 3

我创建了一个多模块 gradle 项目，包括一个 spring RESTFul 网络服务 - EAR 应用程序名称是 - bluestone bluestone/settings.gradle -

rootProject.name = 'bluestone'
include ':bluestone-web'
include ':bluestone-core'
include ':bluestone-rest'

project (':bluestone-web').projectDir = new File('bluestone-web')
project (':bluestone-core').projectDir = new File('bluestone-core')
project (':bluestone-rest').projectDir = new File('bluestone-rest')

bluestone-rest 项目结构是 -

bluestone-rest/build.gradle

plugins {
    id 'war'
}

group 'com.bluestone.smart.rest'
version '1.0-SNAPSHOT'



dependencies {
    compile library.spring_context
    compile library.spring_web
    compile library.spring_beans
    compile library.spring_mvc
    providedCompile library.servlet_api
    testCompile library.junit

}

所有依赖项都是从公共 libraries.gradle 导入的。 common libraries.gradle is user ear bluestone/libraries.gradle

/* ============================================================================
   Library definitions for project 'Bluestone'
   ============================================================================
   Define here library dependencies and use them inside sub-modules build.gradle.

   Included from: "${rootProject.projectDir}/build.gradle"
   ============================================================================

 */
ext {

    library = [
            /* testing */
            junit: "junit:junit:4.12",
            log4j: "log4j:log4j:1.2.17",

            /* Spring libraries*/
            spring_context:     "org.springframework:spring-context:${spring_lib_version}",
            spring_aop:      "org.springframework:spring-aop:${spring_lib_version}",
            spring_beans:     "org.springframework:spring-beans:${spring_lib_version}",
            spring_orm:      "org.springframework:spring-orm:${spring_lib_version}",
            spring_web:      "org.springframework:spring-web:${spring_lib_version}",
            spring_mvc:                     "org.springframework:spring-webmvc:${spring_lib_version}",
            servlet_api:                     "javax.servlet:javax.servlet-api:4.0.1"

    ]
}

在 bluestone-rest 中，我创建了三个基本文件来测试示例 rest 消息 -

spring 配置名为 - BlueRestConfiguration.java

package com.bluestone.smart.rest.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ComponentScans;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = {"com.bluestone.smart.rest.resources", "com.bluestone.smart.rest.controller"})
public class BlueRestConfiguration {
}

初始化文件 - 命名为 - RestInit.java

package com.bluestone.smart.rest.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

import javax.servlet.ServletContext;

public class RestInit extends AbstractAnnotationConfigDispatcherServletInitializer {
    /**
     * Specify {@code @Configuration} and/or {@code @Component} classes for the
     * {@linkplain #createRootApplicationContext() root application context}.
     *
     * @return the configuration for the root application context, or {@code null}
     * if creation and registration of a root context is not desired
     */
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[] {BlueRestConfiguration.class};
    }

    /**
     * Specify {@code @Configuration} and/or {@code @Component} classes for the
     * {@linkplain #createServletApplicationContext() Servlet application context}.
     *
     * @return the configuration for the Servlet application context, or
     * {@code null} if all configuration is specified through root config classes.
     */
    @Override
    protected Class<?>[] getServletConfigClasses() {
        return null;
    }

    /**
     * Specify the servlet mapping(s) for the {@code DispatcherServlet} &mdash;
     * for example {@code "/"}, {@code "/app"}, etc.
     *
     * @see #registerDispatcherServlet(ServletContext)
     */
    @Override
    protected String[] getServletMappings() {
        return new String[] {"/"};
    }
}

休息服务 API - 命名 - GreetingsController.java

package com.bluestone.smart.rest.resources;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class GreetingsController {
    @RequestMapping(path = "/greeting", method = RequestMethod.GET)
    public String greetings(){
        return "Welcome Spring Rest!";
    }
}

最终使用 -

构建此 EAR 应用程序

gradlew clean build

并部署到 WildFly 应用程序上，然后使用邮递员调用此服务 -
