Spring

提供一個 all-in-one 的開發環境(設定), 基本上是下面幾個要點組成, 所以不一定要用 [spring initializr] 產生:

  • pom.xml

      <parent>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-parent</artifactId>
          <version>版本號碼</version>
          <relativePath/>
      </parent>
    
      <dependencies>
          <dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-web</artifactId>
          </dependency>
    
          <!-- 開發階段用 -->
          <dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-tomcat</artifactId>
              <scope>provided</scope>
          </dependency>    
          <dependency>
              <!-- 偵測檔案變動自動重起 Tomcat -->
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-devtools</artifactId>
              <scope>runtime</scope>
              <optional>true</optional>
          </dependency>
      </dependencies>
    
      <build>
          <plugins>
              <plugin>
                  <groupId>org.springframework.boot</groupId>
                  <artifactId>spring-boot-maven-plugin</artifactId>
              </plugin>
          </plugins>
      </build>
  • 傳統 Java application class

      @SpringBootApplication
      public class SpringApp {
          public static void main(String[] args) {
              SpringApplication.run(SpringApp.class, args);
          }
      }

也不需要 mvnw,直接下 mvn spring-boot:run 就行。
