【问题描述】:
我正在尝试编写一个独立的可执行 jar (fat jar)。我正在使用 spring boot gradle 插件并编写一个 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 ex application-common 等。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: "${rootDir}/deployTasks.gradle"
springBoot {
mainClass = "storm.Application"
}
dependencies {
compile project(':common')
compile project(':adapter')
compile project(':persistence')
compile group: 'org.springframework.boot', name: 'spring-boot-starter-actuator', version: '1.1.8.RELEASE'
compile group : 'org.springframework.boot',name: 'spring-boot-autoconfigure', version : '1.1.8.RELEASE'
compile group: 'org.springframework.boot', name: 'spring-boot-starter-data-jpa', version: '1.1.8.RELEASE'
}
application-common_db.yml 中的数据库规范
database:
host: localhost
port: 3306
schema: subscriptions
username: root
password: root
autoconnect:
maxReconnects: 3
initialTimeout: 2
timeout:
connectTimeout: 0
socketTimeout: 0
failover:
host: localhost
port: 3306
queriesBeforeRetryMaster: 50
secondsBeforeRetryMaster: 30
spring:
datasource:
driverClassName: com.mysql.jdbc.Driver
url: jdbc:mysql://${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
我不确定如何解决此错误。任何人都可以建议这里出了什么问题,为什么我会得到 nullPointerException。
感谢您的帮助。
谢谢
