oracle ojdbc驱动程序抛出noclassdeffounderror:oracle/i18n/util/localemapper

gradle tomcat oracle spring java

Snæbjørn · 技术社区 · 6 年前

当在tomcat 8.5服务器(不是嵌入式tomcat)上运行时,在我的spring引导项目中使用oracleojdbc驱动程序时,我得到了以下错误

noclassdeffounderror:oracle/i18n/util/localemapper

如果我使用嵌入式tomcat运行它,一切都会正常工作。不幸的是,我需要它在一个外部容器上运行(我想它被调用了)

我的项目是从 https://start.spring.io/

除了Oracle驱动程序之外,其他都是默认的。

build.gradle公司

buildscript {
    ext {
        springBootVersion = '2.0.2.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse-wtp'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
apply plugin: 'war'

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()

    maven {
      credentials {
        username = oracleUser
        password = oraclePass
    }
   url 'https://www.oracle.com/content/secure/maven/content'
  }
}

configurations {
    providedRuntime
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('com.oracle.jdbc:ojdbc8:12.2.0.1')
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

我正在像这样运行spring工具套件(sts)的项目

我发现其他人也有同样的问题,比如

但我不知道他们在说什么。这是第一次使用Java和Spring、Oracle和Eclipse:

解决办法是按照建议去做 here 不要试图去理解它。把一些神奇的文件放在一个神奇的地方( src/main/resources/META-INF/services/ )当它开始工作时:/
