SpringBoot:无法从以下候选人中找到一个主班

spring-boot

我使用Spring Initializer,嵌入式Tomcat,Thymeleaf模板引擎生成了Spring Boot
Web应用程序,使用的技术包括:Spring Boot 1.4.2.RELEASE,Spring 4.3.4.RELEASE,Thymeleaf
2.1.5.RELEASE,Tomcat Embed 8.5.6。 ,Maven 3,Java 8

我有一个SpringBoot应用程序。有这两个类:

@Profile("!war")
@SpringBootApplication
@Import({SecurityConfig.class ,PersistenceConfig.class, ServiceConfig.class})
public class BookApplication {

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

@Profile("war")
@Import({SecurityConfig.class ,PersistenceConfig.class})
@SpringBootApplication
public class BookApplicationWar extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(BookApplicationWar.class);
    }

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

}

我用这个命令发动战争

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

但是我得到了这个错误:

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.5.2.RELEASE:repackage (default) on project book: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:1.5.2.RELEASE:repackage failed: Unable to find a single main class from the following candidates [com.tdk.BookApplication, com.tdk.BookApplicationWar] -> [Help 1]

如果您有多个主类,则需要在每个概要文件中显式配置主类

<profiles>
    <profile>
        <id>profile1</id>
        <properties>
          <spring.boot.mainclass>com.SomeClass</spring.boot.mainclass>
        </properties>
    </profile>
    <profile>
        <id>profile2</id>
        <properties>
          <spring.boot.mainclass>com.SomeOtherClass</spring.boot.mainclass>
        </properties>
    </profile>
</profiles>

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>1.5.2.RELEASE</version>
    <executions>
      <execution>
        <goals>
          <goal>repackage</goal>
        </goals>
        <configuration>
          <mainClass>${spring.boot.mainclass}</mainClass>
        </configuration>
      </execution>
    </executions>
    ...
</plugin>

参见 spring-boot:repackage
