我正在尝试在我的Spring启动应用程序中集成apache log4j。这是我的build.gradle文件：
的build.gradle
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.4.3.RELEASE")
classpath 'mysql:mysql-connector-java:5.1.34'
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
jar {
baseName = 'spring-boot-sample'
version = '0.1.0'
}
repositories {
mavenCentral()
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {
// tag::jetty[]
compile("org.springframework.boot:spring-boot-starter-web") {
exclude module: 'spring-boot-starter-tomcat'
exclude module: 'spring-boot-starter-logging'
}
compile("org.springframework.boot:spring-boot-starter-jetty")
// end::jetty[]
// tag::actuator[]
compile("org.springframework.boot:spring-boot-starter-actuator")
// end::actuator[]
compile("org.springframework.boot:spring-boot-starter-log4j")
compile("org.springframework.boot:spring-boot-starter-data-jpa")
compile("mysql:mysql-connector-java:5.1.34")
testCompile("junit:junit")
testCompile("org.springframework.boot:spring-boot-starter-test")
}
每当我尝试构建项目时，我都会遇到构建失败。 我认为以下回购不可用：
https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-starter-log4j//spring-boot-starter-log4j-.pom
https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-starter-log4j//spring-boot-starter-log4j-.jar
以下是具有完整堆栈跟踪异常的完整构建输出：

我猜测解决这个问题的最后一个选项是将log4j库放在bin位置（最糟糕的方式）并在.classpath中提供 还有更好的办法吗？
答案 0 :(得分：3)
log4j是EOL，因此已从Spring Boot as of Spring Boot 1.4中删除。如果您想使用log4j，请使用org.springframework.boot:spring-boot-starter-log4j2
答案 1 :(得分：0)
在gradle依赖项中，您需要明确排除logback-classic。
