顯示的錯誤信息：找不到Tomcat，打開Tomcat失敗。

查詢過程：本項目是在manager裏面的pom.xml內配置的Tomcat插件：

1. <!-- 配置tomcat插件 -->

2. <build>

3. <plugins>

4. <plugin>

5. <groupId>org.apache.tomcat.maven</groupId>

6. <artifactId>tomcat7-maven-plugin</artifactId>

7. <configuration>

8. <path>/</path>

9. <port>8080</port>

10. </configuration>

11. </plugin>

12. </plugins>

13. </build>

而manager的Tomcat是引用的parent裏面的pom.xml內配置的Tomcat插件：

1. <!-- 配置Tomcat插件 -->

2. <plugin>

3. <groupId>org.apache.tomcat.maven</groupId>

4. <artifactId>tomcat7-maven-plugin</artifactId>

5. <version>2.2</version>

6. </plugin>

原因：是jdk版本的問題，Tomcat7默認使用的jdk是jdk1.7。我原來配置的是1.8，所以一直報錯。

後來在 windows-preference-java-Installed JREs 裏面配置jdk版本爲1.7，項目運行成功。

項目運行成功：
