在SpringBoot中禁用Logback

问题描述： LoggerFactory 不是Logback 的LoggerContext，但是Logback却会在classpath上。需要禁用掉Logback，猜测是pom中的引用出现了问题

原来的pom文件如下：

        </plugins>
    </build>
</project>

解决方法如下：

需要手动地解除spring-boot-starter和spring-boot-starter-web中的那些logging。需要将pom文件中的上述两项进行如下改造：

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter</artifactId>
  <exclusions>
    <exclusion>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-logging</artifactId>
    </exclusion>
  </exclusions>
</dependency>

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-web</artifactId>
  <exclusions>
    <exclusion>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-logging</artifactId>
    </exclusion>
  </exclusions>
</dependency>

这样就解决了冲突问题啦！
