Maven에서 Java Spring 세팅하기

※ 본 항목은 업데이트 중입니다.

- pom.xml 설정하기

Spring Project를 개발하기 위해서는, pom.xml에 packaging과 property, dependency를 추가 해 주어야 한다.

  - packaging을 war로 설정한다.

<packaging>war</packaging>

  - property에서 Spring Framework version을 설정한다.

    spring.version에 대한 정보는 Github(https://github.com/spring-projects/spring-framework/wiki/Spring-Framework-Versions) 혹은 Spring 공식 사이트(https://spring.io/projects/spring-framework#learn)에서 확인할 수 있다.

<properties>
   <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
   <spring.version> 4.3.5.RELEASE</spring.version>
</properties>

  - <dependencies>에서 spring framework에 필요한 spring-context, spring-webmvc, spring-test dependency들을 추가해 준다.

<dependencies>
   <!-- Spring 프로젝트에 필요한 dependency -->
   <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>${spring.version}</version>
   </dependency>

   <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>${spring.version}</version>
   </dependency>

   <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-test</artifactId>
      <version>${spring.version}</version>
   </dependency>

  - JSP를 추가적으로 이용하고자 한다면, JSTL과 EL dependency들을 추가해준다.

<!-- Servlet JSP 사용을 위한 JSTL dependency -->
<dependency>
   <groupId>javax.servlet</groupId>
   <artifactId>javax.servlet-api</artifactId>
   <version>3.1.0</version>
   <scope>provided</scope>
</dependency>

<dependency>
   <groupId>javax.servlet.jsp</groupId>
   <artifactId>javax.servlet.jsp-api</artifactId>
   <version>2.3.1</version>
   <scope>provided</scope>
</dependency>

<dependency>
   <groupId>jstl</groupId>
   <artifactId>jstl</artifactId>
   <version>1.2</version>
</dependency>

  - Database 통신을 위해 PlatformTransactionManager와 JDBC, SQL Driver(여기에서는 MySQL), Connection Pool(여기에서는 DBCP2)을 추가한다.

<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-jdbc</artifactId>
   <version>${spring.version}</version>
</dependency>

<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-tx</artifactId>
   <version>${spring.version}</version>
</dependency>

<dependency>
   <groupId>mysql</groupId>
   <artifactId>mysql-connector-java</artifactId>
   <version>5.1.45</version>
</dependency>

<!-- basic data source -->
<dependency>
   <groupId>org.apache.commons</groupId>
   <artifactId>commons-dbcp2</artifactId>
   <version>2.1.1</version>
</dependency>

  - 파일 전송을 원한다면, Apache Commons File Upload와 IO를 추가한다.

<!-- Apache Commons FileUpload -->
   <dependency>
      <groupId>commons-fileupload</groupId>
      <artifactId>commons-fileupload</artifactId>
      <version>1.3.1</version>
   </dependency>

   <!-- Apache Commons IO -->
   <dependency>
      <groupId>commons-io</groupId>
      <artifactId>commons-io</artifactId>
      <version>2.4</version>
   </dependency>


</dependencies>

  - JDK 버전과 tomcat 버전을 추가해준다.

<build>
   <plugins>
      <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-compiler-plugin</artifactId>
         <version>3.6.1</version>
         <configuration>
            <source>1.8</source>
            <target>1.8</target>
         </configuration>
      </plugin>
      
      <plugin>
         <groupId>org.apache.tomcat.maven</groupId>
         <artifactId>tomcat7-maven-plugin</artifactId>
         <version>2.1</version>
         <configuration>
            <charset>UTF-8</charset>
            <uriEncoding>UTF-8</uriEncoding>
            <port>8080</port>
            <path>/</path>
         </configuration>
      </plugin>
   </plugins>
</build>

- Servlet 3.0 미만에서 web.xml 설정하기

  전통적인 Spring Framework에서는 해당 프로젝트의 /src/main/webapp/WEB-INF 폴더에 web.xml 파일을 추가함으로서 Application Context를 등록할 수 있다. web.xml은 tomcat과 같은 was가 읽어서 등록시킨다.

  web.xml은 아래와 같이 설정한다.

<?xml version="1.0" encoding="UTF-8"?>
<web-app>

    <display-name>Spring JavaConfig Sample</display-name>
    <context-param>
        <param-name>contextClass</param-name>
        <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
    </context-param>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>examples.daoexam.config.ApplicationConfig</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>mvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextClass</param-name>
            <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
        </init-param>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>examples.daoexam.config.WebMvcContextConfiguration</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

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


</web-app>
