spring boot 运行时出现这样的问题：
1，解决办法：加上@EnableAutoConfiguration注解，最好使用 jdk1.8
这个解决办法我使用过了，没什么用

后面再pow.xml中加入

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

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

问题解决！！！
