Integrate Spring Boot in an EAR project

Question

I have an existing war project created using spring boot. How to package it within an EAR which has an EJB module?

Is there any way to move the model and dao packages to EJB module and injecting it with WAR module?

Answer 1

You need a parent project that includes a war project, which will be your spring boot project, and an ear project just for making your ear.

Parent will need to have the spring boot as its parent :

<?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>

Your ear project is:

<?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>
