已解决:将以下内容添加到POM.xml

Resolved:Add the following to the POM.xml

    <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>
            <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-log4j</artifactId>
    </dependency>

推荐答案

从 spring-boot-starter-web 中排除 logback-classic 和 spring-boot-starter-actuator 为我工作

compile("org.springframework.boot:spring-boot-starter-web:1.1.10.RELEASE") {
    exclude module: "spring-boot-starter-tomcat"
    exclude module: "spring-boot-starter-logging"
    exclude module: "logback-classic"
}
compile("org.springframework.boot:spring-boot-starter-actuator:1.1.10.RELEASE") {
    exclude module: "logback-classic"
}
