SpringBoot：定義pom.xml文件中的主類

我已經使用Spring初始化程序，嵌入式Tomcat，Thymeleaf模板引擎生成了Spring Boot Web應用程序。使用的技術：Spring Boot 1.4.2.RELEASE，Spring 4.3.4。 RELEASE，Thymeleaf 2.1.5.RELEASE，Tomcat的嵌入8.5.6時，Maven 3，Java的8 我有這個pom.xml文件，SpringBoot：定義pom.xml文件中的主類

，我使用這個命令

mvn clean package -DskipTests -Dspring.profiles.active=pebloc,war -DAPPKEY=pebloc

POM產生戰爭.xml：

編輯問題以包含您的主要課程。 –

Maven輪廓沒有任何關係Spring配置文件。

你有兩個Maven概況：罐子，戰爭

你要麼使用：

mvn clean package -Pjar

或

mvn clean package -Pwar

你所得到的錯誤，而建設的假象，因爲pom需求：

<start-class>your.app.entry.point.Main</start-class>

屬性元素內。

無論Maven配置文件如何，我都建議只有一個開始類。

類似：

的pom.xml：

... 
<modelVersion>4.0.0</modelVersion> 
<groupId>com.asimio.cloud</groupId> 
<artifactId>zuul-server</artifactId> 
<version>0-SNAPSHOT</version> 
<packaging>${packaging.type}</packaging> 
... 
<properties> 
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> 
    <java.version>1.8</java.version> 
    <start-class>your.app.entry.point.Main</start-class> 
    <packaging.type>jar</packaging.type> 
... 
<profiles> 
    <profile> 
    <id>war</id> 
    <properties> 
     <packaging.type>war</packaging.type> 
    </properties> 
    <dependencies> 
     <dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-tomcat</artifactId> 
     <scope>provided</scope> 
     </dependency> 
    </dependencies> 
... 
    </profile> 
</profiles> 
...

Main.java：

package your.app.entry.point; 
... 
@SpringBootApplication 
@Import({SecurityConfig.class ,PersistenceConfig.class, ServiceConfig.class}) 
public class App extends SpringBootServletInitializer { 

    @Override 
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { 
    return builder.sources(App.class); 
    } 

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

無需Spring配置文件。這神器現在可以使用兩種Maven輪廓建成並運行或者使用：

java -jar .....

建設這件神器的罐子時

或

爲部署到一個servlet容器war文件時所建使用-Pwar Maven配置文件。

Maven的配置文件和配置文件春季是兩個不同的概念。

您還應該使用war配置文件運行Maven，以便使用正確的匹配值設置spring.boot.mainclass屬性。

將-Pwar添加到命令行以激活war Maven配置文件。

mvn clean package -DskipTests -Pwar -Dspring.profiles.active=pebloc,war -DAPPKEY=pebloc
