SpringCloud----->在springboot项目中跑起来控制台项目

在springboot项目中跑起来控制台项目:
一个springboot的控制台项目:
    (1)、用spring-boot-starter替换掉spring-boot-starter-web,不然项目就会以web项目的方式启动.
    (2)、如果项目中有其他依赖了spring-boot-starter-web,必须exclude掉,例:
          <dependency>
              <groupId>com.xxxx.xxx</groupId>
              <artifactId>xxxx</artifactId>
              <exclusions>
                  <exclusion>
                      <groupId>org.springframework.boot</groupId>
                      <artifactId>spring-boot-starter-web</artifactId>
                  </exclusion>
              </exclusions>
          </dependency>   
    (3)、在项目打包的时候,也要exculde掉web相关依赖。
          <build>
              <plugins>
                  <plugin>
                      <groupId>org.springframework.boot</groupId>
                      <artifactId>spring-boot-maven-plugin</artifactId>
                      <configuration>
                          <excludeArtifactIds>tomcat*</excludeArtifactIds>
                          <excludeArtifactIds>spring-web</excludeArtifactIds>
                          <excludeGroupIds>io.springfox</excludeGroupIds>
                          <excludes>
                              <exclude>
                                  <groupId>org.springframework.boot</groupId>
                                  <artifactId>spring-boot-starter-web</artifactId>
                              </exclude>
                              <exclude>
                                  <groupId>org.springframework.boot</groupId>
                                  <artifactId>spring-boot-starter-tomcat</artifactId>
                              </exclude>
                          </excludes>
                      </configuration>
                  </plugin>
              </plugins>
          </build>   
   
  然后将主入口文件写成:
        
    import org.springframework.boot.CommandLineRunner;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;

    @SpringBootApplication
    public class CanalclientApplication implements CommandLineRunner {

        public static void main(String[] args) {

            System.out.println("     Hello Springboot!!!!!");
            SpringApplication.run(CanalclientApplication.class, args);
        }

        @Override
        public void run(String... args) throws Exception {
            System.out.println("     This is console line!!!!!");
        }
    }
    
 就成了一个单独的命令行程序。
