无法启动Spring启动服务器

Question

我是春季启动的新手,当我尝试启动服务器时,我得到以下异常.我知道这与依赖冲突有关,但仍无法解决.我正在使用maven来管理我的依赖项.请帮助

 Exception in thread "main" java.lang.IllegalArgumentException:
 LoggerFactory is not a Logback LoggerContext but Logback is on the
 classpath. Either remove Logback or the competing implementation
 (class org.slf4j.impl.Log4jLoggerFactory) Object of class

已解决:将以下内容添加到POM.xml中

    <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>

    </exclusions>

Answer 1

若不计的logback经典的弹簧引导启动的Web和弹簧引导起动器为我工作

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"
}

Answer 2

将此添加到您的 build.gradle

configurations.all {
        exclude group: 'org.springframework.boot', module: 'spring-boot-starter-tomcat'
        exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
        exclude group: 'org.springframework.boot', module: 'logback-classic'
}

Answer 3

最终通过排除Logback依赖并显式添加log4j依赖解决了这个问题
