异常信息

2017-09-02 18:06:37.223 [main] ERROR o.s.boot.SpringApplication  - Application startup failed
java.lang.IllegalStateException: Could not evaluate condition on org.springframework.boot.actuate.autoconfigure.EndpointWebMvcAutoConfiguration$EndpointWebMvcConfiguration due to org/springframework/boot/context/embedded/ServletRegistrationBean not found. Make sure your own configuration does not rely on that class. This can also happen if you are @ComponentScanning a springframework package (e.g. if you put a @ComponentScan in the default package by mistake)

错误显示一直说 ClassNotFoundException 但是maven库中已经加了该jar包

<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>

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

把下面这个包去掉就可以了，原因不明

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-spring-boot-starter-jaxws</artifactId>
    <version>3.1.7</version>
</dependency>
