java.lang.IllegalStateException:org.springframework.boot.autoconfigure.jdbc.JndiDataSourceAutoConfiguration上的错误处理条件

Question

我正在尝试编写一个独立的可执行jar(胖罐).我正在使用spring boot gradle插件并编写SpringBoot App来执行此操作.

这是我的Application.java文件

@Configuration
@EnableAutoConfiguration
@EnableRabbit
@EntityScan("persistence.domain")
@EnableJpaRepositories("persistence.repository")
@ComponentScan(basePackages = {"common","service"})
public class Application {

     public static void main(final String[] args) {
            final SpringApplicationBuilder appBuilder = new SpringApplicationBuilder(
                Application.class);
            appBuilder.profiles("common", "common_db").run(args);
          }

      @Bean
      @Primary
      @ConfigurationProperties(prefix = "spring.datasource")
      public DataSource primaryDataSource() {
        return DataSourceBuilder.create().build();
      }
}

我在yml文件中指定了属性.对于前申请 - 常见等.在运行Application.java时出现错误:

这是我的build.gradle

def projects= [
    ":common",
    ":persistence",
    ":adapter"

]

buildscript {
repositories {
  mavenCentral()
  maven { url 'http://repo.spring.io/snapshot' }
  maven { url 'http://repo.spring.io/milestone' }
}
dependencies { classpath group: 'org.springframework.boot', name: 'spring-boot-gradle-plugin', version: springBootVersion }

}

apply plugin: 'spring-boot'
apply plugin: 'maven-publish'
apply from: "${rootDir}/deployTasks.gradle"

springBoot {
mainClass = "storm.Application"
}

dependencies {
    compile project(':common')
    compile project(':adapter')
    compile project(':persistence')
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-actuator', version: '1.1.8.RELEASE'
    compile group : 'org.springframework.boot',name: 'spring-boot-autoconfigure', version : '1.1.8.RELEASE'
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-data-jpa', version: '1.1.8.RELEASE'

}

数据库规范,如application-common_db.yml

database:
host: localhost
port: 3306
schema: subscriptions
username: root
password: root
autoconnect:
maxReconnects: 3
initialTimeout: 2
timeout:
connectTimeout: 0
socketTimeout: 0
failover:
host: localhost 
port: 3306
queriesBeforeRetryMaster: 50
secondsBeforeRetryMaster: 30


spring:
datasource:
driverClassName: com.mysql.jdbc.Driver
url: jdbc:mysql://${database.host}:${database.port},${database.failover.host}:${database.failover.port}/${database.schema}?${database.properties}
username: ${database.username}
password: ${database.password}
continueOnError: true
initialize: false
initialSize: 0
timeBetweenEvictionRunsMillis: 5000
minEvictableIdleTimeMillis: 5000
removeAbandonedTimeout: 60
removeAbandoned: true
minIdle: 0

我不知道如何解决此错误.你能告诉我这里出了什么问题以及为什么我会得到nullPointerException.

感谢帮助.

谢谢

这是由不匹配的Spring Boot依赖项引起的.检查您的类路径以查找有问题的资源.您已明确包含版本1.1.8.RELEASE,但您还包括其他3个项目.那些可能包含不同的Spring Boot版本,导致此错误.
