我是 Spring Boot 的新手,我想将默认记录器更改为 log4j2,因为它比 logback 具有更高的吞吐量。
这是我的 Gradle 脚本。如您所见,我使用的是 Spring Boot 2.0.3,为了禁用默认记录器,我在 Spring Boot Web 之后使用了排除模块(logback 和 spring boot starter logger)。我正在脚本的底部编译 log4j。
buildscript {
ext {
springBootVersion = '2.0.3.RELEASE'
}
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
group = 'app'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8
repositories {
mavenCentral()
jcenter()
}
ext {
vaadinVersion = '8.4.1'
}
dependencies {
compile('org.springframework.boot:spring-boot-starter-data-rest')
providedCompile 'javax.servlet:javax.servlet-api:3.1.0'
compile('org.springframework.boot:spring-boot-starter-security')
compile('org.springframework.boot:spring-boot-starter-thymeleaf')
compile('org.springframework.boot:spring-boot-starter-web') {

}

}
dependencyManagement {
imports {
mavenBom "com.vaadin:vaadin-bom:${vaadinVersion}"
}
}
这是我的 Spring Boot 应用程序。
package app.clothapp;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class ClothappApplication {
public static void main(String[] args) {
SpringApplication.run(ClothappApplication.class, args);
}
}
但是,当我运行 Spring Boot 应用程序时,它向我提供了 AbstractMethodError。我读过其他一些 SO 问题,显然有些类自上次编译以来已经发生了不适当的更改。有人可以提供一些帮助吗?

谢谢。
